GPM-40 microcomputer controlled rolling contact fatigue test bench

1. Main uses

The GPM-40 microcomputer controlled rolling contact fatigue test bench is used to simulate the failure test of rolling contact parts such as bearings, wheels, rollers, etc., by applying a constant load to the rolling or rolling plus sliding contact specimen, so that the contact surface is subjected to cyclic contact stress.By controlling and changing load, speed, slip rate, time, friction partner material, surface roughness, hardness and other parameters, the test is conducted to evaluate the comprehensive performance of the sample material.Meets the requirements of standard GB10622-89 rolling contact fatigue test method for metal materials.
