Product usedKS PERMAGLIDE® cylindrical plain bearingbush, design PAP … P10

FunctionFire dampers must function reliably. If there is a fire, the lamellae of the fire damper must open smoothly and correctly.Environmental influences such as heat, cold, dirt or dust must not impede the function of the lamellae. If used frequently – or indeed rarely – this correct opening must not be impeded. Jamming caused by corrosi-on, dirt or the influence of certain tempera-tures must be prevented.

Bearing with KS PERMAGLIDE® P10 plain bearing bushesKS PERMAGLIDE® P10 plain bearings, which are implemented in pairs, are an ideal solution for the bearing of the lamellae in fire dampers.The maintenance-free KS PERMAGLIDE® P10 plain bearings prevent the bearing from cor-roding and freezing solid, and prevent the lubricant from dripping out due to heat. The bearing clearance may not become too low, e.g. due to high temperatures, as this can lead to the lamellae becoming stuck. The reliable function of the fire damper – even after long periods of use – is guaranteed by using KS PERMAGLIDE® P10 plain bearings.

Advantage: Reliable function of the bearing thanks to KS PERMAGLIDE® P10 plain bearings• Impervious to temperature, dirt and dust• Maintenance-free, even when used very

frequently or rarely• Protected against corrosion

1.1 Bearing of the lamellae in fire dampers Sector: Fire safety technology, building technology



Description of materialKS PERMAGLIDE® P10 – robust and reliable• Universally usable plain bearing material

for dry and lubricated applications• High rigidity• Durability• High chemical resistance• Good emergency running properties• Material: Lead bronze sintered onto a

steel base, friction-minimising additives PTFE and lead.

KS PERMAGLIDE® P10 offers the following advantages over comparable lead-free plain bearing products:• Higher thermal conductivity• Good chemical resistance• Good transfer of lubricant onto the

interacting sliding partner• Good passivation of the interacting

sliding partner• Impervious to high edge loading

Fire damper Ventilation system

In damp environments, in particular, this sliding layer system provides outstanding protection against corrosion. Moreover, lead and PTFE are extremely non-absorbent. Absorption of the surrounding fluids with consequent swelling of the materials is prevented, as is chemical damage to inter-acting sliding partners. The result is dimen-sional stability and optimum corrosion protection during use.

Application descriptionIn normal operation, the lamellae of the fire damper are closed and are never opened, or if so, then very rarely. Fire dampers are installed in building venti-lation systems in order to prevent fire and smoke spreading via ventilation lines. In the event of fire, fire dampers are opened so that toxic fumes can be extracted. Fire dampers are sometimes mandatory as safety components according to § 14 of the German Model Building Ordinance (MBO). Fire dampers are also used for normal venti-lation in building technology.

1.2 Bearing of the shaft journal in maintenance-free isolating valvesSector: Chemical industry, building technology,industrial and process technology

Product usedKS PERMAGLIDE® cylindrical plain bearing bushing, type PAP … P10/P11.The KS PERMAGLIDE® materials P10 (with steel back) or P11 (with bronze back) are used, depending on the aggressiveness of the gas or liquid.

FunctionIsolating valves regulate by increasing and decreasing the flow of liquids and gases in pipelines. The installed plain bearings are constantly exposed to the influence of che-micals and high or extremely low tempera-tures. Liquids cause constant vibrations on the valve, amongst other things. The bearing must not become stuck due to corrosion or the influence of certain temperatures. If used frequently – or indeed rarely – the function of the isolating valve must not be impeded. The bearings are no longer acces-sible once installed, and so maintenance-free bearings are required.Isolating valves act as safety switches: if the pressure is too high, the isolating valve opens. If a section of the pipeline is leaking, the isolating valve closes.

Bearing with KS PERMAGLIDE® P10/P11 plain bearing bushesThe shaft journal and the valve disc are mounted with KS PERMAGLIDE® P10 or P11 plain bearing bushes. The P10 and P11 plain bearings do not be-come electrostatically charged, as they act as electrical conductors after running-in. The isolating valves can also be used in environ-ments where there are explosive gases.

