Omega Elastomeric Coupling – ES Series



  • Sizes: ES 2 to ES80
  • Torque Value: 22 – 4460 Nm


  • The Rexnord Omega 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.
  • 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.
  • The Omega spacer design features optional hole mounting positions and reversible hubs to allow adjustment to accommodate most shaft spacing requirements.
  • Optional sleeve extensions 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.
  • Sleeve extensions are furnished in steel and mount to Omega spacer elements and also size E100 to E140 close-coupled elements. Available in 13 sizes ranging from ES2 through ES80 and four interchangeable element types (see below), the Omega Spacer coupling accommodates torque loads up to 39,500 lb-in (4,463 Nm) and shaft diameters up to 6.00 inches (155 mm).​
