The roller bearing is part of an arrangement of a radial and an axial bearing attached to a rotating shaft. The ball elements are accommodated between two parallel positioned inner rings (2a) and a single outer ring. The outer surfaces (5) of the inner rings (2a) are provided with a stepped surrounding groove (6), slightly inclined (9) and with a rounded upper edge (11). The inclined surface (9) can be used for attaching an extractor (8) when a ring (2a) has to be replaced. A sharp edge (17) located at the upper surface acts as a barrier for the lubricant.
