A bearing device includes a rotational shaft; a first outer ring; a second outer ring; first balls; second balls disposed; and a C-spacer and a second spacer. α>δd is satisfied, where δd represents a difference between an inside diameter of the second spacer at an end portion on a second side and an outside diameter of a shaft outer circumferential face, and α represents a half of a difference between a diameter of a cylindrical face of the C-spacer on an outer circumferential side and a diameter of the cylindrical face of the C-spacer on an inner circumferential side.

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.

A vehicle may include a flutter resistant caster. The vehicle may include a frame, a drive wheel coupled to the frame, a caster housing coupled to the frame, a caster, a locking element, a first bearing, and a biasing element. The caster housing may include an opening. The caster may include a caster wheel and a caster stem extending through the opening in the caster housing. The caster stem may be configured to rotate relative to the caster housing. The locking element may be coupled to the caster stem. The first bearing may be coupled to the caster stem. The biasing element may be coupled to the caster stem. The biasing element may be configured to exert a force on the first bearing.

A generator module includes a housing arranged for mounting to a rear face of an internal combustion engine, a generator stator fixed in the housing, a generator rotor arranged radially inside of the generator stator, and a bearing arranged to support a radial inside of the generator rotor on the housing. The generator rotor may include a rotor carrier and a plurality of stacked plates secured to the rotor carrier. The bearing may be at least partially radially aligned with the plurality of stacked plates.

A main bearing assembly of a wind turbine includes at least one main bearing with a rotation axis and at least one bearing row in which a rotor shaft of the wind turbine is mounted. The main bearing assembly has at least one stationary bearing ring, a circulating bearing ring and rolling elements. A method of extending the service life or servicing the main bearing assembly includes rotating the stationary bearing ring about the rotation axis of the main bearing assembly. Alternatively, only a new stationary bearing ring, preferably with at least two bearing ring segments is installed instead of a damaged outer ring, in particular without further important bearing components such as the inner ring being exchanged.

A support ring assembly for a railway axle having a support ring configured to be inserted between a rolling bearing and a collar of the railway axle, the support ring having an annular seat, a surface of a radially inner side wall fitted with a radial clearance over the collar and an end wall that abuts against the collar, an annular insert fitted into the seat by means of an annular shield and having an elastomeric annular element having at least two annular protuberances that engage with the collar, the annular element configured to engage with the collar so as to occupy the radial clearance.

A bearing and a shaft locking system for a bearing are disclosed. The bearing includes an inner ring having an opening configured to receive a shaft. The bearing includes a sleeve. The sleeve has a circular bore and an eccentric outer geometry. The sleeve is configured to fit onto the inner ring. The bearing includes a collar. The collar has an eccentric inner geometry. The collar is configured to fit onto the sleeve. In a concentric position, the concentric outer geometry of the sleeve and the eccentric inner geometry of the collar are configured to be offset. In an eccentric position, rotated from the concentric position, the eccentric inner geometry of the collar is configured to force the sleeve onto the inner ring.
