When it comes to flexible coupling solutions that deliver high torque transmission, low maintenance, and long service life, Rexnord Viva elastomeric couplings stand out as one of the most advanced and reliable designs available. Because of their performance and widespread industrial use, this product is frequently searched under the exact keyword Rexnord Viva elastomeric couplings — making it essential for engineers, procurement professionals, and maintenance teams to understand their advantages.

What Are Rexnord Viva Elastomeric Couplings?

Rexnord Viva elastomeric couplings are non-lubricated, split-in-half flexible tire couplings designed to connect rotating shafts for positive power transmission. Built for durability and vibration absorption, these couplings are ideal for industrial machines such as pumps, compressors, blowers, mixers, conveyors, and many other drive systems.

The Viva coupling builds on proven elastomeric coupling design, offering improvements in torque capacity, misalignment tolerance, and ease of service compared to earlier models.

Key Features of Rexnord Viva Elastomeric Couplings

Here’s why Viva elastomeric couplings are preferred across industries:

1. Easy Installation with Split-in-Half Flex Element

The unique split flex element allows simplified assembly and replacement without removing hubs or realigning equipment — cutting down on downtime and labor.

2. Excellent Vibration Damping

Torsionally soft polyurethane elements cushion shock loads and absorb vibration, protecting both the coupling and connected machinery during operation.

3. High Misalignment Capacity

Viva couplings accommodate angular and radial misalignment with low reactionary forces, reducing stress on bearings and seals.

4. Interchangeable Hubs for Reduced Inventory

Reversible and interchangeable hubs help lower stocking requirements, as the same components can fit different shaft spacing configurations.

5. Torque-Dense Elastomer Material

Specially formulated elastomer elements deliver superior torque capacity, allowing Viva couplings to transmit higher power relative to other elastomeric designs.

Benefits of Using Viva Elastomeric Couplings

Rexnord Viva elastomeric couplings provide several real-world advantages:

• Low Maintenance – The non-lubricated design eliminates the need for frequent greasing or adjustments, reducing maintenance costs.

• Extended Equipment Life – Vibration damping helps reduce wear on connected motors and driven equipment, improving overall reliability.

• Adaptable Sizes – Available in close-coupled and spacer configurations to fit various shaft gap requirements.

• Reduced Downtime – Quick installation and replace-in-place elements ensure machines return to service faster after maintenance.

Industrial Applications

Rexnord Viva elastomeric couplings are used in a wide range of sectors, including:

• Pumping Systems – for water, HVAC, slurry, and chemical pumps.

• Compressors & Blowers – where vibration control and continuous operation are critical.

• Mixers & Agitators – ensuring smooth torque transmission in process equipment.

• Manufacturing & Industrial Drives – including conveyors, material handling, and general drive systems.

These applications benefit from the coupling’s ability to handle misalignment, absorb shock, and transmit torque efficiently.
