Linear Motion Control – Vacuum Compatible Single Rail Stage!

Linear Motion – Single Rail Stages – SRS-008-04-020-01V

Santa Clarita, CA – Linear Motion Control – The SRS-008-04-020-01V vacuum compatible single rail positioning stage uses a brushless linear motor to generate a continuous/peak force of 20.6 lbs [91.6 N]/61.8 lbs [275 N] with a total stroke length of 8.3 in [210 mm]. The non-contact 1.0-micron resolution encoder allows for precise positioning. It is guided by a rigid recirculating ball linear bearing. There are also provisions that allow customer cables to be routed within the cable carrier. This single rail positioning stage has been manufactured using low-outgassing materials as selected by NASA in order to make it vacuum compatible. It has end-of-travel bumper stops. A home positioning sensor, end-of-travel-sensors, and custom mounting holes on the moving table are available upon request.For a detailed description of all the considerations taken when manufacturing a vacuum compatible system, please click here.
