A solid lubricant 11 is formed by molding and firing powder that includes amorphous and self-sintering carbon material powder 12, graphite powder 13, and a binder 14. The solid lubricant has high material strength and hardness, and also excellent impact resistance and wear resistance.

A lubrication system for an enclosed rolling element bearing may be achieved through a channel drilled through the outer race of the bearing and the outer surface of the bearing housing. The channel provides a direct path for the injection of lubricant via a grease gun or syringe to reach the rolling elements within. The lubrication system can be adjusted to assure lubricant does not leak from the channel with the addition of a tube or hollow screw or combination of the two along the entirety of the channel.

The disclosure relates to a device for improving a vacuum in the housing of a machine, in particular a centrifugal-mass energy store, comprising a rotor, for example a shaft having a centrifugal mass arranged thereon, which rotor is supported on at least one superconducting bearing in a contactless manner and is arranged in a vacuum container. In order to maintain the operating state of the superconducting bearing, the superconducting bearing is thermally connected to a cold source cooled by a cryogenic medium. According to the invention, the vacuum in the vacuum container is improved by means of an adsorber thermally connected to a cooling apparatus. The cooling of the adsorber occurs preferably by means of evaporated cooling medium from the superconducting bearing.

A rolling bearing of the present invention includes an inner ring, an outer ring and a rolling element which are all made of a steel material, and (A) a surface of the rolling element is formed with an Ag coating film, and a raceway of at least one of the inner ring and the outer ring is formed with a Cr coating film or (B) a surface of the rolling element is formed with a Cr coating film, and a raceway of at least one of the inner ring and the outer ring is formed with a Cr coating film.

A method and apparatus for coating and baking and deposition of surfaces on glass substrate or flexible substrate, such as films and thin glass sheets or other similar work pieces as it transitions thru and between small gaps of aero-static or hydro-static porous media bearings and differentially pumped vacuum grooves, in a non-contact manner, in order to process within a vacuum environment. The process is also intended to incorporate simultaneous and immediately sequential ordering of various processes.

A drive system as disclosed includes an input shaft, an output shaft, and at least two coupling elements respectively coupled to the input shaft and the output shaft. In order to absorb assembly and manufacturing tolerances with respect to the shafts, the coupling elements and their attachment to the shafts and thereby prevent jamming of the drive system, at least one coupling element has an elastically deformable section, the elastically deformable section having a different material or a different cross-section than an adjacent section of the coupling element.

A magnetic fluid seal includes an outer cylinder member with a heat barrier that internally houses a rotating shaft extending from a housing of a fluid machine and includes an attachment portion to be attached to the housing, magnetic pole members that are disposed around the rotating shaft housed in the outer cylinder member and form a magnetic circuit, and sealing films that are magnetically connected to the magnetic circuit, are respectively disposed between the magnetic pole members and the rotating shaft, are made of magnetic fluids, and are formed in an axial direction.

A testing apparatus includes a chamber, having an interior maintained at a predetermined pressure, a rotor rotatably disposed within the interior of the chamber, and a sensor disposed within the interior of the chamber. When the rotor rotates, the at least one sensor measures a testing characteristic of an object disposed within the interior of the chamber as the object interacts with the rotating rotor. A method includes setting a predetermined pressure of a chamber, rotating a rotor, and maintaining a gap between a surface of an object to be tested and a surface of the rotor by adjusting, with an actuator, the object to be tested or the rotor based upon a change, as measured by a laser, in the dimension of the object to be tested or the rotor.
