High Speed / High Torque Servo Couplings


Zero-Max's ServoClass Couplings feature fail safe clamping hubs that provide maximum torque transmission in high speed applications. The ServoClass Couplings are designed to provide superior shaft engagement in servo motor applications at speeds up to 10,000 rpm without the use of keyways.

ServoClass design features include precise 304 stainless steel disc members. These are aligned and locked precisely into position onto the high strength aluminum alloy hubs with ISO 4762 XL 12.9 corrosion resistant socket head cap screws. The coupling assembly process itself is controlled with a computerized torque control system for the most precise fit of all components.

Zero-Max ServoClass couplings designed to meet the precise positioning requirements and high speed reversing loads common in many servo motor systems found in automation applications, packaging systems, semi-conductor assembly, laboratory automation, medical equipment, and more.

The couplings are available in 12 sizes with both single and double disc models and can handle torque ratings ranging from 0.5 to 250 Nm. ServoClass couplings can also accommodate parallel (radial), axial, and angular misalignments. All ServoClass Couplings are manufactured of RoHS compliant materials.
