Zero-Max has added three new sizes to its ServoClass coupling line designed to handle high-speed reversing loads and precise positioning requirements. According to the company’s press release, the new sizes handle bore diameters from 0.875 in. (20 mm) to 1.378 in. (35 mm) and operating torque from 3,937 to 9,843 in. lbs. (100 to 250 Nm). These couplings are lightweight, designed with 304 stainless steel disc packs and 7075-T6 aluminum hubs and center members. The couplings feature clamp-style hubs with corrosion-resistant, socket-head cap screws.
“ServoClass couplings have an elegant, yet very robust design that performs reliably in 24/7 servomotor applications,” says Robert Mainz, sales manager at Zero-Max. “When the application cycle becomes faster, they outperform beam couplings, which are subject to wind up, and bellows couplings, which have a fragile design.”
Eleven standard sizes are available for clean room applications in automation, packaging, semi-conductor assembly, laboratory automation, medical equipment and products that use ball screws and servomotors.
