Rexnord Viva Elastomeric Couplings The most advanced 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.
Technical information
Easy replacement without moving the hubs or connected equipment.
Capscrews are easily accessible in tight spaces.
Optimal tensile strength and fatigue resistance.
Excellent chemical and environmental aging resistance.
No lubrication required.
Protects equipment by cushioning schock loads and dampening torsional vibration.
Accommodates unavoidable misalignment with low reactionary forces.
No need for coupling disassembly to inspect.
Close-coupled and spacer coupling hubs are identical allowing reduced inventories.
Construction
Split-in-half flex element design.
Radial bolting
