A computed tomography (CT) gantry system is described herein. The CT gantry system includes a frame, a plurality of support wheels rotatably coupled to the frame, and a gantry resting upon the plurality of support wheels. In some embodiments, the gantry includes two gantry rings, and a cross member extending between the two gantry rings. In other embodiments, the gantry includes a first gantry ring, and a second gantry ring spaced apart from the first gantry ring in a direction parallel to an axis of rotation of the gantry. In some embodiments, the plurality of support wheels includes a plurality of front support wheels and a plurality of back support wheels. In some embodiments, the gantry includes a front gantry ring resting upon the front support wheels, a back gantry ring resting upon the back support wheels, and a cross member coupled between the front and back gantry rings.

A roller of a support arrangement for a rotary milking platform, where the support arrangement includes a first rail member fixedly connected to the rotary platform, a second rail member stationarily arranged in a position below the platform, and a plurality of rollers arranged in a vertical space between the first rail member and the second rail member. Each roller includes a peripheral surface comprising a contact surface to be in contact with a contact portion of the first rail member and a contact portion of the second rail member. The peripheral surface of the roller includes two beveled surfaces arranged at opposite sides of the contact surface which are located at a smaller distance from a rotary axis of the roller than the contact surface.

A ball bearing assembly includes at least two units being axially coupled together to allow at least one set of plural spherical balls adapted to be installed between at least one pair of two adjacent units of the at least two units.

A magnetic conveyance system comprising a support structure having a ferromagnetic capacity and a trolley moveable upon the support structure in a plurality of directions. The trolley may include a trolley frame and at least one attractor cell disposed on the trolley frame. The at least one attractor cell may comprise a housing and at least one magnet, at least one friction reducing load spreading device, and a load transfer member disposed within the housing. The magnet may provide a magnetic attraction force between the trolley and the support structure. The friction reducing load spreading device may comprise a plurality of bearing balls circulating within a reservoir and a channel formed by the load transfer member disposed within the housing. The load transfer member may also include a bearing surface wherein a portion of the plurality of bearing balls is disposed between the bearing surface and the support structure.

A bearing system including a wheel assembly transmitting load to a damping assembly, wherein the wheel assembly is configured to rotate angularly relative to the damping assembly.

The at least one attractor cell may comprise a housing and at least one magnet, at least one friction reducing load spreading device, and a load transfer member disposed within the housing. The magnet may provide a magnetic attraction force between the trolley and the support structure. The friction reducing load spreading device may comprise a plurality of bearing balls circulating within a reservoir and a channel formed by the load transfer member disposed within the housing. The load transfer member may also include a bearing surface wherein a portion of the plurality of bearing balls is disposed between the bearing surface and the support structure.

An apparatus for rotatably supporting a rotating cylindrical body. The apparatus comprises a pair of roller assemblies for supporting an annular bearing surface of a rotating cylindrical body. Each of the roller assemblies comprises a cylindrical roller having a circumferential bearing surface in supporting engagement with the annular bearing surface of the rotating body; first and second shaft extensions extending from the roller; bearings for rotatably supporting the first and second shaft extensions; and a pivot plate for supporting the bearings, the pivot plate being pivotally attached to a base by a pivot pin such that the cylindrical roller self-adjusts to the annular bearing surface of the rotating body.

A ball bearing assembly includes at least two units being axially coupled together between which at least one set of plural spherical balls is installed to allow a shaft adapted to be run through and supported by the at least one set of plural balls.

A bearing system for a rotating turret mounted on a vessel includes upper radial and axial bearings placed on a stiff bearing support ring. The bearing support ring is isolated from deflections in the vessel's caisson. Through the isolation, the radial and axial bearings are less affected by deflection of the vessel for example due to waves. The bearing support ring is supported vertically by a system of hydraulic cylinders serviced by multiple hydraulic systems for redundancy. The bearing support ring alternatively can be supported by an articulated steel structure.

A marine turbine comprising a stator, a rotor, the rotor being able to be driven in rotation around an axis or rotation by a stream of a liquid, and at least one first bearing for supporting the rotor, the or each first bearing, comprising a magnetic stator element secured to the stator and magnetic rotor element secured to the rotor. The marine turbine further comprises at least one second bearing for supporting the rotor, the or each second bearing comprising at least one rolling element.
