QRCHS Shaft Input Foot-Mounted Helical Gear Unit
QRCHS Shaft Input Foot-Mounted Helical Gear Unit
Features
- Shaft input configuration for direct mechanical coupling
- High-efficiency helical gear transmission
- Reinforced bearings for improved radial and axial load capacity
- Foot-mounted design for stable installation
- Aluminum alloy housing for lightweight and corrosion-resistant performance
Description
QRCHS series is a shaft-input, foot-mounted helical gear reducer engineered for industrial applications requiring stable torque transmission, compact structure, and flexible integration. As part of the QRC helical gear family, the QRCHS model uses a solid shaft input (HS type), enabling direct coupling with external drive shafts, pulleys, belts, or chain-driven systems.
Featuring precision-ground helical gears, carburized & hardened tooth surfaces, and a lightweight yet rigid aluminum alloy housing, the QRCHS reducer ensures smooth operation, reduced noise, and extended service life. Its foot-mounted base makes it easy to install on machinery foundations or machine frames, offering excellent mechanical stability.
The QRCHS series is widely used in textile machines, food processing lines, ceramic machinery, packaging equipment, logistics conveyors, plastics processing, and general industrial automation.

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.
