A bearing retainer for use in a bearing is provided. The bearing includes an inner ring, rolling elements and an outer ring. The bearing retainer includes a body. The body defines an inner periphery and an outer periphery of the body. The body further defines a plurality of inner walls. Each inner wall defines an opening extending from the inner periphery to the outer periphery of the body. The plurality of openings are adapted to receive one of the rolling elements. The inner walls are adapted to keep the rolling elements in a spaced apart relationship. At least one of the inner walls defines a aperture through the body. The aperture is adapted for storing lubrication therein.

A bearing cage for large rolling-element bearings includes a first side part and a second side part and a plurality of bridge elements connecting the first and second side parts to form a plurality of cage pockets each configured to receive a rolling element. The at least one bridge element and/or the first side part and/or the second side part includes at least one opening, and an insert element is mounted in each of the at least one opening and configured to contact the rolling element.

A bearing cage assembly including two different cage halves formed from different materials is disclosed. The first cage half includes a first rim and a first plurality of arms extending from the first rim. The second cage half includes a second rim and a second plurality of arms extending from the second rim. The first cage half and the second cage half are fastened to each other via engagement between a plurality of first retainers of the first cage half with the plurality of second retainers of the second cage half.

A cage for a thrust roller bearing is provided. The cage has first and second cage members each having an outer ring portion formed radially outside of a roller retention hole. The outer ring portion has a flange portion that extends, from a radially outer end of the outer ring portion, in an axial direction and is divided along the circumferential direction. The flange portion has a large diameter portion and a small diameter portion. The first cage member and the second cage member are fastened to each other while the large diameter portion and small diameter portion of the first cage member overlap the small diameter portion and large diameter portion of the second cage member, respectively.

A radial roller bearing can include an outer race having as a center axis a first axis extending in a first direction and an inner race having as the center axis the first axis. A group of rollers composed of a plurality of rollers arranged at intervals in the circumferential direction can be centered on the first axis between the outer raceway surface of the outer race and the inner raceway surface of the inner race and a cage can be provided for holding the group of rollers. A first regulating part can be provided for regulating the movement of the outer race to one side. A second regulating part can be provided for regulating the movement of the outer race to another side. The first regulating part and the second regulating part can be arranged at positions at which the distance between the first regulating part and the second regulating part is a prescribed distance longer than the outer race.

The present invention has an outer race having as a center axis a first axis extending in a first direction; an inner race having as the center axis the first axis; a group of rollers composed of a plurality of rollers arranged at intervals in the circumferential direction centered on the first axis between the outer raceway surface of the outer race and the inner raceway surface of the inner race; a cage for holding the group of rollers; a first regulating part for regulating the movement of the outer race to one side; and a second regulating part for regulating the movement of the outer race to another side. The first regulating part and the second regulating part are arranged at positions at which the distance between the first regulating part and the second regulating part is a prescribed distance longer than the outer race.

A snap-action cage for a tapered roller bearing is configured as a window cage with a plurality of windows for receiving tapered rollers, with a first cage portion having a plurality of first web portions. The first web portions in each case define run-on surfaces for the tapered rollers. A second cage portion has a plurality of second web portions that are connectable and/or are connected to the first web portions via a snap-action connection, in order to form in each case one web. The second web portions are configured spaced apart in the circulating direction from and/or without contact with the run-on surfaces. The hook receptacle has a fork hook with a hook groove which is configured in between, and the snap-action hook snaps into the fork hook, and a guide portion is held in the hook groove in a positively locking manner in the circulating direction.
