Composite Bearings

Our Filament Wound Plastic Self-Lubricating Composite Bearings meet the need for high load, self-lubricating bearings that provide low wear rates in a wide variety of applications. Our composite bearings combine the excellent lubricating properties of filled PTFE with the high strength and stability of an oriented glass fiber wound structure. They employ a tough, high strength composite structure consisting of epoxy-impregnated, wound glass fibers oriented to provide the radial and axial strength required to support high static and dynamic bearing loads. The backing of these composite bearing material is high strength glass fiber with epoxy resin and the lubricating layer of it is PTFE wound fiber or special lubricating fiber. This special structure provides an outstanding erosion resistance making it possible to be used in a marine environment and a low friction coefficient under high load and low speed condition. Our composite bearings can withstand static loads of approximately 61,000 PSI and 20,000 PSI under dynamic loading and are suitable for use in a temperature range of -100°C to +160°C. They have low water absorption; their linear expansion coefficient and thermal expansion factor is similar to that of steel.
