How many tests can be performed with a pair of wheels?
The wear life of a wheel varies with the surface texture and frictional characteristics of the material tested. Under ordinary conditions, they can provide 10,000 to 50,000 wear cycles. Abnormally short wheel life may indicate incorrect wheel or load selection, too frequent refacing or improper procedure. The wheels have been designed to operate until worn down to a minimum of 1 ¾” (outside edge of label).
