Worm Gearboxes

Gearboxes orthogonal worm gear, silent and compact solutions for high reduction

The orthogonal worm gear reducers represent a compact, silent, and highly efficient solution for power transmission in the industrial sector. 

Thanks to the combination of worm gear and helical wheel, they allow for high reduction ratios in compact spaces, ensuring smooth and reliable operation.
Manufactured with high-quality and precision materials, they offer high reliability even under demanding conditions, reduced maintenance costs, and excellent operational efficiency.

Available in various modular configurations, they are versatile to install and suitable for numerous sectors: handling, packaging, automation, food processing, and much more. 

The reducers can be prepared for combined flange mountings to achieve even higher ratios.
