Angular Contact Ball Bearings - an overview | ScienceDirect Topics

Taper roller and angular contact ball bearing life is considerably influenced by the slackness or tightness to which the bearings are originally set (Fig. 6.28). The graph shows that if the bearings are heavily preloaded the excessive elastic distortion, and possibly the breakdown in lubriion, will cause the bearings to wear rapidly.
