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 having concentric bearing rings supported on one another rotatably with respect to each other by means of at least one row of rolling elements and have bearing races for the rolling elements of the at least one row of rolling elements. The invention further relates to a material transfer- or construction machine, such as a crane or cable excavator, having such a rolling bearing. Providing different bearing race corrections in different angular sectors of the bearing rings and/or providing the bearing race correction only in a fraction of the circumference of the bearing rings is advantageous over the conventional use of a bearing race correction that is constant over the circumference. A bearing race correction that is limited to one sector or that is different from sector to sector, or that is not constant over the circumference, enables the bearing rings to adapt to expected loads.

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.

The bearing provides a first ring and a second ring capable of rotating concentrically relative to one another. At least first and second tapered grooves are formed on the second ring and are oriented towards the first ring. The bearing further provides at least one first distance sensor mounted on the first ring and facing a tapered wall of the first tapered groove of the second ring, and at least one second distance sensor mounted on the first ring and facing a tapered wall of the second tapered groove of the second ring, the tapered walls of the first and second grooves extending obliquely along two opposite directions.

The bearing provides a first ring and a second ring capable of rotating concentrically relative to one another, at least one annular groove being formed on the second ring and oriented towards the first ring. The bearing further provides a measuring system mounted on the first ring, at least one guideway, at least one sliding carriage mounted on the guideway and axially moveable relative to the guideway, at least one sensor to detect axial positions of the sliding carriage relative to the guideway, an abutting element attached on the sliding carriage and coming into contact with at least one wall of the groove of the second ring at least in the axial direction, and a pre-stressing element to maintain the contact between the abutting element and the wall of the groove.

A bearing provides a first ring and a second ring capable of rotating concentrically relative to one another, and at least one seal provided with at least one sealing lip. The bearing further includes a sealing module providing a carrier reversibly secured to the first ring, the seal being mounted radially into contact with the carrier, a friction ring reversibly secured to the second ring, the sealing lip of the seal coming into contact with the friction ring, and at least one spacing element axially interposed between the friction ring and the second ring.

A rolling bearing providing a first ring and a second ring capable of rotating concentrically relative to one another, at least one row of rolling elements arranged between first and second raceways of the first and second rings, and at least one seal provided with at least one sealing lip. The first ring includes at least one first rolling ring having the first raceway and a first sealing ring secured to the first rolling ring. The second ring further includes at least one second rolling ring having the second raceway and a second sealing ring secured to the second rolling ring. The bearing also further includes a sealing module reversibly secured to the first and second sealing rings.

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 measuring device with a crankshaft and a load cell for determining a radial force acting on the crankshaft having a receiving sleeve for receiving a bearing ring and a fastening ring for attaching the load cell in a transmission housing. Axial support areas are provided on the fastening ring for axially supporting the outer ring of the first bearing. Moreover, measuring regions for receiving radial forces of the receiving sleeve are provided which connect the receiving sleeve with the fastening ring. Strain sensors are attached to at least two of the measuring regions. An evaluation electronics is connected to the strain sensors.

A slew bearing that includes an inner ring. The slew bearing also includes a first outer ring positioned about a first portion of the inner ring. The slew bearing also includes a second outer ring operably engaged with the first outer ring, wherein the second outer ring is positioned about a second portion of the inner ring opposite to the first outer ring. The slew bearing also includes at least one set of ball operably engaged with the inner ring and one or both of the first outer ring and the second outer ring. The inner ring of the slew bearing is configured to rotate about the first outer ring and the second outer ring.
