Wobble sticks

The UHV Design wobble stick is a slimline modular concept benefiting from UHV Design’s high power magnetic coupling technology. The coupling eliminates the need for long egde-welded bellows stacks, typically employed with conventional wobble stick designs.

This reduces the risk of leaks, particularly for deposition applications such as MBE where particulates or deposition between bellows convolutions can reduce lifetimes or cause immediate failure.

We have a range of Wobble Sticks specifically designed for common VT-SPM systems. Click here to learn more about our XWSG40 range.

XWSG40 range for VT-STM and VT-AFM applications

Our range of XWSG40 wobble sticks are compatible with leading VT-STM and VT-AFM systems. They have been designed to replace conventional wobble sticks that utilise multiple bellows and can be prone to accidental damage and premature failure.

Available with 180mm and 270mm stroke lengths and choice of in-line or right-angle flag grippers.

The XWSG40 utilises a magnetically-coupled shaft and a single bellows assembly to improve reliability and ease of use compared to the conventional wobble stick design. As the XWSG40 is magnetically-coupled there is no thrust due to vacuum.
