Zero-Max ServoClass couplings

Zero-Max ServoClass couplings now feature improved clamp-style hub design for handling larger shafts and higher torque.

The couplings are designed for high-speed reversing loads and precise positioning requirements in demanding servomotor applications at speeds up to 10,000 rpm. The clamp-style hubs provide superior shaft engagement for these high-speed applications. The increased clamping strength eliminates the need for keyways while providing a clean, balanced design.

Available in 12 sizes in single and double-disc models, the couplings handle torque ratings ranging from 0.5 to 250 Nm. Manufactured of RoHS-compliant materials, the couplings with improved clamp style hubs are designed with 304 stainless steel disc members. To ensure precise alignment of the assembled components, ISO 4762 CL 12.9 corrosion-resistant socket head cap screws are used with a carefully controlled assembly process.

The couplings are suitable for precision positioning requirements and the high reverse load characteristics of AC and DC servo motor systems using ball screws. Applications include automation of all types, packaging, semiconductor assembly, laboratory automation and medical equipment.
