To meet these requirements, screw drives can be supported at both ends by SKF super-precision angular contact thrust ball bearings. The bearings provide a high degree of axial stiffness, high axial load carrying capacity, accommodate high speeds and rapid accelerations, and offer very high running accuracy.

A ball screw is a mechanical device for transforming rotational motion to linear motion. On a ball screw, a threaded shaft provides a spiral raceway for ball bearings, which act as a precision screw. Ball screws apply or withstand high thrust loads with minimal internal friction.
TIMKEN® FAFNIR® SUPER PRECISION BEARINGS FOR MACHINE TOOL APPLICATIONS. INDEX ... Ball screw support bearings with steep contact angles, available in single row, or in housed units, provide high levels of stiffness for the demands of servo-controlled machinery. Sealed double-row
Precision ball screws have a number of bearing balls that transfer the load between the nut and screw. The thread form in which the bearing balls ride is an ogival shape formed from two arcs of the same radius with offset centers. This form is also referred to as a gothic arch.
NTN Ball Screw Support Bearings 278 13. Ball Screw Support Bearings NTN ballscrew bearings are optimized to support a ballscrew. These bearings are categorized as shown in Table 13.1. Because balls are used as the rolling elements, the starting torque of a angular contact thrust ball bearing is less than that of a roller bearing. The 2A-BST type
