A guide bearing system including a pad adjuster to traverse at least one bearing in a direction to adjust a radial clearance. The system can further include a sensor for measuring deviations in the radial clearance. In some embodiments, the guide bearing system includes a controller that receives a distance signal from the sensor measuring the radial clearance and signals the pad adjuster to traverse the at least one bearing to compensate for the deviations in the radial clearance.

In accordance with an embodiment, a bearing device comprises a sliding bearing including a main body and a plurality of first protrusions, the plurality of first protrusions protruding inward in a radial direction from the main body and being separated from each other in a circumferential direction; a housing including a holding portion; and a plurality of second protrusions, separated from each other in a circumferential direction, configured to protrude in the radial direction from at least one of an outer circumferential portion of the main body and an inner circumferential portion of the holding portion, and to form a gap extending in the circumferential direction between the main body and the holding portion.

Linear guides for shafts are disclosed The linear guides comprise housings having a main opening to receive the shaft and multiple contact guiding elements, such m bearings or sliders, arranged on the housing and around the opening, each contact guiding element to contact the shaft at a different point The linear guides further comprise thermal compensation blocks affixed to the housing and in contact with a portion of a contact guiding element of the multiple contact guiding elements.

A gear pump bearing block has a bush formed of antifriction alloys. The bush has a cylindrical portion providing a bore adapted to receive a bearing shaft of a gear of the pump. It further has a thrust face at the end of the cylindrical portion, the thrust face being adapted to slidingly engage with a side surface of the gear. The bush has an inner component providing the bore, and an outer component forming a radially outer surface of the cylindrical portion. The inner and outer components are formed of respective lead bronze alloys, the lead bronze alloy of the outer component having a higher lead content than the lead bronze alloy of the inner component.

The seal arrangement for a mid turbine frame of a gas turbine, especially an aircraft gas turbine, includes a tubular fluid duct, especially an oil duct, which extends along an axial direction, a bearing sleeve surrounding the fluid duct radially outside and in the peripheral direction, and at least one seal ring arranged between fluid duct and bearing sleeve in the radial direction, this ring being arranged around the fluid duct. The seal ring is taken up at least partly in a groove provided in the bearing sleeve.

The proposed solution relates to a stator vane assembly for an engine, having at least one stator vane of a stator vane row and a casing for the at least one stator vane row, wherein the at least one stator vane is mounted adjustably on the casing by means of a bearing journal, which is rotatably mounted in a bearing opening in the casing and passes through this bearing opening along a longitudinal axis.

A section of a sealing element, on which at least one sealing ridge extending radially in relation to the longitudinal axis is formed and/or which has a nonlinear slot passing longitudinally through the section, is provided within the bearing opening.

The present invention relates to a centrifugal pump and a bearing retainer for the centrifugal pump. The centrifugal pump has a shaft, a bearing for supporting the shaft, and a bearing retainer for the bearing. The bearing retainer comprises a ring section adapted to surround the bearing and an elastic section adjacent the ring section, wherein the elastic section comprises multiple slits, dividing the elastic section into multiple resilient parts, wherein the multiple resilient parts are adapted to receiving and supporting the bearing, thereby creating a compression force in radial direction perpendicular to the axis of the shaft, allowing the bearing retainer to hold the bearing in a fixed position with respect to the bearing retainer.

A resolver integrated-type bearing device includes a bearing configured to rotatably support a rotating shaft with respect to a housing, a rotor attached to the rotating shaft, and a stator disposed radially outward of the rotor with a gap therebetween. A stator core of the stator is integrally attached to the bearing.

A bearing, for supporting a rotation shaft of a rotatable member, capable of being supported by a supporting portion provided with an engaging hole engageable with the bearing includes positioning projections having contact surfaces and bearing projections having sliding surfaces on which an outer peripheral surface of the rotation shaft slides. The positioning projections project from different positions so that between adjacent positioning projections, an outer peripheral surface of the bearing and the inner wall surface of the engaging hole form a gap therebetween. The bearing projections project from different positions so that between adjacent bearing projections, an inner peripheral surface of the bearing and an outer peripheral surface of the rotation shaft form a gap therebetween. With respect to a circumferential direction of the rotation shaft, the positioning projections and the bearing projections are provided at positions different from each other.
