The Rexnord Omega Metric 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. Omega couplings are non-lubricated, material-flexing couplings utilizing a specially formulated polyurethane material engineered for maximum durability, strength and fatigue resistance. The coupling's high-misalignment capacity accommodates unavoidable misalignment with low reactionary forces. The torsionally soft flex element cushions shock loads and vibration, extending equipment life. Hubs are available in rough bore, custom bore and bushed designs. Available in 16 sizes ranging from E2-M through E140-M and four interchangeable element types (see below), the Omega Metric close-coupled coupling accommodates torque loads up to 340,200 lb-in (38,442 Nm) and shaft diameters up to 9.00 inches (229 mm). Omega Metric couplings are identical to Omega couplings except that metric capscrews are used to attach the hubs.
- Standard (orange)
- HDY (Heavy Duty Yellow)
Features a 25% higher torque rating and a 40% higher torsional stiffness than the standard element.
Note: The misalignment rating is reduced to 2 degrees angular and .063" parallel for all sizes as compared to the standard element.
- HSU (Hydrolytically Stable Urethane) (green)
Features a shelf life that is twice the standard element.
- HSU-J Series (green)
Based on the HSU element but is enhanced with a proprietary phosphate coated anti-corrosive steel shoe and stainless steel hardware.
When configured with optional stainless steel hubs the Omega HSU-J coupling provides superior performance in corrosive environments.
