Abstract: The specification discloses a light-duty conveyor roll bearing which is quiet, static conductive, and capable of operating at relatively high speeds. The bearing includes a stamped, cup-shaped outer race; an inner race positioned therein; and an end cap crimped to the rim of the outer race to shield one side of the ball raceway, to provide a thrust bearing surface for the balls, and to provide a seal contacting surface. Opposite the end cap, the outer race extends radially inwardly adjacent to or beyond the inner race to shield the other side of the ball raceway. A graphite-filled, electrically conductive, polymeric hub supports the inner race and includes an annular seal contacting the end cap to seal the one side of the ball raceway.
