XLA™ Linear Actuators
The XLA™ Linear Actuators are the most robust of all standard Signature Motion stages to date! There are two standard frame sizes including the XLA™ 9 and the larger XLA™ 15.
The XLA™ actuators were designed as standalone Y-axis motion stages for gantry applications and they are extremely rigid, eliminating the cost of structural support over longer spans. They are constructed for a wide variety of applications requiring ultra-high capacity in a compact envelope and can provide exceptional structural strength even when used without support. The linear profile rail guides and ball screw drive mechanism provide very accurate and repeatable motion.
Overview
• Ball Screw Drive and Profile Rail Linear Guides
• Low Coefficient of Friction
• Solid and Stiff Construction Materials
• Precise and Repeatable
The XLA™ 9 has a static capacity exceeding 3,500 lbs. and a dynamic capacity of more than 2,300 lbs. based upon 2 million inches of travel life in a unit with an envelope of 1.99" tall and 3.75" wide.
The XLA™ 15 has a static capacity exceeding 14,000 lbs. and a dynamic capacity of more than 9,500 lbs. based on 2 million inches of travel life in a unit with an envelope of less than 3" tall and 6" wide.
Moment Load Compensation™ negates the effects of applied moment, instead making offset loads into an equivalent vertical load. Moment Load Compensation™ makes slide life easy to calculate and consistent.

Rigid Construction
The XLA™ actuators are built using compact T-slot aluminum extrusions that are designed to provide exceptional structural strength even when used without support. The XLA™ series is seen as a solution to cross-axis applications where the rigid extrusion enables the actuator to become a structural member of the machine without the need for expensive base mounting structures. This feature makes the XLA™ perfect for a cross-axis, or Y-axis, on gantry applications.
Adaptable
All XLA™ series products incorporate T-slot channels along the full length of the base. This bilateral channel allows for quick and easy adjustment of limit switches and other peripheral add-ons. The channels located on the underside of the base are configured to allow for simplified mounting into an X-Y configuration. Multiple axis units can be easily joined without the need for additional mounting plates. The mounting holes in the XLA™ carriage match mounting holes in the XLA™ base. The XLA™ can be mounted in X-Y and Z configurations with the optional Z bracket.
A close examination of the top carriage mounting pattern reveals a unique top-down or bottom-up mounting method to make attachment of your devices to the XLA™ a simple, versatile process.
Environmental Compatibility
The XLA™ actuators incorporate an anodized 6061-T6 aluminum base and are constructed with carbon steel screws, fasteners and components. Stainless steel options are available. Upon special request, XLA™ can be configured with a stainless steel ball screws, profile guide rails, and end support bearings for additional environmental corrosion resistance.
