Then we recommend the explosion-proof helical-bevel gear units in equipment category II2GD. These right-angle gear units have torques from 200 Nm to 50,000 Nm and feature a particularly compact design.

With their high efficiency in both directions of torque and at any input speed, they are also very energy-efficient. Their high-endurance gearing is wear-free and lasts a gear unit’s lifetime. For precise positioning tasks, you can use the K series explosion-proof gear units with reduced backlash.

A long, maintenance-free service life enhances this economy and efficiency. That’s why the K series is used in so many applications in potentially explosive atmospheres.
