A radial support bearing having a cylindrical cage including a central portion, a first end portion and a second end portion, the central portion defining a plurality of roller pockets, and at least one projection extending radially inwardly from an inner surface of the cage, a plurality of rollers, each roller being disposed in a respective roller pocket, a cylindrical outer sleeve disposed about an outer surface of the cage so that the inner surface of the outer sleeve is adjacent the plurality of rollers, and an o-ring adapted to be axially fixed relative to the shaft. The o-ring is slidably received between the at least one projection of the cage and the central portion of the cage so that the cage is axially fixed with respect to the shaft.

A cage segment for a rolling-element bearing having a plurality of rolling elements includes at least one bridge and first and second plates extending from axial ends of the bridge, sides of the bridge being configured to guide rolling elements. Radially inner or outer edges of each of the bridges include at least one axial channel having channel walls projecting radially and circumferentially from the radial inner or outer edge.

An axial bearing is designed to work in a liner hangar in which radial package space is at a premium. Rollers axially separate two washers. To hold the bearing together prior to installation, a sleeve radially surrounds the rollers and has tabs which fit into circumferential grooves in the washers. The sleeve may be metal or plastic.

An assembly tool for a bearing ring having roller members, the tool including a ring configured to be arranged on a side face of the bearing ring and including sliding elements received in receiving members on the ring. The sliding elements are distributed peripherally in a uniform manner around the ring and are configured to be displaced from a starting position into an end position relative to the ring. When the tool is mounted on the ring, the sliding elements, positioned in their end positions, extend between adjacent roller members and limit a radial movability of the roller members relative to the bearing ring.

Provided is a transport jig to be packed together with a double-row self-aligning roller bearing having an intermediate flange when the double-row self-aligning roller bearing is transported. The transport jig is formed in a ring shape having inner and outer diameters that allow the transport jig to be radially accommodated between an outer circumferential surface of an end portion of an inner ring and an inner circumferential surface of an end portion of an outer ring of the double-row self-aligning roller bearing, has a shape such that one side surface of the transport jig comes into contact with an end surface of each rolling element of the double-row self-aligning roller bearing and another side surface of the transport jig protrudes beyond end surfaces of the inner and outer rings, and is formed from a material softer than the rolling elements.

An installation tool for a bearing ring including rolling elements includes a ring that is configured to be disposed on a lateral surface of the bearing ring and slider elements extending through receptacles in the ring. The slider elements are uniformly distributed circumferentially around the ring and are displaceable relative to the ring from an initial position into an end position and are configured to be disposed in the end position between two rolling elements and against a contact surface of a wall of a cage segment, which wall is disposed between two rolling elements, in order to limit axial and radial movement of the rolling elements relative to the bearing ring.
