Abstract

A roller bearing comprises at least two rows of rollers disposed between an inner ring and an outer ring. At least two tracks guide the respective rows of roller and are defined in the axial direction of the inner ring or the outer ring. At least one flange abuts axial ends of axially-adjacent rows of rollers and extends radially from a radially outer side or a radially inner side of the inner ring or the outer ring. At least one recess is defined on the side of the inner ring or the outer ring that is opposite of the radially outer side or the radially inner side of the inner ring or the outer ring, from which the at least one flange radially extends. The at least one recess at least partially overlaps the at least one flange in the axial direction.
