GAO GONG GTH14A Series Semi-Closed Ball Screw Driven Linear Actuator

High-Rigidity Ball Screw Linear Stage with Dual Guide Rails

GAO GONG GTH14A series represents the pinnacle of high-precision linear motion. Also known as a Ball Screw Linear Module or Electric Linear Actuator, this series integrates dual high-rigidity linear guides into a compact, semi-sealed aluminum chassis to deliver exceptional payload capacity, outstanding moment resistance, and long-term positioning reliability.

1. Key Features & Product Advantages

• Integrated Dual Rail Design
  Built with two high-rigidity linear guides (15x12.5 - 2 rails), providing superior mechanical stability, excellent straightness, and high moment load resistance compared to single-rail alternatives.

• High Payload & Heavy-Duty Performance
  Engineered to tackle demanding automation tasks, supporting a maximum horizontal payload of up to 120 kg and a vertical payload of up to 50 kg.

• ±0.01 mm Repeatability
  Driven by a premium C7 grade 20mm diameter ball screw, ensuring sub-millimeter precision (±0.01 mm) for high-frequency, accurate positioning.

• Semi-Closed Protective Design
  The semi-sealed aluminum body protects internal components (ball screw and linear guides) from dust and debris while maintaining an optimized, cost-effective, and easy-to-maintain structure.

• Flexible Motor Mounting Configurations
  Supports direct-coupling and multiple multi-directional motor folding options (Left, Right, Lower side, or Exposed) to accommodate highly restricted machine spaces.

2. Technical Specifications

The following parameters represent the standard engineering limits of the GAO GONG GTH14A Series:

Note: The stroke range is available from 100 mm to 1250 mm in 50 mm increments. Standard motor options include 400W servo motors from Panasonic, Mitsubishi, Delta, and other major brands.

5. Industrial Applications

Thanks to its heavy-payload capability and dual-rail stiffness, the GTH14A series is widely applied by global system integrators in:

• Lithium Battery Production: High-speed pick-and-place, battery cell stacking, and sorting lines.

• Automated Assembly Lines: Multi-axis Cartesian robots (XYZ gantry systems) for precise industrial material handling.

• Precision Dispensing & Screwdriving: Smooth and highly accurate continuous path tracking for automated gluing, sealing, and fastening robots.

• Laser Cutting & Marking Equipment: High-stability motion guide for laser heads requiring consistent speed and zero backlash.
