Product Description

Electric Appliances​ Engineered Plastic Bushings

Wrapped composite dry sliding bearing steel PTFE


Rolling bearing is a kind of rolling bearing, which is made of high quality cold rolled steel plate, sintered porous spherical bronze powder in the middle, and then rolled on the surface of porous spherical bronze powder with modified polyformaldehyde and rolled.
This type of bearing is required to be coated with lubricating grease during assembly due to its regular surface rolling arrangement and oil storage holes with helical Angle. It is especially suitable for the occasions where it is difficult to form fluid lubrication under high load and low speed. The oil storage holes on the surface can ensure the optimal oil distribution, and long-term maintenance is unnecessary.

viiplus tri-layer low maintanence plain bushing have a base of lower carbon steel, onto which a porous bronze layer is sintered. Acetalcopolyer (POM) is impregnated into the intersice of this bronze layer after rolling process completed. Lubrication indents are stamped into this layer. POM has good physical & mechanical properties, also has certainly chemical properties. This material has good machining performance if required.



1. Self-Lubricaying Layer POM 0.3-0.5mm. After rolling process completed, POM are filled in intersice of bronze layer, lubrication indents are stamped, which are full of oil grease, which will be removed and transferred on the mating surface, forms a physically lubricating film, which will reduced the firction coe. and protect the mating shaft.
2. Porous bronze layer; The layer provides bonded strength of self-lub. Layer.
3. Steel Backing The layer provides load & thermal conductivity
4. Copper / Tin layer.

Electric Appliances Self Lubricating Plastic Plain Bearing


  • is a dry sliding bearing with PTFE sliding layer. Lubrication is therefore not necessary, but basically possible!


Special dimensions are available on request
*If you like to use lubrication nonetheless, please remember to lubricate the sliding bearing regularly.
