Noise Testing

The abbreviation GPR stands for 100% noise-tested ball bearings. We test the amplitude of the vibrations generated by the ball bearings at the set speeds and frequencies.

These tests are necessary to ensure uniformity of the production run or to guarantee compliance with customer requirements. The basis for attaining this goal is constant monitoring of the parts for roundness and surface finish.

The testing method should be selected according to the application the bearing will be used in.
