PFC-21 Synthetic Fiber Polyester Resin Wear rings

The function of a wear ring (or Guide ring) is to guide the piston and piston rod of the hydraulic cylinder, absorbing transverse forces. At the same time, the Wear Ring prevents metal-to-metal contact, optimizing the performance of the sealing system.

PFC-21 Material Structure: 

Polyester resin + synthetic fiber

PFC-21 is composed of specialty synthetic fiber, reinforced polyester resin and self-lubricating micro powders. PFC-21 features in dimensional stability, good wear resistance and low friction, it has outstanding advantages in oilless or low-oil conditions.

Wear Cut Styles:

Angle cut rings improve bearing stress at the gap. These rings tend to suit reciprocating movement.
Straight Cut, also known as Butt Cut rings are the easiest style to install in many applications. Straight cut rings are best suited for rotary movement.
Step cut rings also improve bearing stress at the gap. However, they offer better resistance to contaminants and spike loads. This type of design offers the best level of performance.

Typical application:

Guide rings

Marine and Offshore Platform Bearings

Water Conservancy, Hydropower System Bearings

Food Machinery Bearings
