Description
QRCZP (IEC) series is a B14 small-flange mounted helical gear reducer equipped with an IEC-standard motor interface and shaft-input configuration (Z type). Designed for compact mechanical layouts, the QRCZP unit allows direct installation of IEC motors using a B14 small flange, reducing space requirements while ensuring strong structural rigidity and high transmission efficiency.
Built on the QRC platform, the QRCZP series features precision-ground helical gears, carburized & hardened tooth surfaces, and a lightweight aluminum housing for excellent reliability, reduced noise, and long service life. Its modular design supports multiple output shaft configurations and flexible mounting positions, making it suitable for a wide range of industries including textiles, food processing, ceramics, logistics, packaging, plastics, and automation machinery.

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.
