What material is the oil-free wear-resistant bearing made of?
Oil-free wear-resistant bearing is a self-lubricating bearing, which is composed of 4 layers
1. The mixture of PTFE and fiber 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 carrying capacity and wear resistance, and good thermal conductivity can transfer the heat generated during the operation of the bearing in time. The composite material can penetrate into the gap of the copper powder ball to improve the bonding strength.
3. Low carbon steel provides good load-bearing performance and heat transfer.
4. The copper/tin plating layer is 0.002mm, which makes it have better corrosion resistance.
