<p>A double split bearing comprises: a pair of half outer race pieces (3a,3b), each of which include a parting surface (4) and includes an inclined surface (6a,6b) that is radially and outwardly expanded an inner periphery surface thereof toward the inclined surface; a pair of half cage pieces (9a,9b) arranged at the inner periphery surfaces of the half outer race pieces (3a,3b), each of which is provided with a plurality of pockets (10) that accommodate rollers (7) and include roller retainers (11a,11b,12a,12b) for restricting a displacement amount of the rollers (7) in a radial direction. The roller retainers (12a,12b) are formed at the pockets (10) so as to satisfy condition A > B where A represent a height from a start point of the inclined surfaces (6a,6b) provided at the parting surfaces (4) of the half outer races pieces (3a,3b) to an end point of the parting surfaces (4) and B represent a projecting amount of the roller (7) from the outer periphery of the cage (8).
