Aerotech introduces the VTS300 vertical translation stage

Nov. 2, 2010
The VTS300 vertical translation stage from Aerotech, Pittsburgh, Penn., can position loads up to 450 kg (1000 lb) with ±25 µm accuracy in applications requiring a compact footprint with travels from 50 to 200 mm.

The VTS300 vertical translation stage from Aerotech, Pittsburgh, Penn., can position loads up to 450 kg (1000 lb) with ±25 µm accuracy in applications requiring a compact footprint with travels from 50 to 200 mm.

Applications range from step and settle placement to high force generation. Multiple units can be combined for lift and tip/tilt motion to provide a flexible, high performance, multi-axis motion solution. The stage positions extreme loads with 0.064 µm resolution.

The lead screw does not back-drive, which allows "set and forget" operation. The stage has ±10 µm bi-directional repeatability.

From the special high-stiffness aluminum-alloy base and table, to pre-loaded angular contact ball-bearings that support the 0.1 inch/rev lead-screw, each component of the VTS300 was chosen for use in applications requiring precision motion with extremely high loads.

VTS300 series stages are offered with matched stepping or NEMA 23 or 34 brushless servomotors that drive a high capacity 90° gearbox. Motors can be left-, right-, or rear-oriented.

In addition to movable limit switches to adjust travel range, vacuum preparation is available for operation in vacuum chambers from 10-3 to 10-6 torr.
