Air Bearing Stage - ABS-012-12-030-X

< Back to list
Air Bearing Stage,a linear motor,product,ABS-012-12-030-X The ABS-012-12-030-X is a low profile air bearing positioning stage uses a brushless linear motor to generate a continuous/peak force of 29.0 lbs [129 N]/87.0 lbs [387 N] with a total stroke length of 12.3 in [311 mm]. The non-contact 1.0-micron resolution encoder allows for precise positioning. It is guided by 5 flat magnetically preloaded non-contact porous carbon air bearings (flat air bearing) floating on a granite base with excellent flatness and straightness specifications. There are also provisions that allow customer cables to be routed within the cable carrier. It has end-of-travel rubber bumper stops. End-of-travel-sensors and custom mounting holes on the moving table are available upon request. This system has no wearing parts. It is ideal for applications that require frictionless motion with low velocity ripple.
