Ball Screw Support Bearings Supply
Ball screw support bearings are specially configured and designed to provide extra axial strength, accuracy and elevated thrust loading for use with ball or lead screws. Typically, ball screw support type bearings are angular contact bearings, which are available in duplex, triplex and quadruplex configurations.Other ball screw support type bearings contain separate thrust and radial roller bearings in a single assembly. Both Metric Series and Inch Series are available.

Typical tolerance and fit specification is line-to-line to loose for the installation shaft and housing. Bearings may be supplied in sets which are clearly match-marked on their outside diameter surfaces to indicate correct positioning of each bearing.
Important considerations when specifying ball screw support bearings are, load ratings, size - design envelope requirements, and operationing speed. Most manufacturers provide detail load and life rating specifications for thier bearing products.
