The Pre-stage worm gear boxes from the CMP series consist of a worm speed reducer and an AC motor, with pre-stage between them with a unique gear ratio of i=3. Some characteristics of the pre-stage include ground gears with low noise level, compact design, and lifelong lubrication. The pre-stage has a single output bearing and therefore, it can only be used between the motor and the gearbox.
