The invention relates to a bearing for supporting a shaft, in particular a rudder shaft, or a rudder blade, by means of which bearing the bearing clearance or the bearing wear can be continuously monitored, determined, and optionally documented. According to the invention, for a bearing for supporting a shaft, in particular a rudder shaft, comprising a first bearing element and a second bearing element, wherein the first bearing element has a sliding surface for contacting the second bearing element in a sliding manner, and a measurement-value sensor having a wear surface for contacting the second bearing element in a sliding manner, the at least one measurement-value sensor is not pin-shaped.

A large rolling bearing assembly includes a rolling bearing and at least one displacement sensor module. The rolling bearing includes an inner ring, an outer ring, and a plurality of rolling elements between the inner ring and the outer ring, the inner ring is supported on a shaft, the outer ring is mounted in a housing, and the at least one displacement sensor module is configured to measure a radial position of the shaft in order to detect wear of the rolling bearing.

An adjustable spacer with a non-hardened intermediate portion therebetween is mountable between a pair of roller bearings also mounted on a shaft such an axle or spindle or the like. The intermediate portion allows the spacer to collapse in the axial direction to maintain desired axial loads on the bearings.

The present disclosure relates to a device for detecting and identifying play and checking the attachment of wheel, steering-assembly and suspension parts of vehicles. The device includes a linearly displaceable carriage and a supporting plate which is configured to support a wheel of a vehicle. The supporting plate is rotatable, and the carriage is displaceable with respect to the supporting plate in a direction corresponding to the transverse direction of the vehicle. Additionally, the carriage includes a rotatable structure which is configured to rotate the supporting plate about an axis of rotation.
