The invention relates to a tilting pad bearing for supporting a shaft having a longitudinal axis, the tilting pad bearing having—at least two tilting pads which are spaced apart from one another and each have a bearing surface and—at least one hot oil drainer which is arranged in an intermediate space between the at least two tilting pads, the at least one hot oil drainer being supported so as to be movable in the direction to and from the shaft.

Provided is a fluid film bearing, especially for a rotor hub in a wind turbine, including an inner part that supports a rotating outer part, wherein the inner part includes multiple radial pads distributed along the outer circumference of the inner part, each of the radial pads having at least one radial pad sliding surface, wherein the radial pad sliding surfaces support at least one outer part sliding surface of the outer part in the radial direction.

Provided is a fluid film bearing, for a rotor hub in a wind turbine, including a first and second part rotatably connected to each other, wherein the first part forms a first annular sliding surface that extends in the circumferential direction of the bearing along the first part, wherein the second part includes a support structure and first pads distributed along the circumference of the support structure, wherein a respective pad sliding surface of each of the first pads or of a first subgroup of the first pads supports the first annular sliding surface, wherein each first pad includes a mounting section that is mounted to a backside of the support structure, a contact section that is either forming the respective pad sliding surface or carrying a coating that forms the respective pad sliding surface and a connecting section that connects the contact section with the mounting section.

A hydrodynamic bearing in the form of a flex pad bearing includes configurations structured to change a bearing characteristic. One form of the bearing includes a nonlinear back wall that includes a circular arc and a transition, where the back wall extends radially outward of a ligament. The bearing can include an opening for the deposit of a weighted mass, wherein the opening can threadingly receive a threaded weighted mass. In one form a sidewall that includes the back wall segment can have an average outer radius which determines a thickness of the flex pads.

A journal bearing includes an oil supply nozzle, having an oil distribution part which extends in an axial direction of the rotation shaft and supplies lubricating oil, and a pad, provided at the rear side of the oil supply nozzle, in a rotational direction of the rotation shaft and supporting the rotation shaft rotatably. The inner periphery face of the pad, which opposes the outer periphery face of the rotation shaft, has an opening side face, in which the radial direction spacing between the inner periphery face and the outer periphery face of the rotation shaft becomes smaller, from the front end face of the pad, located at the front side in the rotational direction of the rotation shaft, toward the rear side in the rotational direction, and between the oil distribution part and the pad, the journal bearing has a bubble discharge path which discharges air bubbles.

A telescopic strut, in particular for a device for lifting loads, in particular for a hanger for vehicles or vehicle parts, wherein the telescopic strut consists of an outer tube and an inner tube guided therein, wherein the inner tube is movable longitudinal direction in the outer tube, where a number of sliding shoes are attached to the outer tube to guide the inner tube, where the sliding shoes have each been introduced from the outside into an opening in the wall of the outer tube and protrude inwardly to guide the inner tube such that the telescopic strut, which is structurally simple and therefore inexpensive to produce, has good sliding properties, has little guide play and is easy to maintain.
