A sealed anti-friction bearing including an outer ring and inner shaft and two axially spaced sets of races defined in them for rolling element balls, and a respective seal between the outer ring and the shaft axially outward of each of the sets of rolling for elements defining an enclosed space between the seals. A die cast housing cast outside the outer ring. In the axial region of each set of races and their respective adjacent seal, the cast housing including a plurality of axially extending, circumferentially spaced apart, radially projecting ribs generally arranged in a “star shape”. The ribs at one set of races open radially outward of the housing and the ribs at the other set of races open radially outward into the remaining solid body of the housing.

In combination, a cast bearing housing and an anti-friction bearing housed within the housing, the combination comprising: the bearing comprising: means defining an inner race for a row of bearing rolling elements; an outer ring around the inner race, the outer ring having an outer race defined in it which is placed axially for defining a cooperating set of the inner and outer races for rolling elements; a row of rolling elements received int he set of the inner and outer races for rolling therealong; and seals for the anti-friction bearing between the means defining the inner race and the outer ring and located axially to the sides of the row of rolling elements for defining a sealed space including the races and the row of rolling elements; the housing comprising: a cast housing cast around the outer ring, the cast housing being integrally cast in such a way as to include a plurality of circumferentially spaced apart, radially projecting ribs for rapidly diverting heat away from the bearing as the housing is cast, each of the ribs extending axially, the ribs being located generally in the axial region of the rolling element races and of the seals.
