Parker's 404LXR is a slotless, brushless linear servo motor/square rail bearing positioner housed within a high strength, extruded aluminum body with magnetically retained protective seals.
The positioner is powered by a single rail of high energy rare earth magnets. Load bearing members provide heavy load and moment capacity, dynamic stiffness and precise straightness and flatness of travel.

The positioner’s integral linear encoder provides high precision, non-contact positional feedback with selectable resolutions from 0.1 to 5.0 microns.
The positioner is also offered with inductive proximity limit & home sensors, a “Quick Connect”, extended life, and a cable transport system.
