Such types of  Slew drive are perfect for applications that require both load holding and rotational torque from the same gear box. The drives come with an hourglass worm technology, which increase the efficiency of the drives. The difference between normal and hourglass technology is that, in a conventional worm gearing system, only one tooth of the gear is in contact with the worm shaft, whereas in our systems, it can go up to 6 gears in contact.
