Abstract
A multi-row rolling-element bearing includes first and second bearing rings and first and second rows of rolling elements therebetween. A cage between the first and second bearing rings has a first annular side part having a plurality of axially extending first bridge elements and a second annular side part having a plurality of axially extending second bridge elements connected to the first bridge elements to form bridges and to form pockets therebetween. At least one rolling element of the first row of rolling elements and at least one rolling element of the second row of rolling elements are located in each of the plurality of pockets.

A multi-row rolling-element bearing comprising:
- a first bearing ring,
- a second bearing ring,
- a first row of rolling elements disposed between the first bearing ring and the second bearing ring and a second row of rolling elements disposed between the first bearing ring and the second bearing ring, and
- a cage including an first annular side part having a plurality of axially extending first bridge elements and a second annular side part having a plurality of axially extending second bridge elements,
- wherein the plurality of first bridge elements are connected to the plurality of second bridge elements at a plurality of joints to form a plurality of bridges and a plurality of pockets, each of the plurality of pockets being defined by an adjacent pair of the bridges,
- wherein at least one rolling element of the first row of rolling elements and at least one rolling element of the second row of rolling elements are located in each of the plurality of pockets, and
- wherein each of the plurality of pockets includes a plurality of rolling elements of the first row of rolling elements and a plurality of rolling elements of the second row of rolling elements.
A multi-row rolling-element bearing comprising:
- a first bearing ring,
