Rexnord V Series Viva Elastomeric Couplings
Rexnord V Series Viva Elastomeric Couplings
The Rex Viva Elastomeric Coupling (yellow) is a unique split-in-half flex element design featuring specially formulated polyurethane material engineered for maximum durability, strength and fatigue resistance. Viva couplings are non lubricated material flexing couplings available as close-coupled with rough bore, custom bore, or bushed designs. Torsionally soft polyurethane element cushions shock loads, accomodates misalignment and is compatible with most operating environments. These couplings can also be ordered with extended spacers and/or sleeve extensions for applications requiring increased distances between shaft ends (DBSE). The Rex Viva "V" notch design directs stress concentration away from the bonded area thus providing superior performance and seamless overload protection, if required. Available in 12 sizes ranging from 110 through 460, the Viva Coupling is engineered to accomodate torque loads up to 6,270 Nm (55,494 lb-in) and shaft diameters up to 165 mm (6.5 inches).
