POM High Precision Plastic Bearings
 
Plastic bearing made with POM is the most extensive sort of all the plastic bearings.
Material POM have excellent mechanical strength and wearing resistance, POM High Precision Plastic Bearings is suitable for manufacturing precision plastic bearings. 
The Density of POM plastic bearings is 1.42 g/cm3, Sliding friction coefficient is 0.34, Short-time highest application temperature is 150℃.
Generally the inner and outer rings made with POM or PA, Cage made with PA66 and the balls made with glass, stainless or ceramic. With good self-lubrication performance and low friction coefficients, POM High Precision Plastic Bearings could be used in precise and high speed application. POM High Precision Plastic Bearings could be used in some alkaline environment but not proper to some acid corrosion environment.