1.3 Bearing of the piston rod in pneumatic cylindersSector: Conveyor technology, automation technology, drive engineering, engineering, handling technology, compressed-air technology

Product usedKS PERMAGLIDE® cylindrical plain bearingbush, design PAP … P10

Function Pneumatic cylinders are used for the drive of linear movements, e.g. in conveyor technology and in engineering. Pneumatic cylinders are either single-acting or double-acting. The force of the piston rod thus acts in one or in both directions on the axle. This means that the cylinder can be used to generate a pushing force or a pulling force. The use of compressed air can lead to jerky movements and vibrations.

Bearing with KS PERMAGLIDE® P20 plain bearingsIn pneumatic cylinders, KS PERMAGLIDE® P20 plain bearing bushes are used as spigot bearings for the piston rod. The plain bearings are sealed and initially lubricated with grease.

The plain bearings are designed with oil distributing pockets in the sliding surface. This guarantees the appropriate distribution of lubricant over the entire service life. Lubrication ensures a low and constant friction coefficient and enables smooth linear movement. The bearing also provides a high level of guidance accuracy under changing operating conditions. The structure of the P20 makes it ideally suited to this application. High lateral forces, significant vibrations and sometimes high speeds act on the bearing position.

With its extreme stress potential and distinct damping characteristic, the P20 constantly maintains its function as a precise spigot bearing.

Advantage: Reliable bearing with KS PERMAGLIDE® P20 plain bearings • Low-maintenance operation with

lubrication• High wear resistance• Constant and low friction coefficient• Good damping characteristics• Insensitivity to shocks and impacts

Description of materialKS PERMAGLIDE® P20 is a low-maintenance, leaded bearing material with a high performance. It is designed for grease-lubricated or liquid-lubricated applications. This composite, multi-layered material excels through its high rigidity, durability and resistance to oscillation and vibration. These characteristics are largely achieved by a sliding layer system made of polyvinylidenfluoride (PVDF), polytetra-fluoroethylene (PTFE) and lead. The wear-resistant material has already proven itself many times in industry.

The standard P20 version features oil distributing pockets as per DIN ISO 3547. The bearings are provided ready to install for recommended connection-design installation dimensions. Also available are versions with a different wall thickness, suitable for rework when installed, or with a smooth sliding surface for hydrodynamic applications.

FunctionGear pumps are used in many applications to deliver liquids (media) or as a force- transmitting drive for hydraulic motors.The gear pump delivers the medium evenly from the intake side (intake), through the gears and to the thrust side (exhaust). Among other applications, gear pumps are used in vehicles as a fuel pump, oil pump or coolant pump. The chemical industry uses gear pumps to deliver organic and inorganic chemicals. Within construction machinery and agricultural machinery, gear pumps are used as a drive for hydraulic motors, for example.

Bearing with KS PERMAGLIDE® P10 plain bearing bushesKS PERMAGLIDE® P10 plain bearings are used as the main bearing for the gear shafts in gear pumps. A low operating bearing clearance is essen-tial for the high build-up of pressure and for low gear-pump leakage. To ensure a fault-free hydrodynamic operating state, the plain bearings must exhibit a bearing clear-ance tailored to the operating medium. The plain bearings come into direct contact with the operating medium. Aggressive media may be used, depending on the applica-tion. The plain bearings must therefore offer high resistance to abrasion, good resist-ance to erosion, chemical compatibility and low swelling tendency.

KS PERMAGLIDE® P10 plain bearings meet these requirements. The excellent dry- running behaviour of KS PERMAGLIDE® P10 plain bearings also ensures a low level of wear in the mixed friction operation that occurs when the pump is switched on and off.

Technical data for the application applied• Application: Central lubrication with

stationary combustion engines• Displacement:

Up to 1400 cc/rev• Engine speed: 2,000 to 2,500 rpm• pmax: 25 bar• Flow: up to 1,600 l/min

In damp environments in particular, this sliding layer system provides outstanding protection against corrosion. Moreover, lead and PTFE have an extremely low absorption tendency. Absorption of the surrounding fluids, swelling of the ma-terials and chemical damage to interacting sliding partners are prevented. The result is dimensional stability and optimum corro-sion protection during use.

