A suspension thrust bearing device for use with a suspension spring in an automotive suspension strut of a vehicle. The device provides a bearing having upper and lower annular bearing members in relative rotation, and a damping element made of resilient material and interposed between the lower annular bearing member and the suspension spring. The damping element including at least one deflecting flange for reducing any ingress of water and other pollutants between the upper and lower annular bearing members. The damping element is provided with an annular groove open axially towards the suspension spring, the annular groove radially defining a spring support surface on an inner side, and the deflecting flange on an outer side. The deflecting flange has a frustoconical shape directed axially towards the suspension spring.

A mirror device includes: a mirror having a rotation shaft and a reflecting surface that reflects display light; a support portion having a cylindrical shape, having a base end fixed and a tip end being a free end, and configured to rotatably support the rotation shaft; and a motor that pivots the mirror, in which the rotation shaft is inserted into the support portion while spreading the support portion outward in a radial direction, and is slidably supported by the support portion.

Provided is a slide bearing capable of sustaining sliding performance over long period.

A slide bearing has an upper case (2) configured to be attached to an upper support for attachment of a suspension to a vehicle body, a lower case (3) rotatably combined with the upper case (2) to form an annular space (7); and an annular center plate (4) and an annular sliding sheet (5) both placed within the annular space (7). The center plate (4) includes a bearing surface (40) slidable with the sliding sheet (5) and an annular groove (42) formed on the bearing surface (40) so as to hold lubricant. The annular groove (42) has an inner circumferential surface (43a) inclining down from the opening section toward the groove bottom section as it goes outwardly in the radial direction and an outer circumferential surface (43b) inclining down from the opening section toward the groove bottom section as it goes inwardly in the radial direction. A line P of intersection between the inner circumferential surface (43a) and the outer circumferential surface (43b) is located closer to the bearing surface (40) than to a back face (41) of the center plate (4).

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.

An assembly and a method for manufacturing an assembly for transmitting torque to an aircraft actuator. The assembly and method include a torque tube having a longitudinal axis and an end fitting. The ending fitting includes a connector portion and an engagement portion that is inserted into the torque tube. The engagement portion includes a first end adjacent the connector portion, a second end opposite the first end, and a coupling region between the first and second end that includes an outer coupling surface having an outer diameter and a continuous groove formed thereon. The continuous groove includes two axial grooves that extend along the outer coupling surface along the longitudinal axis and a first parallel groove that extends circumferentially about the longitudinal axis along the outer coupling surface that joins the two axial grooves.
