Introduction to Various Engineering Plastic Bearing Materials

The inner and outer rings of precision engineering plastics bearings are usually made with POM and PEEK, rolling elements with glass balls, stainless steel balls and ceramic balls, cages with PA66(strengthened with glassfiber) and PEEK. POM and PEEK materials are suitable for precision processing. The precision and tolerance of plastics bearings made of POM and PEEK are higher than that of traditional plastics bearings. Precise and high speed rotation working conditions are applicable.
Acid/alkali-resistant plastics bearings made with HDPE, PP, UPE, PE-UHMW, provide multiple solutions according to different application conditions. They have impressive resistence to acid, alkali, salt, solution, oil, gas and sea water, and ensure ideal durability and life expectancy.
Corrosion resistant bearings made with PTFE and PVDF are applicable in the environments of strong acid and strong alkali. PTFE can be used in all strong acid and strong alkali even in 98% fuming sulfuric acid and fuming nitric acid.
High temperature resistant bearing is made with PEEK and PI which are tested to be the ideal materials. PI can be used at 300°C in long term and at 350° in short term.
