Worm gearboxes R-series and torque limiters

The new worm gearboxes were improved by adding three innovative principles: two are technical and one is commercial.

• All aluminium components are die casted (from size 28 to size 70) to increase resistance to torsional and structure flexibility
• ZI teething profile (section and involute) has been adopted to increase efficiency and silentness
• Finally, a modular attachable output flange (FL) has been adopted to increase flexibility

New ideas to approach a bigger market together: first, since 1987, with the patent of the torque limiter built inside our standard gearbox.
