摘要

The rolling bearing cage (5) fits around the shafts of a roller driven by an electric motor mounted inside it. It has external ribs (8), some of which are larger in diameter than the internal diameter of the roller. The cage is inserted into the roller and these ribs deform to hold the cage in place.
