Aerotech intros non-contact, direct-drive linear air-bearing stage
The ABL1500 non-contact, direct-drive linear air-bearing stage delivers fully active pre-load for semiconductor, data storage, and medical device applications. A brushless linear servomotor with an ironless forcer for zero cogging drives the stage, with no attractive forces. A large air-bearing surface with opposing thin-film pressure accommodates heavy or offset loads. The thin film fills small surface voids and allows for other irregularities.

PRESS RELEASE
NON-CONTACT DIRECT-DRIVE LINEAR AIR BEARING STAGE FOR HIGH PERFORMANCE SCANNING AND INSPECTION
New ABL1500 from Aerotech exceeds capability of ball-screw and mechanical-bearing systems
The ABL1500 direct-drive linear air-bearing stage from Aerotech meets the needs of demanding scanning and inspection applications with fully active pre-load, high stiffness and unsurpassed geometric characteristics. Its positioning tolerances exceed the capability of conventional ball-screw and mechanical-bearing systems. The non-contact design assures years of maintenance-free operation.
The stages are appropriate for critical applications in any industry that requires exceptionally smooth and accurate linear motion to manufacture, test or inspect a product. These include semiconductor, data storage, medical and genome devices and any industries requiring cleanroom operation.
The stage is driven by a brushless linear servomotor with an ironless forcer for zero cogging, and no attractive forces, resulting in unsurpassed smoothness of motion. Because there is no mechanical contact between moving elements, the stages experience no wear or performance reduction over time. Service life is virtually unlimited with no lubrication.
A large air-bearing surface with opposing thin-film pressure accommodates heavy or offset loads with high acceleration and accuracy. The thin film fills small surface voids and allows for other irregularities, yielding superior pitch, roll, yaw, straightness and flatness specifications.
Aerotech (www.aerotech.com) is a leading supplier of motion control products to industry, government, science and research institutions around the world. Its precision products provide critical performance for demanding applications requiring high precision, high-throughput motion control solutions.
