- Extreme load carrying capability, up to 450 kg, in a compact package
- Small stage footprint
- High resolution to 0.064 µm
- Lead screw does not back-drive, allowing "set and forget" operation and excellent in-position stability
- Vacuum compatible
Aerotech’s VTS300 accurately positions loads up to 450 kg and the small volume allows the positioning of high loads in space-constricted applications. Typical applications range from step and settle placement to large force generation. Multiple units can be combined for lift and tip/tilt motion.
Outstanding Design and Construction Features
The VTS300 series stages incorporate the highest quality components to provide superior positioning performance over a long lifetime. The base and table are fabricated from high hardness, high stiffness special alloy aluminum.
Pre-loaded angular contact ball-bearings support the 0.1 inch/rev precision lead-screw. The table moves on linear motion guide bearings providing excellent payload capability and long-life, even with heavy offset loads. The linear bearings also provide outstanding accuracy as well as exceptional flatness and straightness specifications over the length of travel.
Angular contact ball-bearings transmit shear forces and support excellent translation characteristics even with heavy loads. The anodized tabletop has a steel insert to support a tooling ball upon which the load would rest, providing a point lift for tip/tilt configurations.
The VTS300 series stages are available with matched stepping or brushless servomotors. The motor drives a high capacity 90° gearbox.
Options Include Vacuum Preparation for 10-6 torr
A number of options increase the flexibility of the VTS300 series stages for a wide range of applications. Vacuum preparation for operation in vacuum chambers to 10-6 torr is available. The stage also has movable limit switches so that customers can adjust the travel range.
