NDB Series Worm Gear Screw Jacks are precision-motion lifting and positioning actuators designed for vertical lifting, lowering, pushing, tilting, and accurate height adjustment tasks. With a compact structure, low weight, and inherently safe mechanical design, the NDB series is highly suitable for applications that require reliable load handling and high positional accuracy.

Driven by electric motors, hydraulic systems, or pneumatic systems, the NDB series is especially optimized for motor-driven environments, offering smooth transmission, high repeatability, and stable performance in industrial automation settings.
The series provides a loading capacity range of 1–50 tons, with a duty cycle of ≤30%, making it suitable for both single-unit use and multi-screw synchronized lifting systems.

Highlights

• Versatile Lifting & Positioning
  Supports lifting, lowering, pushing, tilting, and multi-directional adjustment across a wide range of industrial applications.
• Compact & Lightweight Structure
  Simple mechanical design ensures easy installation, low maintenance, and stable long-term use.
• High Precision Positioning
  Particularly suitable for motor-driven systems requiring accurate and repeatable positioning control.
• Flexible Drive Options
  Compatible with electric, hydraulic, and pneumatic drives for broad system integration.
• Reliable Load Handling
  Designed for static and dynamic loads up to 50 tons, ensuring high safety and durability in demanding environments.
