1. A bearing comprising an outer ring and an inner ring capable of rotating concentrically relative to one another, at least one of the inner and outer rings being split into a plurality of successive circumferential ring segments, wherein for each pair of facing ends of adjacent successive ring segments of the split-ring, one of the facing ends comprises at least one protrusion made in one part with the associated ring segment and protruding into a recess of complementary shape formed onto the other facing end to align the pair of facing ends in radial direction,
wherein the at least one protrusion comprises two flat trapezoidal leg faces extending outwardly from the facing end, the two flat trapezoidal leg faces delineating a flat outer face of the at least one protrusion, the flat outer face being parallel to the facing end,
wherein the width of each of the two flat trapezoidal leg faces is shorter than the width of the flat outer face, and
each pair of adjacent successive ring segments of the split-ring is secured together with at least one fixing plate, the fixing plate being disposed inside first and second grooves respectively provided on frontal faces of the ring segments, the fixing plate being set back or flush with at least the face of each of the ring segments from which the first or second groove is formed.
