Conductive bearing

The invention provides a bearing comprising a substantially cylindrical sidewall comprising a conductive substrate and a non-conductive or low-conductive sliding layer coupled to the substrate wherein the substantially cylindrical sidewall comprises a plurality of projections projecting radially inward or radially outward from a hole defining a central axis, wherein at least one projection is adapted to contact an opposing component such that the bearing has a void region free of a sliding layer at a contact point so as to provide electrical conductivity between the bearing and the opposing component, and wherein the at least one projection has a spring ratio 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. 本发明提供了一种轴承，所述轴承包括包含导电基底的大致圆柱形的侧壁以及联接至所述基底的非导电的或低导电的滑动层，其中所述大致圆柱形的侧壁包括从限定中心轴线的孔径向向内或径向向外突出的多个突出部，其中至少一个突出部适于接触相对部件，使得在接触点处所述轴承具有不含滑动层的空隙区域，以便在所述轴承与所述相对部件之间提供导电性，并且其中至少一个突出部具有不大于30kN/mm，诸如不大于25kN/mm、诸如不大于15kN/mm、或诸如不大于10
