Claim:
1. A method of manufacturing a tensioning roller or winder device, the method comprising: overmolding a pulley onto an outer ring of a rolling bearing such that the pulley extends radially outward from an outer surface of the outer ring, the overmolding process cohesively affixing an opening of the pulley onto the outer ring, the rolling bearing also including an inner ring and at least one row of rolling elements disposed between the inner ring and the outer ring, and the inner ring defining a bore surrounding a rolling bearing axis of rotation; selecting a first fixing screw having a first end and a second end from a plurality of fixing screws, each of the plurality of fixing screws having a different outer diameter; after selecting the first fixing screw, overmolding a cylindrical sleeve in the bore of the inner ring, the sleeve comprising a cylinder having a cylinder outer surface and a cylinder inner surface, the cylinder outer surface being cohesively affixed to the bore of the inner ring and the cylinder inner surface defining a cylindrical through bore having an inner diameter substantially the same as the outer diameter of the first fixing screw and having a first end and a second end; inserting the first fixing screw into the first end of the through bore so that the first end of the first fixing screw extends from the first end of the through bore and such that the second end of the first fixing screw extends from the second end of the through bore and such that a central portion of the first fixing screw is in direct contact with the through bore; and axially fixing the first fixing screw in the through bore.
