A bearing cage for large rolling-element bearings includes a first side part and a second side part and a plurality of bridge elements connecting the first and second side parts to form a plurality of cage pockets each configured to receive a rolling element. The at least one bridge element and/or the first side part and/or the second side part includes at least one opening, and an insert element is mounted in each of the at least one opening and configured to contact the rolling element.

Bearing cage

A single-pocket cage segment of a multipart rolling-element bearing cage includes first and second side walls connected by first and second end walls. At least one of the first and second side walls or at least one of the first and second end walls is a semi-finished profile. The semi-finished profile may include a longitudinal channel in which a portion of an auxiliary body and/or a portion of a connector may be inserted.

Cage segment for a rolling-element bearing cage

A bearing cage segment for a segmented bearing cage includes a plurality of walls that define a pocket configured to receive a rolling element and an insert element captively retained in an opening in a first one of the plurality of walls. The insert element may be configured to guide a rolling element retained in the bearing cage and/or be configured as a lubricant reservoir.

A method includes separating a strip of sheet metal from a sheet metal body by a combination of punching and laser cutting, the strip having a first joint edge having at least one first alignment element and a second joint edge having at least one second alignment element complementary to the at least one first alignment element, folding a longitudinal edge portion of the strip to form a flange, bending the strip into a ring and materially bonding the first joint edge to the second joint edge, installing the ring on a radially inner circumferential surface or a radially outer circumferential surface and mounting a plurality of rolling-elements on the ring. The first joint edge and the second joint edge are formed by the punching, and side edges connecting the first joint edge and the second joint edge are formed by the laser cutting.
