Zero-Max ServoClass Model 55 couplings

The ServoClass coupling Model 55 from Zero-Max is available in both single- and double-flex models. Providing high torsional stiffness with low inertia, the ServoClass couplings are designed to handle high-speed reversing loads and precise positioning requirements in demanding servomotor applications.

The Model 55 in single- and double-disc models handles bore diameters from 10 to 30 mm. They are lightweight and are designed with 304 stainless steel disc packs and high-strength aluminium hubs and centre members. All models and sizes feature clamp-style hubs with corrosion-resistant socket head cap screws. All materials are RoHS compliant.

Claimed to be a better choice than bellows and beam-style couplings, the ServoClass couplings perform in 24/7 servomotor applications. When the application cycle becomes faster they are said to outperform beam couplings, which are subject to wind up, and bellows couplings, which have a fragile design.

Fourteen sizes of standard off-the-shelf ServoClass couplings are now available in both inch and metric sizes. The couplings are suitable for applications in automation, packaging, semiconductor assembly and laboratory automation, as well as for most products that use ball screws and servomotors.
