PFC-3 Polyester Fiber Fabric Phenolic Wear Rings

The guide ring or wear ring guides a hydraulic cylinder piston and rod and absorbs lateral forces. Preventing metal to metal contact between the moving parts of the cylinder, for instance between the piston and the cylinder or the rod and the cylinder head. The advantages of these non-metallic guide rings (compared with traditional metal guide rings) are, among others, a high bearing load capacity, the elimination of local stress concentrations, wear resistance, a low coefficient of friction and low maintenance costs.

PFC-3 Material Structure:

 Phenolic resin + polyester fiber

PFC-3 is a kind of composite material of high strength, taking thermosetting, linear phenolic as basic materials, and taking high quality and strength polyester fiber fabric as strengthening material. It is composed by advanced technology under the certain temperature and pressure.

PFC-3 Material Advantages:

high load sustainability

good heat, wear and shock resistance

excellent dimensional stability and flexibility

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:

It is suitable for making orientating and supporting ring of high pressure cylinders (like those in excavators, piling machineries, mining machineries etc) working under the condition with strong shock. By adding into some solid lubricants, it also can be used in making mechanical components such as bushings, bearings, thrust washers and so on.
