Features
• Supplied with metric fasteners • Hubs offered in rough bore, custom bore, and bushed designs • Connects equipment with shaft gap (distance between shaft end) up to 5.2” (132mm) • Accommodates shaft diameters up to 6.5” (165 mm) • Continuous torque loads up to 55,494 lb-in (6,270 Nm) • Available in 12 sizes ranging from 110 through 460Resistance 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.Specifications
