The “D” of this symbol stands for “Daido Metal Company.”

It also stands for “Development,”

“Dream”and“Dynamic.”

The design also includes the “I”of“Innovation,”

“Invention”and“Intellectual excitement.”

The shape represents “bimetal”and “half bearing”

and the curve is also an allusion to a bridge.

The blue color is the blue of the sky and the sea, meaning the Earth.

"Tribology"- the word is derived from the Greek "tribos" meaning "friction" and refers to the basic

technology of bearings: the physical and scientific analysis of friction, wear and lubrication when

physical objects move. Machines always have parts that are subject to friction, making them

susceptible to wear and other problems. In order to provide solutions to these problems Daido

Metal established a tribological approach using a combination of bimetal, surface treatment and

precision machining technologies. We now have a global reputation as a manufacturer of plain

bearings for all fields with a strong focus on the automotive industry. The knowledge of bearings

we have fostered has opened up new fields and is expanding the dreams and possibilities for

21st century society. Where there are moving parts you will find Daido products. Our aim is to

build on our position as Japan's leader in Tribology to become the World's leader in Tribology.

Meeting the Challenges of Ecology Through TechnologyDaido Metal is also actively undertaking the development of ecological products that are not harmful to people or the environment.The restriction on products containing materials such as lead, hexavalent chromium and other chemical substances that have an adverse impact on humans and the eco system on a global scale are becoming stricter as shown in the Restriction on Hazardous Substances (RoHS) and End-of-Life Vehicles (ELV) directives. As a company dealing with all types of bearings, from development through to scrapping, we rigorously control the chemical substances in our products and approach this issue with stress on completely eliminating such substances from use.

Disposition of polytetrafluoroethylene (PTFE) bearings with backsteel

When specifying PTFE bearings with backsteel for new designs please select a substitute material. For previously designed products please switch from affected materials to a substitute material as soon as possible.

We have been manufacturing and selling PTFE bearings with backsteel for more than thirty years but environmental issues have made it difficult to offer some types of PTFE bearings with backsteel.

Instead of using lead which is the predominant bearing material, we are developing lead-free materials whose properties are equivalent to those of lead. We are doing this out of concern for the impact of lead on the environment. This is demonstrated in fields such as bearings for automotive use and bearings for dam gates where high ecological performance is a concern.

Products bearing this mark contain levels of cadmium, lead, mercury and hexavalent chromium that are within the restrictions of the ELV Directive.

Products bearing this mark contain levels of cadmium, lead, mercury, hexavalent chromium, polybrominated biphenyls (PBB) and polybrominated diphenyl ether (PBDE) that are all within the restrictions of the RoHS Directive.

Cementing our Reputation as the Leading Company for BearingsComprehensive Tribology Research and Development

Quality Assurance Recognized Worldwide

Permanent Environmental Management System

Daido Metal has Tribology in its genes. Accordingly, we have established a central research laboratory that is one of the few comprehensive Tribology research and development bodies in the world. It deals with everything from theoretical research to development of new materials and composite materials, development and design of bearing products, and development of production technology. Its scope extends as far as the development of products that utilize technology relating to Tribology. By linking from the central research laboratory to the devel-opment teams in each production department, we can respond accurately to sophisticated requirements. Through joint development and technology exchange with our clients, who are world leaders in their fields, we can also make a contribution to improving the standard of technology. We are also contributing to international standardization through our participation in the "ISO/TC123 Japan Plain Bearing Committee" of the Japan Society of Mechanical Engineers.

Daido Metal is promoting production activity based on supplying products to the user from our nearest production location. This is done through our global management system. In doing so we are able to not only acquire international quality standards such as ISO9001 and ISO/TS16949, but also to meet specific customer requirements and certification such as Ford Q1.

Daido Metal considers the global environment to be mankind's common asset. We actively work to protect the environment as it is an important issue. We perceive environmental management systems such as ISO 14001 as an effective tool to continuously reduce our impact on the envir-onment.

Centrifugal Casting Manufacturing

Process This is the technology for making cylindrical bearings of uniform strength, with no joints. The bear-ing alloy is cast by utilizing the centrifugal force generated by ro-tating a steel pipe. All processes are integrated, from working to fin-ishing.

By scattering copper alloy powder onto steel and then heating to a high temperature, a diffused bonding is created.

