The Ferrovac Magnetically Coupled Wobble Stick

Magnetic coupling as the driving principle for wobble sticks was introduced by Urs Maier in the early 1990's. Since then, Ferrovac magnetically driven wobble stick 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.

**Beware of cheap copies**

In recent years, the proven Ferrovac design has been copied by many of our competitors. While admittedly some of our competitor's wobble sticks are well made, others may not fulfill your expectations in terms of degassing, long lifetime and smoothness of motion. Note: We are servicing and refurbishing Ferrovac wobblesticks dating back to the years when we first introduced the design
