A roller bearing includes an outer ring, an inner ring, at least one row of rollers arranged between the outer ring and the inner ring, and at least one optical fiber cable mounted to the outer ring or the inner ring, the optical fiber cable including at least one Bragg grating. The optical fiber cable is configured such that a signal in the optical fiber cable is usable to determine a preload or load on the roller bearing.

A sealing arrangement for a wheel bearing having a first bearing part and a second bearing part integrally connected to a wheel bearing flange, and rolling bodies being guided between said bearing parts, includes a carrier element and a stop part. The carrier element is connected to the first bearing part, an elastic element is provided on the carrier element, and the carrier element has a fastening section connected to the first bearing part. The elastic element has a sealing lip. The stop part is fastened to the second bearing part and in sliding contact with the sealing lip. The wheel bearing flange has an axial projection provided such that the projection protrudes in the direction of a cavity formed by an axial projection of the first bearing part. An inner surface of the axial projection of the wheel bearing flange forms a seat for the stop part.

A gondola of a Ferris wheel installation is connected to a wheel rim structure of the Ferris wheel by means of a guide structure comprising at least one bearing that is connected to the wheel rim structure by two sliding ball joints which have slide axes that are parallel to one another and spaced apart from one another.

A method for installing a bearing assembly on a stationary component where the bearing assembly includes a bearing carrier, a stationary bearing ring rotationally secured to the bearing carrier and a rotatable bearing ring supported for rotation relative to the first bearing ring. The method includes inserting a portion of the bearing carrier into an opening in the stationary component or inserting a portion of the stationary component into the bearing carrier, using an alignment tool to position at least two exposed radial surface portions of the stationary bearing ring with a surface of the stationary component to produce a temporary alignment of a rotational axis of the stationary bearing ring with a central axis of the stationary component, after producing the temporary alignment, attaching the bearing carrier to the stationary component in a manner that maintains the alignment, and removing the alignment tool from the bearing ring.

A bearing assembly includes a bearing unit formed from a stationary bearing ring configured to be connected to a stationary component and a rotatable bearing ring configured to be connected to a rotatable component and a bearing carrier connected to the stationary bearing ring in a rotationally fixed manner, for example, by overmolding. The bearing carrier includes at least one notch that exposes at least one section of the stationary bearing ring.

A sensor bearing housing assembly for use with or integrally formed with a bearing housing. The bearing housing having a base portion defining a footprint, a shaft receiving collar, and a bearing race disposed between the shaft receiving collar and the bearing housing. The sensor bearing housing assembly having a pair of lengthwise sidewalls configured to extend upward from the base portion and an endwise sidewall configured to extend upward from the base portion. The pair of lengthwise sidewalls and the endwise sidewall being joined to form a sensor volume for receiving a sensor therein generally defined within a vertical volume bounded by the footprint of the base portion. The sensor bearing housing assembly having a cutout formed in at least one of the pair of lengthwise sidewalls and the pair of endwise sidewall to permit access to a fastener extending through a mounting hole formed in the base portion.

A bearing ring has first and second cylindrical surfaces, first and second annular side surfaces and at least one compensation element attached to the bearing ring, preferably in a groove at a junction of the first cylindrical surface and the first annular side surface. The bearing ring is manufactured from a first material having a first coefficient of thermal expansion and is configured to be connected to a component that is manufactured from a second material having a second coefficient of thermal expansion, and the at least one compensation element is manufactured from a third material having a coefficient of thermal expansion that is greater than or equal to the coefficient of thermal expansion of the second material. Also a bearing assembly including the bearing ring and the component.

A hover-capable aircraft is described that comprises a drive unit, a rotor and a transmission interposed between the drive unit and the rotor; the transmission comprises a gear; the gear, in turn, comprises a main body rotatable about a first axis and a plurality of first teeth projecting in a cantilever fashion from the main body; the gear comprises a first pair of first rings axially opposite to each other and cooperating with the gear so as to exert a radial force on the gear.

A motor adjustment drive for a vehicle steering column includes a threaded spindle with an axis. The threaded spindle engages a spindle nut. A drive unit and a gear wheel which is connected to the spindle nut or the threaded spindle for rotation therewith is driveable to rotate by the drive unit and is rotatably mounted in a bearing housing between two outer bearing rings that are axially supported at the bearing housing. The outer bearing rings each have, on their sides facing one another, a circumferential outer bearing face that is coaxial to the axis. Each outer bearing face lays opposite a bearing face embodied on the end side at the gear wheel. An outer bearing ring is axially resiliently supported at the bearing housing via an elastic element, which exerts an axial force that biases the two outer bearing rings toward each other.
