Preload with a constant force
Guideline values for the most common spring-loaded bearing arrangements are listed in table 1. The values apply to single CE and ACE design bearings. For bearings in tandem arrangements, the values should be multiplied by a factor equal to the number of bearings preloaded with the spring force. The specified spring preload forces are a compromise between minimal difference in operating contact angle at the inner and outer ring raceways, and axial rigidity at high rotational speeds. Heavier preloads lead to higher operating temperatures.
