• Shaft deflection = diagonal contact with ends of bearing • Longer machine = Higher production costs The longer and heavier the rotor, or the more flexible the shaft, the more shaft deflection (Figure 3) should be expected. Shaft deflection may force the designer to increase the clearance between the sleeve bearing and journal.

Therefore, the motion will be transferred to other components which are forced to accept the unusual motion due to the ball joints being the control arm bushings. By that, the bushings will get damaged easily. Bad ball joint can cause many damage to your car. Secondly, worn ball joints can lead to car accidents when it completely breaks.

Warning Failure to observe the following warnings could create a risk of serious injury. Tensile stresses can be very high in tightly fitted bearing components. Attempting to remove such components by cutting the cone (inner race) may result in a sudden shattering of the component causing fragments of metal to be forcefully expelled.