Product used KS PERMAGLIDE® cylindrical plain bearing bush, design PAP … P10

FunctionMost wind turbine systems have a horizontally-mounted 3-blade rotor. The wind causes the rotor blades to rotate. The mechanical rotary motion is transferred from the rotor hub to the rotor shaft. The low speeds of the rotor are converted at

a ratio of 1:25 by a gearbox for generator operation. The rotor shaft is installed in the hollow shaft of the gearbox in the input stage. The rotor shaft and hollow shaft are connected on one side and rotate synchronously. The rotor shaft twists as a result of the strong alternating stresses. This leads to micro-movements on the guide parts. Such strained contact points are usually subject to tribo-chemical corrosion.

Bearing with KS PERMAGLIDE® P10 plain bearing bushesWith a maintenance-free KS PERMAGLIDE® P10 plain bearing, tribo-chemical corrosion is prevented and the guide quality of the bearing position is improved. The negative impact from stick-slip is minimised thanks to the low friction coefficient of KS PERMAGLIDE® P10 plain bearings.

KS PERMAGLIDE® P10 plain bearings are used as spigot bearings for the rotor shaft in the gearbox of wind turbine systems


1.5 Gearbox rotor shaft in wind turbine systemsSector: power engineering


Alternative designations for wind turbine systems• Wind turbine• Wind energy plant• Wind energy converter• Wind power station

Advantage: reliable function of the bearing with KS PERMAGLIDE® P10 plain bearings• Maintenance-free • Protected from tribo-chemical corrosion• Low operating bearing clearance• Low level of wear, even with alternating

stresses• Low friction coefficient

Description of materialKS PERMAGLIDE® P10 is a universal plain bearing material for both dry and lubricated applications. The composite, multi-layered material excels thanks to its high rigidity, durability, high chemical resistance and good emer-gency running properties. These character-istics are achieved to a great extent through the use of lead bronze sintered onto a steel base, and friction-lowering additives of fluoropolymer PTFE and the metal lead.



Blade adjustment unit bearing with KS PERMAGLIDE® P20 plain bearings



FunctionMost wind turbine systems have a horizontally-mounted 3-blade rotor. The wind causes the rotor blades to rotate. The mechanical rotary motion is transferred from the rotor hub to the rotor shaft and

is converted by the gearbox for generator operation. In order to take full advantage of the wind, the nacelle and rotor blades are continually adjusted. The rotor blades are mounted in the hub so that they are rotatable and are adjusted hydraulically using a push rod. The push rod must not be bent and must be guided using damping because of permanent vibrations.

Bearing with KS PERMAGLIDE® P20 plain bearing bushesThe linear spigot bearing of the push rod is realised using two low-maintenance KS PERMAGLIDE® P20 plain bearings. The plain bearings are initially lubricated with grease, which ensures low adjusting forces and smooth guiding. Thanks to the high wear resistance of the KS PERMAGLIDE® P20 material, the bearing clearance hardly changes, meaning precise adjustment is constantly guaranteed.

Product usedKS PERMAGLIDE® cylindrical plain bearing bushing, type PAP … P14

Bearing of feed shafts and rollers with KS PERMAGLIDE® P14 plain bearing bushesFranking and inserting require a great num-ber of precise movements, e.g. the addition and removal of envelopes and paper as well as paper folding. The bearing positions are mostly subject to an oscillating movement. Cylindrical plain bearing bushes made from unleaded KS PERMAGLIDE® P14 are used for transport shafts and rollers, for example.

The material is highly suitable for bearings due to its low wear and low operating bear-ing clearance.Due to weight and installation space, the sintered bronze bushes previously used in the application have been almost com-pletely replaced by slim KS PERMAGLIDE® plain bearing bushes. The all-plastic plain bearings previously used by a manufacturer are too easily worn and do not guarantee sufficient protection against fractures.

