Supplier's note

  1. Technical Breakthroughs:

    • Material Blend: The PU-rubber composite reduces wear by 40% compared to traditional rubber couplings.
    • Spider/Jaw Design: Achieves 25% better torsional stiffness than industry benchmarks.
    • Precision Molding: Tolerances within ±0.1 mm ensure seamless shaft alignment.

  2. Version Selection Guide:

    • Base Model: Ideal for standard industrial applications (e.g., HVAC systems) requiring up to 100 Nm torque.
    • Advanced Model: Suitable for food processing or light chemical machinery needing oil resistance and wider temperature adaptability.
    • Pro Model: Engineered for heavy-duty robotics or mining equipment with extreme torque demands and misalignment (e.g., 5 mm tolerance enables use in uneven terrain).

With the Pro Model’s 5 mm misalignment tolerance, you can stabilize heavy machinery in uneven environments. The Advanced Model’s +20% chemical resistance ensures longevity in lubricated systems. Choose the Base Model for cost-effective solutions in controlled settings.
