High, reliable and tested performance (Ni bronze); optimization of worm gear pair performances (ZI involute profile and adequately conjugate worm wheel profile)
Compactness, standardized dimensions and compliance with standards
Rigid and precise cast iron monolithic casing
Generous internal space between train of gears and casing allowing high oil capacity, lower oil pollution, greater duration of worm wheel and worm bearings, and lower running temperature
Possibility of fitting particularly powerful motors and transmitting high nominal and maximum torques
High manufacturing quality standard
Possibility of obtaining multiple drives and at synchronous speed
