GB20 Nonmetallic rolling bearings
GB20 series of non-metallic rolling bearings main PP, UPE material cross for the relatively weak acid environment, for most acid / base / salt / solvent / oil / gas and sea water corrosion environment. With the general plastic bearings of oil-free self-lubricating, anti-magnetic insulation properties, but lower mechanical strength, easily deformed, it does not apply to larger loads and higher speeds, comparatively speaking, UPE materials have better strength , low friction characteristics and low temperature application characteristics (down to a 150 ℃).

Applications
EP material possesses a series of excellent self-lubricating properties and wear resistance are mainly engineers take full advantage of the self-lubricating material modification technique, using high-strength fibers in high-performance engineering plastics to improve the material and bearing special grease reduced friction coefficient (Figure 1), thereby improving the wear resistance of composite materials to extend the service life of bearings.
Performance engineering plastics as the base material is mainly used as wear-resistant carrier;
Reinforcing fibers improve the impact resistance and bearing in bearing;
Special grease reducing the coefficient of friction from self-lubricating bearings.
