Designed with 304 stainless steel disc packs and 7075-T6 aluminum hubs, Zero-Max ServoClass couplings provide high torsional stiffness, zero backlash and low hysteresis for precise positioning at speeds up to 10,000rpm. To ensure precise alignment of the assembled components, ISO 4762 CL12.9 corrosion-resistant socket head cap screws are utilized with a carefully controlled assembly process. The couplings are available in single- and double-flex models in inch and metric bore sizes from 0.157 in. (4mm) to 1.750 in. (45mm). All models and sizes feature clamp-style hubs and operate in temperatures from a low of -22°F to a high of 212°F.
