27/7/2018· The static safety factor is the ratio between the basic static load rating and the maximum coined static load applied to the bearing. It can range from 2 for smooth operating conditions with a low risk of vibrations, to as high as 5 or 6 for appliions that may be subjected to severe shock loads.

The bearing safety factor, or safety modulus fs, is the ratio of the basic static load rating C or the equivalent load P on the bearing. When the use conditions are normal operation, a safety factor of 1.0 is typical. If the bearing system may be subjected to possible shock loads, the designer may wish to increase the safety factor to 1.5.
