The case wheel wear test machine is used for the wear test of small wheels, such as suitcases, roller skates, childrens cars, wheelbarrows and wheels. The wheels bear a load at the same time. This method is used to simulate the loading of the traveling box wheels on the ground, so as to test the wear resistance of wheels. The wear resistance and overall structure of the wheel material can be measured without wear and deformation. The results of the test can be used as a reference for improvement.
