The Rexnord Omega is a unique general purpose elastomer
coupling with split element design providing easy assembly and
replace-in-place service. Available in close coupled and spacer
designs. These unique designs permits faster installation and reduced inveotories by providing multiple distance between shaft
ends using the same elements and hubs. Omega HDY coupling
torque ratings is 25% higher and torsional stiffness is 40% higher
than on standard Omega design.
Applications include:
- pumps
- conveyors
- industrial fans
