Abstract
A thrust bearing has an outer race and an inner race arranged for rotation relative to the outer race about an axis of rotation. Multiple rolling elements are positioned between the inner and outer races. A cage is positioned between the inner and outer races and configured to engage with the rolling elements to align the rolling elements into multiple rows, with the rows circumferentially spaced apart from one another.

A thrust bearing comprising:
- a first race;
- a second race positioned opposite the first race, wherein the second race is arranged for rotation relative to the first race about an axis of rotation;
- a plurality of rolling elements positioned between the first race and the second race;
- and
- a cage positioned between the first race and the second race and configured to engage with the rolling elements to align the rolling elements into a plurality of rows, the rows circumferentially spaced apart from one another, wherein each row of rolling elements extends linearly along an axis that is offset from the axis of rotation;
- wherein each row of rolling elements includes at least two rolling elements;
- and
- wherein the cage includes a body and a plurality of pockets formed into the body, and wherein the pockets are configured to receive the rolling elements and engage with the rolling elements to align the rolling elements into the rows, and wherein each pocket defines an opening through the body of the cage that is sized to receive at least two rolling elements.
