Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Torque Transmission & Misalignment Tolerance: Designed to transmit rotational power between shafts while accommodating angular, parallel, and axial misalignment, ensuring smooth operation in dynamic systems.
  • Shock Absorption & Vibration Damping: Combines durable steel structural components with flexible rubber elements to absorb shocks and reduce vibration, protecting connected machinery.

Key features

  • 1. Corrosion-Resistant Material Technology

    • With corrosion-resistant blackened 45# steel and high-tensile elastic rubber, ensure durable, long-lasting performance in harsh industrial environments. The blackened surface treatment provides 50% better corrosion resistance than uncoated steel couplings*, making it ideal for wet or chemically exposed settings.

  • 2. Versatile Plum-Jaw Spider Design

    • The plum-jaw spider structure enables up to 5° angular misalignment tolerance, outperforming rigid couplings by 40% in flexibility*. This design allows seamless adaptation to misaligned shafts while maintaining smooth rotational motion, reducing wear and downtime in machinery.

  • 3. High-Torque Performance Capacity

    • Delivers a maximum torque capacity of 600 Nm, 25% higher than conventional rubber couplings*, ensuring reliable power transfer in heavy-duty applications. The elastic rubber core absorbs shocks, protecting connected equipment from sudden load impacts.

  • 4. Industrial-Grade Scenario Solutions

    • Optimized for continuous operation in industrial machinery, reducing vibration transmission by 40% compared to rigid couplings*. Its flower-shaped coupling design and flexible jaw mechanism make it ideal for high-demand manufacturing, automotive, and automation systems requiring precise motion control.

  • 5. Compliance with Global Standards

    • Constructed to meet ISO 9001 quality standards and RoHS compliance, ensuring safety and reliability in global mechanical systems. The rubber components are engineered for eco-friendly disposal, aligning with modern sustainability requirements.
