Abstract: An assembly including an inner member; an outer member; and a bearing including a bearing sidewall including a flat portion, a first convex axial end, and a second convex axial end, where at least one of the inner member or the outer member is adapted to axially translate relative to the bearing, and where at least one of the first convex axial end or the second convex axial end is adapted to induce formation of a film on the bearing sidewall during the axial translation of at least one of the inner member or the outer member.

Abstract: A bearing including a sidewall including an electrically conductive substrate, and an electrically non-conductive or low-conductive sliding layer coupled to the substrate, where the sidewall includes at least one circumferential rib feature protruding radially inward or radially outward from a bore defining a central axis, where the at least one circumferential rib feature has an aspect ratio between a circumferential length and an axial width of at least 2:1, where the circumferential rib feature is adapted to contact an opposing component such that at a point of contact the bearing has a void area free of sliding layer so as to provide electrical conductivity between the bearing and the opposing component.

Abstract: A linear motion assembly having a static coefficient of friction, μS, as measured between an inner component and an outer component, and a dynamic coefficient of friction, μD, as measured between the inner component and the outer component, wherein μS/μD is less than 2.0, such as less than 1.9, less than 1.8, less than 1.7, or even less than 1.6.

Abstract: A bearing including a bearing sidewall including a first circumferential end including an apex region, and a second circumferential end including a nadir region, where the first circumferential end and the second circumferential end are adapted to contact each other to form an interface, where at least one of the apex region or the nadir region includes a void to prevent contact between the apex region of the first circumferential end and the nadir region of the second circumferential end, where the bearing sidewall includes a substrate and a low friction material, and where at least one of the first circumferential end or the second circumferential end comprises an end face that is free of low friction material.

Abstract: A sliding material including: a substrate, and a textured sliding layer overlying the substrate, where the sliding layer includes asperities including a plurality of apexes and nadirs, where 1) the sliding layer has a root mean square gradient of less than 0.064; 2) the sliding layer has an apex material portion of less than 10%; 3) the sliding layer has a nadir material portion of less than 75%, and where the textured sliding layer induces formation of a film when engaged in a rotational interface w/ another component.
