High-speed bearing

A cage for use with a roller bearing, the cage comprising:

• an inner rim;
• a plurality of webs extending radially outboard from the inner rim and being circumferentially arranged around the inner rim to be spaced apart to define pockets configured to receive roller elements, the webs having flanges that extend axially, wherein portions of the inner rim disposed between the webs forms inner guide surfaces of the pockets;
• a wavy outer rim circumscribing the inner rim, the outer rim having radially outer portions attached to the flanges and radially inner portions forming outer guide surfaces of the pockets;
• and
• a plurality of cutouts, each extending radially through a thickness of the outer rim, defined between an adjacent pair of the flanges, and forming a radial back surface of the outer rim that extends circumferentially between the adjacent flanges, wherein the radial back surfaces of the outer rim are axially forward of a back surface of the inner rim to form a discontinuous backside of the cage.

A roller bearing comprising:

• a first race;
• a second race;
• a cage disposed between the first and second races, the cage including:
• an inner rim having a back surface,
• an outer rim having a back surface and circumscribing the inner rim such that the back surface of the outer rim is forward of the back surface of the inner rim, and
• a plurality of radially extending webs circumferentially arranged around the inner rim and spaced apart to define pockets, each of the webs having an axially extending flange connected to the back surface of the outer rim, wherein the outer rim and the flanges cooperate to define a plurality of cutouts circumferentially aligned with the pockets and forming a discontinuous back side of the cage, each of the cutouts being defined between an adjacent pair of the flanges and an associated portion of the back surface of the outer rim;
• and
• cylindrical roller elements disposed in the pockets between the first and second races and having first ends adjacent the inner rim and second ends adjacent the outer rim, wherein the roller elements are disposed in the pockets such that the cutouts expose the second ends to prevent contact between a perimeter portion of the roller elements and the outer rim.
