SF-1W Carbon Steel Pb-free Self-lubricating Bearing
Material Features:
SF-1W is a new type bushing without lead composition which is developed aiming at increasing demands on environmental protection. Besides its wide application on general machines, SF-1W is particularly suitable for food machine, pharmaceutical machine, tobacco machine etc.
Application Feature:
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 substitute SF-1 in future because of environment protection.
