Bearings,as important components in contemporary mechanical equipment,mainly support the mechanical rotating body,which can reduce the friction coefficient during its movement and ensure its rotation accuracy.
Characteristic of Plastic Bearing Unit:
1.Excellent chemical resistance, able to withstand all strong acids (including aqua regia) except molten alkali metals, fluorinated media and sodium hydroxide above 300C, as well as strong oxidants, reducing agents and various organic The role of solvents
2. Excellent heat resistance, its melting temperature is 324°C, decomposition temperature is 415°C, maximum use temperature is 250°C, embrittlement temperature is -190°C, and thermal deformation temperature (under 0.46MPa) is 120°C.
