Abstract
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.

A cage segment for a rolling-element bearing having a plurality of rolling elements, the cage segment comprising:
- a first bridge and a second bridge each having a first end and a second end spaced in an axial direction and a first side and a second side spaced in a circumferential direction and an outer edge and an inner edge spaced in a radial direction, and
- a first plate extending perpendicularly from the first end of the first bridge to the first end of the second bridge and a second plate extending perpendicularly from the second end of the first bridge to the second end of the second bridge,
- wherein the first side of the first bridge is configured to contact a first rolling element of the plurality of rolling elements and the second side of the first bridge is configured to contact a second rolling element of the plurality of rolling elements and maintain a spacing between the first and second rolling elements,
- wherein the first side of the first bridge defines a first circumferential end of the cage segment and the second side of the second bridge defines a second circumferential end of the cage segment, and
- wherein the radial outer edge of the first bridge and the radial outer edge of the second bridge each include at least one axial channel having channel walls or wherein the radially inner edge of the first bridge and the radial inner edge of the second bridge each include at least one axial channel having channel walls.
A cage segment for a rolling-element bearing having a plurality of rollers, the cage segment comprising:
- a first bridge and a second bridge, each of the first and second bridges having a first end and a second end spaced in an axial direction and a first side and a second side spaced in a circumferential direction and an outer edge and an inner edge spaced in a radial direction, and
- a first plate connecting the first end of the first bridge to the first end of the second bridge and a second plate connecting the second end of the first bridge to the second end of the second bridge,
- wherein the first side of the first bridge defines a first circumferential end of the cage segment and the second side of the second bridge defines a second circumferential end of the cage segment,
- wherein the second side of the first bridge and the first side of the second bridge define a pocket for receiving one of the plurality of rollers,
- wherein each radial outer edge includes a pair of walls projecting radially and circumferentially from the radial outer edge, facing inner surfaces of each pair of walls defining a channel and outer surfaces of each pair of walls being
- curved to form guide surfaces for the plurality of rollers, and
- wherein bottoms of the channels are radially spaced from the outer edges of the cage segments.
