deva.metal®maintenance-free

Where to use

deva.metal® is a self-lubricatingbearing material manufactured byadvanced powder metallurgy. It is fullycompacted, unlike oil-impregnatedporous bronze materials that are weakby comparison. deva.metal® is provi-ded with an evenly distributed solidlubricant throughout its metallic matrix.deva.metal®

- is suitable for dry running at slowsliding speeds and high loads,

- is stick-slip free,- has high resistance to temperature

and corrosion,- is insensitive to contamination and

edge pressures,

- can be easily machined if required.

Reference applicationsIron and steel works, furnace con-struction, fans, foundry machinery,waste water cleaning plants, water-,steam- and gas-turbines, pumps andcompressors, food and beverageindustry machinery, packingmachinery, apparatus engineering,mechanical handling equipment,etc.

Where to use

deva.bm® is a thin-walled self-lubri-cating composite sliding material.It consists of a backing made ofstandard steel, stainless steel orbronze with a deva.metal® layerapplied in a combined rolling/sintering process. deva.bm® offersbasically the same bearing char-acteristics as deva.metal® but iscapable of handling even higherloads and offers an economicsolution to many bearing problems.

Where to use

deva.tex® is a high performance self-lubricating sliding material with aglass-fibre reinforced carrying layer.The machinable sliding layer con-sists of fibres which are embeddedin epoxy resin. The resin carries PTFEas lubricant for excellent tribologicalperformance.deva.tex® bearings are available instandard dimensions up to 200 mmaccording to DIN 1850 and arecharacterized by a very highcorrosion and wear resistance. Theyare insensitive to contamination aswell as to vibrations and shockloads. Custom dimensions are also

available due to the machinable in-ner and outer layer.

Where to use

GLYCODUR® F sliding bearingsconsist of a 0.2 to 0.4 mm poroustin bronze layer sintered onto acopper plated steel base. The poresof this layer are filled during a rollingprocess with PTFE and other frictionand wear reducing additives. A 5 to30 µm top layer made of the samematerial forms the running-in layer.GLYCODUR® F sliding bearingscombine the mechanical propertiesof the sintered bronze with thesliding and lubrication properties ofa PTFE mixture.

The structure of this composite ma-terial results in good dimensionalstability and good thermal con-ductivity.
