A stack bearing assembly is provided having stacked bearing rings and bearing balls located between the rings in races. The bearing balls are formed from 100Cr6 steel that is carbonitrided. After carbonitriding, the bearing balls are polished. The carbonitrided and polished bearing balls are assembled in the races of the bearing rings to provide increased resistance to wear from the debris traveling through the bearing assembly in use, and increase toughness in order to withstand the wear caused by debris in a drilling rig. A method of producing a stack bearing assembly is also provided.

A non-magnetic ball housing can include an enclosed end and an open end. A plurality of non-magnetic ball bearings can be positioned within the enclosed end of the non-magnetic housing. A ball magnet can be adjacent to the plurality of non-magnetic ball bearings. A non-magnetic restraining plate can be coupled to the open end of the non-magnetic housing to secure the ball magnet within the non-magnetic ball housing while allowing the ball magnet to freely rotate within the non-magnetic ball housing. The non-magnetic restraining plate can include a restraining plate opening such that at least a portion of the ball magnet protrudes out of the restraining plate opening. A diameter of the restraining plate opening can be less than a diameter of the ball magnet. A metal channel can be magnetically coupled to at least a portion of the ball magnet protruding out of the restraining plate opening.

The present invention relates to a ball joint housing which pivotably supports a ball head of a ball stud received in an inner space thereof and in which a dust cover is installed to prevent foreign substances from entering into the inner space, includes: a receiving limit providing portion for providing a limit in receiving the ball head in the inner space; a contact portion integrally formed with the receiving limit providing portion, wherein the dust cover is brought into contact with the contact portion; and a deformation portion integrally formed with the contact portion; wherein a process in which the deformation portion is deformed inwardly proceeds when the ball head is received in the inner space, wherein the ball head received in the inner space is prevented from being separated by the process.

A thrust washer for a sliding bearing may include a thrust washer substrate having an axial face. The thrust washer may also have a polymer layer of profiled thickness on the axial face of the substrate. The profiled polymer layer may be provided with at least one oil distribution groove.

The present invention relates to a method for producing bearing shells of plain bearings, in which the bearing shells are blasted with corundum particles on the bearing metal side, in order in this way to produce residual compressive stresses in the blasted side of the bearing shell. Furthermore, the present invention relates to a bearing shell produced using such a method.

A planet gearbox is provided for connection to a carrier of an epicyclic gearing arrangement with a single input and single output and including a sun gear, a ring gear and at least one double helix planet gear rotatable on a cylindrical roller bearing with a cage having a cross-web thickness of 15% to 25% of the diameter of the cylindrical rollers and an L/D ratio exceeding 1.0. A gas turbine engine includes a fan and LP shaft, which couples a compressor to a turbine. An epicyclic gearing arrangement has a single input from the LP shaft coupled to a sun gear, a single output coupled to the fan's shaft, and a planet bearing cage having a cross-web thickness measuring 15% to 25% of the roller's diameter.

Embodiments of the present disclosure are directed to an adhesive layer, bearing including the adhesive layer, and methods of forming. The adhesive layer can include a mixture of a first polymer, a second polymer, and a third polymer, wherein the third polymer is a modified fluoropolymer of the second polymer. In a particular embodiment, a weight ratio of a weight content of the second polymer to a weight content of the third polymer in the mixture can be at least 12:1. In another particular embodiment, the adhesive layer can have a normalized peel strength of at least 4.8 N/in/microns.

An object is to provide a self-heat-generating fixing roller that has a simple structure and good durability and that can be easily produced. A self-heat-generating fixing roller according to an embodiment of the present invention includes a columnar core bar, a heat-insulating layer stacked on an outer circumferential side of the core bar, a heat-generating layer stacked on an outer circumferential side of the heat-insulating layer and heated by supplying electricity, and a mold-releasing layer stacked on an outer circumferential side of the heat-generating layer. The heat-insulating layer preferably contains a matrix containing a synthetic resin or rubber as a main component, and a plurality of pores contained in the matrix. The heat-generating layer preferably contains a matrix containing a synthetic resin or rubber as a main component, and a plurality of electrically conductive fillers contained in the matrix.

A linear motion assembly including a component having a longitudinal axis and adapted to translate along the longitudinal axis, and a bearing comprising a spiral body including a substrate and a low friction material, wherein the bearing extends around the component and provides a low friction interface for translation of the component, and wherein the bearing is adapted to prevent longitudinal translation of the component in a locked condition and permit longitudinal translation of the component in an unlocked condition. In an embodiment, the bearing is adapted to transition between the locked and unlocked conditions upon circumferential translation of an axial end of the spiral body, longitudinal translation of an axial end of the spiral body, or a combination thereof.
