Axis; If the accuracy of the casing is not good; the shaft accepts its influence; it cannot carry forward the required function. For example, if the device has some shoulders, the accuracy is not good; the inner and outer rings will be skewed. In addition to the bearing load; Load; reduce the fatigue life of the bearing; more severe will become the damage of the cage; the cause of sintering.
Others; the deformation of the outer casing due to external load is not large. The demand can fully support the rigidity of the bearing; the higher the rigidity; the better the bearing noise and load distribution.
Under normal operating conditions; turning final machining or fine boring finishing can be done. However; for rotary runout, severe noise demand and load conditions are too harsh;
When placing more than two bearings in the whole casing; the cooperating surface of the outer casing should be painted to be perforated. Secondly, the outer casing is prone to deformation of the thin-walled outer ring;
