A bearing unit having a stationary radially outer ring, a radially inner ring rotatable around a central rotation axis (Y) of the bearing unit, at least one row of rolling elements interposed between the radially outer ring and the radially inner ring, an eccentric collar for clamping the radially inner ring on a rotating shaft (S), and a first pressure screw on the eccentric collar, wherein the eccentric collar is provided with a second pressure screw which increases the gripping capacity of the bearing unit on the rotating shaft (S).

A spindle-shaft unit for closing containers with a screw closure includes a spindle that is rotatable and axially movable relative to a housing and a bearing unit arranged between the housing and the spindle. The bearing unit comprises a sliding bearing that interacts with the spindle and a further bearing that interacts with the sliding bearing. The spindle is arranged at the sliding bearing such as to be displaceable and non-rotatable relative to the sliding bearing. The further bearing secures the sliding bearing so as to be rotatable and non-displaceable relative to the housing.

A flywheel system comprises a flywheel rotor comprising a rotor disc and a rotor shaft and has a longitudinal axis extending centrally through the rotor disc and the rotor shaft. The system further comprises a journal assembly configured to facilitate rotation of the flywheel rotor. The journal assembly comprises a sleeve having an aperture extending therethrough from a first end to a second, opposite end, a rod at least partially disposed within the aperture of the sleeve, and a nut coupled to a portion of the rod. The rod has a length greater than the sleeve such that a portion of the rod extends axially beyond the first end of the sleeve. A method of forming the flywheel comprises coupling the rod to the rotor shaft and pulling the second end of the rod to tension the rod. The nut maintains the tension in the rod when coupled thereto.

A compressor assembly is provided. Embodiments of the present disclosure generally relate to compressors used in chiller air conditioning systems for indoor spaces. The disclosed compressors have magnetic bearings that support rotating components. In one embodiment, the compressor comprises a partially segmented thrust bearing stator core. Additional systems, devices, and methods are also disclosed.

A UTV double row tapered wheel bearing assembly may include a first inner diameter race, a second inner diameter race axially offset from the first inner diameter race, and an outer diameter race radially offset from the first inner diameter race and the second inner diameter race, the outer diameter race formed as a single integral member. A first ring of rollers may be disposed between the outer diameter race and the first inner diameter race. A second ring of rollers may be disposed between the outer diameter race and the second inner diameter race. A first shield may be coupled to a first axial face of the bearing, and a second shield may be coupled to the second axial face of the bearing.

A drive shaft has a central tubular portion formed of a polymer composite with imbedded fibers. It extends between a first end and a second end. The central tubular portion has an outer peripheral surface. There is at least one ring on the outer peripheral surface of the central tubular portion. A method of repairing a composite material tube includes the steps of (a) identifying a damaged area on a composite tube, and (b) placing a patch on a surface of the tube and over the damaged area.

The present invention relates to a bearing cup set for a steering column comprising a bearing cup and a securing element, wherein the bearing cup has a bearing cup portion for the at least partial receiving of a rolling bearing and a holding portion extending radially outwards starting from the bearing cup portion. The bearing cup portion has a first opening side with a collar extending radially inwards and a second opening side. The securing element is connected to the bearing cup in such a manner that the securing element fixes a rolling bearing received by the bearing cup portion in the axial direction in respect of the bearing cup. A steering column comprises a jacket tube in which a steering shaft is received by the rolling bearing so as to be rotatable. The rolling bearing is arranged in the bearing cup portion of the bearing cup.

A pulley device for a transmission element having a pulley, a bearing, and at least one sleeve mounted freely in the bore of the inner ring of the bearing. The pulley device includes at least one annular protection shield, the shield retained axially in a first element from the pulley and coming into immediate proximity with the other element, the other element having at least one shoulder projecting radially ensuring that it is axially retained with the shield.

A thin section bearing assembly is for a gantry assembly and includes inner and outer rings each having inner and outer circumferential surfaces and rolling elements grooves and are each sized such that a ratio of the inside diameter to radial thickness is at least thirty (30). A plurality of rolling elements, preferably balls, are disposed between the outer ring groove and the inner ring groove. At least one elastomeric annular damper is disposed between the outer ring and the housing and/or between the inner ring and the rotor and has first and second axially spaced sections. As such, the first section is compressed more than the second section under bending moments in a first angular direction and the second section is compressed more than the first section under moments in a second angular direction. The one or more annular dampers each have a thickness calculated to optimize vibration reduction.
