The selection of safety factor bearing on certain changes to bear a greater load, particularly in the operation have a greater impact on the role of the rotating load bearing, dynamic load rating in accordance with choice of the bearings must be re-rated static load in accordance with well-tested. If the speed of the lower bearing on the functioning of modest accuracy and friction torque can be allowed to have a greater permanent deformation J now check So <1, the other hand, then So> 1.

The Thrust Spherical Roller Bearing, regardless of their rotation or not, should be taken S. ≥ 4. In addition, the choice by the rated static load bearing, the bearing must also pay attention to fit and the stiffness of the site. The stiffness of the lower bearing box, they can select a higher factor of safety; the other hand should be lower safety factor.
