Abstract
An apparatus for mounting face-to-face angular contact bearings to ensure eload control. Face-to-face angular contact paired bearings have inner races and outer races. The inner races of the bearings are fitted on an element to be supported such as a shaft. The outer races of the bearings are fitted in a bearing housing with a first gap .DELTA.1 therebetween. Preloading of the bearings is achieved by inserting preload springs between external surfaces of the outer races and respective bearing housing surf aces. A second gap .DELTA.2 may also be provided between the bearing housing and the external surface of one of the outer races to prevent a change in preload due to thermal gradients.
