What's the difference between dynamic load capacity

The static safety factor is the ratio between the basic static load rating and the maximum combined 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 applications that may be subjected to severe shock loads S 0 = static load safety factor
