High Gear Efficiency – 98% efficiency guarantees minimal energy loss, making this gearbox ideal for energy-sensitive applications such as automated manufacturing lines and conveyor systems.

Single-Stage Configuration – The 1-stage helical design ensures fewer moving parts, reducing wear and enabling highly reliable operation in high-duty cycle environments.

Precision Gear Ratio (2.05:1) – The exact transmission ratio allows for fine motor speed adjustment, which is critical in dosing systems, mixers, and robotic actuators requiring precision movement.

Robust Aluminium Housing – The corrosion-resistant aluminium casing provides strength without unnecessary weight. Excellent for mobile machinery and food processing environments where hygiene and weight reduction are critical.

Compact Size (211A) – The space-saving configuration simplifies integration into machine assemblies with limited footprint, such as packing machines and compact automated systems.

Input Shaft – With an 11 mm input shaft, the gearbox is compatible with standardized IEC motor flanges, allowing fast and modular installation across a wide range of servo and asynchronous motors.

Output Shaft – 14 mm precision-machined output shaft ensures stable torque transmission and easy coupling to driven components such as pumps, rollers, and linear actuators.

Gear Motor Interface – IEC B14 input (63B14) and B14 output flange (71B14) conform to standard mounting dimensions, facilitating seamless motor integration in both retrofit and OEM designs.

Hydro-Mec Modularity – Universal interface and interchangeable components make this gearbox easy to pair with a broad array of gear motors and automation systems with minimal customization.

Designed for Industrial Automation – Optimized for demanding use cases in conveyors, picking systems, food machinery, and light-duty materials handling equipment.

High Torque at Low Speeds – Due to its helical gearing and low ratio, the gearbox delivers substantial torque boost while maintaining low output shaft RPM, suitable for extruders and winding systems.

Low Noise Operation – Precision helical gears reduce vibration and noise, enabling use in noise-sensitive environments such as medical device manufacturing and cleanroom production.

Maintenance-Friendly – Lubricated for life and built with minimal moving components, this gearbox reduces required downtime and increases machine uptime.

Lightweight Construction – Only aluminium materials used, making this unit easy to handle and suitable for overhead mounting or mobile machinery.

Environmental Tolerance – The sealed aluminium housing provides excellent resistance to moisture, dust, and moderate chemical exposure—ideal for agricultural and light chemical processing environments.
This makes the Hydromec 211A an outstanding choice when reliability, efficiency, and integration flexibility are required across industrial automation, packaging, food processing, and light mechanical engineering systems.
