PFC-21 Rod and Piston Wear Rings
Advantages in using PFC-21 material:
Excellent dimensional stability
Good wear resistance and low friction
Reduces hydrodynamic pressure problems in the guide system
PFC-21 rod and piston wear rings
PFC-21 rod and piston wear rings, which are also known as guide rings or wear bands, are used in various applications to prevent metal to metal contact, lessen vibration and increase stability, as well as absorb transverse forces. This material is composed of specialty synthetic fiber, reinforced polyester resin and self-lubricating micro powders, it has ourstanding advantages in oilless or low-oil conditions.
Material structure: specialty synthetic fiber + polyester resin + self-lubricating micro powders
Typical Application:
Engineering machinery components
Hydroelectric power components
Food machinery bearings
