A bushing is provided for adjusting to differences in diameter between concentric elements of an assembly. The bushing may be provided with a plurality of leaf springs coupled to one another to form parts of a wall. The bushing wall may have a first contact face and a second contact face opposite the first contact face. The bushing wall may also be configured to be positioned in a generally annular shape. Each of the leaf springs forming part of the bushing wall may be radially deflectable relative to each of the other leaf springs in order to self-align the bushing by the resilient response of each leaf spring.

A motion guide device is formed of: a track member including a base portion extending along a longitudinal direction, and a pair of wall portions erected from both edges of the base portion in a width direction, and having rolling element rolling grooves formed along a longitudinal direction; and a moving member which is assembled in a movable manner along the longitudinal direction between the wall portions, and to which a pair of guide members are assembled, load rolling element rolling grooves which correspond to the rolling element rolling grooves being formed in the guide members, wherein at least either one of the guide members is equipped with a biasing member on a surface of the guide member on a side opposite to a surface of the guide member on which the load rolling element rolling groove is formed.

A device for adjusting a position of a furniture part on an item of furniture such that a closed position of the furniture part is predeterminable. The device includes an adjustment element for rotating a positioning default mechanism, and an abutment portion which interacts with an adjustment contour of the adjustment element. The adjustment contour extends as a spiral, by way of which a region of the adjustment contour and the abutment portion interact in such a manner that a stop of the device is slidable into a position, so that the closed position of the furniture part is predeterminable. The adjustment contour comprises a multi-edge portion with several surface portions which are aligned at an angle with respect to one another. The adjustment contour interacts with a counter portion on the abutment portion in such a manner that several predetermined rotational positions of the adjustment element are configurable.

The ball joint assembly includes a housing with an inner wall that surrounds an axially extending open bore. A ball portion of a ball stud is received in the open bore of the housing, and a shank portion of the ball stud projects out of the open bore. A pair of bearings are disposed in the inner bore of the housing and are interposed between the ball portion and the inner wall. Each bearing has a curved bearing surface which slidably contacts the ball portion for allowing the ball stud and the housing articulate relative before use. Each bearing also has an outer surface that slidably contacts the inner wall. A pair of biasing elements bias the bearings in opposite directions against the ball portion of the ball stud such that the ball stud is movable relative to the housing in the axial direction before use of the assembly.

Herein disclosed is a centrifugally cast pole having a substantially uniform wall thickness along the long axis of the pole. During centrifugal casting, molten metal is poured inside a rotating, tapered mold. As chilled liquid is poured over the outside of the rotating mold, the metal forms, or paints, to the contour of the mold interior creating a metal pole. By precisely controlling casting gyrations such as the spin, travel, pitch, and yaw of the rotating mold and the calibration and physical mechanisms of the casting machine, hollow, tapered, tubular metal poles are produced with previously unknown uniformity of wall thickness. The controlling principles, designs, and mechanisms of this centrifugal casting method enable wall uniformity to extremely high tolerances. By extension, the ability to precisely control the metal volume painted inside the mold allows, as a design choice, wall thickness variation in any embodiment if so desired.

A composite wear pad for being coupled to a slider block of a convergent nozzle of a gas turbine engine includes a high heat capacity composite having a resin and a plurality of carbon fibers bonded together by the resin. The composite wear pad also includes a first rod coupled to the high heat capacity composite at a first axial end of the composite wear pad such that a first end thickness. The composite wear pad also includes a second rod coupled to the high heat capacity composite at a second axial end of the composite wear pad such that the first axial end and the second axial end of the composite wear pad each have an end thickness that is greater than a middle thickness of the composite wear pad.

The present disclosure relates to a slide block, the slide block assembly having a ball bushing bearing may include: a slide block which has formed at one side thereof a guide receiving part capable of receiving a slide guide of which at least a portion is formed as a linear section or a curved section; and a ball bushing bearing of which the inner surface is formed so as to correspond to the slide guide so as to be capable of making sliding contact with the slide guide, and the outer surface is formed so as to correspond to the guide receiving part so as to be capable of making rolling contact with the guide receiving part by means of a ball method.

A strut assembly includes a piston and a bearing housing around the piston. The bearing housing may also comprise a groove and a tapered surface opposite the groove. A bearing may be in the groove and proximate the piston. An outer cylinder may be around the bearing housing. The angle of the tapered surface may be based on a deflection angle between the outer cylinder and the piston. A wear plate may be around the tapered surface. An elastic material may be disposed between the tapered surface and the wear plate. The bearing housing may comprise a titanium alloy. The bearing housing may be configured to flex towards the wear plate.

An assembly including an inner component; an outer component; a tolerance ring, comprising an annular band and a plurality of projections projecting radially from the annular band, the tolerance ring being disposed between the inner component and the outer component; and a low friction layer provided radially inside or radially outside the annular band so as to enable sliding movement in an axial direction between the inner component and the outer component, wherein at least one of the inner component or outer component is profiled to transmit a radial load between the inner component and the outer component to appreciably prevent collapse of the projections.

A composite wear pad for being coupled to a slider block of a convergent nozzle of a gas turbine engine includes a high heat capacity composite having a resin and a plurality of carbon fibers bonded together by the resin. The composite wear pad also includes a first rod coupled to the high heat capacity composite at a first axial end of the composite wear pad such that a first end thickness. The composite wear pad also includes a second rod coupled to the high heat capacity composite at a second axial end of the composite wear pad such that the first axial end and the second axial end of the composite wear pad each have an end thickness that is greater than a middle thickness of the composite wear pad.
