Steel Backed PTFE Bushings Self Lubricating Bearing in reciprocating motion
1. Product Description
Steel Backed PTFE Bushings Self Lubricating Bearing in reciprocating motion is made of steel base, bronze powder and excellent PTFE layer,particularly suitable for bushes in reciprocaing motion,and the properties are similar to DD2 type product in foreign country. It shows better performance under working condition of without oil lubrication.

3. Application
Steel Backed PTFE Bushings Self Lubricating Bearing in reciprocating motion are widely used in shock absorber,pneumatic industries,oil cylinder, motor etc.
4. Advantages
This product is wear resistant,and so can keep the lubricating oil clear after long period of working.Meanwhile it can protect the mating furface from wearing. The product is lead-free environmental protection. Oil-free or minimal oil condition, maintenance-free or fair need a little maintenance, low coefficient of friction, long service life and thin, light wall, which can reduce the volume of the machine.No absorption to water/oil,small coefficient of thermal emption,good thermal conductivity and size stability.
