The deep ditch ball bearing is pushed each other between steel ball and ditch one while bearing the load, exposed to neighbouring area deforming and stress of the position, because of contacting the surface very small, even the load is not too large, it may be quite big to exposed to the stress. It determines the bearing capacity of the bearing to exposed to the stress, its influence factor is mainly exposed to pressing the stress and is distributed of the surfaces, especially shear the stress and is distributed.
The inner circle of bearing moves, the outer lane is rotated, the loaded direction on the axle does not change generally, in this way a little receiving strength is maximum on the inner circle, the ones that produce on this point cut the stress in every cycle (steel ball has rolled in this point) Big than other point, produce tired to destroy first. But to whirling outer lane, it changes to bear some maximums of cutting stress, and the girth of the outer lane is relatively large, so to exposed to fatigue life is longer than the inner circle. On the contrary, fixed to the outer lane, the bearing that the inner circle rotates, the inner circle is more tired and more longe-lived than the contact of the outer lane.
To sum up, in case of low-speed, the inner circle is rotated or the outer lane is rotated, the impact on life-span of the bearing is not very great, but under rotating the operating mode at a high speed, the inner circle rotates and contacts fatigue life than the bearing that the outer lane rotates much longer, the advantage is obvious.
