Xinzhou and their excellent PTFE and PVDF plastic bearings
As the most typical type, PTFE and PVDF are with the highest corrosion resistant.
PTFE is the most corrosive among the known engineering plastics, can be used under all the strong acid, strong Alkali, including 98%. Nitrate Acid; and it has good performance, PTFE was proven to be working under 180C.
PVDF using temp.: 150C; But PTFE is with low .mechanical strength, poor dimensional stability, big deformation, thus it is not applied to higher load or higher RPM.
Relative speaking, PVDF is with better comprehensive performance, commonly: PTFE or PVDF as inter or outer rings.,PTFE or PVDF cages.
Balls: glass balls, ceramic balls, or stainless steel balls.
