Bearing Supports

Rockford Ball Screw offers custom bearing mount and support solutions for common sizes of standard ACME and ball screws.

Every screw assembly functionally requires a means of supporting the rotational axis of the screw and absorbing the radial and axial force components, e.g.

  • Bearing support utilizing rolling element bearings
  • Sleeve and rolling element bearing combination
  • Static screw mounted into a structure with a rotating nut

It is recommended that only axial force vectors are transmitted directly into the axis of the ball screw to obtain optimal and in some instances functional performance & longevity.

All of RBS bearing mounts are furnished sealed and greased from the factory. Bearing mounts can be shipped loose for customer installation or preassembled to the screw at their factory.
