Abstract: A spherical bearing with selectable electrical conductivity includes a bearing body having a spherical supporting surface, a layer of electrically insulating material and a housing having a concave spherical seating surface which form a ball joint having a center around which the bearing body may swivel relative to the housing when the housing is not clamped against the insulating layer and bearing body with the force required for operation of the bearing. A first positioning pin of electrically conductive material projects radially through the insulating layer and into a recess formed in the housing. Electrical connection between the housing and the bearing body is provided by a compression spring which bears against the recess and the first positioning pin. A second positioning pin of electrically insulating material may be selected in lieu of the first positioning pin and spring to provide a bearing configuration wherein the body is insulated from the housing.