Centrifugal Casting

Bimetal Manufacturing Process

A "bimetal" is a compound material that consists of a bearing layer strongly bonded onto a steel sub-strate, which gives it strength and di-mensional stability. We make use of a variety of bonding technologies matched to the characteristics of dif-ferent bearing materials.

DDK05 bearing is free from the skew problem.

DDK05 bearing can also be used for sliding motion in the axial

direction.

DDK05 bearing allows very compact equipment design that

does not occupy wide space.

In general the bearing price is competitive compared to ball

bearings.

The bearing exhibits preeminent resistance against fretting

corrosion.

Major Superior Points to Roller Bearing

Permitted bearing pressure is high.

The roller bearing cannot be used under the conditions of high-

load, low speed operation, reciprocating and intermittent motion

where boundary lubrication condition cannot be assured and

further at high temperature (+280℃) or low temperature (-200℃).

DDK05 bearing can be used in various liquids and gases, or in a

vacuum.

Standard bearings are stocked and are available for quick

delivery.

Friction properties/characteristics of DDK05 Dry Bearing

The graph shows that during the running in stage, part of the

surface layer rapidly transfers to the shaft surface to make to the

irregularity flat and form a smooth low-wear and low-friction

surface. During operation when the surface layer consisting of

PTFE mixture becomes thinner friction between the metals of the

bearing and the shaft temporarily occurs. Then the PTFE mixture

expands due to the heat generated by the friction and the mixture is

pushed out from the porous intermediate layer and supplied to the

bearing surface very slowly. Therefore no wear occurs on the shaft.

some hours of running in have

elapsed.

Before running-in

Proper Operation of DDK05 Dry Bearing

When the DDK05 bearing is operated under conditions of high

loading, the appearance of the bearing surface changes as the

running-in process occurs. When the running in process is

complete the bearing surface changes to gray-green colour.

However this shows that the DDK05 bearing has been run in and is

operating normally. This change in appearance does not affect the

bearing performance and can withstand extended operation.

This product is an environmentally friendly "lead-free bearing." The material structure of DAIDYNE DDK02 consists of multiple layers of PTFE resin + porous intermediate layer + steel lining (similar to that of DDK05 Dry Bearing) and due to the improvement of the sliding layer and porous layer, boundary surface performance and fluid lubrication have also improved.

Features

Excellent wear resistance due to the performance of the

boundary surface and fluid lubrication. Wear resistance is two or

three times better than that of DDK05.

Excellent load resistance due to the performance of the

boundary surface and fluid lubrication. Load resistance two or

three times more than that of DDK05.

Low friction characteristics due to the performance of boundary

surface and fluid lubrication. Lower friction characteristics than

that of DDK05

Excellent cavitation resistance compared with DDK05

As this is a pre-lubricating bearing ensure it is filled with lubricant before installation. Then supply a small amount of lubricant at predetermined intervals to allow the bearing to withstand long term operation. The bearing has a structure where bronze in a spherical powdered form is sintered on to the steel backing. Polyacetal resin is then impregnated into the surface.

Operation is quiet, free from squeaking or knocking.

Low friction characteristic prevents damage to the shaft (mating

surface).

The bearing surface remains virtually wear-free with minimum

amount of lubricant (grease or oil).

Low starting friction permits very smooth rotation at fire up and

at low speed under high load conditions. Sliding surfaces are

also seizure free.

Shaft misalignment tolerance is excellent.

The bearing can withstand impact loads.

Excellent load-carrying performance is maintained even under

oscillating and fretting conditions.

1.Load Carrying

CapabilityThe capability varies de-

pending on the load prop-

erties and lubrication con-

ditions. The maximum

load that DBX01 can carry

is shown in Table 1.

2.Relation between

Wear and the interval

of lubricationOil is supplied to DBX01

bearings at assembly. The

amount of wear after run-

ning in is very small and

there is virtually none to

be seen. Furthermore,

wear is kept to a minimum

until the lubricant is ex-

hausted (Figure 1).

3.PV Value and Bearing performanceThe performance of bearing is influenced by the PV

value and the operating conditions.

The PV value is the product of Specific Load (MPa) and

sliding speed (m/min). The solid line "A" in Figure 2

shows the bearing life when grease was supplied only at

installation, and the dashed line "B" shows the

recommended grease re-supply interval.

