摘要: A ball bearing for linear movement on a shaft has a cage with oval guideways, and an outer sleeve surrounding the case. The cage has axially extending raceways for guiding loaded balls, the ends of the raceways joining radially outwardly directed transitions. The transitions are weakened by transversely extending grooves or slots, to provide resilience. The raceways may be axially extending radially inwardly directed ridges having central axially extending grooves, and the transitions may have V-shaped recesses with their apices at the ends of the grooves, to define two-point contact with the balls in the transition area of the bearing. A split sleeve may surround the outer sleeve for additional support.

摘要: A method of manufacturing a seamless outer sleeve for a ball bearing, wherein the sleeve is formed of a hollow cylindrical tube section of uniform wall thickness, with race sections paralleling its axis, projecting radially inward, and formed by non-cutting methods, after which the outer circumference of the sleeve section is cut away by the amount of the depth of the race sections. The race sections for the load-carrying balls are non-cuttingly formed by embossing adjoining ends of race sections together with race transitions which are inclined with respect to the longitudinal direction. The race sections can be slightly arcuate with respect to the longitudinal direction of the sleeve and formed by rolling.

摘要: 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.
