Dimensions

Structure design

CSB-PPR plastic piston ring is designed with slipped gap that ensures easy assembly of the bearings and long term stable operation.

Material design

CSB-PPR plastic piston ring is made from CSB-EPB® materials which is a good wear resistance polymer ensures outstanding wear resistance feature of the bearings under high speed operation condition.

CSB® Bearing Material Chemical Resistance

Please select bearing material and medium...

CSB® bearing material chemical resistance data is a comparison test result of the CSB chemistry laboratory using laboratory specimens or similar chemicals at room temperature 23 ℃, without considering the impact of other temperatures and chemical medium mixtures on the chemical resistance of CSB® bearing materials ; Therefore, this data can only act as a reference. CSB® recommends that the chemical resistance of actual parts should be tested under application conditions and verify the suitability of the bearings.
