摘要： A method of producing rolling elements for a rolling bearing comprises mixing to process rounded elements made of steel balls and spherical rolling elements having outer diameter portion portion becoming a rolling contact face. The rolling contact face has curvatures in an axial direction and a radial direction normal to the axial direction, and has at least one plane. The thus mixed elements are placed and processed in a space between two processing boards opposing each other via the determined space. Thereby, the surfaces of the rounded balls and the rolling elements are processed to be rounded.

摘要： The invention relates to a bearing cage (1) for receiving rolling elements (6). In addition to two rings (2, 3), the bearing cage also has a plurality of webs (4) which run axially between the rings (2, 3). In order to prevent the rolling elements (6) from falling out of the pockets (5) formed between the rings (2, 3) and the webs (4), the webs (4) are at least provided with a groove (7a) which runs in the direction of the respective web (4). When the rolling elements (6) are inserted into the pockets (5), a tool (9) engages into the groove (7a) and bends the edge region (11) of the web (4) in a direction of the rolling elements (6) inserted into the pockets (5).

摘要： A rolling-element bearing cage includes a plurality of cage segments, each cage segment including at least two adjacent receiving pockets, each receiving pocket being delimited by a front cage bridge having a front running surface for contacting a rolling element and a rear cage bridge having a rear running surface for contacting the rolling element. The front running surface and the rear running surface of at least one of the at least two adjacent receiving pockets are asymmetric relative to a center plane that divides the receiving pocket.
