A bearing assembly is configured to retain a distal end of an impeller of a blood pump, where the impeller includes a drive shaft. The bearing assembly includes a pivot member coupled to a distal end of the drive shaft; a distal bearing cup having a proximally-facing surface configured to engage at least a portion of a distal section of the pivot member; and a sleeve bearing disposed around at least a portion of a proximal section of the pivot member.

A wind turbine rotary connection for two wind turbine components which are rotatable relative to each other, having a combined axial-radial bearing, wherein the axial-radial bearing has an axial bearing component and a separate radial bearing component. In particular it is proposed that the axial bearing component is in the form of a plain bearing component having a first convexly curved bearing surface and a corresponding second concavely curved bearing surface.

In a support structure for a rotating member, in which a support body supporting a rotating member so as to be rotatable around a predetermined axis is provided with a spherical support face that is recessed toward a side opposite to the rotating member, and a back face of the rotating member is rotatably and slidably supported on the support face, the back face of the rotating member is formed as a convexly curved face that is curved so that portions on opposite sides of the axis each protrude toward the support face when viewed in a cross section containing an entirety of the axis. In order for the back face to be supported on the support face via an apex portion of the convexly curved face, a radius of curvature of at least the apex portion is set smaller than a radius of curvature of the support face.

A centrifugal pump for delivering coolant in vehicles and providing a centering of a pump impeller and a dampening of motor vibrations. The centrifugal pump having a pump housing consisting of a pump head, which forms a single part with a suction nozzle, a discharge nozzle, a spoke, and a bearing support, in which a counter bearing is mounted, in which a first region of a shaft is supported, around which a pump impeller is rotatably mounted via a slide bearing secured in the pump impeller, the spoke retaining the bearing support in a central position within the pump head and having a containment shell, which separates a wet chamber from a dry chamber and in which a second region of the shaft is supported. The invention seeks to solve the problem of providing in a generic centrifugal pump.

A supercharging device, for example an exhaust gas turbocharger, may include a rotor mounted in a housing via an axial bearing. The axial bearing may include an axial bearing disc, a membrane, and a screw connection that secures the axial bearing disc to the membrane through an opening in the membrane. The axial bearing may further include a bush connected to the housing. The membrane may be clamped in between the bush and the housing. An adjusting screw may be inserted into an opening of the bush. The adjusting screw may delimit and/or facilitate an axial movement of the screw connection and the axial bearing disc.

A bearing assembly may be provided for mounting a rotor which can be rotated about a rotational axis. In particular, for a rotary fluid pump or rotary blood pump comprising: a main body, a bearing element which can be displaced relative to the main body in the direction of the rotational axis for receiving the rotor, and an adjusting device which is connected to the bearing element for displacing the bearing element in the direction of the rotational axis by a predefined distance, wherein the predefined distance is <=500 micrometres.

A fluid pump conveys a fluid, such as blood. A fluid channel that is bounded by a channel wall and a rotor arranged in the fluid channel and that is rotatably mounted about a pivot point of the bearing with a mechanical, hydrodynamic and/or hydrostatic, axial and radial bearing. The fluid channel has a spherical section and the rotor has a rotor body and a conveying element that is arranged within the spherical section of the fluid channel and configured to generate a substantially spherical rotational area of the rotor. The spherical center of the spherical section of the fluid channel and the spherical center of the spherical rotational area substantially coincide with the pivot point so that a minimum distance between the rotor and the channel wall is maintained in the spherical section upon a tilting of the rotor.
