S Bearings, EZO bearings, Bearing Relubriion Services - Ball Bearing Load Rating
If long life is required, it is preferable to limit the actual load to between 6% and 12% of a bearing’s dynamic load rating. Heavier loads can be tolerated but life will be shortened. AISI440C/KS440 stainless steel bearings will support approximately 80% - 85% of the load figures for chrome steel bearings.

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.
Technical Information: Ball bearing types, selection factors, and …
Ball Bearings. There are several types of ball bearings that fit specific needs. The deep-groove ball bearing, Figure 2 (a), is the most versatile. Radial loads and thrust-load capacities may be approximately equal in this bearing. When it has the proper separator, it is very good for high-speed operation.
