  • Do you know the method of tapered roller bearing

    w = 9/8 for roller bearings; Minimum Bearing Load. It has been learned from experience that bearings require a minimum applied load to insure traction for the rolling elements so they roll as the shaft starts to rotate. If the balls or rollers do not roll, they will skid on the moving raceway, wiping away the lubricating oil, and causing damage ...
