Dual Shaft Wobblestick Manipulators
Since 1996, Ferrovac magnetically driven wobblestick manipulators define the benchmark for delicate and precise manipulations in ultra high vacuum systems.
Due to the principle of magnetic force coupling, the motion of the shaft is not affected by the difference between atmospheric pressure and ultra high vacuum. The operator can guide the shaft of the wobblestick nearly force-free in a smooth and controlled way.
Magnetic coupling also minimizes the risk for leaks and ensure longer lifetimes compared to conventional wobble sticks employed with long bellows stacks for linear motion.
Magnetically driven wobblestick manipulators always allow for continuous rotation of the shaft.
