ServoClass® Couplings from Zero-Max reduce heat transfer from servo motors to driven shafts, reducing heat transfer and variations in system accuracy caused by thermal expansion. It features stainless steel discs designed into the center of the coupling that dissipate heat generated from a connected servo motor.
These couplings also provide high torsional stiffness, zero backlash and low hysteresis, further ensuring repeatable precise positioning.
“Thermal transfer is a growing concern in servo motor system design,” reports Robert Mainz, Zero-Max sales manager. “As cycles become faster and heat increases, especially in tightly enclosed designs, these couplings minimizes heat transfer through the shaft components.”
Three new sizes have been added to the line. They handle bore diameters from 0.875 in. (20 mm) to 1.378 in. (35 mm) and operating torque from 885 to 2213 in. lb (100 to 250 Nm). Many additional sizes are available starting with the smallest bore size 0.157 in. (4 mm) and larger.
All ServoClass couplings are manufactured of RoHS compliant materials. They are lightweight and are designed with 304 stainless steel disc packs and 7075-T6 aluminum hubs and center members. They are available in single and double flex models in inch and metric sizes. All models and sizes feature clamp style hubs with corrosion resistant socket head cap screws.
