PFC-1 Cotton Fabric Phenolic Wear Rings

The function of a phenolic 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-1 Material Structure: Phenolic resin + cotton fiber

Kintowe PFC-1 composite material 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. 

PFC-1 Material Advantages:

High load sustainability

Excellent abrasion resistance 

Excellent temperature resistance

Good dimensional stability 

Improves seal performance

PFC-1 Material Technical Parameters:

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: 

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