▊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.

Type	Material	Application temperature	Features
PPR3	CSB-EPB3	-40℃/+130℃	Strong and durable, low-cost
PPR7	CSB-EPB7	-40℃/+90℃	High wear resistance
PPR13	CSB-EPB13	-50℃/+90℃	Standard material, anti-wear
PPR19	CSB-EPB19	-40℃/+150℃	High-temperature and anti-wear
PPR21	CSB-EPB21	-40℃/+200℃	High-temperature and chemical resistance
PPR23	CSB-EPB23	-100℃/+180℃	FDA grade and extreme teperature applications
PPR25	CSB-EPB25	-100℃/+180℃	Low and high temperature

▊Assembly design

CSB-PPR slipped gap design allows an easy assembly, simply open the bearing by hand from the gap and position the bearings to the required location until it is pushed into the mounting groove.

▊ 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.
