Abstract
A spin-through rod centralizer consisting of a stator mounted on the rod coupling which provides the bearing surface for rotation of the coupling within the stator. The stator is restrained from such axial movement by two steel 'washers' that are captured between the rod shoulders and the coupling when the connection between two rods is made up. The washers are slightly larger in diameter than the coupling and thereby keep the stator located on the coupling, yet do not restrict the relative rotation between the coupling and the stator. An alternative configuration uses a coupling with a shoulder at one end that acts as one of the 'washers' to restrain the stator from axial movement.
