PFC-5 Cotton Fabric Phenolic Wear Rings Added With MoS2

Wear rings perform the task of locating the piston and piston rod in the cylinder, absorbing any side loads that arise and preventing metallic contact between the sliding parts. Non-metallic materials are becoming increasingly popular as substitutes for the conventional metallic guides, offering a range of advantages that traditional solutions are unable to match.

PFC-5 Material Structure: 

Phenolic resin +cotton fabric+ MoS2

PFC-5 high-strength composite material is composed of high quality cotton fabric, soluble phenolic resin and MOS2 and processed under certain temperature and pressure. It is capable for oilless or low-oil conditions, thus can apply to engineering machinery, shipbuilding, hydroelectric

generation and so on.

PFC-5 Material Advantages:

good mechanical strength 

excellent wear resistance and heat resistance

absorbing semi-static high shock loading and slight rotate loading

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:

 Engineering Machinery Guide Rings, Bushings, Shaft Sleeves
