摘要: A separator 8 including a solid lubricant is disposed between adjacent rolling elements 7. Relative movement of the adjacent rolling elements 7 and the separator 8 in a direction of separating apart in a circumferential direction is restricted by restricting members 10, and the restricting members 10 are disposed at plural locations in the circumferential direction. A minute gap α is provided between the adjacent restricting members 10, to allow relative movement therebetween. This can provide a solid-lubrication rolling bearing capable of stably preventing rotational locking and unintended disassembling of the bearing for a long period.

摘要: An object of the present invention to provide a rolling bearing which is capable of preventing the rolling elements from dropping out from between the inner and the outer rings even when the separators have been worn to an advanced stage. A rolling bearing includes: a plurality of rolling elements 3 arranged between an inner and an outer rings 1, 2; and a plurality of prismatic separators 4 disposed in a circumferential direction between the rolling elements 3. The separator 4 includes integrally therewith a metal band 6 on at least one of its outer surfaces including those which face the inner or the outer ring 1 or 2, or at least one of its axial side surfaces, excluding however, surfaces which face the circumferential direction and make contact with the rolling elements 3. The metal band 6 has a narrower width than a width of the separator 4 in the circumferential direction, and prevents wear of the separator 4 from advancing beyond a certain extent.

摘要: A double row thrust roller bearing includes a pair of inner and outer cages (220,320) arranged radially in two rows in separate coaxial relation, each cage including an annular inner peripheral wall (241,341), an annular outer peripheral wall (251,351), a plurality of pillar portions (230,330) interconnecting the annular inner and outer peripheral walls at intervals in a circumferential direction thereof, and a plurality of pockets (231,331) each formed between the adjacent pillar portions. Rollers (10) are rotatably held and retained respectively in the pockets. The annular inner peripheral wall (241) of the inner cage is guided by an annular flange (61) formed at an inner peripheral edge of one race (60), and the annular inner peripheral wall of the outer cage (341) is guided at an inner periphery (341a) thereof by the annular outer peripheral wall (251) of the inner cage (220).
