Abstract
A sealed anti-friction bearing comprising a bearing surrounded by a die cast housing. The bearing includes a shaft having two axially spaced inner races defined in it, an outer ring around and radially spaced from the inner ring with respective races defined in it, and rolling elements between the races. A respective seal axially outward of each of the rows of rolling elements defines an enclosed sealed space between the seals. A housing is die cast around the outer ring. For providing heat protection during casting of the housing around the outer ring, a respective sheet metal jacket is placed around the outer ring in the axial regions covering the respective set of races and the adjacent seal, wherein the jacket is around the bearing during die casting of the housing thereon.
