GUMMI A-Series Elastic Tire Couplings

Prolonged Equipment Life and Enhanced Transmission Efficiency

The GUMMI A-Series Elastic Couplings are designed to absorb both misalignments and vibrations, which are responsible for over 50% of bearing failures. By compensating for misalignment and dampening vibrations, these couplings help prolong the lifespan of machine components, reduce maintenance costs, and increase system reliability. Featuring easy installation and replacement, they are ideal for a wide range of industries, including steel, paper, food, petroleum, marine, and mining.

Product Details:

Misalignment and Vibration Absorption
GUMMI A-Series couplings compensate for shaft misalignment, reducing the risk of bearing and seal failures. With an elastic center, these couplings minimize transmitted vibrations by about 70%, ensuring a longer lifespan for transmission components.
High Torque Capacity
With torque ranges from 38 Nm to 168,750 Nm, the GUMMI couplings handle demanding industrial applications, ensuring reliable power transmission and reducing downtime due to mechanical failure.
Multiple Configurations
Available in a wide variety of sizes from A-20 to A-400, the GUMMI A-Series couplings also come with optional synthetic coating for use in aggressive environments (RE). The couplings offer various hub designs such as standard hubs (CN), integral hubs (CI), axial hubs (CX), and flanged hubs (CF). Special configurations are available with brake discs (DF) and brake pulleys (APF), providing flexibility for different applications.
Durable and Maintenance-Free Design
The construction of these couplings ensures symmetry, balance, and safety, as the elastic center is free of cuts or weak points. No lubrication is required, reducing maintenance efforts and extending the service life.
Applications:
Thanks to their versatility, GUMMI A-Series couplings are widely used in industries like steel, paper production, food processing, petroleum, mining, and marine sectors. They are especially beneficial in systems with diesel engines, axial displacement, and large-diameter shafts.
Easy Installation and Replacement
The coupling consists of a single elastic element, which makes installation and replacement quick and easy. There is no need to move other parts during replacement, minimizing machine downtime.
Quality Assurance
All GUMMI products are manufactured in accordance with ISO 9001 quality standards. With over 45 years of industry experience, GUMMI guarantees the highest quality materials and technical support to ensure superior performance.
No Lubrication Required
The couplings are constructed from materials that eliminate the need for lubrication, which further simplifies maintenance and reduces operational costs.
Economy and Efficiency
The long service life of the elastic center helps to extend intervals between replacements, reducing downtime and saving on spare parts, lubricants, and inventory costs.
