Stronach ™ Helical Gearbox

Type: Strong Series

Also called Stronach™ Strong helical gearboxes, are designed with an easy-to-clean solid-cast and robust cast iron housing that is machined in one fixing. This ensures maximum torque transmission with high precision of the gears. All bearings are designed for optimum lifetime and safe operation. Oil sealing ring are standard made of nitrile rubber.

Stronach™ Strong helical gearboxes are supplied as 2- or 3-step models. The Stronach™ helical gearboxes are made with an output torque of up to 2,400 Nm and with gear ratios from approx. 2:1 to 80:1 depending on the gear size. The helical gearboxes can be supplied with a motor flange and coupling for direct mounting of an AC/DC motor or any special motor you wish, or with free input and output shaft. Furthermore, the Stronach™ helical gearboxes can be supplied as a foot or flange gearbox.
The gearboxes can be manufactured according to customer requirements, for instance with stainless steel output shaft or other adaptations.
