1. PTFE with oil fibre can protect the shaft, while machine in operation.
2. It is of low friction coefficient, anti-wear.
3. Good running in property.
4. It fits well in motion of circumrotation, sway and to-and-fro.
5. It can be used in food machine, pharmaceutical machine etc. due to lead-free.
6. Besides the same function of MP10 in particular fits frequently reciprocating motion with a high side
force, it is widely used in automobile, motor damper and oil pumps etc.

1 PTFE / Pb mixture 0.01-0.03mm, provides an excellent initial transfer film
2 sintered bronze powder0.20-0.35mm, provides Max thermal conductivity away from the bearing surface,
also serves as a reservoir for the PTFE- lead mixture.
3 Low carbon steel, gives exceptionally high load carrying capacity, excellent heat dissipation.
4 copper / Tin plating 0.002mm, provides good corrosion resistance.
Stainless steel bushing is widely used in strong acid and alkali situation, such as chemical industry, pumps and valves.
Lead free bearing is widely used in food machine, pharmaceutical machine
Competitive Advantage:


1. A complete set of testing equipment

2. Rich experience in bushing production
