A boss configured for attachment to a pressure vessel includes a first bore therein and a bearing disposed at least partially within the first bore. A system for supporting a pressure vessel on a vessel mount includes a boss, a bearing, and an attachment element. The boss is attached to the pressure vessel and has a first bore therein. The bearing is disposed at least partially within the first bore and has a second bore therethrough. The attachment element is configured to be affixed to the vessel mount, wherein a portion of the attachment element extends through the second bore and is slidable within the first and second bores substantially along a longitudinal axis of the pressure vessel. A method is described for supporting a pressure vessel on a vessel mount.

The invention relates to an umbilical termination assembly for terminating a cable or umbilical. The termination assembly comprises a plurality of umbilical elements extending from an umbilical and which pass through a bulkhead plate. The seated ball element has a spherical body through which an umbilical element passes. The ball element is seated in a cup member which allows the ball element to rotate through a large range of angles allowing it to be aligned with the umbilical element without the umbilical element needing to be manipulated or forced into position. The umbilical element can then be attached to the ball element which is supported by the cup member on the bulkhead. This allows the axial tension in the umbilical element to be transferred to the bulkhead.

Systems and methods related to hydrodynamic bearings for use in X-ray sources are provided. In one aspect, a hydrodynamic bearing system includes a sleeve assembly including a cross-member fluidically dividing a first interior cavity from a second interior cavity, a first shaft positioned in the first interior cavity, and a second shaft positioned in the second interior cavity. The hydrodynamic bearing system may further include a first journal bearing including a first fluid interface surrounding at least a portion of the first cantilever shaft and configured to support radial loads and a second journal bearing including a second fluid interface surrounding at least a portion of the second cantilever shaft and configured to support radial loads.

A high pressure nozzle, including a longitudinal housing having a liquid inlet end and a liquid outlet end opposite to the liquid inlet end and comprising an internal channel running from the liquid inlet end to the liquid outlet end, a nozzle head support shaft, rotatably arranged partially in the internal channel and comprising a liquid channel in fluid communication with the internal channel, and a rotary nozzle head supported on the nozzle head support shaft and arranged outside the housing, wherein the rotary nozzle head is arranged to rotate about a longitudinal axis of rotation to provide a rotating spraying of liquid jetted from the rotary nozzle head. The high pressure nozzle includes an axial pressure compensator arranged in the internal channel, wherein the axial pressure compensator is arranged to substantially compensate axial pressure force from liquid entering the channel at the liquid inlet end.

An assembly comprising: a core in the form of a toroid; and at least one washer overlying the core, the washer comprising a polymer, wherein the washer has an arcuate cross-section so as to have a shape complementary to the core.

The present invention achieves a high mechanical load capacity of a rod end by means of a component loop that passes around a bearing, where the component may be made of continuous-fiber reinforced composite material with thermoplastic matrix and where the continuous-fiber reinforced composite material with thermoplastic matrix may extend into a threaded stem of the rod end, and the component made of continuous-fiber reinforced composite material with thermoplastic matrix may be enclosed by short-fiber reinforced, long-fiber reinforced, or unreinforced thermoplastic. The threaded stem can be implemented with an external or an internal thread.

Provided is a bearing structure that can support a rotary shaft with a small number of components. The bearing structure includes: a cylindrical sleeve (32) provided so as to surround the outer circumference of a rotary shaft (4) that rotates about a center axis line (CL) and configured to rotate together with the rotary shaft (4); thrust collars (34a, 34b) provided so as to abut against both ends in the center axis line (CL) direction of the cylindrical sleeve (32), respectively, having a larger diameter than the cylindrical sleeve (32), and configured to rotate together with the rotary shaft (4); and a compressor-side journal bearing (12) arranged on the outer circumference side of the cylindrical sleeve (32) and between the thrust collars (34a, 34b).
