Air-Bearing IGM System
Air-bearing Integrated Granite and Motion (IGM) systems are ideal for high- and ultra-high performance applications. The multi-axis air-bearing system shown utilizes IGM design concepts with precision granite air-bearing surfaces, as well as encoders and linear motors mounted directly to the granite structure, resulting in a motion platform with less overall workpoint-to-granite height than a traditional stage-on-granite system.

Air-bearing Integrated Granite Motion (IGM) systems are ideal for high- and ultra-high performance applications. The multi-axis air-bearing system shown utilizes IGM design concepts with precision granite air-bearing surfaces, as well as encoders and linear motors mounted directly to the granite structure, resulting in a motion platform with less overall workpoint-to-granite height than a traditional stage-on-granite system.
Because they are specifically engineered to meet a customer’s application requirements, IGM motion systems represent the pinnacle of design flexibility. From drive and bearing type selection to system layout and arrangement, IGM systems are available with a wide variety of value-adding accessories and state-of-the-art control electronics. Aerotech’s motion engineers regularly custom-tailor IGM systems to meet unique technical and commercial application requirements.
The integrated nature of an IGM results in unique technical benefits. The granite structure is able to offer increased stiffness over traditional stages in certain situations, contributing to improved dynamic performance. Further, the simplified structural design serves to reduce the axis profile and minimize design offsets, resulting in a reduction in Abbe errors and therefore more accurate motion at the desired workpoint.
