The guide ring comprises two partial circumference ring segments which are arranged loosely between or adjacent one or each of the rows of rolling bodies and are held in form-locked manner in the spherical surface of the outer ring due to resilience of the ring segments. ## Claims ### Claim 1 An antifriction bearing comprising: an inner ring, an outer ring, the rings having opposing races; at least one row of rolling bodies between the rings and shaped for engaging and rolling along the races; a separator in the space between the races and separating the rolling bodies; at least one guide ring in the space between the inner and outer races and shaped to be guided on one of the ring races for guiding at least one of the rows of rolling bodies and the separator; the guide ring comprising at least two ring segments, each ring segment being of a length less than the entire circumference of the bearing and the segments being positioned in the bearing so as to not be entirely overlapping circumferentially; the ring segments being arranged loosely along at least one lateral side of the rolling bodies in the at least one row, and the ring segments being shaped and sized to be held in form locked manner to the surface of the one ring race. ### Claim 2 (depends on 1) The antifriction bearing of claim 1, wherein each ring segment is elastically deformable for mounting. ### Claim 3 (depends on 1) The antifriction bearing of claim 1, wherein the one race is curved inwardly toward the other race. ### Claim 4 (depends on 1) The antifriction bearing of claim 1, wherein the guide ring is shaped and normally self biased outwardly to engage the outer ring race. ### Claim 5 (depends on 4) The antifriction bearing of claim 4, wherein the ring segments snap into the outer race and the outer ring. ### Claim 6 (depends on 4) The antifriction bearing of claim 4, wherein the ring segments have opposite ends; the opposite ends of each of the ring segments are generally flattened and not rounded at the outer race. ### Claim 7 (depends on 4) The antifriction bearing of claim 4, wherein each of the ring segments has at least one bend point along its length at which the ring segment is more easily deformed than elsewhere along the ring segment. ### Claim 8 (depends on 7) The antifriction bearing of claim 7, wherein the bend point at the ring segment is defined by a reduced cross section region of the ring segment. ### Claim 9 (depends on 1) The antifriction bearing of claim 1, wherein each ring segment covers a circumferential angle of between about 160.degree. and 180.degree.. ### Claim 10 (depends on 9) The antifriction bearing of claim 9, wherein the respective ring segments are at least in part at different circumferential regions around the bearing rings. ### Claim 11 (depends on 1) The antifriction bearing of claim 1, wherein the respective ring segments are at least in part at different circumferential regions around the bearing rings. ### Claim 12 (depends on 11) The antifriction bearing of claim 11, wherein the ring segments extend around different non-overlapping circumferential regions of the bearing. ### Claim 13 (depends on 1) The antifriction bearing of claim 1, wherein the ring segments are made of hardened steel. ### Claim 14 (depends on 1) The antifriction bearing of claim 1, wherein the guide ring comprises two ring segments, arranged loosely alongside one of the rows of rolling bodies. ### Claim 15 An antifriction bearing comprising: an inner ring and an outer ring, the outer ring having a spherical curvature race, the inner ring having two neighboring respective spherical races defining two laterally neighboring rows around the inner ring; a respective row of spherical roller bearing rolling bodies between each of the inner ring races and the outer ring race and the rolling bodies engaging and rolling along the respective inner race and the outer race; a separator in the space between the inner and the outer races separating the rolling bodies; at least one guide ring in the space between the inner and outer races shaped and positioned to be guided on the outer ring race for guiding at least one of the rolling bodies and the separator; the guide ring comprising at least two ring segments, each ring segment being of a length less than the entire circumference of the bearing and the segment being positioned in the bearing so as to not be entirely overlapping circumferentially; the ring segments being arranged loosely along at least one lateral side of the rolling bodies in the at least one row, and the ring segments being shaped and sized to be held in form locked manner to the spherical curve surface of the outer race. ### Claim 16 (depends on 15) The antifriction bearing of claim 15, wherein the guide ring is disposed between the two rows of the rolling bodies. ### Claim 17 (depends on 16) The antifriction bearing of claim 16, wherein each ring segment is elastically deformable for mounting and the ring segments snap into the outer race and the outer ring.