When the PV value exceeds 170 MPa-m/min,

successive oil lubrication is desired.

Features

The wide range of adjustment from micro clearance to negative

clearance eliminates rattling inside the assembly.

A resin layer consisting mostly of PTFE provides smooth opera-

tion with stable friction.

Compound material of metal mesh and resin offers excellent

load, wear and corrosion resistance.

This material is applicable to a wide range of service tempera-

tures (-200～+280℃).

Wear does not occur on products made of this material so is ap-

plicable for non-lubricant operations.

Due to thin and flexible wall the material is space saving and

enables easy installation.

Installation by adhesion is possible.

Example of Typical Forming Physical Characteristics

Shaft

This material can be cut to any figure and formed to any shape.

・ Process the bottom end of the shaft as shown in the diagram

below to avoid damage at the time of installation.

Adhesion

DAIMESH DMM01 can be installed by adhesion. This method is ef-

fective especially for the installation of flat bar figure and hemispheri-

cal cup figure.

・ It is important to pre-clean both the DAIMESH DMM and the surface

to which it will be adhered. Select an appropriate adhesive for

accurate adhesion.

・ Please consult us for more information on adhesion.

・ Ensure the shaft roughness is set at 3.2s. For more stable

operational use ensure that shaft roughness is set to 1.6s.

Installation procedure

The dimensions of DAIMESH DMM01 can be set as either clear-

ance or negative clearance. Select one of these two installation

methods by taking into consideration the balance of rattling and

service torque.

・ Clearance methodInstall the bearing and then assemble the shaft. The torque chan-

ges corresponding to surface load and surface speed.

・ Negative clearance methodThis method should be selected to eliminate rattling. Bearing and

shaft can be installed together in the housing. Torque is related to

the negative clearance condition.

・ Calculation of shaft dimensions (ensure to take max and min values of each dimension into consideration)(1) Clearance method

Shaft diameter = Inner diameter of housing - (2 x thickness of

bushing) - clearance

(2) Clamping allowance method

Shaft diameter = Inner diameter of housing - (2 x thickness of

bushing) + negative clearance

THERMALLOY is an oilless metal bearing into whose base metal a fine solid lubricant (usually consisting of carbon) is uniformly dispersed. THERMALLOY is supplied as an optimum bearing due to its design, and the selected combinations of base metal, solid lubricant and grain size which enable it to accommodate a wide range of operating conditions.

56

Features Types

Can be used from extremely high temperatures to low

temperatures

(-200℃ to +700℃ depending on type of material)

Strong against mixed hard foreign particles

Can withstand high-speed operation in water and in seawater

Can withstand strong corrosive atmospheres

Although the bearing is designed as a dry bearing, when oil and

grease are both provided its performance exceeds that of

lubricated bearings.

The material is strong enough to withstand high loads.

The bearing adapts to the shaft smoothly from the beginning of

operation and the slip stick phenomenon is prevented.

Seizure is prevented and the surface of engaging component is

not damaged.

Can be machined to special shapes

Can be used in a vacuum

The material is a good conductor of heat and electricity,

therefore heat is not accumulated in the bearing.

The solid material allows sliding on multiple surfaces at the

same time.

Compliant with the Dam Facility Technical Standards

(Proposed) as a dispersed solid-lubricant type product.

Hardness of Mating Surface

The above mentioned bearing pressure is the value given at normal clearance. If the bearing is used with extremely large clearance, ap-

ply a lower bearing pressure.

The relationship between the bearing pressure and allowable sliding speed is decided through a balance of heat generation and heat radi-

ation in the bearing.

The amount of wear is affected by bearing pressure, sliding speed and the roughness of the shaft.

The values given for maximum bearing pressure and maximum

sliding speed are merely for guidance, and may vary dependant

on other conditions. In addition, usage of the bearing at both

maximum bearing pressure and maximum sliding speed is likely

to cause heat generation and wear.

Special material is prepared for use in a vacuum. Please consult

us for more information.For usage below 200℃ the W symbol is required only on lead-

bronze alloy or bronze alloy materials.

Used for bearings for atomic en-ergy related and anti-radiation use. Has good corrosion resis-tance and operation in liquid is preferable.

High temperature properties are good, strength is excellent.

High temperature and corrosion resistance properties are excellent.

