摘要： A thrust roller bearing cage (11) of the present invention is included in a thrust roller bearing (20) and includes a plurality of pockets (21) accommodating rollers (13). The thrust roller bearing cage (11) includes: a radially outer area bent portion (41) formed by bending an area located radially outside the pockets (21) inward in a radial direction; and projecting portions (44) that are formed in a tip end of the radially outer area bent portion (41) and project inward in the radial direction so as to contact end faces (16) of the rollers (13) accommodated in the pockets. Radially outer edges (21a) of the pockets (21) are located radially outside base end parts (44a) of the projecting portions (44).

摘要： A roller bearing cage includes ring portions and pillar portions extend in an axial direction to connect the ring portions and disposed along a circumferential direction to define pocket portions. The pillar portion includes a bent portion formed in the vicinity of an axial center of the pillar portion so as to protrude radially inwards of the ring portions. A ring portion thickness is larger than a bent portion thickness; a pillar end portion thickness is larger than the bent portion thickness; and the pillar end portion thickness is equal to the ring, portion thickness or more, where the ring portion thickness is a radial thickness of the ring portion; the bent portion thickness is a radial thickness of the bent portion; and the pillar end portion thickness is a thickness of a portion of the pillar portion connected to the ring portion and in the vicinity thereof.

摘要： A radial cage in which side rings have a material thickness of a starting material for the radial cage, straight side sections of each axial crossbar are implemented with a greater material thickness that increases their strength, and an axial center section of each axial crossbar is implemented with a smaller material thickness than the material thickness of the side rings, thus reducing centrifugal mass.

摘要： The bearing cage for roller bearings has an inner ring, an outer ring, and a plurality of cage bars extending between the inner ring and the outer ring so as to form a plurality of pockets. At least one of the inner ring and the outer ring has a formed ring flange protruding inwardly into the pockets. The pockets have of least one curved end with a radius or a straight end with large radii so that the pockets extend under the ring flange. The formed ring flange provides radial guidance to the ends of the rolling elements, which also aids in reducing the possibilities of stress risers from forming, causing fatigue and ultimately failure of the bearing cage.

摘要： A flat strip of metal is formed to provide a depressed center relief portion between two edge portions. Depressions are formed in the two edge portions and center slots are pierced across the center relief portion such that roller receiving slots are formed with slot end depressions at both ends of the roller receiving slots. The partially formed bearing cage is then formed into a circular hoop such that the edge portions form rings at the axial ends of the circular hoop. The resulting roller bearing cage of the present invention may also be formed by other methods.
