Supplier's note

  1. Technical Breakthroughs:

    • Spider Structure: Reduces stress concentration by 25% compared to rigid couplings.
    • Radial Grooves: Achieves 30% faster heat dissipation than smooth-surface designs.
    • Composite Material: 20% lighter than aluminum equivalents while maintaining torsional stiffness.

  2. Version Selection Guide:

    • Base Model: Best for standard industrial applications (e.g., conveyor systems) where cost-efficiency is prioritized.
    • Advanced Model: Suited for robotics and automation requiring higher misalignment tolerance (e.g., robotic arms with frequent angular shifts).
    • Pro Model: Ideal for extreme environments (e.g., high-temperature foundries or chemical plants) where durability and precision are critical.

With the Pro Model’s 2.5° misalignment tolerance, you can ensure stable operation in uneven machinery setups. Pair its carbon-blend material with the Advanced Model’s extended temperature range to handle harsh industrial conditions without compromising performance.

Note: Specifications are illustrative and may vary based on configuration.
