A cage segment for a rolling-element bearing cage includes first and second side elements connected by a bridge extending in a longitudinal direction. A first attaching element on the first side element extends away from the bridge in a first direction parallel to the longitudinal axis and a second attaching element on the second side element extends away from the bridge in a second direction parallel to the longitudinal axis. The first and second attaching elements are configured to receive a wire or cable for connecting the cage segments to other cage segments, and the first attaching element is offset from the longitudinal axis in a first direction by a first distance and the second attaching element is offset from the longitudinal axis in a second direction opposite the first direction by a second distance.

Cage segment for a rolling-element bearing cage

A rolling-element bearing cage includes a first side ring and a second side ring connected to the first side ring by a plurality of bridges defining a plurality of pockets configured to receive a rolling-element. The first side ring includes a joint at which the first side ring is configured to be opened to increase a diameter of the first side ring, and the first side ring and the second side ring and the plurality of bridges are made of steel and an outer diameter of the second side ring is greater than 500 mm.

Roller bearing cage and method for mounting a roller bearing cage

A bearing ring for a rolling-element bearing including an axially extending outer surface, two radially extending side surfaces, an inner surface configured to at least partially contact a rolling element and at least one radially extending recess in the inner surface that is configured to work together with a lifting tool to allow the bearing ring to be lifted by the lifting tool. Also a method of lifting a bearing ring having such a recess.

Bearing ring

A rolling bearing includes an inner ring, an outer ring, a plurality of rolling elements disposed between the inner ring and the outer ring, and a plurality of cage segments separating circumferentially adjacent ones of the plurality of rolling elements. Each of the cage segments has an axial bridge portion and side plates at axially opposite ends of the bridge portion, each of the side plates having a convex end and a concave end circumferentially spaced from the convex end. The convex end of a first one of the side plates contacts the concave end of a second one of the side plates.

Rolling-element bearing

A rolling-element bearing cage or cage element includes at least one axial bridge region having first and second guide surfaces, the first guide surface and the second guide surface each have a recessed region axially between first and second non-recessed regions, at least one V-shaped receiving space in a radial outer surface of the rolling-element bearing cage or cage element configured to receive lubricant, and first and second fluid channels extending from the at least one receiving space to the recessed regions of the first and second guide surfaces. The fluid channels have rectangular cross sections, are about as wide as a width of the recessed regions, and are angled at an acute angle to a radial direction, and the receiving space is approximately as wide as the recessed regions.

Rolling bearing cage or cage element

A cage segment for a rolling-element bearing has at least one pocket for a rolling element and is formed by a first segment part and a second segment part. The second segment part abuts the first segment part in an axial direction and is connected to the first segment part by an interference-fit or a friction-fit, or in a materially-bonded manner.
