Zero-Max ServoClass® couplings now feature improved clamp style hub design for handling larger shafts and higher torque. ServoClass couplings are designed for high speed reversing loads and precise positioning requirements in today’s demanding servomotor applications at speeds up to 10,000 rpm. The new 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, ServoClass couplings handle torque ratings ranging from 0.5 to 250 Nm. Manufactured of RoHS compliant materials, ServoClass 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 utilized with a carefully controlled assembly process.             

Zero-Max ServoClass couplings are ideal for precision positioning requirements and high reverse load characteristics of AC and DC servo motor systems using ball screws. These include automation of all types, packaging, semi-conductor assembly, laboratory automation and medical equipment.
