With higher efficiency than pure worm gear units, the Sew Eurodrive explosion-proof helical-worm gear units are particularly powerful. The II2GD version can be used reliably in many explosion-proof applications.
Particularly powerful: with impressive efficiency, even in potentially explosive atmospheres
The simple design of these gear units ensures cost-effectiveness. The individual adjustment of torque and speed allows for space-saving installation of our helical-worm gear units. Use the S series gear units to implement simple tasks in your machine or plant applications.
The combination with a helical gear stage significantly increases the efficiency compared to pure helical-worm gear units. The linear power transmission makes the worm gear units especially quiet in operation. Why? The force is transferred to the input shaft by the worm shaft and the worm gear, which dampens torque impulses and allows for a lower noise level. The torque ranges from 92 Nm to 4000 Nm.
