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.

Conveyor roll bearing

The specification discloses a bearing assembly including a removable shield which prevents the entry of dirt and other contaminants into the space between the bearing races and yet allows easy maintenance and inspection access to the bearing interior when desired. A grease fitting is provided through the shield and held in a predetermined position for access by automatic relubrication equipment by the cooperation of a noncircular aperture in said shield received over a noncircular shield support at the side of the inner race. Preferably, the shield is held on the shield support by a resilient, split retaining ring received adjacent the shield in a groove in the shield support.
