Description
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.

FAQs
Yes. NUODUN’s core competitiveness lies in the synergistic advantage of “customization + system integration.” We support structural customization, torque customization, input flange customization, mounting interface customization, stroke customization and more for products such as planetary gearboxes, screw jacks, electric cylinders, and gearboxes. The typical lead time for standard non-standard customization is 7–20 days, while more complex engineered projects are usually delivered within 3–6 weeks.

Our engineering strength comes from long-term R&D investment, CAE simulation, lifetime calculation databases, modular design frameworks, and a mature testing/verification system. This ensures that every customized solution is not only manufacturable, but also reliable under real-world loads — balancing precision, durability, and cost efficiency.







Our products are widely used in photovoltaic manufacturing, semiconductor equipment, automotive production, metallurgy, logistics, medical devices, aerospace, stage automation, and industrial automation — especially where precision positioning, heavy loads, or long service life are required.
All products undergo type testing, torque testing, vibration testing, life testing, noise measurement, and precision inspection. Core components such as gears, screws, and bearings are produced using advanced machining, grinding, heat treatment, and automated assembly processes.
Yes. We offer remote technical support, installation guidance, troubleshooting, selection assistance, and long-term spare parts support for OEM/ODM partners.
