The inner ring 4 can be cramped with a light load (working force), energy loss in caulking by rotary forging is small. Since the grooves 21, the steps 22, or the grains 23 are formed axisymmetric, they can be worked by a lathe in the line, and the working process and working cost are not increased.  <P>COPYRIGHT: (C)2003,JPO
