Material POM and PA have excellent mechanical strength and wearing resistance, POM / PA Precision Plastic Bearings is suitable for manufacturing precision plastic bearings. With good self-lubrication performance and low friction coefficients, POM / PA Precision Plastic Bearings could be used in precise and high speed application.

The Density of POM plastic bearings is 1.42 g/cm3, PA is 1.14 g/cm3, Sliding friction coefficient is 0.34 and 0.35, Short-time highest application temperature is 150℃ and 170℃.Plastic bearing made with POM is the most extensive sort of all the plastic bearings. Generally the inner and outer rings made with POM or PA, Cage made with PA66 and the balls made with glass, stainless or ceramic. POM / PA Precision Plastic Bearings bearings could be used in some alkaline environment but not proper to some acid corrosion environment.
