Required basic static load rating

When determining bearing size based on the static load carrying capacity a given safety factor s0, which represents the relationship between the basic static load rating C0 and the equivalent static bearing load P0, is used to calculate the requisite basic static load rating.
The required basic static load rating C0 can be determined from

C0 = s0 P0


C0=basic static load rating [kN]
P0=equivalent static bearing load [kN]
s0=static safety factor
Guideline values based on experience are provided in table for the static safety factor s0 for ball and roller bearings for various applications requiring smooth running.
At elevated temperatures the static load carrying capacity is reduced. Further information will be supplied on request.
