The tie-downs are attached to shelves attached to the vehicle adjacent and extending away from the support surface. The shelves comprise left-hand shelves and right-hand shelves. Alternatively, anchors are attached to the tie-downs for removably mounting the tie-downs within stake pockets of the vehicle.

A mobile body positioning station and a mobile body positioning system include a first partition, a second partition disposed along a direction intersecting an extending direction of the first partition, and a guide device as a guide disposed on a movement path of a robot as a mobile body. The guide device is disposed along an oblique direction with respect to the direction perpendicular to the extending direction of the first partition to extend from the first partition toward the second partition side. The guide device is configured to make the robot move in the oblique direction more easily than move in directions other than the oblique direction, and the guide device moves the robot along the first partition toward the second partition.

One of the first and second bearing portions can be at least partially composed of a high-temperature superconductor (HTS) and another can be at least partially composed of a magnet. The first bearing portion can be disposed at least partially within an opening of the second bearing portion with a gap between the first and second portions. A magnetic bearing portion can include a plurality of rings disposed next to one another. An HTS bearing portion can include a magnet. The bearing portions can be biased toward an alignment with one another. One bearing portion can rotate relative to another bearing portion.

A tribologically modified polyoxymethylene polymer composition is disclosed. In accordance with the present disclosure, the polyoxymethylene polymer composition contains a tribological modifier, such as polytetrafluoroethylene, in combination with a stabilizer package. The stabilizer package can include a guanamine compound in combination with at least one carboxylic acid salt. The stabilizer package minimizes formaldehyde emission.

A rolling bearing, in particular a center-free large rolling bearing, having two concentric ball races with one ball race comprising a groove open toward the other ball race, and the other ball race comprising a scraper ring engaging into the groove, wherein the scraper ring is supported at the groove in the axial direction of the rolling bearing by at least two axial bearings arranged at oppositely disposed scraper ring front side and wherein the scraper ring is supported in the radial direction by at least one radial bearing which is arranged on the scraper ring jacket surface. The scraper ring is supported in the axial direction at the groove by a third axial bearing, wherein two axial bearings are arranged at the same side of the scraper ring at separate raceways offset from tone another in the axial direction of the rolling bearing.

An arrangement for connecting a turret within a vessel opening such that the vessel is capable of rotation about a longitudinal axis of the turret. The arrangement including an inner ring assembly coupled to the turret and an outer ring assembly coupled to the vessel in concentric alignment with the inner ring assembly. A support row assembly connected between the inner and outer ring assemblies allows rotation of the outer ring assembly with respect to the inner ring assembly and axially transfers the weight of the turret to the vessel. A radial row assembly is coaxially disposed about the longitudinal axis between the inner and outer ring assemblies. A centralizer is disposed between the inner and outer ring assemblies. During normal operation the radial row assembly transfers any radial load from the vessel to the turret and the centralizer has a radial clearance with the outer ring assembly.

The present application relates to a balance bearing device, a control method thereof and a transport equipment. The balance bearing device is used for the transport equipment and includes two or more mobile assemblies, the two or more mobile assemblies being arranged to be stacked, each mobile assembly including a base, a mobile component and an adjusting component. The base has an arc-shaped guide rail, and the mobile component is arranged on the base and is able to move along the extension trajectory of the guide rail under the action of gravity. The adjusting component is connected between the mobile component and the base and is able to limit the limiting position of the mobile component moving along the guide rail; wherein the extension directions of the guide rails of two adjacent mobile assemblies intersect with each other, and the base of one of the two adjacent mobile assemblies is connected to the mobile component of the other. In the stacking direction of two or more mobile assemblies, the mobile assembly at the topmost layer is able to be connected to the component to be transported through the mobile component. The present application can meet the balance requirements of the component to be transported and ensure transport safety.

The invention relates to a pivot bearing assembly, comprising a pivot pin and at least one bearing block, in which a bearing bush having a bearing bore is accommodated, the pivot pin being slidingly supported in the bearing bore). In order to create an improved pivot bearing assembly, the bearing bush according to the invention has a rounded outer surface, which is inserted into a negatively rounded inner surface in order to orient the bearing bush.

In rotating machine having a vertically oriented rotating shaft, a static magnetic force is used to simulate rotor weight and create the desired bearing preload. By installing a magnet the gravity based preload on the shaft journal bearings of a horizontal machine can be simulated for a vertical shaft. This can increase rotor stability, reduce the machine's vulnerability to hydraulically induced imbalance forces and give a more smooth transition through various shaft speeds.

A wear pad assembly for a telescopic boom includes a wear pad having a first side for contacting an outer wall of an inner section of the boom, and a second side facing an inner wall of an outer section of the boom. At least one rigid plate is secured to the second side of the wear pad, and a stud in screw-threaded engagement with the outer section of the boom or a plate secured to the outer section of the boom is associated with each rigid plate, the end of stud and the associated rigid plate having mating formations to enable the stud to urge the first surface of the wear pad against the outer wall of the inner section while preventing the wear pad from being displaced in a plane normal to the axis of rotation of the stud.
