Single row angular contact ball bearings can accommodate axial loads in one direction only. This type of bearing is typically adjusted against a second bearing. Their bearing rings have an upper and a lower shoulder and are non-separable.

Ball screw support bearings are designed to provide maximum axial rigidity and improved feeding accuracy for use with precision ball screws. They are high accuracy angular contact thrust bearings which are superior to combinations of standard angular contact bearings or arrangements of radial and thrust bearings for ball screw applications.Double direction angular contact thrust ball bearings . Enable location of spindle shafts axially in both directions. Available in two different series and intended for mounting with corresponding cylindrical roller bearings in the same housing bore, for simplified machining of the housing bore.
