ABSTRACT:
A roller includes a rolling bearing having inner and outer rings, a roller shell formed of injection molding material and molded in a form-fitting manner onto the outer ring of the roller bearing, and a spindle disposed in the bore of the inner ring with a space being provided between the surface of the bore and the spindle. The spindle includes at least one form-fitting element. An injection molding material forms a filler in the space between the spindle and the bore surface, whereby the outside contour of the spindle is constructed as am outer shaping surface for the form tool. A method of producing a roller involves placing a rolling bearing having inner and outer rings into a form tool, placing a spindle in the form tool so that the spindle extends into the bore in the inner ring and is held in place in the form tool, closing the form tool, and injecting molding material into the form tool. The molding material flows into a space provided between the inner surface of the form tool and the outer surface of the outer ring to form a roller shell of the molding material that is molded in a form-fitting manner onto the outer ring of the rolling bearing. The molding material also flows into a space that exists between the inner surface of the bore and the outer surface of the spindle to fix the spindle relative to the inner ring.
