Criteria for bearing selection | Schaeffler medias
It is advantageous to apply axial adjustment to the bearings, for example by means of disc springs. Rigidity. Roller bearings are more rigid than ball bearings. The rigidity of a rolling bearing is determined by the type, bearing size and operating clearance. The rigidity increases with the nuer of rolling elements supporting the load.
