Abstract

A roller bearing includes an outer ring having a substantially cylindrical internal bearing surface and an outside surface defining a plurality of protuberances. A protective coating is applied to the outside surface of the outer ring. An inner ring is coaxially disposed at least partially in the outer ring and has a substantially cylindrical external bearing surface. The external bearing surface and the internal bearing surface define an annular cavity in which a plurality of rolling elements is disposed. The rolling elements are in rolling engagement with the external bearing surface and the internal bearing surface. The outside surface of the outer ring can be case hardened, for example the outer ring can be carburized. The outside surface of the outer ring can be knurled. A method of manufacturing such a bearing is also disclosed.
