Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Shock and Vibration Absorption: Designed to buffer mechanical shocks and dampen vibrations in rotating or linear motion systems, ensuring smooth operation.
  • Misalignment Compensation: Facilitates angular, parallel, and axial misalignment in coupled machinery, enhancing durability and performance.

Key features

  • 1. Material Technology

    • With a corrosion-resistant Silicon Carbide (SIC) and high-strength plastic composite material, ensure durability in harsh industrial environments. This combination outperforms traditional all-metal or rubber-based buffers in resisting wear and chemical exposure*.

  • 2. Interactive Design

    • With a modular snap-fit design, simplify installation and maintenance compared to rigid, multi-part couplings. Adjust or replace components quickly without specialized tools*.

  • 3. Performance Parameters

    • With a vibration-damping efficiency of up to 90%, handle high-impact loads more effectively than standard elastomer buffers. Tested to support continuous operation at temperatures up to 200°C*.

  • 4. Scenario Solutions

    • Designed for industrial machinery and commercial equipment, this buffer reduces alignment errors and shock transmission in heavy-duty applications, unlike consumer-grade alternatives*.

  • 5. Certification Standards

    • Complies with ISO 3502-1 industrial coupling safety standards, ensuring reliability in critical machinery systems. Meets international specifications for chemical resistance and thermal stability*.
