1. A roller bearing comprising:
an inner ring;
an outer ring; and
a plurality of rolling bodies configured to roll in two rows on corresponding raceways on the inner ring and on the outer ring, wherein the outer ring is split radially to form at least two ring portions, wherein the raceway in an abutment region between the at least two ring portions has a ground recess locally deepening the raceway, and wherein the ground recess has an arcuate course extending transversely to the abutment region, the greatest radial depth of the ground recess lies in the abutment region, and the 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 a contact point of a first rolling body and a contact point of a second rolling body that, due to a third rolling body disposed circumferentially between the first and second rolling bodies, is next but one in relation to the first rolling body with the raceway and which is greater than half the diameter of the first rolling body at the point of its greatest diameter, and wherein at least one fitting screw is provided in the abutment region of the at least two ring portions which connects the at least two ring portions, wherein the abutment region between the at least two ring portions intersects an unthreaded shaft portion of the at least one fitting screw.
 
10. A roller bearing comprising:
a first ring that is split to form at least two first ring portions;
a second ring; and
a plurality of rolling bodies configured to roll in first and second rows on corresponding first and second raceways on the first and second rings, wherein a portion of the first raceway encompassing a first abutment region between the at least two first ring portions includes a first recess defined by the first ring that locally deepens the first raceway, wherein the first recess has an arcuate course extending transversely relative to the first abutment region, the greatest radial depth of the first recess lies at the first abutment region, and the first recess extends in the circumferential direction of the first raceway of the first ring, at least half the diameter of the rolling body at the point of its greatest diameter, and wherein the second ring is split to form at least two second ring portions, and at least one fitting screw is provided in one of (1) the first abutment region between the first ring portions, and (2) a second abutment region between the second ring portions, wherein the at least one of the first abutment region and the second abutment region intersects an unthreaded shaft portion of the at least one fitting screw.
