Technical Notes
Custom designs (non-standard stroke, force, or interface) are available upon engineering consultation.
Duty cycle: 100% (continuous operation)
Not self-locking—a motor brake or external locking mechanism is required for vertical or safety-critical applications.
For strokes >300 mm, verify column stability using the provided load-stroke curve.
For strokes >800 mm, telescopic and protective tube lengths are extended by 200 mm.

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.
