Abstract
An assembly comprising: a powder metal outer part (22) having a radially inward facing cylindrical surface (54) with a plurality of facets (52) formed thereon that, in an alternating fashion, extend in an axial direction from an axial side of the powder metal outer part toward an opposite axial side of the powder metal outer part to a position between the opposing axial sides of the powder metal outer part; a powder metal inner part (20) having a radially outward facing cylindrical surface with a plurality of facets formed thereon that, in an alternating fashion, extend in an axial direction from an axial side of the powder metal inner part toward an opposite axial side of the powder metal inner part to a position between the opposing axial sides of the powder metal inner part; and an intermediate component (26) disposed between the cylindrical surfaces of the powder metal outer part and the powder metal inner part that connects the powder metal outer part and the powder metal inner part together.
