Viva Elastomeric Couplings

Request Information

Rexnord Viva Elastomeric Couplings are non lubricated, material-flexing couplings, which are used in a variety of applications in many industries. They have excellent vibration dampening capability and high-misalignment capacity, providing extended life to connected equipment. This coupling offers a torsionally soft, split-in-half, easy maintenance flexible element coupling that ensures on-site adjustability.

 

Features & Benefits:

  • Mounting hole patterns allow for a wide range of shaft gaps
  • 12 sizes available
  • Up to 11 inches (279 mm) bore capacity
  • Up to 340,200 in-lb (38,440 Nm) torque capacity
  • Up to 7,500 rpm
  • ATEX certified
  • Radial bolting
  • Non-lubricated and low-maintenance
  • Patented "V" notch design provides uniform failure area for overload protection
     
Rexnord Viva Close-Coupled Elastomeric Couplings
Rexnord Viva Close-Coupled Elastomeric Couplings
The Rexnord Viva close-coupled elastomeric coupling consists of a unique split-in-half flex element and reversible hubs that significantly decrease total costs by reducing inventory and assembly time. Viva couplings are non-lubricated, material-flexing couplings utilizing a specially formulated polyurethane material engineered for maximum durability, strength and fatigue resistance. The couplings high-misalignment capacity accommodates unavoidable misalignment with low reactionary forces. The torsionally soft flex element cushions shock loads and vibration, extending equipment life. The Rex Viva "V" notch design directs stress concentration away from the bonded area thus providing superior performance and seamless overload protection, if required. Hubs are available in rough bore, custom bore and bushed designs. Available in 12 sizes ranging from 110 through 460, the Viva close-coupled coupling accommodates torque loads up to 55,494 lb-in (6,270 Nm) and shaft diameters up to 6.5 inches (165 mm).

Rexnord Viva Extended Spacer Elastomeric Couplings
The Rexnord Viva extended spacer elastomeric coupling consists of a unique split-in-half flex element and reversible hubs that significantly decrease total costs by reducing inventory and assembly time. Viva couplings are non-lubricated, material-flexing couplings utilizing a specially formulated polyurethane material engineered for maximum durability, strength and fatigue resistance. The couplings high-misalignment capacity accommodates unavoidable misalignment with low reactionary forces. The torsionally soft flex element cushions shock loads and vibration, extending equipment life. The Rex Viva "V" notch design directs stress concentration away from the bonded area thus providing superior performance and seamless overload protection, if required. Hubs are available in rough bore, custom bore and bushed designs. Rex Viva VSX extended spacer couplings are designed to connect equipment with shaft gap (distance between shaft end) requirements beyond the Viva spacer coupling capabilities. They are ideal for applications with wide non-standard shaft gaps and can be an economic alternative to suit all shaft spacings up to the maximum allowable gap with the same coupling components. The Viva VSX adjustable spacer design features optional hole mounting positions and reversible hubs to allow adjustment to accommodate most shaft spacing requirements. Available in 12 sizes ranging from VSX110 through VSX460, the Viva extended spacer coupling accommodates torque loads up to 55,494 lb-in (6,270 Nm) and shaft diameters up to 6.5 inches (165 mm).
