In order to allow the mounting of a larger number of rolling bodies (41a) in the annular rolling track (raceway) (41) interposed between the rings of the roller (4), the periphery of the inner ring (42) has a notch (42a) cut in it which allows the insertion of a large number of rolling bodies and which is subsequently closed by a plug (43), grooved on its outer face in order to complete the said track. <IMAGE> |
