Multi-Axis Capabilities

The ANT rotary stage series is designed for compatibility and easy integration with Aerotech’s ANT linear stage product offerings. Together these stages provide accuracy, stability and small-size performance capability for almost any nanomanufacturing or inspection application.

Dynamic Performance

In addition to the high precision levels, these systems offer high dynamic performance and throughput ideal for disk drive manufacture and test.


The ANT rotary stage series was designed to operate in a 24/7 manufacturing environment. Unlike other rotary devices, the ANT rotary stage series requires no periodic maintenance, assuring years of trouble-free operation.
