Areas of application

The E series gearboxes are ideal for a wide range of industrial applications requiring high reduction ratios in a compact size:

Conveying machines - Belt conveyors, roller conveyors, material handling systems
Lifting equipment - Lightweight hoists, winches, small capacity overhead cranes
Agricultural machinery - Irrigation equipment, harvesting machines, feeding systems
Food industry - Mixers, blenders, packaging machines
Industrial automation - Robots, positioners, turntables
Doors and gates - Automatic opening systems, industrial doors

Competitive advantages

Compactness and versatility

The perpendicular shaft configuration allows integration into confined spaces, while the multiple mounting options offer exceptional installation flexibility to suit all mechanical configurations.

High reduction ratio

Thanks to worm gear technology, the E series offers significant reduction ratios in a single stage, enabling very low output speeds without the need for complex and bulky multi-stage reducers.

Natural self-locking

The specific geometry of the worm gear provides a natural self-locking effect at certain ratios, eliminating the need for external braking systems in many applications and improving operational safety.
