Abstract
A cage for a ball bearing is optimized for high-speed applications. To reduce weight, the cage is formed by a number of conical blades which collectively form an “X” shape. To add rigidity, a number of gussets are placed between the blades at various circumferential locations. The light weight reduces the centrifugal forces for a given diameter and rotational speed. The rigidity permits the cage to withstand the centrifugal forces without excessive deflection or stress.

-9. (canceled)
A bearing comprising:
- a cage having four conical webs extending from a central region to create an X-shaped cross section, the webs having cutouts defining a plurality of roller pockets;
- and
- a plurality of balls retained in the plurality of roller pockets;
- wherein the four conical webs includes:
- a continuous outer conical web extending from the central region radially outward and axially toward a closed side of the roller pockets;
- a continuous inner conical web extending from the central region radially inward and axially toward the closed side of the roller pockets;
- a non-continuous outer conical web extending from the central region radially outward and axially toward an open side of the roller pockets, the non-continuous outer conical web including a first plurality of segments separated by the roller pockets;
- and
- a non-continuous inner conical web extending from the central region radially inward and axially toward the open side of the roller pockets, the non-continuous inner conical web including a second plurality of segments separated by the roller pockets.
