Zero-Max is a mechanical adjustable speed drive. Five sizes provide constant torque of 12 to 200 inch pounds throughout the speed range. The speed range is infinitely adjustable from 0 to 1/4 of the input speed under full rated load. This is generally stated as 0-400 RPM under full rated load assuming an input of 1800 RPM.
For lower speed/higher torque applications, some Zero-Max Drives are available with in-line or right angle gearheads. Some Zero-Max Drives may be purchased with standard electric motors or they may be connected to any rotating power source up to 2000 RPM. Speed adjustments are easily made by moving a lever control through an arc or turning the handwheel of a screw type control. In either case, precise speed control settings are possible.
Over 1 million Zero-Max Drives have been put to work in a wide variety of applications. They are available from distributors in all major markets throughout the world.
