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
PFC-3 Material Technical Parameters:
Wear Cut Styles:
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.
