ServoClass couplings handle high-speed reversing loads and deliver precise positioning in demanding medical and laboratory servomotor applications. ServoClass couplings handle high-speed reversing loads and deliver precise positioning in demanding medical and laboratory servomotor applications. Manufactured of RoHS-compliant materials, the couplings feature 304-stainless-steel disc packs and 7075-T6 aluminum hubs and center members. All models have clamp-style hubs with corrosion-resistant socket-head cap screws. This design provides zero backlash and high torsional stiffness to avoid system resonance. Standard couplings perform at speeds to 10,000 rpm. The product line includes eight sizes with torque ratings to 530 lb-in., in both inch and metric bores.
