1. Main uses
The microcomputer-controlled rolling contact fatigue test bench is used to simulate the failure test of rolling contact parts such as bearings, tires, rolls, etc. A constant load is applied to rolling or rolling plus sliding contact specimens to make their contact surfaces subject to cyclic contact stress. By controlling and changing the load, speed, slip rate, time, friction material, surface roughness, hardness and other parameters of the test, in order to evaluate the comprehensive performance of the sample material. Meet the standard GB10622-89 metal material rolling contact fatigue test method requirements.
