Zero-Max Double Flex A1C high-performance CD couplings

Zero-Max’s Double Flex A1C high-performance CD couplings provide higher misalignment capacity than the Single Flex model. They have wider shaft spacing and improved clamping system, making them suitable for demanding servo motor and motion control applications.

The coupling provides precise positioning under high-speed reversing loads without fatigue for reliable 24/7 operation. The CD coupling design has high torsional stiffness, yet allows for misalignment in high-stress applications. In addition, the zero-backlash couplings work well with reversing loads and provide smooth operation at high speeds. The design is compact to allow for a smaller assembly.

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

All CD A1C components are made of premium materials. Precision-machined hubs are made from ISO grade 7075-T6 aluminium; hubs are black anodised to a MIL-A-8625 Type 2, Class 2 finish; and 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. The material is said to have excellent chemical and moisture resistance.

The A1C couplings are precise, robust and available in six sizes. Peak torque capacities range from 40 to 564 Nm with speed ratings from 6700 to 15,000 rpm depending on the model.
