Abstract

See full text

A rigid support bearing for a rotating shaft has bearings arranged concentrically around the shaft instead of spaced axially and is used in a screw drive telescoping mast assembly. An axial drive screw is centrally located in the mast assembly for extending and retracting the tubular sections. A lower bearing assembly supports the drive screw and uses the concentric bearing arrangement to reduce the nested height of the mast.
