Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Torque Transmission & Motion Connection: Designed to transmit high torque and rotational motion between rotating shafts, ensuring efficient power transfer in machinery.
  • Misalignment Tolerance: Rigid and flexible structural options accommodate slight shaft misalignment, reducing wear and protecting connected components.

Key features

  • 1. Material Technology

    • With a corrosion-resistant steel and stainless steel body, ensure durability in harsh industrial environments. The yellow polymer casing provides enhanced insulation and protection, outperforming basic metal-only couplings*.

  • 2. Interactive Design

    • With a universal roller chain structure, achieve secure torque transmission and easy installation, offering greater flexibility than traditional rigid couplings*. The interlocking teeth design allows smooth motion transfer even in misaligned setups.

  • 3. Performance Parameters

    • With high torque capacity and misalignment tolerance, handle heavy-duty machinery demands more effectively than standard rigid couplings*. The rigid-flexible hybrid design balances strength and adaptability for varied operational conditions.

  • 4. Scenario Solutions

    • With customizable sizes and material options, adapt to diverse industrial applications, from manufacturing to heavy equipment, surpassing non-modular alternatives*. The robust build ensures reliability in continuous operation for commercial use.

  • 5. Certification Standards

    • With RoHS certification, meet stringent environmental and safety regulations, ensuring compliance and sustainability compared to non-certified couplings*.
