ABSTRACT:
A bearing assembly for a shaft mounting in a bore of a housing which comprises an outer ring having two outer raceways for inner and outer rows of rolling elements. The outer ring includes a seating surface section seated in the through-bore and a radially outward-direction flange section, a cover having a contact surface of a ring-shaped flange for sealing off the roller bearing on the outside, and at least one oil bore in the outer ring between the two outer raceways. The oil bore extends radially from the outside toward the inside to a reservoir for the rolling elements to supply or carry away a lubricant to or from the reservoir. The outer ring also has a lateral surface section of a ring-shaped extension carrying the outside outer raceway. This lateral surface section is adjacent to the outside end surface of the flange section of the outer ring. The inner surface of a centering extension is tightly seated on the ring-shaped extension. This centering extension is adjacent to the outside surface of the ring-shaped flange of the cover and each oil bore is located between the outside end surface of the flange section and the lateral surface section on the circumference of the outer ring. Each of the oil bores opens at its radially outer end into a connecting channel between the flange section of the outer ring and the ring-shaped flange of the cover. This connecting channel extends in an essentially radial direction.
