Precision vertical lift table
max. 25 mm, max. 100 mm/s | AVL125 Series Aerotech

The AVL125 represents a significant breakthrough in vertical alignment of high-precision components. This unique device incorporates the best high-performance features: high speed (>100 mm per second), high resolution (9 nm), superior in-position stability, and high accuracy in one compact package.

Its superior noncontact linear motor drive employs a high-accuracy encoder for direct position feedback. When combined with Aerotech's MXH multiplier, it offers an industry-leading 9 nm resolution in addition to high speed and accuracy.

The design of the AVL125 provides vertical, elevator-like motion, often necessary in confined spaces. The horizontal payload-mounting surface gives designers clear access to all sides of the stage, which is important in automated handling of payloads by overhead robots.

Bearing elements are recirculating ball style for maximum stiffness and reliability. These are mounted on an optimized base and wedge assembly for stiffness and low mass/inertia, enhancing dynamic performance.

The critical elements of the AVL125 were selected to operate in a 24/7 industrial environment and, unlike screw- or piezo-based vertical stages, the AVL125 requires no maintenance and will assure years of trouble-free operation.
The AVL125 includes a pneumatic counterbalance to hold position against gravity with very little motor current. This minimizes thermal heating while holding position.
