Couplings

Zero-Max offers Couplings. These are used for servomotor applications. Couplings with aluminium hubs have low weight and low inertia making them an excellent choice for servomotor and other precision motion control applications. They provide the ideal combination of high torsional stiffness and high dynamic load capacity to ensure reliable machine operation. Designers today are using more servomotors to improve machine speed and accuracy. As speeds increase, so does stress on mechanical components. These are designed so that the working part is made of a composite material. It withstands the punishment and stress of a servomotor - everything a servomotor can dish out. In comparison, bellows style couplings have high torsional stiffness specifications but are too brittle to withstand the punishment of high speed reversing applications. Beam style couplings also have limitations because they have relatively low torsional stiffness that will limit speed and machine accuracy. They address the many challenges of the latest servo motor designs providing precision positioning under high reverse loads and with reliable 24/7 operation. Aluminium hub CD Single Flex models are available in clamp style hubs with or without keyways. The torque capacities range from 40 Nm to 1436 Nm and beyond with speed ratings from 4400 RPM to 17,000 RPM. All CD couplings are environmentally friendly and are manufactured of RoHS compliant materials.
