Have remainder parts being sourced at the moment from the guys at Modatek.

'Roller damper' is the colloquial name for a Salomon type centrifugal pendulum absorber.
It consists of a flange with equi spaced holes about the CL of the shaft in which the rollers (similar to a roller bearing element, but usually made of a high density metals such as tungsten) lie. Their axes are parallel to the shaft axis and they are free to orbit within their bores once the centrifugal force overcomes gravity. The axial motion is constrained.
They are sometimes used between ball screw and motor in the form of an elastomer coupling. I would think the torsional vibration would be greater however with a stepper as opposed to a servo due to how a stepper works and its positioning via step pulse, or micro steps. This vibration can sometimes show itself with rack and pinion stepper drives too, but in a lot of cases with racks and indeed ballscrews a toothed belt drive is an easy dampening option - it can also help too with packaging length.
