1.PTFE with lead 0.01~0.03mm
2.Porous bronze 0.2~0.3mm
3.Steel backing 0.7~2.3mm
4.Tin-plating 0.005mm or copper plating 0.008mm
1. PTFE and fibre can protect the shaft while in operation.
2. It is suitable for the machine required harmless to people because of Lead-free.
3. Goodload capacity and anti-wear.
4. Bronze and steel have good thermal conductivity.
5. Anti-corrosion because of surface plating.
6. It is widely used in general machines, and suitable for food machine, pharmaceutical machine, tobacco machine etc. It will subsitute SF-1 in future because of environment protection.
