SAA Series Electric Actuator (Built-In Guideway Ball Screw Type)



The SAA Series Built-In Guideway Ball Screw Linear Actuator delivers reliable high-precision positioning, smooth velocity control, and robust mechanical stability for standard industrial automation applications.

Engineered for factory automation systems requiring dependable multi-axis positioning and repeatable motion, the SAA Series features an integrated internal linear guide rail profile combined with a precision ball screw drive. Its high-rigidity structure minimizes overall weight while maintaining strong mechanical resistance against deflection, making it an ideal motion solution for Cartesian gantry setups, pick-and-place systems, automated dispensing, vision inspection, and light-to-medium payload transfer across electronics, packaging, and general manufacturing.

Key Features & Advantages

  • Built-In Guideway Architecture: Integrated internal linear guide profile offers an optimal strength-to-weight ratio and simplified multi-axis assembly.
  • Precision Ball Screw Drive: Delivers consistent micro-positioning accuracy, low axial backlash, and high mechanical efficiency.
  • Smooth & Quiet Travel: High-grade internal guiding components minimize friction and vibration during high-duty cycles.
  • Versatile Motor Configuration: Easily accommodates inline and parallel motor mounting adapters for major servo and stepper motor brands.
  • Integrated Sensor Channels: Built-in side slots allow clean, low-profile placement of magnetic home and limit sensors.

The SAA Series Electric Actuator provides an adaptable, cost-effective motion control solution for production engineers and builders seeking uncompromised accuracy and long-term reliability.
