Rexnord Viva Elastomeric Couplings

The most advaced elastomeric coupling available

Rexnord Viva Elastomeric Couplings feature a design based on the proven Rexnord Omega Couplings. Design upgrades to Viva allow for greater torque transmission with a smaller coupling. Incorporating the quality features of Omega, Rexnord Viva Couplings are non-lubricated, material-flexing split-in-half tire couplings. Viva Couplings are built for reliability in a variety of demanding applications including pumps, compressors, blowers, mixers, and more. This all-purpose coupling has excellent vibration damping capability helping to prolong the life of connected equipment.

Split-in-half design for easy assembly and replacement without having to remove the hubs. No need to realign equipment.
Torsionally soft weight balanced flex elements cushions shock loads and vibration to protect and extend connected equipment.
Radial Bolting provides easier access than axially bolted couplings in confined areas. Metric hardware available in standard carbon steel, or stainless steel.
High-misalignment capacity accommodates unavoidable misalignment with reduced reactionary forces on connected equipment.
Interchangeable hubs allow for reduced inventory. Hubs available in carbon steel, 303-304 stainless steel, or with electroless nickel plating. Two rows of radial holes grant more field spacing adjustability.
Specially formulated polyurethane allows for greater torque with a smaller sized coupling.
"V" notch design in the polyurethane flex element channels stresses to provide a uniform center-line tear for overload protection.

More About Viva Elastomeric Couplings

What makes Viva different from the rest?

The most torque-dense elastomeric coupling

Resistance to Chemical & Environmental Aging

Viva’s specially-formulated polyurethane provides superior chemical and environmental aging resistance as compared to competitive rubber-based solutions.

Torque-Dense Flex Elements

Viva’s specially formulated polyurethane is the most torque-dense elastomeric coupling available. It provides significantly higher torque capabilities than competitive rubber-based solutions, allowing the use of a smaller sized coupling and ultimately a lower Total Cost of Ownership (TCO).
 

No Special Hubs or Sleeves Needed for Extra Wide Gaps

Viva Extended Spacer (VSX) version connects shafts with extra wide gaps (up to 300 mm) with the basic four component design of two axially-split half flex elements and two hubs. No special hubs or sleeves required.

Weight Balanced Elements

Viva element halves are tightly matched to ensure standard weight balance conforms with ISO G16 (1504 RPM) and AGMA Class 8; helping prevent premature wearing due to an unbalanced coupling.
