    2021-6-2 · This constant contact is achieved through a bearing preload. Radial ball bearings don’t need nonstop contact between the balls and raceway; therefore, a preload is usually not required. However, sometimes a preload on a radial bearing is a better option than switching to a “preload required” angular contact bearing.

    When a thrust ball bearing is rotated at high speed, balls slide on raceway due to centrifugal force and the gyro moment, which often causes the raceway to suffer from smearing or other defects. To eliminate such sliding, it is necessary to mount the bearing without clearance, and apply an axial load (preload) larger than the minimum necessary axial load determined by the following equation.