Franking machine application

Needle bearings can also be replaced by KS PERMAGLIDE® plain bearing bushes for these applications. KS PERMAGLIDE® plain bearing bushes are economical and take up very little space compared with needle bearings.

FunctionPile-driving and drilling machines must function reliably.When used outdoors on building sites, the swivelling joints of the leaders and the bearing positions on the swivelling joints are subjected to harsh conditions, such as high temperature fluctuations, moisture and dirt. When pile-driving, impacts and shocks subject the bearing position to stress.

Bearing with KS PERMAGLIDE® P20 plain bearing bushes and P20 thrust washersIn the realised application, the pins of the swivel joint bearing run in two KS PERMAGLIDE® P20 plain bearing bushes.

Pile-driving and drilling machine KS PERMAGLIDE® P20 plain bearing bush and P20 thrust washer

Products usedKS PERMAGLIDE® cylindrical plain bearing bush, design PAP … P20KS PERMAGLIDE® thrust washers, design PAW … P20

Two KS PERMAGLIDE® P20 thrust washers sit between the arms of the joint.The plain bearings compensate for misalignments in the roughly welded joints. The polymer sliding layer of the material KS PERMAGLIDE® P20 is insensitive to high edge loading.When used with a grease lubricant, the plastic in this application has good damping performance when subjected to vibrations and impacts. This means that the impacts are diminished by the time they reach the hydraulic excavator. By using the KS PERMAGLIDE® P20 plain bearings, the bearing functions reliably despite the difficult operating conditions.

Advantages of KS PERMAGLIDE® P20 plain bearings• Insensitivity to shocks and impacts• Low sensitivity to edge loading• Good damping characteristics• High wear resistance• Insensitivity to dirt• Insensitivity to moisture due to low

swelling tendency• Operating temperature range

of –40 °C to 110 °C• Low-maintenance operation with

lubrication

1.8 Bearing in pile-driving and drilling machinesSector: Construction machines, civil engineering



Description of materialKS PERMAGLIDE® P20 is a low-maintenance, high-performance leaded bearing material. The material is designed for grease-lubricated or liquid-lubricated applications. This composite, multi-layered material excels thanks to its high rigidity, durability and resistance to oscillation and vibration. These characteristics are largely achieved by a sliding layer system made of polyvinylidene fluoride (PVDF), polytetrafluoroethylene (PTFE) and lead. The wear-resistant material has already proven itself many times in industry. The standard P20 version features oil distributing pockets as per DIN ISO 3547. The bearings are provided ready to install for recommended connection-design installation dimensions. Also available are versions with a different wall thickness, suitable for rework when installed, or with a smooth sliding surface for hydrodynamic applications.

Application descriptionTubes, posts or guide rails are driven into the ground using pile-driving machines. Drilling machines are used for drilling bores in specialist civil engineering, tunnelling, canal construction and for drilling water wells or geothermal wells.In combined pile-driving and drilling systems, either a hydraulic hammer or a boring machine is mounted on a telescopic leader. The leader is attached to the outrigger of the hydraulic excavator. The hydraulic hammer or boring machine runs up and down the leader. The link piece between the leader and excavator takes the form of an articulated bearing. The leader is straightened laterally by free swivelling motions in this way.

Description of the joint bearingJoint bearings are articulated bearing elements based on plain bearings. Joint bearings allow swivelling motions, rotary motions and tilting motions and transfer static and dynamic forces. Maintenance-free joint bearings or joint bearings that can be re-lubricated are used depending on the application.

Function Concrete placing booms can be extended in different ways depending on the operating conditions. When used outdoors on building sites, the articulated joints and their bearing positions are subjected to harsh conditions. Constant temperature fluctuations, moisture, dirt and chemically aggressive concrete or cement dust all influence the durability of the bearing positions. The booms must always function reliably. The bearing positions must therefore be robust, wear-resistant and always have a high freedom of movement in every boom configuration. Signs of corrosion after longer downtime periods must not lead to the articulated joints becoming stuck. The bearings must slide smoothly to place the concrete exactly, even when subjected to minor swivelling motions. The bearings must not fail prematurely due to abrasive sand or cement particles.

