Method of making a roller bearing assembly

摘要

A protrusion is formed on the free end of an axially extending lip of an outer race member. The free end of the protrusion is axially and radially spaced from the free end of the remaining part of the axially in-turned lip to permit the passing of a reduced end of a reduced end roller. The reduced end rollers are inserted into the outer race member through the protrusion. After all the rollers are in place within the outer race member the free end of the protrusion is closed by heating the protrusion and pressing the protrusion to provide an in-turned lip of substantially the same shape throughout the circumference of the lip.
