Substrate properties
It is suitable for working parts that can"t be refueled or difficult to refuel. It has good wear resistance, small friction coefficient and long service life. It has good running performance, low noise and good corrosion resistance. The transfer film formed during operation plays a role in protecting the grinding shaft. The role of no biting axis phenomenon; the processing requirements of the grinding shaft is reduced, reducing the user"s processing costs. It is widely used in general industry.
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. The copper powder layer is 0.20~0.35mm, which has good bearing capacity and wear resistance. Good thermal conductivity can transfer the heat generated during the operation of the bearing. 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 is 0.002mm, which makes it have better corrosion resistance.
