Rexnord Omega E5 Elastomeric Coupling Element – Product Overview
The E5 element fits Rexnord Omega E5 close-coupled flexible couplings and represents the highest-torque option in the compact E2–E5 sub-group before the Omega range transitions to double-digit sizes. Its split urethane design absorbs shock, dampens vibration, and tolerates shaft misalignment, while the split-element construction allows in-place replacement without disturbing connected equipment.
Matching HRB (pilot bore) hubs, finished bore hubs, and complete E5 coupling assemblies are also available from Golden Bearing Company.
Compatibility
The Rexnord Omega E5 Elastomeric Coupling Element is compatible with the following components:
- • Omega E5 Close-Coupled Couplings
- • Omega E5 HRB (Pilot Bore) Hubs
- • Omega E5 Finished Bore Hubs
- • Complete Omega E5 Coupling Assemblies
Compatibility depends on proper hub selection and application conditions. Contact our technical team for selection assistance.
Rexnord Omega E5 Elastomeric Coupling Element – Industrial Applications
Its position as the highest-capacity compact-range element suits the E5 to:
- • Mid-size NEMA-frame pumps
- • Compressors requiring higher torque in a compact footprint
- • Industrial fans and blowers at the upper end of light-duty service
- • Standard-duty conveyors and mixers
- • General rotating equipment nearing the compact-range torque ceiling
Application suitability depends on operating conditions, torque requirements, shaft alignment, and OEM recommendations.
Frequently Asked Questions
The Rexnord Omega E5 is the highest-capacity compact elastomeric coupling element designed for close-coupled flexible couplings in industrial applications requiring maximum torque within the E-series footprint.
