In practice, conveyor rollers tend to use bearings mounted on a shaft passing through a roller and it is desirable to provide a less costly arrangement. For this purpose, the invention provides a unit having inner and outer races, receiving suitable bearings (26) and being rotatable with respect to one another about an axis of rotation. One of the races (24) extends from a mounting element (24.5) in the direction of said axis and is fixed rigidly to the element. When the mounting element is attached to a support, the one race forms the sole carrier for the other race and the bearings, and any roller tube carried thereby. The specification also discloses a method of forming such a unit primarily from pressed steel. <IMAGE> |
