Zero Max

It all began in 1949, when Minnesota inventor Sterling Stageberg designed a unique mechanical variable speed transmission drive. Stageberg's design varied the output speed from a constant input from zero to maximum. Initially, it was used on automotive windshield wipers and became an instant success. The product filled an important industry need at the time, which helped launch the company. It also provided the idea for the Zero-Max brand, a name carried on all of today's Zero-Max products sold throughout the world.

Flexible Shaft Couplings

Shaft misalignment can limit the performance of machines, cause excessive wear, and often lead to premature failure. Flexible shaft couplings can help prevent these issues by transmitting torque while also accommodating for parallel, axial, and angular misalignment between drive components. High performance flexible shaft couplings can also reduce vibration, dampen noise, and protect drive shaft components from overload.

• Composite Disc Couplings

Our Composite Disc shaft couplings (CD® Couplings) deliver high performance with zero backlash, and are designed to withstand the rigors of the most demanding servomotor systems. We manufacture the functional parts of our composite disc shaft couplings from precision-oriented, aerospace-grade, layered composite materials. Available options include single-flex, double-flex, and floating shaft couplings with either set screw type, bushing type, or clamp type hubs,

• ServoClass® Shaft Couplings

The ServoClass shaft coupling provides the optimal blend of performance, durability, and price. These flexible shaft couplers are manufactured from high-quality materials using state-of-the-art CNC manufacturing equipment, allowing Zero-Max to offer high performance, flexible shaft couplings at highly competitive prices.

• Control-Flex Shaft Couplings

Control-Flex shaft couplings are specially designed and manufactured for use with feedback devices such as tachometers and encoders. These flexible shaft couplings are engineered for zero backlash operation to ensure accuracy. Additional features include clamp hubs for superior,

• Schmidt Couplings

Zero-Max's Schmidt shaft couplings are uniquely designed to handle applications with challenging or extreme misalignments. Our line of shaft couplings includes models for large shaft offsets and inline shaft applications. Zero-Max offers a variety of Schmidt coupling designs:

a. Schmidt Offset Shaft Couplings

b. Schmidt Inline Couplings

c. Schmidt 5-D Couplings

d. Schmidt Flexible Couplings
