A swiveling device includes a head part and a drive part, the drive part having an electric motor and the head part having a worm gearing, which can be driven by means of the electric motor, the worm gearing having a drive-side shaft with at least one screw thread and a helical gear wheel meshing therein, an output shaft being drivable by means of the gear wheel and the output shaft being connected for conjoint rotation to at least one swiveling element, and the drive-side shaft being mounted on both sides of its at least one screw thread in a housing of the head part by means of rolling bearings. The drive-side shaft is adjustable with respect to its axis of rotation in a plane arranged perpendicular to the axis of rotation of the gear wheel by an adjustment component of the drive-side shaft perpendicular to its axis of rotation.

In a three row, roller bearing assembly coupling a vessel to a turret, the bearing assembly having a support row assembly disposed between an inner ring connected to the turret and outer rings connected to the vessel, a method and arrangement for in situ remediation of a damaged support row assembly. Couplers are secured to existing inner ring stud bolts. A continuous bearing ring below the couplers is assembled and a support bearing arrangement is installed between the couplers and the bearing ring. Reaction plates are mounted to the vessel. Each reaction plate has a jack screw which is positioned directly below the bearing ring. The jack screws are turned to elevate the bearing ring and form a flat surface for support of the support bearing arrangement. The turret axial load is transferred from the damaged support row assembly to the support bearing arrangement.

A spinner collar engages any suitable device to enable the device to spin about the bearing axis of the spinner collar. A device such as a lighter with a long axis is engaged about the long axis by the spinner collar such that the bearing axis of the spinner collar is perpendicular to the long axis of the lighter enabling rotation of the long axis of the lighter about the bearing axis of the spinner collar.

A method for setting a preload in a bearing assembly, the bearing assembly having at least one rolling-element bearing with at least one bearing inner ring and at least one bearing outer ring, the method including changing the preload in the bearing assembly starting from an initial value and measuring the electrical resistance between the bearing inner ring and the bearing outer ring and terminating the changing of the preload in the bearing assembly in response to a target value for the electrical resistance being reached.

A device for adjusting a rolling bearing for mutual sliding of mast members for supporting a fork carriage of a fork lift truck includes a threaded coupling between an inner ring of the rolling bearing and a relative support pin, and an actuation member freely rotatable through the support pin and rotatably connected with the inner ring. The actuation member can be maneuvered to rotate the inner ring and vary the axial position of the rolling bearing with respect to the support pin through the threaded coupling.

A transmission has a housing, and a first and a second shaft, each of which has a bevel gearwheel. The two bevel gearwheels are in meshing engagement with one another. The first shaft with a first bevel gearwheel is designed as an axially adjustable shaft and, for this purpose, is supported by two rolling bearings on both sides of the bevel gearwheel, wherein each of the rolling bearings has a shaft-side inner ring and a housing-side outer ring. The shaft-side inner rings are provided in a defined axial position on the first shaft, while the housing-side outer rings of the rolling bearings are guided on respective housing-side support surfaces and are restricted from moving toward one another solely by the inner rings and the shaft. The axial position of the housing-side outer rings of the rolling bearings can be adjusted on the side facing away from the bevel gearwheel by respective adjusting devices. Each of the adjusting devices has an adjusting element with an external thread on the side of the respective outer ring facing away from the bevel gearwheel. The external thread is inserted into an internal thread in the housing. The internal thread and the external thread are designed as fine threads, preferably with a pitch of at most 0.75 mm.

A magnetically stabilized propshaft bearing system includes a bracket having a bearing receiving zone, an isolator arranged in the bearing receiving zone, and a propshaft bearing arranged in the bearing receiving zone and supported by the isolator. The propshaft bearing is receptive to rotatably support a propshaft for a vehicle. An electromagnet is mounted in the bracket surrounding a portion of the bearing. The electromagnet is selectively activated to shift the propshaft bearing within the bearing receiving zone.
