Microcomputer Controlled Rolling Contact Fatigue Test Bench

Application

The microcomputer controlled rolling contact fatigue test bench is used to simulate the failure test of rolling contact parts such as bearings, rims, rolls, etc., applying a constant load to the rolling or rolling plus sliding contact specimens, so that the contact surface is subject to cyclic contact stress Role. By controlling and changing the parameters such as load, speed, slip rate, time, friction partner material, surface roughness, hardness and other parameters, the test is performed to evaluate the comprehensive use performance of the sample material. It meets the requirements of the standard GB10622-89 metal material rolling contact fatigue test method.
