Factors influencing the performance of thin-walled ball bearing effect

When there are clearance fit between mobile crane bearing outer ring and bearing seat hole, the existence of eccentric distance m between the bearing center O and the bearing seat center O ', as shown in Figure 1.

  Because of the existence of the gap, the outer ring of the bearing, isolated point supported state, at this time the thin wall bearings under external load, the outer ring will be deformation occurred, causing the ball bearing load distribution of rolling mill bearing body load distribution and the rigid support compared have changed greatly, at the same time effect the thin-walled ball bearing service life, stiffness properties.
