Linear stage
The ALS130 is a high-precision compact linear motor stage which uses a center-driven, non-cogging linear motor as the driving element. This design is said to eliminate the backlash, windup, and stiction which is normally associated with lead screw and ball screw drives. The product is available with either precision cross-roller or linear motion guide bearing systems.
