This item is a pre-owned Ferrotec Ferrofluidics Inertia Damper.
Unit is in excellent condition!
This piece was tested and working just prior to being placed in inventory at our warehouse.

From product website: A stepper motor operated at its natural frequency may experience excessive settling time, vibration and acoustic noise. A Ferrofluidic damper relies on ferrofluid to absorb the motion energy by a shearing effect which produces a torque that opposes the unwanted oscillatory motion. A Ferrofluidic damper is hermetically sealed and has a non-magnetic housing which attaches to the motor shaft. Inside the housing is an inertial mass which levitates on Ferrotec’s ferrofluid, thus eliminating the need for bearings to support the mass. A Ferrofluidics damper offers reliable damping and accurate performance with no losses in speed or accuracy, and no reduction in torque. Other performance benefits include:
– increased positional accuracy
– reduced settling time.
– reduced torsional oscillations
A Ferrofluidic inertia damper is easily attached to the motor shaft and has no maintenance requirements. It can be custom tuned to your system for optimum results. Typical applications include X-Y-Z Plotters, Printers, Optical Scanners, Robotics and Milling Machines.

Size:
– 3.2″ diameter, 2.2″ height, for 3/8″ diameter motor shaft.
