The invention relates to a rolling element bearing cage formed of one or more segments, each segment comprising: a supporting frame having a plurality of spaced apart openings each for accommodating a rolling element; and a reinforcing frame, inserted within the supporting frame, having a corresponding plurality of openings each for aligning with the openings of the supporting frame.

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 cage for a rolling bearing formed from two axial halves and a rolling bearing cage assembly including a cage formed from two axial halves, include passages formed through the web separating adjacent rolling element pockets when the two halves are in an abutting relationship. A resilient element is inserted in at least one passage with axial ends extending into the adjacent rolling element pockets.
