Heavy duty rotary indexing drive
VG Scienta

Many vacuum processes require a sample or other component to be rotated. 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. VG Scienta have a wide range of rotary drives to fulfill most customer requirements.

Rotary Actuation Methods
There are several different methods of achieving rotation in vacuum. The two most common arrangements are:
A vacuum-tight seal on a mechanical drive that moves through the vacuum wall
or
A magnetic coupling that transfers motion from air-side to vacuum-side.

The more standard versions are discussed in this section but please bear in mind that we create a large number of custom rotary drives for many different applications, so please contact our sales department if you feel you have a requirement that is not covered in this section.

All the drives contained in this section cover different aspects of in-vacuum rotation. These range from simple manual drives with relatively low resolution and torque capacity to high performance drives that are capable of carrying high loads or have high speed or torque specifications. Many of these can be motorised with stepper or DC motors; they are listed as order code options where available.
