i=7.5:1 MI30C with motor flange

Classic worm gears


Worm gears are cost-effective and generate high torques in a small space. However, their efficiency is lower than other gearboxes, which leads to energy losses in the form of heat. However, this enables a high level of self-locking in the gearbox, which means that any torque generated by the application, which acts back on the worm shaft, is braked or blocked by the gearbox. They are used when high torques are to be generated through high reductions and/or self-locking is required.


  • Inexpensive
  • Self-locking 
  • Robust, durable
  • High reduction up to 100:1 in one step
  • Flexible connection through implemented input shaft

Application example 

  • Cable winches, crane drives, sliding gates
  • Elevators 
  • Conveyor belts, assembly lines 
  • Fans, pumps 
  • Screw conveyors, extruders 
  • Agitators, kneading machines
