Self-aligning ball bearings of the Normal tolerances for dimension of inner diameter and outer diameter dimension is based on manufacture, bearing inner ring and shaft, combined with the tightness of the outer ring and housing bore can be achieved only through tolerance and control journal housing bore tolerances to achieve. Tie in with the base of the bearing inner ring and shaft hole, used in conjunction with bore of bearing outer ring axis.
The 1th, you want to keep the self-aligning ball bearing and its surrounding environment clean
　　Saying this I do not have to know about it, even the invisible dust into the bearings, also SKF bearing wear, to put it plainly, eye rubbing may not the slightest sand, is a reason!
2nd, be careful and accurate when using install installing

Correct choice of tie, you must know the actual loading conditions of SKF bearings, temperature and other requirements, and is actually very difficult. Therefore, in most cases is selected based on using refinements meet.
