Three sizes in both single and double flex models have been added to the Zero-Max ServoClass coupling line. Providing even higher torsional stiffness than previous models, these couplings are designed to handle high speed reversing loads and precise positioning requirements in today’s demanding servomotor applications. The new sizes handle bore diameters from 0.875 to 1.378 in. and operating torque from 3,937 to 9,843 in. lbs. Manufactured of RoHS compliant materials, these couplings are lightweight and designed with 304 stainless steel disc packs and 7075-T6 aluminum hubs and center members.
