The spring acts on the outer ring of one of the two bearings. This outer ring must be able to be axially displaced.
Get Price2021-5-24 · 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.
