The sealing head extends upward above the sealing base and extends outward beyond an upper portion of the sealing base to be located radially outward from the sealing base. The seal is located at an upper portion of the sealing base. The seal is located radially outward from the sealing base. The seal is located below the sealing head at a sealing aperture located between a sealing shoulder and a sealing neck.

A gantry assembly includes a rotor rotatable about a central axis, a stator fixed with respect to the axis and a bearing inner ring connected with the rotor and having an outer circumferential surface providing a least one inner raceway and two opposing axial end. A bearing outer ring is disposed about the inner ring and has an inner circumferential surface providing at least one outer raceway, first and second axial ends, an annular recess extending axially inwardly from the first axial end, and a plurality of threaded mounting holes extending axially-inwardly from the recess and spaced circumferentially about the central axis. An annular damper is disposed within the recess and a plurality of threaded fasteners each extend from the stator, through the damper and into a separate one of the plurality of threaded mounting holes to connect the bearing outer ring with the stator.

Provided is a fractal structure for power-generation of bearing rotating vibration that is installed on an outer ring of a bearing to generate power using vibration generated from a micro whirling motion of the bearing, the fractal structure including a housing which is in contact with the outer ring of the bearing to receive the vibration generated from the micro whirling motion of the bearing, and has a receiving space therein, a flexible element which is disposed in the receiving space while being in contact with an inner circumference of the housing to convert the vibration into a radial direction, and a piezoelectric element which is installed between the housing and the flexible element and disposed near the receiving space, and deforms upon receiving the vibration converted in the radial direction from the flexible element, thereby producing electricity.

A non-locating bearing assembly includes a bearing unit configured to support a rotating component relative to a stationary component, and the bearing unit includes a first stationary bearing ring and a second rotatable bearing ring that is fixedly connectable to the rotating component. The bearing assembly also includes a bearing carrier to which the stationary bearing ring is attached in a rotationally fixed but axially displaceable manner, and the bearing carrier is configured to be fixedly connected to the stationary component.

A gantry assembly includes a rotor, a stator and a bearing for coupling the rotor and the stator. The bearing includes an inner ring connected with the rotor or stator, an outer ring connected with the other one of the rotor and the stator and rolling elements between the two rings. The ring connected with the stator, preferably the outer ring, includes one or more damping washers disposed between the ring and the stator, each washer being disposed about one threaded fastener connecting the ring with the stator. Also, one or more damping cylinders are each disposed within a mounting hole of the ring connected with the stator and about a threaded fastener disposed within the hole. The bearing ring connected with the rotor may also include damping washers between the ring and the rotor or/and damping cylinders disposed within mounting holes receiving fasteners connecting the ring with the rotor.

A damper bearing includes: a bearing portion that supports a rotary shaft; and a tubular portion that is located around an outer circumference of the bearing portion, and has an outer surface attachable to a structural member. The bearing portion can be a hydrostatic bearing that supports the rotary shaft with a predetermined bearing clearance therebetween. The tubular portion includes a plurality of planar slits arranged circumferentially at predetermined intervals in the tubular portion. Each slit extends radially from an open end at the outer surface, and extends circumferentially in an arc to a predetermined point in a region between the outer and inner surfaces. The tubular portion includes a bearing fluid supply hole that is formed in a region where none of the planar slits is situated, and extends from the outer surface of the tubular portion to the bearing portion without passing through any of the planar slits.

A device for damping a rolling bearing includes a support and a radially flexible cage. The cage includes a ring provided in order to be mounted on the periphery of a rolling bearing. The radial flexibility of this cage results from the structure thereof which is perforated by oblique posts connecting the ring to an attachment annulus of this cage. The support includes a plurality of teeth each extending radially through a respective inter-post opening of the cage. The ring and the support form, radially between one another, a fluid damping cavity suitable for forming a compressed fluid film. The device allows a controlled radial movement of the ring, the latter being radially limited by the support, while having a limited footprint.

A suspension thrust bearing device for use with a suspension spring in an automotive suspension strut of a vehicle. The device includes an upper annular bearing member and a lower annular bearing member in relative rotation. The lower annular bearing member having a body provided with an embedded stiffening insert. The device further provides a damping element made of resilient material and interposed between the lower annular bearing member and the suspension spring. A radial flange of the damping element prevents separation from the lower side of the radial flange of the lower cap.