Bearing of the articulated joints with KS PERMAGLIDE® P11 plain bearing bushesIn the realised application, the bearing positions of the articulated joints have been equipped with KS PERMAGLIDE® P11 plain bearing bushes. Thanks to its bronze structure, the material KS PERMAGLIDE® P11 is very corrosion-resistant and has good embedding ability thanks to the polymer solid lubricant.

Betonverteilermast

KS PERMAGLIDE® P11 is intended as a maintenance-free plain bearing material for dry running. The bearing position should nevertheless still be regularly inspected due to the difficult operating conditions of this application. The bearing position has also been sealed with grease to ensure that no dirt can infiltrate it. In addition, this grease protects the pins of the joints from corrosion, and squeezing out the grease cleans the bearings. KS PERMAGLIDE® P11 plain bearing bushes are robust and reliable in operation with a minimum of sealing effort – and under harsh conditions. These properties make KS PERMAGLIDE® P11 plain bearing bushes ideally suited for bearing the articulated joints in concrete placing booms.

Advantages of KS PERMAGLIDE® P11 plain bearings• Maintenance-free• Low wear• No additional corrosion protection

required• High chemical resistance, especially

suitable for use in aggressive media• Temperature range –200 °C to +280 °C• Largely resistant to swelling• Does not absorb water• Almost no stick-slip effect• Constantly low friction value

1.9 Articulated joints of concrete placing boomsSector: Construction machines



Description of materialKS PERMAGLIDE® P11 is a leaded, robust bearing material that has the highest levels of tribological performance. The material is designed for maintenance-free, dry-running applications, but can also be used in systems with liquid lubrication.

The material P11 is recommended for more stringent requirements in terms of corrosion resistance or for use in aggressive media. In comparison to composite materials using plastic and steel, the material has the following advantages:• Very good thermal conductivity and

therefore also increased operational safety for fast-running systems

• Not ferromagnetic• Higher corrosion resistance thanks

to bronze backing

Application descriptionConcrete placing booms are booms that are attached to utility vehicles or special columns, and that have pipelines through which concrete is pumped. Using one or more articulated joints, the booms can be folded up to be more compact or raised and aligned precisely. After use, the boom is cleaned with water and folded up completely.

Additional designations for concrete placing booms• Truck-mounted concrete pump• Truck mixer concrete pump• Long-reach boom pump• In addition to these, separate placing

booms are used in combination with stationary concrete pumps.



KS PERMAGLIDE® P14 plain bearing bushMatrix printer application


Bearing of the ink ribbon drive in matrix printers with KS PERMAGLIDE® P14 plain bearing bushesIf duplicates are required, e.g. for prescriptions at a medical practice or for delivery notes in logistics, matrix printers are still used.

Here, the ribbon is generally transported via a gear. The compact design of the printer requires miniature plain bearings with low space requirements. Lubrication has not been used in the application that was implemented as paper dust and grease can combine to form a paste. The friction value would therefore be disrupted and consequently, there would be a negative impact on the drive motor.

With dry running, however, it was possible to make the motor smaller. In this application, the previously used sintered bearings were replaced by KS PERMAGLIDE® P14 plain bearings, meaning the manufacturing costs could be reduced even further.KS PERMAGLIDE® P14 plain bearings are also suitable for transporting the ink ribbon in heavy-duty laser printers and inkjet printers.

Reliable bearing function with KS PERMAGLIDE® P14 plain bearings as a result of the following advantages:• Unleaded• Compliant with Directive 2011/65/EU

(RoHS II)• Compact size• Maintenance-free operation under dry-

running conditions • Low wear

• Very low stick-slip tendency• Low friction value• Rotating or oscillating movements up to

a speed of 1 m/s• Temperature range -200°C to 280°C

Description of material P14KS PERMAGLIDE® P14 is an unleaded standard sliding material with a high tribological performance. It is designed for maintenance-free applications under dry-running conditions. It may also be employed in systems with liquid lubrication, however.The use of grease as a lubricant in contact with P14 is only possible to a limited extent, and is not recommended.

