Ball Screws - Bearing supports
Design and Theory
For most applications, the ball screw end(s) will be supported in a bearing. Configurations that are commonly used to support the ends of a ball screw are:
End fixity
End fixity
- A deep groove radial bearing (floating simple support)
- A pair of back-to-back, angular contact bearings to control end play (fixed support)

Four combinations of bearing supports are typically used for selection purposes. Fixed-free offers the least support where Fixed-Fixed offers the most support.End fixity
