Precise, rugged linear stages

Precise, rugged linear stages With a ruggedised and fully sealed design, Aerotech's ALS5000 series linear stages combine direct-drive motor technology and linear motion guide bearings, for high precision positioning of large payloads in harsh production environments. The range is available in a choice of widths: the ALS5000 series (279mm wide) has seven travel range options from 200mm to 1000mm, whilst the ALS500WB series (571mm wide) has five travel range options 450mm to 1000mm. The wide base version is designed to facilitate X-Y mounting and accommodate larger offset stage loading. It also includes a dual linear motor drive to provide the extra power needed for high speed positioning. The ALS5000 design allows its use in the most demanding production application environments. Protecting the stage from hot sparks and debris, the hard top and integral metal waycovers have a Teflon impregnated hard-coat finish for maximum durability and scratch resistance. A unique, tensioned side-strap seal allows free travel of the tabletop whilst maintaining a tight seal - further protecting the stage bearing, motor and encoder. An optional air-purge feature allows air or specialist gases to be forced into the interior of the stage causing a positive pressure and ensuring that the stage is totally sealed against particle ingress.
