PVDF/PTFE Anti-corrosion Plastic Bearings

As the typical type of fluoroplastic, PTFE and PVDF have the most excellent anti-corrosion performance, Among them PTFE has the best anti-corrosion performance of all the engineering-plastics known to man, PVDF/PTFE Anti-corrosion Plastic Bearings could be used in all the Strong Acid and Alkali application, including HF and smoke formation H2SO4 HNO3 or HCL (98% above) etc., and PVDF/PTFE Anti-corrosion Plastic Bearings could be used in high temperature application. PTFE could be used in 180℃ and PVDF in 150℃. But PTFE has very low mechanical strength, easy to be out of shape and have large Dimension change when the temperature rise or reduce.

The Density of PVDF plastic bearings is 1.77 g/cm3, PTFE plastic bearings is 2.18 g/cm3, Sliding friction coefficient is 0.30 and 0.10, Short-time highest application temperature is 150℃ and 260℃.

So PVDF/PTFE Anti-corrosion Plastic Bearings couldn't be used in heavy load and high-speed occasion. Compared with PTFE, PVDF has better comprehensive performance. Generally the rings and cage were made with PTFE or PVDF, Balls were made with glass, ceramic or stainless.
