1 Bearing Life and Load Rating

In the case of rotation in certain constant speed, the basic rating life can be expressed in a total rotation time as well. 1-3 Basic dynamic load rating. A given static radial load under which a bearing theoretically endures basic rating life of one million rotations is referred to as a basic dynamic load rating. 1-4 Dynamic
