Rotation and Linear Drives and Motions
Explore VACGEN's selection of vacuum drives and motion options, including UHV linear drives and UHV rotary drives available to buy online. 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.

| 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. |
- 150mm Manual Z Movement Translator£3,850.00The TR is a long stroke Z-axis translator with 33mm clear bore, offering stable vertical or horizontal mounting. The support frame and guide bars ensure movement is accurate and rotation free. The design offers a wider selections of options including manual or motor driven options, three port feedthrough chamber and bellows support tube for mounting drives.
- Wobble Stick Manual 80mm Linear Travel Pincer Grip4 to 6 weeks delivery£3,080.00Pincer Grip Wobble are used where linear and angular movement is required to move a 14mm disk samples inside vacuum via an inline pincer grip. The pincer grip allows for four pre-set rotation position at 90 intervals. Edge welded bellows, gives the user a true 'feeling' of position inside the vacuum chamber to give a controlled positioning.
- Wobble Stick Manual 151mm Linear Travel Pincer Grip4 to 6 weeks delivery£3,520.00Pincer Grip Wobble are used where linear and angular movement is required to move a 14mm disk samples inside vacuum via an inline pincer grip. The pincer grip allows for four pre-set rotation position at 90 intervals. Edge welded bellows, gives the user a true 'feeling' of position inside the vacuum chamber to give a controlled positioning.
- Mechanical Hand Manual 80mm Linear & Rotatory Movement (No Jaws)4 to 6 weeks delivery£3,025.00Mechanical hands are used for transferring a sample where linear, angular and rotary movement is required. The pistol grip which actuates the movement and the use of edge welded bellows, gives the user a true 'feeling' of position inside the vacuum chamber to give a controlled transfer. These can be supplied with or without the pincer grip. If supplied with a pincer, these can be inline or perpendicular, with plain jaws or jaws to accept the flag style sample plate.
- Mag Drive Linear 305mm Travel 70mm OD Flange4 to 6 weeks delivery£3,685.00High power magnetically coupled precision linear travel with optional rotation. The MLD series offers linear only, where rotation is not required, or the MLRD series offers an independent 360° rotation shaft, where rotation is required. These only use UHV accepted metals within its construction. These probes have a front bearing housing supporting the linear shaft, which offers higher accuracy over the MLRV series for repeatability tasks. On the MLRD series, the independent rotation shaft also…
- Rotary Feedthrough Single Stage Coarse DN38CF4 to 6 weeks delivery£3,807.24Differentially Pumped Rotary Feedthroughs provides the means of translating rotation through a vessel wall without losing vacuum integrity, enabling probes to be inserted without effect on the chamber pressure. To maintain the rotary seal, one vacuum port is mounted to the base flange of the assembly allowing connection to an appropriate independent pump. These have a 25mm clear bore with coarse and fine control available in addition to motorised options.
- Rotary Drive 100mm Shaft Inline Stepper Motor Wired4 to 6 weeks delivery£3,325.20The RD6 is a manual or motorised precision rotary drive with a 100mm shaft length. The RD6 has low backlash, with a smooth continuous primary rotation via a 9.5 mm diameter shaft.
- Rotary Drive 256mm Shaft Manual R1 & R2 - Standard 12mm4 to 6 weeks delivery£3,630.00The RD2 has primary rotation with secondary linear movement for the Azimuthal rotation of the sample plate on the 12mm and 24mm versions of SH2 sample holders. The RD2 is a manual or motorised high precision rotary drive, with a 256mm shaft length. The RD2 is fitted with Index scale, rotation stops and position lock. We also offer a custom shaft extension with bearing housing to suit custom requirements. The RD2 is low backlash, with smooth continuous primary rotation via a 9.5 mm diameter…
