The bearing provides an outer ring and an inner ring capable of rotating concentrically relative to one another. At least one of the inner and outer rings are split into a plurality of successive circumferential ring segments. Each pair of adjacent successive ring segments of the split-ring is secured together with at least one fixing plate. The fixing plate is disposed inside a first groove disposed on one of the ring segments and a second groove 38 disposed on the other ring segment. The fixing plate is set back or flush with at least the surface of each of the ring segments from which the first or second groove is formed.

A rolling bearing includes first and second rings each having an axial raceway and a radial raceway and axial rolling elements between the radial raceways and radial rolling elements between the axial raceways, the second ring having a protruding nose extending into an annular groove of the first ring, the nose having an axial cylindrical surface that forms the axial raceway of the second ring. Also at least one ultrasonic distance sensor mounted on the first ring in radial contact with the axial cylindrical surface of the nose and configured to emit radiation in a main radiation direction oriented towards a surface of the second ring that is inclined relative to a rotation axis of the rolling bearing.

An open-centered large rolling bearing having two concentric bearing rings, which are supported against one another in the axial direction of the rolling bearing by means of at least two axial bearings, which are arranged on opposite end faces of a bearing ring. In the radial direction, the bearing rings are supported against one another by at least three radial bearings, which are arranged on inner and outer circumferential sides of a bearing ring.

A rolling bearing provides an inner ring and an outer ring concentrically about a rotation axis X-X′ running in an axial direction, and at least first and second axial bearings each axially disposed between the inner ring and the outer ring and each having at least one row of rolling elements, the first and second axial bearings being spaced apart from each other in the axial direction. The rolling bearing further provides only one radial bearing radially disposed between the inner ring and the outer ring and having at least one row of rolling elements. The radial bearing is disposed between an outer raceway located on the inner ring and an inner raceway located on the outer ring.

The present disclosure relates to a bearing arrangement for supporting a shaft, in particular a shaft of a gearing mechanism for an electromechanical brake booster, having: at least one bearing, a shaft, which is at least section-wise accommodated in the at least one bearing and has a protruding, rounded region on at least one of its axial end surfaces, at least one spring element, that engages the protruding, rounded region in order to prestress the shaft in the axial direction.

A bearing arrangement may be employed in a rotor shaft of a wind turbine. The rotor shaft may transfer rotation of a hub with rotor blades to a generator. The bearing arrangement may include a hub-side rolling bearing and a generator-side rolling bearing. The hub-side rolling bearing may be configured as a radial roller bearing. The generator-side rolling bearing may be configured as a three-row roller rotary connection. The hub-side rolling bearing may include a closed cage with windows for guiding rolling elements. Rows of the closed cage may be separated by a central web. Further, at least one of the generator-side rolling bearing or the hub-side rolling bearing may comprise inductively hardened raceways.

Presented are multi-axis pivoting coupler joints for motorized vehicles, methods for making/using such coupler joints, and electric scooters with multi-axis pivoting coupler joints enabling multimodal scooter operation. A pivoting coupler joint includes first and second bearing assemblies each with a respective housing, respective inner and outer races concentric with each other and located in their respective housing, and a respective set of rolling elements rollably interposed between their respective inner and outer races. The first inner race of the first bearing assembly receives therethrough and circumscribes an axle shaft of a vehicle wheel. The second inner race attaches to a wheeled rider deck of the vehicle. The first and second bearing housings are joined together and angularly offset from each other. For some applications, the first bearing assembly includes a pair of longitudinally spaced needle roller bearings, and the second bearing assembly includes a pair of longitudinally spaced tapered bearings.

A cage segment for a rolling-element bearing includes at least two pockets each configured to receive at least one first roller, and two circumferentially opposite end portions delimiting the cage segment in a circumferential direction, where each end portion has a concave cylindrical abutment face configured to guide a second roller. Also a rolling element bearing including a plurality of the cage segments.

Provided is an electric actuator (1), including: a motor part (A); and a motion conversion mechanism part (B). The motion conversion mechanism part (B) includes: a ball screw shaft (33); and a ball screw nut (32), which is rotatably fitted to an outer periphery of the ball screw shaft (33), and is provided so as to be capable of transmitting torque with a rotor (24) of the motor part (A) rotatably supported through intermediation of a rolling bearing (27, 30). The ball screw shaft (33) advances toward one side in the axial direction or retreats toward another side in the axial direction in accordance with a rotation direction of the ball screw nut (32). In the electric actuator (1), a needle roller bearing (47) serving as a thrust bearing is arranged adjacent to the ball screw nut (32) on the another side in the axial direction.

A spindle device includes a cover member. The cover member has, formed therein, a gas flow path configured to flow a compressed gas for providing sealing between a chuck portion as a rotating member and the cover member and sealing between the chuck portion and the spindle housing. The gas flow path includes a first conduit configured to communicate the outside of the cover member and a second conduit configured to allow the first conduit to communicate with a gap between the chuck portion and the spindle housing, the second conduit being larger than the outlet of the first conduit. The outlet of the second conduit faces a surface of the spindle housing.
