An identification device that is attached to a target component and stores identification information of the target component; and a first communication device and a second communication device that wirelessly communicate with the identification device. The second communication device holds and transmits the identification information acquired by the second communication device as second-communication-device acquisition information. The first communication device includes: a first-communication-device holder that holds the identification information acquired by the first communication device and the received second-communication-device acquisition information as first-communication-device acquisition information and a first-communication-device judging unit that judges whether or not the identification information having the same contents is contained in the first-communication-device acquisition information. When the first-communication-device judging unit judges that the identification information having the same contents is contained in the first-communication-device acquisition information the first-communication-device holder merges the identification information judged to have the same contents.

A spherical bearing comprising: a race; a ball; a wear lining; and a capacitive sensor positioned within or behind the wear lining to gauge wear of said wear lining.

The present invention relates to a connecting element for electrical and mechanical connection of electronics modules. The connecting element includes a base part having a receptacle area that serves to hold an electronics module, wherein the receptacle area has first electrical contact points for the electrical connection of the connecting element to electrical contact points of the electronics module. The base part includes a first end region having a first recessed section on the top side and has a second end region having a second recessed section on the bottom side. Second electrical contact points for connecting to further connecting elements are disposed on the top side of the first recessed section and on the bottom side of the second recessed section. The recessed sections are designed such that the end regions of connecting elements that are located next to each other can be positioned opposite one another in such a way that the top sides of the connecting elements are located on a plane and the bottom sides of the connecting elements are located on another plane. The second electrical contact points are disposed in such a way that the connecting elements can be positioned at different angles (a) with respect to one another. The invention also relates to an electronic module arrangement having at least one connecting element and an electronics module disposed in the receptacle area of the connecting element.

An axle box-bearing unit for an axle including a housing element and a sensor unit having a sensor module, a connection piece for connecting to a processing unit and a flexible electrical cable joining the sensor module and the connection piece into a single part. The housing element is delimited by an annular lateral wall provided with a transversal through hole engaged by a plug fitted in a fluid-tight manner to the flexible electrical cable between the sensor module and the connection piece. A first plate provided with a second through hole is rigidly connected to the lateral wall of the housing element, with the second hole aligned with the first hole and crossed through by the plug, a second U-shaped plate is fitted astride of the plug to connect with one end of same that projects radially from the holes and is rigidly connected to the first plate.

A system and method for detecting wear and/or failure of a ball joint. The system having a ball housing which retains a ball head of the ball joint therein. A ball race is received within the ball housing and receives the ball head of the ball joint. An inwardly facing surface of the ball race engages the bail head such that the ball head can pivot in relation to the ball housing. A detection component is supported by the ball race and is spaced from an exterior surface of the ball head by a set distance. The detection component issues an indicator signal to alert a driver when the detection component detects at least one of a worn or a failure condition of the ball joint.

Conveyor idler monitoring apparatus, systems and methods are provided. In some embodiments, one or more sensors (e.g., temperature sensors, load sensors, etc.) are supported by the shaft of a conveyor idler. In some embodiments, one or more sensors are in data communication with a wireless transmitter. In some embodiments, a power generator driven by rotation of the idler is in electrical communication with one or more sensors and/or a wireless transmitter. In some embodiments, a plurality of idlers monitoring systems are in data communication with a conveyor monitoring system and/or operational monitoring system.

A bearing arrangement comprising: a first bearing including a first inner race coupled to a rotatable component, a first outer race; and a plurality of first roller elements between the first inner race and the first outer race; a second bearing including a second inner race coupled to the rotatable component, a second outer race, and a plurality of second roller elements between the second inner race and the second outer race; a component, the first outer race being axially moveable relative to the component; and a member between the first bearing and the second bearing and arranged to provide an indirect first force on the first outer race to prevent the first roller elements from skidding when the first bearing and the second bearing receive a second force in a first direction, the second bearing being configured to transfer the second force to the component.

An apparatus for use in connecting a cover member to a retaining member coupled to a nut mounted to a shaft includes a body portion, arms, and a plurality of pressing members. The arms extend from the body portion relative to the nut such that contacting portions of the arms contact a rear side of the nut to connect the body portion to the nut. The plurality of pressing members extend from the body portion and is alignable with the plurality of tabs of a cover member when the cover member is located between the body and the nut. The body portion includes a press mechanism configured to cause a first pressing member of the pressing members to contact a first tab of the cover member to deform the first tab toward a retaining member coupled to the nut mounted on the shaft.

A rolling bearing cage includes at least one cage side ring and a plurality of cage bars extending from the cage side ring so as to form a plurality of pockets, each pocket being defined between a separate pair of adjacent bars, for receiving rolling bodies of the rolling bearing. A cage breakage detection unit includes at least one conductive track and a module for wireless cage breakage monitoring. The cage has at least one recess, in which at least a prefabricated part of the cage breakage detection unit is inserted and fixed.

A sliding bearing element with a first layer having a radially inner surface includes a measuring device arranged on the radially inner surface of the first layer. The measuring device includes, in the order indicated, a first electrical insulating layer, a sensor layer and a second electrical insulating layer. A sliding layer is arranged on the second electrical insulating layer.