FunctionPotato harvesters dig up potatoes with ploughshares, separate the leaves and clean the potatoes. Some machines have integrated reservoirs.Potato harvesters with their own drive have hydraulic steering. The steering pivots of the machines swivel 90 °. The steering pivots are subjected to high weights of up to 15 t. Due to the uneven terrain, the steering pivots are subjected to stress from knocks and impacts. The plain bearings in the steering pivots therefore face high impact loads and edge loads.

Bearing with KS PERMAGLIDE® P20 plain bearing bushes and thrust washers The bearing positions are subjected to harsh conditions, such as temperature fluctuations, dirt and moisture. During harvest time, the machines are in constant use and must work reliably at all times without maintenance. Signs of corrosion after longer downtime periods must not lead to the bearing becoming stuck.

Using the KS PERMAGLIDE® P20 plain bearing bushes and P20 thrust washers means that the bearing functions reliably despite the difficult operating conditions. The thick plastic sliding layer over the sintered bronze dampens knocks and impacts. The wear resistance of the KS PERMAGLIDE® P20 plain bearings ensures that the steering pivots have a long service life. The bearings retain their good sliding properties even with inadequate lubrication due to lack of maintenance.

FunctionThe steering system of a tractor is connected to the steering levers on the wheel via the steering linkage. A ball joint in the tie rod carries out the force transmission with spring suspension.

The bearings of the ball joint are constantly subjected to the influences of dirt, moisture, temperature fluctuations and vibrations with heavy impacts under extremely harsh operating conditions.No play may occur in the ball joint over the entire service life. The ball joint should be maintenance-free over the entire service life.

Bearing with KS PERMAGLIDE® plain bearing spherical shell design PAX … P20The bearing with KS PERMAGLIDE® plain bearing spherical shells design PAX … P20 fulfils these requirements and guarantees precise guidance over the long-term despite all these influences.

FunctionThe fifth-wheel coupling connects the trailer of a semitrailer with the towing vehicle with a secure but rotatable connection. When the towing vehicle is moving in reverse, the kingpin of the trailer is pushed into the coupling. A locking mechanism locks the fifth-wheel coupling automatically. It is now in travelling position. A breech wedge se-cures the kingpin. To uncouple, the locking mechanism is released with a hand lever. During the release action, the locking me-chanism parts move into retraction positi-on. The towing vehicle is uncoupled from the trailer.

FunctionClose coupling systems are used between the trailer and towing vehicle on semitrai-lers. The distance between the trailer and towing vehicle is extremely small during for-wards travel. The close coupling moves the trailer away from the towing vehicle by 500 mm in curves. The advantage over normal coupling systems is the longer loading area with the same total length.

The bridge is twisted in relation to the trai-ler in curves. The twisting of the bridge is transferred to the ring gear. The ring gear engages in a ring gear ring on the crank disc. The connecting rod is fastened with bearings on the trailer and on the crank disc. This means that the crank mechanism is adjusted in every curve. The trailer is moved backwards on linear guides.

Bearing with KS PERMAGLIDE® P20 plain bearing bushes and thrust washers In the specified application, KS PERMAGLIDE® P20 plain bearing bushes are used for the linear guide. There are two rigid shafts running on the trailer in two KS PERMAGLIDE® P20 plain bearing units each. The plain bearing bushes are pressed into the connecting rod. KS PERMAGLIDE® P20 thrust washers are used for the axial bearing.

Using the KS PERMAGLIDE® P20 plain bea-ring bushes and thrust washers means that the close coupling also functions reliably under difficult conditions:• High wear resistance• Highly stressable• Insensitive to shocks and impacts• Insensitive to dirt and moisture• No tribocorrosion• Smooth running• Good damping characteristics• Low-maintenance operation with

FunctionTo reach the engine under the cab for main-tenance work on utility vehicles, the driver‘s cab is tilted forwards. The pivoted joint on the driver‘s cab is fitted with two plain bearings for the swivel movement.

