PFC-2 Cotton Fabric Phenolic Wear Rings Added With Graphite

Wear rings or guide rings provide a bearing surface to center the piston and rod dynamic surfaces in a reciprocating cylinder application. The wear ring prevents metal-to-metal contact and improves seal life performance. 

PFC-2 Material Structure: 

Phenolic resin + cotton fiber + graphite

PFC-2 high-strength laminated material is made of solute phenolic resin containing homogenously dispersed graphite and high-quality cotton fiber and finally finished with heat solidifying process under certain pressure and temperature. 

PFC-2 Material Advantages:

high mechanical strength

excellent abrasion and temperature resistance

sustaining strong vibration under semi-static state 

sustaining impact loads and slight torque loads

working under conditions where oil is little or even with no oil

Wear Cut Styles:




Advantages
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: Hydraulic support, wear rings and guide rings of hydraulic cylinders.
