  • Ball Bearing Preload - GMN Bearing USA

    2021-12-9u2002·u2002This 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.
