Abstract
A roller bearing includes inner and outer rings, and a plurality of rolling bodies configured to roll in two rows on corresponding raceways on the inner and outer rings. At least one of the inner ring and outer ring is split radially to form at least two ring portions. The raceway in an abutment region between the at least two ring portions has a ground recess locally deepening the raceway. Each ground recess on the outer ring has an arcuate course extending transversely to the abutment region, the greatest radial depth of the ground recess lies in the abutment region, and each ground recess extends in the circumferential direction of the raceway of the outer ring over a length which is at most the circumferential distance between the contact point of a first rolling body and the contact point of a second rolling body.
