摘要： Wear detection in a plain bearing is proposed, with a first component comprising at least one sliding element of plastics material, which has a sliding surface for mobile guidance of a second component relative to the first component. The first component, in particular the sliding element, has a device for detecting wear in a critical region of the sliding element, in particular at the sliding surface thereof, with a transponder and with a detector element which cooperates with the transponder and is arranged on the sliding element. The detector element changes the behavior of the transponder when a predetermined degree of wear is reached in the critical region of the plastics sliding element, such that the wear-induced change is wirelessly detectable. The system and detection method are particularly advantageous for plain bearings for a lubricant-free bearing arrangement.

摘要： The sensor bearing unit provides a bearing having an inner ring and an outer ring centered on an axis, the inner ring mounted on a shaft, and an impulse ring provided with a target holder and with a target mounted on the target holder, the target holder being secured to the inner ring. The target holder includes anti-rotation features adapted to cooperate with complementary anti-rotation features of the shaft so as to prevent angular movement of the impulse ring relative to the shaft by abutment in circumferential direction.

摘要： A wheel bearing assembly for trucks includes a brake element and a wheel adapter defining a rotating component, an axle element defining a stationary component, and a multi-row, preferably double-row, bearing unit. The bearing unit has a first bearing ring, a second bearing ring and a plurality of rolling elements disposed between the first and the second bearing ring. The first bearing ring is connected to a drive shaft, the second bearing ring is connected to the axle element and the wheel adapter is configured to connect the first bearing ring to the wheel and the brake element. A shield is disposed between the brake element and the first bearing ring and/or disposed between the brake element and the axle element and is configured to shield a space defined by the first bearing ring, the wheel adapter and the brake element from entry of particles and/or water.

摘要： 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.
