  • AN INVESTIGATION OF SCUFFING FAILURE IN ANGULAR

    2018-3-7 · Bearing failures are one of the most common failure modes in the rotating machinery and equipment. Angular contact ball bearings are widely used considering their ability to carry the loads in both axial and radial directions, durability and low friction. The smooth functioning of these bearings greatly depends on the bearing load rating, material, type of fit with which it is assembled, the ...
