Abstract

A method for forming a clamping device comprising of a swiveling body made of plastic, a plain bearing bushing mounted radially inside the plastic swiveling body, a rolling bearing for mounting a clamping roll arranged eccentrically to the bearing bushing, the edges of the plain bearing bushing being wound out of a strip, and joined to each other under intrinsic tension in the area of the butt joint; and, wherein, the lateral surface of the plain bearing bushing and the bore surface of the rolling bearing function as parts of a mold for the injection-molding of the swiveling body and consisting of the steps of placing the rolling bearing assembly and a plain bearing bushing in a mold half in eccentric relation to one another, placing a second mold half over the plain bearing bushing and rolling bearing configured to form ring-shaped projections to hold rolling bearing in a predetermined axial position relating to the bearing bushing, and injecting a plastic material with the mold closed to form the swivel body.