The pivoted joint must always work smooth-ly, even if it is not used frequently. The pivoted joint is constantly subjected to shocks and vibrations during travel. This means that there is a risk of tribocorrosion on the plain bearings.

KS PERMAGLIDE® P20 plain bearing bushes were installed in the application. Using the KS PERMAGLIDE® plain bearing bushes means that no tribocorrosion occurs.

A plain bearing is positioned on each side of the swivel axis. The plain bearing bushes were pressed into a needle bush for easy mounting. The plain bearings were lubricated prior to installation. The lubrication is sufficient for the entire service life. The sliding speed and temperature are negligible in this ap-plication.

Turbine Hoover Dam


FunctionIn storage power stations, water is pumped into higher-lying storage reservoirs using cheap night-time electricity. At energy demand peaks, the water is allowed to flow back down to drive a turbine. In the process, the turbine drives a generator to produce electricity. In order to set the op-timum operating point in the pump as well as in the turbine operation, swivel-mounted stator blades are fitted between the ring channel and impeller.

Bearing with KS PERMAGLIDE® P11 plain bearing bushesThe bearing for the stator blades are manu-factured with maintenance-free plain bea-ring bushes made from KS PERMAGLIDE® P11. This has eliminated the need for additional lubricant. High static compressions arising from the flowing medium permanently af-fect the bearing. In addition, there are high-frequency vibrations. The plain bearing has direct contact with the water. The material with bronze backing and PTFE sliding layer does not display any signs of corrosion. Similarly, tribocorrosion does not occur because the sliding metals are separated by the layer of PTFE. KS PERMAGLIDE® P11 does not absorb any water, allowing the

plain bearing to maintain its dimensions. Moreover, the high wear resistance always provides a constant operating bearing clearance, which would otherwise have a negative influence on the efficiency of the pump or turbine. The service life of bearings made of KS PERMAGLIDE® P11 is thus ex-ceptionally long, with costly maintenance intervals being reduced.

Product usedKS PERMAGLIDE® plain bearing strips, design PAS … P11

FunctionMovable tables are used for equipping hydraulic presses. They enable the machine to be loaded and unloaded quickly. The mo-vable table consists of a workpiece holder mounted on a table. For loading, the table is pulled out and pushed back into the ma-chine with the workpiece once mounted.

Requirements for the bearings in movable tables• A slight plain bearing clearance is required

in order to guide the work table precisely and without canting. The slight plain bea-ring clearance means that a large portion of the stress from the pressing process is transferred to the frame via the plain bearings.

• In order to pull it out and push it in easily, the table must run smoothly in the guide for the long-term.

• The machine must withstand long periods of use with low maintenance requirements.

• To prevent the table from becoming too big, plain bearings with small dimensions are required.

• The costs for production and mounting should be as low as possible.

Bearing with KS PERMAGLIDE® P11 plain bearing stripsThe bearings on the movable workpiece ta-ble of the press have been made with mul-tiple maintenance-free plain bearing strips in the material KS PERMAGLIDE® P11. The strips were screwed into the recess of the table frame. This ensures that the table is guided by the P11 strips at the side, above and below the table.

Advantages of the KS PERMAGLIDE® P11 plain bearing strips for use in movable tables• Maintenance-free• No hardened interacting sliding surface

required – providing simple design, low-cost production and mounting of the guide

• Low wear• Practically constant operating bearing

The-se characteristics are largely achieved by a sliding layer system made of polyvinylidene fluoride (PVDF), polytetrafluoroethylene (PTFE) and lead. The wear-resistant material has already proven itself many times in industry. The standard P20 version features oil distributing pockets as per DIN ISO 3547. The bearings are provided ready to install for recommended connection-design installation dimensions. Also available are versions with a different wall thickness, suitable for rework when installed, or with a smooth sliding surface for hydrodynamic applications.
