The ABG10000 air-bearing gantry puts Aerotech’s core technologies and extensive manufacturing capability to work for you, providing outstanding performance and versatility in a wide range of automation applications. These systems are used in applications such as high-speed pick-and-place, automated assembly, vision inspection, dispensing stations and high-accuracy inspection.

Linear Motor/Linear Encoder

Aerotech’s high-performance BLM series brushless linear servomotors drive the ABG10000 to speeds of 1 m/s and accelerations of 0.5 g. Feedback is from a rugged noncontact optical linear encoder.

Air-Bearing Design

The ABG10000 incorporates an active preload on both vertical and horizontal surfaces. The opposing thin-film pressure maintains the bearing nominal gap tolerance. This design, in addition to the large air-bearing surface that distributes the load over a large surface area, results in a stage with outstanding stiffness that is ideal for heavy or offset loading.

Proprietary manufacturing techniques result in a stage with unsurpassed geometric characteristics. The air bearing has an inherent averaging effect that maximizes performance. The thin film will fill small surface voids and allow for other irregularities. This characteristic yields superior pitch, roll, yaw, straightness and flatness specifications.

Rugged Design

Since the linear motor is a noncontact device there is no backlash, wear or maintenance. The air bearings are magnetically preloaded and assembled to provide optimized stiffness and load distribution.

Cable Management System

Extensive R&D has resulted in an optimized cable management system (CMS) that has been field-proven to be the industry’s most reliable design. Large bend radii and high-flex cables ensure that the air-bearing gantry provides millions of cycles of maintenance-free operation. In the unlikely event of a component failure a modular design ensures that part replacement is fast and easy.

Turnkey Operation

Aerotech’s years of experience manufacturing precision positioning and control systems can be leveraged by acquiring a turnkey system. Typical options include a Z stage, vibration isolation, machine base and a control enclosure. Aerotech also manufactures a wide range of high-performance amplifiers and advanced motion controllers that are optimized for use with the ABG10000.

Custom Designs

Aerotech has engineered and manufactured custom high performance systems to meet customers’ needs and specifications for a variety of applications. We can draw on our vast motion control and positioning system experience to produce the ideal solution for your application.
