Abstract
Inner and outer ring spacers include respective load bearing portions, which are positioned on respective sides of a gap of a predetermined size and which confront with each other in an axial direction. Each of the inner and outer ring spacers is divided into two spacer segments along a surface of division extending in a direction perpendicular to the axial direction and passing through the associated load bearing portions. Inner and outer ring divided spacer segments, having the load bearing portions, are simultaneously machined so as to have the same axially measured width. Along therewith, inner ring divided spacer segments, having no load bearing portions, are simultaneously machined so as to have the same axially measured width, thereby rendering the latter axially measured width to be larger than the former axially measured width by a quantity corresponding to the gap.
