The bearing stiffness and bearing preload force

Under axial load, radial displacement of the bearing ring of thin section angular contact bearing is not negligible, but based on the contact analysis of Hertz theory does not consider these factors.

  With the development of CAE technology, finite element analysis technique is widely used in the bearing, and has a relatively high accuracy.

  As everyone knows,the pretightening force of reasonable bearing design can not only to improve the turning precision bearings and reduce vibration and noise, but also can prolong the working life of bearing. the bearing rigidity is an important basis for bearing preload selection.
