Rexnord Omega & Viva Elastomeric Couplings - The Industry Benchmark: Rexnord Omega and Viva elastomeric tire hub couplings are well recognized as the industry benchmark for elastomeric tire couplings. These non-lubricated, material-flexing, split-in-half couplings are used in a variety of demanding applications. Omega and Viva elastomeric tire hub couplings have an excellent vibration damping capability, helping to extend the life of your connected equipment. They offer high-misalignment capacity, easy installation, and replace-in-place design while accommodating a wide range of shaft gaps. Omega and Viva elastomeric tire hub couplings are available in a variety of sizes (metric and imperial) and spacing options (close-coupled, spacer, half-spacer, and extended spacer). These elastomeric tire hub couplings are also available with anti-corrosive coated steel shoes, stainless steel hardware/hubs, spline bore hubs, keyless/internal locking device hubs, and positive drive with interlocking hubs. Omega coupling tire hub and elastomeric elements are available in general purpose Standard Orange, High Density Yellow (HDY), and Hydrolytically Stable Urethane (HSU) Green. Omega and Viva's specially formulated polyurethane provides superior chemical and environmental aging resistance as compared to competitive rubber-based solutions. The Omega and Viva elastomeric tire hub coupling families have been used for over 45 years in a wide assortment of demanding applications and are recognized in industry as the benchmark for elastomeric split-in-half tire couplings.
