NDJ Worm Gear Screw Jack
NDJ Worm Gear Screw Jack
Description
NDJ Series Worm Gear Screw Jacks are precision linear motion actuators designed for heavy-load lifting, positioning, and synchronization applications. Built with a worm-gear transmission and trapezoidal (T-type) screw, the NDJ series delivers stable load handling, high mechanical reliability, and long-term durability.
This product line supports multiple capacities ranging from 0.25T to 30T and offers a wide selection of configurations, including translating and rotating screw types, upward or downward mounting orientations, anti-rotation mechanisms, protective sleeves, and nine different screw-tip end forms. The modular design allows users to customize stroke, installation styles, and directional options—achieving precise motion control in diverse industrial environments.
With flexible assembly types (A / B), anti-rotation options (F, Z, X, Q), and multiple shaft-direction codes (A / B / C), the NDJ worm screw jack can seamlessly integrate into complex mechanical systems such as lifting platforms, automated lines, and synchronized multi-jack systems. It is engineered to operate safely under high loads while requiring minimal maintenance.

FAQs
Does NUODUN support non-standard customization? What is the typical lead time?
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.
How does NUODUN ensure high precision and reliability in customized transmission systems?
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.
Which industries commonly use NUODUN transmission components?
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.
How does NUODUN guarantee long-term product reliability?
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.
Does NUODUN provide global after-sales support?
Yes. We offer remote technical support, installation guidance, troubleshooting, selection assistance, and long-term spare parts support for OEM/ODM partners.
