A method for manufacturing a sliding layer of a slide bearing includes applying any of the following alloys and/or materials, namely SnSb8Cu4, SnSb12Cu6Zn, CuSn12Ni2, CuAl10Fe1, tin and aluminum bronzes, aluminum materials and alloys made therefrom, to a base body in a laser-based application process, wherein the alloy and/or material for application is in the form of a powder or compacted powder or as a wire.

A compressor includes a housing, a shaft that is rotated relative to the housing to compress a working fluid, and a foil bearing that supports the shaft. The foil bearing includes a top foil. The foil bearing is a foil gas bearing that is backed up by a ball bearing, or a mesh foil bearing with an actuator to compress a wire mesh dampener. A heat transfer circuit includes a compressor and a working fluid. The compressor includes a shaft that is rotated to compress the working fluid, and a foil bearing for supporting the shaft as it rotates.

Solar trackers that may be advantageously employed on sloped and/or variable terrain to rotate solar panels to track motion of the sun across the sky include bearing assemblies and other mechanical features configured to address mechanical challenges posed by the sloped and/or variable terrain that might otherwise prevent or complicate use of solar trackers on such terrain.

A propulsion unit includes a housing supported on a vessel. A propeller shaft extends in the housing. The propeller shaft is rotatably supported with a first bearing and a second bearing. A propeller is attached to at least one end of the propeller shaft. The first bearing includes a first radial bearing and a first thrust bearing. The first radial bearing is a sliding bearing positioned axially inside the first thrust bearing. The first bearing is positioned at the first end of the housing and the second bearing being positioned at the second end of the housing or vice a versa.

A thrust gas bearing includes a collar portion fixed to a shaft portion, a first base part facing one axial end surface of the collar portion, a first gas film forming part formed between the collar portion and first base part, a second base part facing an other axial end surface of the collar portion, a second gas film forming part formed between the collar portion and second base part, and a cooling flow path to carry a fluid flow. The cooling flow path includes a first flow path formed on one axial end side of the first base part and extending from an axial center toward an outer periphery, and a second flow path formed on an other axial end side of the second base part and extending from an outer periphery toward an axial center. The second to flow path is located downstream of the first flow path.

The present invention relates to a high pressure nozzle (1), comprising a longitudinal housing (11, 12), with an internal channel (15) therein, a nozzle head support shaft (20), which is rotatably arranged partially in the internal channel (15), a rotary nozzle head (30), which is attached to the nozzle head support shaft (20) and arranged outside the housing (11, 12), and an axial bearing seat (40), which is located within the housing (11, 12) and which comprises an axial bearing surface (41) that faces an end surface (22) of he nozzle head support shaft (20). The axial bearing surface (41) and the support shaft end surface (22), during use, cooperate to form an axial bearing for the nozzle head support shaft (20) and the axial bearing seat (40) comprises an axial bore (42) in the axial bearing surface that is aligned concentrically with an axis of rotation of the nozzle.

A thrust bearing is described comprising first and second bearing assemblies (15, 17) rotatable relative to each and a plurality of axially arranged bearing stages (14a, 14b) formed between the first and second bearing assemblies (15, 17). Each bearing stage comprises a first load shoulder (16) provided on the first bearing assembly (15), a second load shoulder (18) provided on the second bearing assembly (17), a bearing structure (30) defined between the first and second load shoulders; and an extrudable component (32) forming part of the bearing structure. Wherein axial load applied between the first and second bearing assemblies (15, 17) in a first relative axial direction is transmitted between respective pairs of first and second load shoulders via the extrudable components (32) of respective bearing structures (30). The extrudable components (30) provide for load balancing between each bearing stage (14a, 14b).
