Abstract

A rolling bearing for lengthwise movement with respect to a shaft has a housing with a cage for guiding endless rows of rolling elements. Race rails extend axially in the housing for radially outwardly supporting rolling elements in the portions of the portions of the lengths of the rows thereof adapted to receive loads. The race rails have first sides with convex curvature in the axial direction, and second sides opposite the first sides that extend straight in the axial direction, the race rails being adapted to be assembled in the bearing with selected ones of the sides thereof being directed radially outwardly. Both sides of the race rails may have axially extending guide grooves.
