Abstract

A linear-motion ball bearing assembly wherein a metal cylindrical shell has an inner bore surface defining load zones and outwardly spaced return passages for balls in endless raceways; the shell has outwardly extending longitudinal ribs, with plastic injection molded onto the bore of the shell to form guide walls for balls in the load zone and along the ribs of the shell to form return guide passages communicating with the load zone passages.
