Modular Worm Gearbox: Industrial Flexibility and Power

The modular worm gearbox represents the most versatile solution for mechanical power transmission. Engineered for interchangeability, these gearboxes allow for the rapid mounting of flanges, feet, and torque arms, perfectly adapting to any plant configuration and installation requirement.

Technical Specifications and Performance Range

Our line of worm gearboxes is structured to cover every need, from light-duty to the most demanding industrial applications:

  • Wide Range: 12 available sizes for total torque coverage.

  • High Power: Capability to handle a maximum applicable power of up to 55 kW.

  • Maximum Torque: Smooth transmission up to 3000 Nm.

  • Reduction Ratios: Available up to 100/1 for precise speed control.

  • Universal Mounting: Designed to offer a wide range of mounting positions in space.

Materials and Construction Innovation

The manufacturing quality of every worm gearbox is guaranteed by the choice of specific materials for each size:

  1. Aluminum Body (up to size 80): Made of die-cast aluminum, designed to combine extreme lightness, structural strength, and torsional rigidity.

  2. Cast Iron Body (larger sizes): An ultra-robust structure designed to withstand the most severe stresses and heavy industrial environments.

  3. Silent Technology: The adoption of “ZI” profiles on screws and gears ensures fluid operation, extremely quiet performance, and a total absence of vibration, extending the service life of all components.

Why Choose a Modular Worm Gearbox?

Choosing modularity means optimizing maintenance times and reducing inventory costs. Whether for conveyor belts, mixers, or lifting systems, our worm gearbox offers:

  • Certified Reliability: Every unit is tested to ensure consistent performance.

  • Adaptability: Easy integration thanks to a wide range of accessories (flanges and torque arms).
