Abstract
A thrust bearing cage includes a piloting feature to radially locate a thrust bearing with respect to one of the shafts. Specifically, the bearing cage includes an axial extension at an outer diameter that extends beyond the rollers and around an outer diameter of end of the shaft. This feature permits elimination of a washer.
Claims15
A bearing comprising:
- a cage;
- and
- a plurality of rollers retained by the cage, wherein the cage includes an axial extension extending axially beyond the rollers, the axial extension being a piloting feature and having a constant inner and outer diameter about a circumference of the axial extension, and wherein the axial extension defines at least one hole to permit a flow of lubricant.
An assembly, comprising:
- a first shaft having a first axial end;
- a second shaft having a second axial end;
- a cage including an axial extension extending axially beyond the first axial end, the axial extension being a piloting feature and having a constant inner and outer diameter about a circumference of the axial extension;
- and
- a plurality of rollers retained by the cage and bearing against the first axial end and the second axial end;
- wherein the axial extension defines at least one hole to permit flow of lubricant.

A raceless axial bearing configured to be positioned between axial ends of first and second shafts, comprising:
- a cage including a plurality of pockets and an axial extension, the axial extension being a piloting feature and having a constant inner and outer diameter about a circumference of the axial extension;
- a plurality of rollers retained in the pockets;
- and
- wherein the axial extension extends axially beyond the rollers such that the bearing is self-piloting on a shaft end of one of the shafts and the rollers are adapted to directly contact the axial ends of the first and second shafts;
- and
- wherein the axial extension defines at least one hole to permit flow of lubricant.
