ABSTRACT:
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.
