Compact Composite Disc (CD) shaft couplings capable of withstanding the most demanding servomotor systems have been launched by Zero-Max. Precision machined in ASTM A 108 steel and 6061-T6 aluminium, the body components of the couplings are inherently balanced, while the functioning components are made from a precisely oriented and layered composite material similar to those composites used in aerospace applications. To ensure precise alignment of the assembled components, ISO Class 12.9 hardened shoulder bolts are used.
Features include high dynamic load capacity and high torsional stiffness to ensure reliable system operation, zero backlash, and they provide smooth operation at high speeds.
Standard models and sizes include single and double flex models with clamp style hubs with or without keyways. The torque capacities range from 40Nm to 1436Nm and beyond, with speed ratings from 4400rpm to 17,000rpm.
