PAI plastic pepper ball has the characteristics of high temperature resistance, good wear resistance, good self-lubricating performance in the high temperature environment of 250 degrees, better resistance than other plastics, and excellent dimensional stability. In the high temperature environment and high pressure environment, PAI plastic pepper ball is the most selective at present, and its comprehensive excellent physical properties even exceed the physical properties of metal balls in some convenience.

PAI plastic pepper balls are used in many high-pressure and high-temperature environments, such as plastic bearings. Because of their excellent self-lubricating performance, the plastic bearings made of PAI plastic pepper balls can be used in high-temperature and acid occasions. Coupled with their excellent wear resistance, PAI plastic pepper balls are the most used plastic balls in plastic bearings.
