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



The SAG Series Built-In Guideway Ball Screw Linear Actuator delivers high-precision positioning, superior rigidity, and smooth linear motion for demanding industrial automation applications.

Engineered for high-duty multi-axis positioning systems, the SAG Series features an integrated internal linear guide rail combined with a precision-ground ball screw drive. Its high-rigidity structural profile minimizes overall module height while offering exceptional resistance to overhang and moment loads. This makes it an optimal motion solution for Cartesian gantry robots, high-speed pick-and-place equipment, automated optical inspection (AOI), precision dispensing, and heavy-payload transfer across electronics, semiconductor, and general manufacturing lines.

Key Features & Advantages

  • Built-In Guideway Architecture: Integrates the linear guide track directly into the base structure, maximizing mechanical stiffness and reducing total height.
  • Precision Ball Screw Drive: Achieves micro-positioning accuracy, low axial play, and high mechanical transmission efficiency.
  • High Moment Load Capacity: Designed to withstand complex multi-axis bending moments and heavy offset loads during dynamic travel.
  • Flexible Motor Adapter Design: Easily supports direct inline and parallel motor foldback mountings for major servo and stepper motor brands.
  • Integrated Sensor Channels: Embedded side slots allow clean, flush placement of magnetic limit and home positioning sensors.

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