A new ServoClass Coupling size in both single and double flex models has been added to the Zero-Max ServoClass coupling line. Providing high torsional stiffness, these ServoClass couplings are designed to handle high speed reversing loads and precise positioning requirements in today’s demanding servomotor applications.

The new size in single and double disc models handles bore diameters from .375 in. (10 mm) to 1.125 in. (30 mm). These new ServoClass couplings are lightweight and are designed with 304 stainless steel disc packs and high strength aluminum hubs and center members. All models and sizes feature clamp style hubs with corrosion resistant socket head cap screws. All materials are RoHS compliant.

ServoClass couplings feature zero-backlash, have an elegant, yet robust design, require no maintenance and are quick and easy to install.

Zero-Max ServoClass couplings are a better choice over beam or bellow style couplings. They have a sleek, elegant and robust design that performs reliably in 24/7 servomotor applications. They reduce shock loads and prevent positioning errors. When the application cycle becomes faster, they outperform beam couplings, which are subject to wind up, and bellows couplings, which have a fragile design. 

A total of nineteen sizes of standard off-the-shelf ServoClass couplings are now available in both inch and metric sizes. These couplings are ideal for clean room applications in automation, packaging, semi-conductor assembly, laboratory automation, medical equipment and for most products that use ball screws and servomotors.
