The material is based on shock absorbers and lateral reciprocation larger force of special conditions and development of products. It has a very low coefficient of friction and good wear resistance, can be used in the lubrication gap. The major products in automotive shock absorbers, motorcycle shock absorbers, hydraulic cylinder and so on.

1. lubricating ability in off the oil situation, good wear protection film clear advantage;
2. can better protect the shaft surface, reducing wear and tear;
3. Especially suitable for reciprocating motion;
4. because it does not lead, it comply with the environmental requirements;
5. The product is suitable for automotive, motorcycle shock absorbers, various hydraulic cylinders, hydraulic motors, pneumatic components.
Straight sets, flanged bushings, WC thrust washers, skateboards and other non-standard parts and so on.
