SN Series Helical Gearboxes
SN series helical gearboxes are mostly intended for small conveyor belts and other similar machines. These gearboxes consist of two helical gears. The shell is made of aluminum, and the gears can be made of either steel or cast iron.
Such gearboxes are only produced at fixed ratios. To change the ratio, input pulley size can be changed, which changes the gearbox’s output.
