Effect of relative movement between bearing races on load ... Springer

The current study presents the influence of relative motion between inner race and outer race in the presence of radial clearance. This relative motion alters the angular positions of any consecutive balls (balls) with respect to the bearing axis. Hence, the quasistatic analytical study shows the effects of alteration in angle of contact on the load distribution by balls. Based on the Hertz ...

Bearing Tolerances Clearances American Roller Bearing

When a bearing's inner race is mounted on a shaft with an interference fit, some expansion of the inner race (roller path or ball groove) occurs. This has the effect of reducing the manufactured or "bench" internal clearance of the bearing. This is a very important consideration when designing a machine.
