  • Bearing Tolerances & Clearances - American Roller

    On small cylindrical roller and ball bearings, it can be easily measured with a dial indicator gage by laying the bearing on one side, fixing one race, and pushing the other race one direction and pulling back 180º. IRC is the total movement; however, this method does not lend itself to large, heavy industrial bearings.
