Dynamic characteristics of high speed angular contact ball bearings …

1/1/2001· Abstract. A theoretical research was developed concerning the rigidity and damping characteristics of high speed angular contact ball bearings mounted on grinding machine main spindles. Both film squeeze effects and elastic deformation of the Hertzian contact were considered and an adequate dynamic model is suggested.

Ball screw rigidity: how is it determined and how can it be …

A double ball nut has higher rigidity than a single nut, but the overall effect on the ball screw system’s rigidity is relatively small. While the screw’s material and diameter are generally set by the appliion, the end bearing arrangement (and hence, its influence on unsupported length) is chosen based on factors such as speed, buckling load, and rigidity.
