These novel damper rollers act to dissipate unwanted energy imparted to a body which is being moved along a rail while still providing the rolling function necessary to move the body along the rail. The roller structure comprises an inner wheel on which the body is mounted and an outer wheel around the circumference of the inner wheel and coupled to the inner wheel by a series of bands of metallic or elastomeric material which frictionally couple inner and outer wheels. The means for dissipating the energy is twofold: hysteretic damping provided by the distortion of the spokes in the inner wheel and through the dissipation caused by the scrubbing of the bands with respect to one another when the outer wheel becomes deformed with respect to the inner wheel.
