Abstract
A device for maintaining rotors centered during spin testing thereof includes a disc-like or sleeve-like centering element positioned between the exterior of a spin arbor and the interior of an axial bore hole extending through the rotor under test. Specifically designed circumferential areas on the centering elements are elastically deformable in a radial direction to maintain contact with the rotor even when the bore hole thereof slightly expands by the centrifugal forces generated during the spin test.
