Rotation and Linear Drives and Motions

Many vacuum processes require a sample or other components to be moved around the vacuum system. VACGEN offer a comprehensive range of rotation and linear drives including wobble sticks, magnetic probes, rotary platforms and feedthroughs to ensure reliable and precise motion control.

Our vacuum drive and motion options include:

UHV Linear Drives

UHV Rotary Drives

Wobble Sticks

Linear drives can be used for a range of applications requiring small distance travel within a vacuum system, such as moving electron optics or apertures, source movement, or stage alignment. Our range of UHV linear drives utilise high quality edge welded bellows and have a linear motion range from 25mm to 150mm. Our drives can be manually operated or motorized. Rotary drives are used where a vacuum process requires a sample or components to be accurately rotated within the vacuum chamber. This can range from something as simple as spinning an attenuating chopper wheel, to accurately moving a sample to face from one analyser to another. Wobble sticks enable simple hand operated movements to be transmitted through the wall of the vacuum vessel. All our wobble sticks are mounted onto a 70mm OD flange and are capable of being baked without dismantling. They are ideally located at all interchange points in the vacuum system, where a sample must be transferred, for example, between a transport device and a sample holder. Wobble sticks can also be used as actuators to operate mechanisms inside the vacuum system, for example probe adjustment, variable orifices, or apertures.

Magnetic Transfer Probes

Non-Magnetic Transfer Probes

Rotary Platforms

Magnetically coupled probes contain samarium cobalt magnets for high-power, smooth transfer and, owing to their all-metal construction, are bakeable to +250°c. The transfer probes are used for transferring samples quickly between vacuum chambers The linear rack and pinion design of our non-magnetic transfer probes provide an extremely accurate method of linear travel within the chamber, with an optional secondary rotation shaft for azimuthal movement. These transfer devices are designed for applications precise transfer with a direct coupling for transferring higher loads.
Rotary platforms provide a means of rotational translation with a central clear bore. Differentially pumped rotary platforms are construction to enable a probe or similar device to be inserted into a UHV environment and rotated.

Z Axis Linear Transfer

Hollow linear drives are used when a probe or source requires positioning within the chamber with a high degree of accuracy. The Z axis only translators can all be fully motorised to give even higher degrees of accuracy.
