Wear resistance piston ring specially developed for the pneaumatic pump industrial application. It is easier to be installed comparing with the PTFE piston ring. Standard materials CSB-EPB®. ● Good wear resistance; ● Easy assembly; ● Maintenance free and self-lubricated; ● Corrosion resistance and light weight.
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 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.
CSB® plastic wear resistance washer. Suitable for a fitting to the uncontrollable axial space in order to reduce the vabriation and noise during the operation.
Suitable for the application where the CSB® plastic clip bearing is hard to be located. The requirement of the fitting hole is not critical and the set screw could be secured without any risk of moving.
Thin-walled plastic bearing for quick installation. It is made with CSB-EPB3M material wich is flexible for dimension viriation. Alternative material CSB-EPB7 is also available for special wear resistance requirement.
The self-lubricated bearing is developed specially for the metal plate fitting. It is made with the CSB-EPB3M material which is good at shock absorbtion and wear resistance...
CSB® plastic bearings are highly wear-resistant plastic bushings, flange bearings and thrust washers made of composite materials. The working temperature CSB-EPB® plastic bearings up to 250 °C...
