Two axially-spaced outer races are disposed within the housing, each about one of the inner races.

The rolling bodies are interposed between the two bearing raceways of the outer ring and the first and second bearing raceways.

A plurality of balls are in rolling contact with the raceways.

Roller elements are disposed between the inner and outer races.

The ball (4) has two annular raceways (22) which act as the inner raceways for the spherical rollers (5).

Raceways are located on the RCU.

A ball bearing includes an outer ring (50) having two outer raceways and an inner ring (52) having two inner raceways.

Forward and rearward bearing races (70F, 70R) are positioned between the inner bearing member and the bearing shaft.

According to the invention, at least one groove is provided in the raceway base of the inner ball raceways and/or in the raceway base of the outer ball raceways.

The housing (14) has two tapered raceways (58) which surround raceways (42) on cones (40) that are fitted to the hub (12).

At least one of said raceways (12) comprises one or more indentation areas (13) in relation to a standard shape of the raceways.

The bearing (6) has two sets of raceways (28, 40) that are oblique to the axis x, and in addition rolling elements (36) arranged in two rows between the sets of raceways (28, 40).

The shaft and the bearing housing each have raceways for rolling elements.

Ring —annular part of a radial rolling bearing incorporating one or more raceways (ISO 5593:1997).

The invention relates to a roller bearing (6) comprising bearing rings (5, 10), the rolling surfaces (7, 15) of which roll the rolling bodies (9).
