I. Main Features
1. Material & Structural Properties
- Carbon Fiber/Glass Fiber Composite: Aerospace-grade fiber-reinforced polymer reduces weight by 60% compared to steel couplings while delivering high specific strength/stiffness and low rotational inertia.
- Flat Disc Pack Design: Optimized for transmitting high torsional vibration torques and radial forces, especially suited for high-speed applications (e.g., gensets) with speeds exceeding 10,000 rpm.
- Electrical Insulation & Non-Magnetic: Prevents stray currents from damaging bearings (e.g., shaft currents in generators) and ideal for EMI-sensitive environments.


2. Mechanical & Dynamic Performance
- Low Reaction Forces & Linear Response: Near-linear disc deformation reduces bearing loads by up to 40%, extending drivetrain lifespan.
- High Misalignment Compensation: Single disc pack compensates angular/axial shifts; dual-disc configuration adds radial tolerance for installation errors/thermal expansion.
- Shock Absorption & Vibration Damping: High damping suppresses torsional vibrations; acoustically optimized models reduce noise for residential-area compliance.
3. Environmental Resilience
- Maintenance-Free Operation: No lubrication required; corrosion-resistant in extreme temperatures (-45°C to 100°C), marine, and oil/gas environments.
- High Protection Rating: Standard IP65 (dust/water jet resistant); optional explosion-proof certification (ExiaⅡCT6) for hazardous areas.
4. Installation Advantages
- Modular Design: Customizable dimensions (up to 3.5m diameter) and interfaces for complex spaces.
- Lightweight Construction: Simplifies hoisting and reduces installation costs.
