ABSTRACT:
A bearing has an outer ring that has an axially outward edge. The inner ring of the bearing has a flange that extends radially outward past the outer edge of the outer ring and defines a slot between them. The external surface of the outer ring is inclined radially inwardly moving axially inwardly from the outer edge of the outer ring for defining a conical section terminating in a circumferential groove. Internally, the outer ring has a borehole in from the outer edge which is also radially inwardly inclined moving axially inward from the outer edge. The outward surface incline directs water away from the slot. The inward surface incline directs water between the rings outward through the slot. The single inclined surface on the exterior of the outer ring may be replaced with a series of inclined surfaces giving the exterior a toothed appearance. A seal may be disposed internally between the outer and inner rings. Attachment boreholes in the flange are at the radially outward tip of the axially edge of the outer ring.
