Product Description

1. Main USES

This machine is used for simulating bearing, wheel rim, working condition of roller rolling contact parts such as the failure of the experiment, a constant load applied to scroll or rolling and sliding contact with the sample, the contact surface contact stress by cycle. Through controlling and changing load, speed, slip rate, time and friction spouse parameters such as material, surface roughness and hardness test cases, to assess the comprehensive performance of sample materials. Meet the standard gb*******9 rolling contact fatigue test method for metal materials.
