deva.metal

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, packing

machinery, apparatus engineering,mechanical handling equipment,etc.

deva.bm

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.

Reference applicationsWater turbines, injection moldingmachinery, food and beverageindustry machinery, packingmachinery, printing machinery,apparatus engineering, shut-offvalves, tire molds, etc.

Where to use

deva.bm/9P is a thin-walled, self-lubricating composite sliding materi-al. The sliding layer is applied to astainless steel backing in a combinedrolling/sintering process.PTFE serves as lubricant and offersvery low friction and wear rates.

An optional running-in film can extendthe bearing lifetime under certainoperating conditions.

Reference applicationsWater turbines, injection moldingmachinery, packing machinery, foodand beverage industry machinery,printing machinery, shut-off valves,hydro-mechanical engineering, tiremolds, apparatus engineering, etc.

Where to use

deva.glide is a self-lubricatingbearing material that consists of ahigh-quality bearing bronze withsolid lubricant pockets. A thin filmof solid lubricant aids the running-inprocess if required.deva.glide allows to replace lubri-cated bronze bearings with a main-tenance-free alternative and- is suitable for large dimensions,- has a low friction coefficient,- has a high wear resistance,- allows a high durability.

deva.tex

maintenance-free

Where to use

deva.texis 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 d imensions up to 200 mmaccording to DIN 1850 and arecharacterized by a very highcorrosion and wear resistance. They

are insensitive to contamination aswell as to vibrations and shockloads. Custom dimensions are also

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

Reference applicationsWater turbines, hydromechanicalengineering, agricultural machines,earth moving equipment, railroad

vehicles, shut-off valves, chemicalindustry, apparatus engineering,wind turbines, etc.
