Material organization
1. The mixture of PTFE and fiber 0.01~0.03mm can form a good transfer film to protect the grinding shaft and provide the self-lubricating performance of the bearing.
2. Copper powder layer 0.20~0.35mm, with good bearing capacity and wear resistance, 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. Copper/tin plating layer 0.002mm, so that it has better corrosion resistance.
