摘要： A cage segment for a segmented bearing cage includes first and second end walls configured to oppose first and second end surfaces of a rolling element and a first side wall and a second side wall extending from the first end wall to the second end wall and defining with the first and second end walls end a pocket for receiving the rolling element. The first and second side walls are configured to oppose a curved side surface of the rolling element. The first and/or second end wall includes at least one protrusion extending into the pocket that is configured to contact an end surface of the rolling element. Also an assembly of the cage segment and the rolling element.

摘要： A bearing raceway element configured as an inner ring or as an outer ring, or configured to be attachable to an element serving as an inner ring or as an outer ring for the bearing or to an inner ring or an outer ring of the bearing. The raceway element is manufactured from a sheet metal panel and includes at least one first joint edge and at least one second joint edge directed in the circumferential direction that are configured to be connected to each other in order to form an annular raceway element. The at least one first joint edge is at least partially configured as a first alignment element and/or includes the first alignment element. Also a bearing including the raceway element and an associated method.

摘要： A sheet metal bearing cage segment includes a first ring section, at least one second ring section, and a plurality of bridges connecting the first and second ring sections to each other and defining a plurality of pockets between the bridges. The bearing cage segment includes first and second circumferentially directed joint edges, the first joint edge is configured to connect to the second joint edge of the bearing cage segment or to a second joint edge of another sheet metal bearing cage segment, and the first joint edge includes at least one body of welding material projecting from the joint edge. The body of welding material may be pressed against the second joint edge while leaving a gap between the joint edges, and the welding material can be liquified by a resistance welding process to connect the joint edges.

摘要： A bearing support is configured to retain at least two bearings disposed closely adjacent to each other in a parallel relationship. Each bearing includes a bearing outer ring having a cylindrical outer circumferential surface. A support part includes a recess configured to hold the at least two bearings. At least one junction portion is defined in the support part adjacent portions of the cylindrical circumferential surfaces of the bearings that are not filled by the bearings when the bearings are inserted into the support part. The support part is connected with a cover part that axially abuts on the bearings. The cover part includes at least one support element that extends into the junction portion between the bearings in the assembled state of the bearing support and at least partially fills the junction portion.

摘要： 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.
