Product Description


Adjustable Speed Drive consists of a rugged, sealed cast case, an input shaft, output shaft and adjustable speed control. Speed of the output shaft is regulated precisely and easily through a control lever which includes a convenient locking mechanism or a screw control to hold speed at a desired speed setting. Adjustable speed drive models are available with output in clockwise or counter-clockwise rotation to meet individual speed control requirements. Two models are equipped with a reversing lever that permits clockwise, neutral and counter-clockwise operation. The general principle of operation of Adjustable Speed Drives gives infinitely variable and adjustable speed by changing the distance that four or more one-way clutches rotate the output shaft when they move back and forth successively.

Adjustable Speed Drive

Zero-Max actually began when inventor Sterling Stageberg designed a mechanical adjustable speed transmission drive used on automotive windshield wipers. His design allowed a variable drive output speed from a constant input from zero to maximum (thus, Zero-Max). Zero-Max has been involved with the design of adjustable speed drives for over half a century, and is the leading manufacturer of adjustable speed drives today.
