A rolling-element bearing includes first and second rings having axial and radial raceways and a row of first radial rolling elements between the axial raceways. At least one row of axial rolling elements is located between a first radial raceway of the first ring and a first radial raceway of the second ring and radially located between an axial guiding face of the first ring and an axial guiding face of the second ring. The axial rolling elements are mounted in the pockets of a cage having a plurality of cage segments, and at least one second radial rolling element is circumferentially interposed between two adjacent cage segments of the plurality of cage segments and radially interposed between the axial guiding faces.

A cage segment is for a rolling-element bearing cage, particularly for large rolling-element bearings. The cage segment includes a first side element and a second side element that are connected by a first bridge and a second bridge. At least one pocket is formed between the first and second bridges which is suitable for receiving at least one rolling element. The cage segment is manufactured from sheet metal.

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.

The cage segment for rolling bearing has a main body provided with at least two pockets each configured to receive at least a roller, with two opposite cylindrical faces extending circumferentially and delimiting radially the cage segment, and with two opposite frontal faces delimiting axially the cage segment. The cage segment further provides a first group of protruding means affixed to the main body and protruding relative to the cylindrical faces, and a second group of protruding means affixed to the main body and protruding relative to the frontal faces.

Disclosed is an axial-radial rolling bearing having an inner ring, an outer ring disposed around the inner ring, and a plurality of rolling bodies in the form of rollers arranged into at least one row disposed between and separating the inner ring and the outer ring. The rolling bearing further includes at least one rolling bearing cage disposed around at least part of the rollers and configured to maintain a predetermined spacing of each of the rollers from each adjacent roller in the at least one row, wherein the rolling bearing cage comprises a plastic coated main body that is at least one of ring-shaped or segmented. The main body has openings for receiving the respective rolling elements.

A cage segment of a rolling bearing, which cage segment has two side plates and two webs which are fixedly connected to one another, wherein the webs extend parallel to the axis of rotation of the rolling bodies of the rolling bearing, and in which cage segment the side plates and the webs form a pocket for receiving a rolling body. In order to be able to produce and assemble a cage segment of said type in an inexpensive manner, and in order to be able to ensure operation without jamming in an associated rolling bearing, it is provided that the two side plates on both sides of the pocket extend in a circumferential direction of the rolling bearing to such an extent that the side plates together with in each case one of the two webs form in each case one half-pocket for receiving a directly adjacent rolling body.

A tapered roller bearing (31a) has a plurality of retainer segments (11a, 11d) each having a pocket to house a tapered roller (34a), and arranged so as to be continuously lined with each other in a circumferential direction between an outer ring (32a) and an inner ring (33a). The retainer segment (11a, 11d) is formed of a resin containing a filler material to lower a thermal linear expansion coefficient. In addition, a clearance (39a) is provided between the first retainer segment (11a) and the last retainer segment (11d) after the plurality of retainer segments (11a, 11d) have been arranged in the circumferential direction without providing any clearance. Here a circumferential range (R) of the clearance (39a) is larger than 0.075% of a circumference of a circle passing through a center of the retainer segment (11a, 11d) and smaller than 0.12% thereof at room temperature.

The invention provides a cage for a bearing. The invention further provides the bearing and a method of producing the cage. The cage includes a plurality of pockets at least partially surrounding the rolling elements. The cage further comprises a first material and a second material. The first material is a first printed material printed via an additive manufacturing process that has different properties compared to the second material. The first material is printed in the pockets at a position where, the rolling elements at least occasionally contact the pockets. Using such first printed material allows application of the first printed material at a location where it is needed.

A cage segment for a bearing rotatable around an axis being able to receive a plurality of rolling elements configured to travel on two annular raceways respectively on inner and outer rings of the bearing, and including an inner wall that extends circumferentially in the form of a cylinder, the axis of symmetry being the axis (X1), an outer wall that extends circumferentially in the form of a cylinder, the axis of symmetry being the axis (X1), two end portions that are circumferentially opposed, which extend radially with respect to the axis (X1) and which connect together the inner wall and the outer wall, a plurality of successive pockets for receiving the rolling elements, so that two successive pockets are circumferentially delimitated by a radial beam, The radial beam extending radially with respect to the axis (X1), the radial beam comprising two end portions so that one end portion connects with the inner wall and the other end portion connects with the outer wall, The radial beam provides a first recess that extends axially with respect to the axis (X1).

A segmented cage for a bearing is provided. The segmented cage provides at least two successive segments each being able to receive at least one rolling element. These segments have inner and outer circumferential faces and adjacent end faces abutting circumferentially one on the other. The adjacent end faces are shaped to obtain only one contact line or contact point between them, the contact point or contact line being distant from the inner and outer circumferential faces.