Important Notes on the Determination of Material Codes

Each material code is composed of symbols that indicate the

alloy series, the amount of graphite contained, and the state of

graphite dispersal. When you have determined the material code

from the upper table, we add a manufacturing-based

classification code and indicate it on the label for the actual

article and in the drawings.

Examples

Your selected code plus our added classification code.

30/8 -> 30/8-2Mo

Meaning of the code

In this example, "30/" is the alloy series, "8"is the percentage of

powdered graphite, and "2Mo" is a code we add.

144SB12PW -> 144SB12P-2MoW

In this example, "144SBW" is the alloy series, "12P"is the

percentage of powdered graphite, and "2Mo" is a code we add.

The amount of graphite contained is normally 6%, 8%, 10%, or

12%.

A powdered-graphite value of 8% and a granulated-graphite

value of 12% (indicated by a "P" code) are nearly equivalent in

terms of strength, and have an identical maximum specific load.

Powdered graphite is effective in situations where contamination

by external foreign matter does not occur, and granulated

graphite is effective in situations susceptible to contamination by

sand, iron filings, or the like.

・

・

・

For powdered graphite and lead-bronze, bronze, and special bronze alloys of B40 up to B120, values of up to 84l are possible.For other than the above, values are up to 64l.For granulated graphite, values are up to 64l for all dies.

For plate material (powdered graphite) and lead-bronze, bronze, and special bronze alloys, values of up to 34T are possible.

For powdered graphite and lead-bronze, bronze, and special bronze alloys other than R40, R50, R60B, or R70, values of up to 84l are possible.For other than the above, values are up to 64l.For granulated graphite, values are up to 64l for all dies.For other than the above, values are up to 64l.For granulated graphite, values are up to 64l for all dies.

Designing Conditions

Service Life

・The "W," "N" and "W-N" values are measured in the air at an

ordinary temperature without a lubricant supply.

・When using the unit at temperatures above 100℃ as a guide the

"N" and "W-N" values should be half of that of the service range.

・When the unit is used with a lubricant, a smaller load, at lower

speed, operated intermittently or for a shorter time it may be

used above the service range. Please consult us.

・When the unit is to be used out of the specified service range or

in a special atmosphere (in a vacuum, gas or chemical solution),

it may be made from other materials. Please consult us.

・Bearing boxes made of gray cast iron (FC) are also available.

The service life of the THERMALLOY pillow unit is generally

determined by the wear to the inside diameter of the

THERMALLOY. The wear greatly depends on the conditions of use.

In other words it is affected by many factors including load, rotating

speed, temperature, lubrication status, atmosphere and intrusion of

foreign particles, so it is very difficult to calculate with a formula.

Use the test data shown on the right as a reference when designing

the THERMALLOY pillow unit.

The wear depth per 1 km of friction distance ata specific load of 2MPa [20kg/cm2], a speed of3m/min and a temperature of 150°C without a lubricant supply can be approximated as follows:Wear depth / friction distance = 2μm/km×1.5　　　　　　　　　　　　 = 3μm/km

〈Characteristics of DAISLIDE HA〉Solid bearing for medium to high loads

Maintenance-free, no need to supply oil

Excellent wear resistance properties. Excellent wear resistance

properties are exhibited in applications where oil film formation is

difficult such as reciprocating, intermittent or oscillating motions

under conditions of high load and low speed.

Friction coefficient is low.

Can be used at a range of temperatures

Free design is possible on the shape and the size.

Excellent corrosion and chemical resistance. This bearing can

be used in river or sea water, in special liquids where chemical

resistance of the metal base and solid lubricant is needed, and

in gas where oil supply is difficult.

Excellent impact resistance

Features

In an acid or alkaline atmosphere properties may differ depending on the

type, density and humidity. Please do a sample test or consult us.（）

Characteristics of Base Metal


*When the bearing is to be used at temperatures exceeding 100℃ it is necessary to provide a margin on the PV value at the design stage.*In the case of high strength brass base metal and the high strength special copper alloy base metal, depending on the conditions of usage, for example when the bearings are at very low speeds near to V=0, the bearings can be used at pressures higher than those given in the table above.

The basic principle of Daido Metal's global strategy is to carry out production as near to the customer as

possible while offering products and services of the same quality as in Japan. In response to reorganization of

the industry in the international community and other upheavals in the market, we have already established

production bases and joint-venture companies overseas.
