A bearing including a substrate and a low friction layer, where the bearing includes an annular shape including a radial bearing portion in the form of an axially-extending base region, and an axial bearing portion in the form of a radially-extending flange, where the axial bearing portion terminates in a deep drawn axially extending lip, and at least one of a radial coining region or an axial coining region, where the radial coining region is positioned along the radially-extending flange and forms an annular depression, where the axial coining region is positioned along the axially-extending base region, and where the axial coining region is deformed so as to be non-parallel to a longitudinal axis of the bearing.

A method of determining an amount of wear in a spherical working surface of a bearing ring of a spherical plain bearing, the method including providing a reference groove of predetermined depth in an unworn working surface, using the reference groove and axial end faces of the bearing ring as reference surfaces for centering and aligning a measuring tool. The tool having a first surface, and a protrusion that extends from the first surface in radial direction and is adapted to fit into the reference groove and two or more radial openings that extend from a second surface of the tool. Determining the amount of wear by measuring the radial distance to the spherical working surface through each of the radial openings and comparing the measured value with a reference value measured using the tool for an unworn working surface comprising a reference groove of the same predetermined depth.

Generally, this disclosure provides systems including one or more hinges to allow a multiple-screen display device to transition (or fold) between a fully open (screens out) configuration, a tablet configuration, a fully closed configuration, and a plurality of in-between angled configurations. The systems provided in this disclosure may further allow the screens in the open configuration to be positioned advantageously close to each other, minimizing the gap between them. Additionally, the systems and apparatuses described herein may facilitate transitioning between various orientations/configurations with beneficially minimal user input.

A plain bearing comprising a generally cylindrical sidewall having a first axial end and a second axial end; and a curved portion disposed at the first axial end, wherein the generally cylindrical sidewall has a thickness, wherein the curved portion has an effective material thickness, wherein the effective material thickness of the curved portion is n-times thicker than the thickness of the generally cylindrical sidewall, and wherein n equals 2, 3, 4, or even 5.

A roller for a roller door has a roller bearing surrounded by a roller on the outer circumference and into which a bearing pin is inserted on the inner circumference, which protrudes in the axial direction from the roller bearing. The bearing pin has an inner part of a harder material and a bearing sleeve made of a softer material, wherein the inner part is pressed or screwed into the bearing sleeve. A method for mounting a roller includes injection molding a bearing sleeve made of plastic, inserting and/or screwing an inner part into an inner ring of a roller bearing and the bearing sleeve, and fixing the inner part to the bearing sleeve in a force-locked manner, and applying a roller to an outer ring of the roller bearing.

An adjustment system comprising: a pivot nut comprising a pivot nut aperture feature configured to accept the lower portion of a pivot bolt; a floor mount having a slot in which the pivot nut is slidingly engaged so as to have a movement including forward-backward, side-to-side and rotational, the floor mount having a floor mount aperture that aligns with the pivot nut aperture; and a cover configured to mount over the floor mount and engage with the pivot nut so as to move with the pivot nut.

A hinge assembly comprises first and second tape spring elements, wherein each of the spring elements is configured to connect a first element of a space structure to a second element of the space structure. Each of the first and the second tape spring elements is movable from a folded state into an unfolded state by releasing stored strain energy, to deploy the first and the second element of the space structure. The first tape spring element is connected to a first direct current source and configured to conduct direct current of a first polarity supplied to the first tape spring element from the first direct current source. The second tape spring element is connected to a second direct current source and configured to conduct direct current of a second polarity, opposite to the first polarity, supplied to the second tape spring element from the second direct current source.

A plain bearing comprising a generally cylindrical sidewall having a first axial end and a second axial end; and a curved portion disposed at the first axial end, wherein the generally cylindrical sidewall has a thickness, wherein the curved portion has an effective material thickness, wherein the effective material thickness of the curved portion is n-times thicker than the thickness of the generally cylindrical sidewall, and wherein n equals 2, 3, 4, or even 5.

A method for installing a multiple axis adjustable pivot bearing assembly, comprising: Installing and adjustment-pivot unit: using bolts or screws to install a pivot floor mount, comprising a pivot floor mount aperture and a slot, to a floor, sliding a pivot square nut with a pivot square nut aperture into the slot such that the pivot square nut aperture is aligned the pivot floor mount aperture, place a pivot cover, comprising a pivot cover aperture, over the pivot floor mount, such that the pivot square nut aperture, the pivot floor mount aperture, and the pivot cover aperture are aligned so as to receive a lower portion of a pivot bolt, installing the pivot bolt into the pivot square nut aperture and through the pivot floor mount aperture and the pivot cover aperture, such that a pivot disk, which is part of or assembled to the pivot bolt, is partially in a recess feature of the pivot cover, installing a height-adjustment nut onto an upper portion of the pivot bolt above the pivot disk, placing a pivot mount block onto the now assembled adjustment-pivot unit; and mounting a door onto the pivot mount block by attaching a door frame onto the pivot mount block.

An adjustment system comprising: a pivot nut comprising a pivot nut aperture feature configured to accept the lower portion of a pivot bolt; a floor mount having a slot in which the pivot nut is slidingly engaged so as to have, e.g., simultaneous movement including forward-backward, side-to-side and rotational and axial articulation, the floor mount having a floor mount aperture that aligns with the pivot nut aperture; and a cover configured to mount over the floor mount and engage with the pivot nut so as to move with the pivot nut.
