Abstract

A rolling bearing assembly for lengthwise movement with respect to a shaft has an outer sleeve with internal races, and a cage guiding endless rows of rolling bodies in the bore of the outer sleeve. The cage has a slit extending axially and radially therethrough, and the cage portion aligned with the slit is radially moveable, so that an entire row of rolling bodies adjacent said slit may be radially moved into a race formed in a shaft in the bearing. The sleeve may have a second slit spaced from the first slit. The second slit may be only partial, to define a region of bending, or may extend completely through the outer sleeve to define a segment, with the first slit, that is radially moveable.
