Abstract
A bearing including a generally cylindrical sidewall including an electrically conductive substrate, and an electrically non-conductive or low-conductive sliding layer coupled to the substrate, where the generally cylindrical sidewall includes a plurality of protrusions protruding radially inward or radially outward from a bore defining a central axis, where at least one protrusion 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, and wherein at least one protrusion has a spring rate of not greater than 30 kN/mm, such as not greater than 25 kN/mm, such as not greater than 15 kN/mm, or such as not greater than 10 kN/mm.
