Products:PFC-1 wear rings

The standard wear ring is used to guide the piston and the rod in a hydraulic cylinder and prevent metal-to metal contact of moving parts.Our PFC-1 wear ring is high-strength laminated material based upon the thermosetting phenolic resin and reinforced with high-quality cotton fiber and finally finished with heat solidifying process under certain pressure and temperature.


Material structure: phenolic resin + cotton fiber


Typical Application:

Guide rings and support rings of hydraulic cylinders

Bushings for pivot axles for vehicles and engineering machineries

Guiding sleeves for the vertical pillar of hydraulic machineries
