What are the oilless bearings?
SZB 01 self lubricating multilayer composite bearing iron base + copper powder lubricant + PTFE (PTFE mixture)
SZB 02 boundary lubricated bearing iron base + copper powder lubricant + POM (polyoxymethylene mixture)
Sintering of iron base + bronze powder for SZB 03 bimetallic bearing
SZB 05 inlaid solid lubrication bearing solid copper, inlaid solid graphite lubricant
SZB 06 powder metallurgy bearing powder copper and iron, etc
SZB 09 bronze rolling bearing bronze base + copper powder + PTFE (PTFE mixture)
What material is oil-free wear-resistant bearing made of?
Oil free wear-resistant bearing is a self-lubricating bearing, which is composed of four layers
1. The mixture of PTFE and fiber is 0.01 ~ 0.03mm, which can form a good transfer film to protect the grinding shaft and provide the self-lubricating performance of the bearing.
2. The copper powder layer is 0.20 ~ 0.35mm, which has good bearing capacity and wear resistance, and good thermal conductivity can timely transfer the heat generated during the bearing operation. The composite material can penetrate into the gap of copper powder ball and improve the bonding strength.
3. Low carbon steel provides good load-carrying capacity and heat transfer.
4. The copper / tin plating layer is 0.002mm, which makes it have better corrosion resistance.
