GUMMI BR-Series Swivel Elastic Rubber Couplings

GUMMI BR-Series Swivel Elastic Rubber Couplings

Vibration Absorption & Maintenance-Free Operation for Extended Equipment Life
The GUMMI BR-Series Elastic Couplings are specially designed for low-rotation applications, offering a compact design comparable to rigid and semi-rigid couplings while maintaining exceptional flexibility in absorbing misalignments, vibrations, and torque fluctuations. These couplings provide superior protection for transmission systems, minimizing downtime and extending the service life of all connected components. No lubrication is required, significantly reducing maintenance efforts.

Product Details:

  • Advanced Materials & Compact Design
    The GUMMI BR couplings are made from cutting-edge materials, offering a more compact design compared to traditional elastic couplings. Despite their smaller size, they maintain the ability to absorb vibrations and torque fluctuations, protecting the transmission system and increasing the lifespan of key components.

  • Maintenance-Free Operation
    One of the standout features of the BR series is its maintenance-free design. With no need for lubrication, the coupling minimizes the need for corrective, preventive, and predictive maintenance actions, drastically reducing downtime—up to five times less than traditional couplings. Even when the elastic element needs to be replaced, there's no need to disassemble or move the connected transmission parts, further simplifying maintenance.

  • High Torque Capacity
    The BR-Series couplings can handle torque ranges from 4,000 Nm to 250,000 Nm, making them suitable for heavy-duty applications in various industrial settings. The design ensures reliable performance even under high torque conditions, providing long-lasting operation and enhanced protection.

  • Range of Sizes
    The BR-Series includes models ranging from BR-100 to BR-320, accommodating various power transmission requirements. This broad range of sizes ensures there is a solution for nearly any application where low rotation and high torque are key factors.

  • Applications:
    Ideal for a variety of low-rotation industrial applications, including conveyor belts, ball mills, slurry pumps, bucket elevators, redler conveyors, and more. These couplings are particularly useful in systems where torque fluctuation control and vibration damping are critical to maintaining smooth operation and minimizing wear.

  • Simple Installation & Replacement
    The BR coupling series is designed for easy installation. The compact design facilitates alignment and assembly, reducing setup time and simplifying the replacement of the elastic element without the need for complex disassembly. This saves both time and labor costs, making the couplings highly efficient for industrial use.

  • Certified Quality & Optional ATEX Certification
    GUMMI BR couplings are manufactured in compliance with ISO 9001 standards, ensuring top-tier quality. Additionally, they can be provided with ATEX certification upon request, meeting European directive 94/9/EC (ATEX 95) for use in explosive atmospheres.
