ServoClass® Couplings provide high torsional stiffness, zero backlash and low hysteresis to ensure repeatable, precise positioning at speeds up to 10,000 RPM. Designed with 304 stainless steel disc packs and 7075-T6 aluminum hubs, the units are durable and balanced. 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 product is ideal for all types of automation and packaging assembly, including most systems using ball screws and servo motors. Units are available in single and double flex models in inch and metric bore sizes from 0.157" (4mm) to 1.75" (45mm). All models and sizes feature clamp style hubs and operate in temperatures from -22° to 212°F (-30° to 100°C).
