The inner diameter and outer diameter of stainless steel outer spherical bearings are manufactured according to standard tolerances. The tightness of the bearing inner ring and shaft, outer ring and seat hole can only be achieved by controlling the tolerance of the journal and the tolerance of the seat hole. The cooperation between the inner ring of the stainless steel outer spherical bearing and the shaft adopts the base hole system, and the cooperation between the outer ring of the stainless steel outer spherical bearing and the seat hole adopts the machine shaft system.

To choose the fit correctly, it is necessary to know the actual load conditions, working temperature and other requirements of stainless steel outer spherical bearings, but it is actually very difficult. Therefore, in most cases, it is selected according to the use of lapping.

load size

The amount of over-win between the ferrule and the shaft or housing depends on the size of the load, a larger over-win is used for heavier loads, and a smaller over-win is used for lighter loads.
