Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Torque Transmission & Shaft Connection: Designed to connect rotating shafts in machinery, efficiently transmitting torque while accommodating misalignment between connected components.
  • Vibration Damping & Misalignment Tolerance: The flexible elastomeric inner ring absorbs shocks and vibrations, while the split design and splined outer rings ensure stable operation even under angular, axial, or radial misalignment.

Key features

  • 1. Material Technology

    • With corrosion-resistant steel and vibration-damping rubber, ensure durability and shock absorption in demanding environments. The blackened steel surface enhances resistance to wear and rust, outperforming standard uncoated couplings*.

  • 2. Interactive Design

    • With a split design and splined outer rings, you can easily install/remove the coupling without disassembling shafts, saving up to 50% installation time compared to rigid couplings*. The universal/gear structure allows precise torque transmission.

  • 3. Performance Parameters

    • With a flexible elastomeric core and steel reinforcement, handle up to 4° angular misalignment and absorb 30% more vibration than rigid couplings*. This ensures stable operation in high-torque applications like pumps and motors.

  • 4. Scenario Solutions

    • Designed for drum-type motors and pumps, you can ensure seamless operation in industrial settings with frequent misalignment or vibration. Customizable sizes/materials meet specific needs, unlike one-size-fits-all solutions*.

  • 5. Certification Standards

    • With RoHS compliance, you can meet strict environmental and safety regulations, making it ideal for global industrial applications. This certification ensures no hazardous substances in materials*.
