Zero-Max CD A1C motor shaft couplings

Featuring high torsional stiffness and high dynamic load capacity, Zero-Max CD A1C couplings are designed to ensure reliable machine operation. They provide precise positioning under high-speed reversing loads without fatigue. In addition, these zero-backlash couplings are suitable for reversing loads and provide smooth operation at high speeds. The design is compact to allow for a smaller assembly - enabling a smaller machine footprint.

Designed with improved clamp-style hubs for handling larger shafts and higher torque, the design provides good shaft engagement. Shafts have increased clamping strength, eliminating the need for keyways for a cleaner, better-balanced design.

All components are made of premium materials. Machined hubs are made from ISO grade 7075-T6 aluminium and hubs are black anodised to MIL-A-8625 Type 2, Class 2 finish. Recessed fasteners are ISO 4762 grade 12.9 socket head cap screws.

The composite disc is made of high-precision composite material that is manufactured to strict aerospace and Six Sigma practices. This material has good chemical and moisture resistance. All components are tested with finite element analysis (FEA) software for perfect balance. All materials used are ecofriendly with no banned substances according to RoHS directives.

The couplings are available in six sizes. Torque capacities range from 40 to 564 Nm with speed ratings from 6700 to 15,000 rpm depending on model.
