Hydro-Mec 211A - Single-Stage Helical Gearbox, 3.38:1 Ratio, Input 71B14, Output 71B14, Aluminium Housing
Manufacturer Profile – Hydro-Mec: Hydro-Mec is a European industry leader in high-performance gearboxes and gear motors. Renowned for their innovation, reliability, and modular systems, Hydro-Mec designs gear solutions for demanding industrial environments – offering technical precision and mechanical durability for sectors ranging from automation to heavy-duty processing.

Exceptional Efficiency (98%): With an operational efficiency of up to 98%, this gearbox is ideal for applications where minimizing energy loss is critical. It ensures optimal power transmission and reduces heat generation — making it suitable for continuous-duty cycles in energy-conscious operations and high-torque environments.

Optimized Gear Ratio (3.38:1): The 3.38:1 ratio delivers balanced speed reduction and torque amplification. This makes the gearbox suitable for conveyors, robotics, packaging machines, and materials handling systems, where precise motion control is essential.

Single-Stage Helical Gear Design: The single-stage configuration offers reduced mechanical complexity and high reliability. Its design reduces backlash and vibration, enabling smoother motion in synchronized multi-axis systems such as CNC machinery or assembly stations.

Aluminium Housing for Thermal and Weight Benefits: The gearbox housing is constructed from aluminium — providing excellent thermal conductivity and corrosion resistance while significantly reducing total system weight. Ideal for mobile equipment, food processing machinery, and applications where ease of installation and environmental resistance are priorities.

Input Shaft Diameter – 14 mm: A robust 14 mm input shaft facilitates mechanical integration with standard IEC motor frames and pulleys. This ensures torque stability and simplifies coupling in drive assemblies in fan systems, pumps, and automated manufacturing lines.

Output Shaft Diameter – 14 mm: The 14 mm keyed output shaft is precision-machined for a secure power transfer to driven components. Suitable for direct shaft connections or sprocket mounting in compact transmission systems such as sorting equipment, printing technology, and compact gear trains.

IEC Motor Interface – 71B14: Designed with an IEC 71B14 motor flange interface, allowing for quick and standardized motor coupling. This modularity is excellent for OEM applications where frequent motor swaps or system retrofitting is required without custom adapters.

Gear Size 211A – Compact and Modular Form Factor: The 211A size format enables integration in both vertical and horizontal orientations — perfect for tight installations in automated lines, lift systems, and panel-mounted machinery.

Durable and Maintenance-Friendly Construction: Its sealed-for-life lubrication and rigid casting allow for reduced maintenance intervals and extended operational lifespan, especially under moderate-to-heavy industrial workloads.

Ideal for Industrial Automation and Machinery: The gearbox's mechanical characteristics support a wide range of use cases including but not limited to automation cells, palletizing systems, decentralized drive systems, packaging lines, and light-duty lifting mechanisms.
