Rexnord Omega E120 Elastomeric Coupling Element – Product Overview
The E120 element fits Rexnord Omega E120 close-coupled flexible couplings and delivers exactly double the torque capacity of the E100 in a 25 in diameter package, representing one of the largest single-step torque increases in the Omega range. 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 E120 coupling assemblies are also available from Golden Bearing Company.
Compatibility
The Rexnord Omega E120 Elastomeric Coupling Element is compatible with the following components:
- • Omega E120 Close-Coupled Couplings
- • Omega E120 HRB (Pilot Bore) Hubs
- • Omega E120 Finished Bore Hubs
- • Complete Omega E120 Coupling Assemblies
Compatibility depends on proper hub selection and application conditions. Contact our technical team for selection assistance.
Rexnord Omega E120 Elastomeric Coupling Element – Industrial Applications
The E120’s extremely high torque capacity and 1,800 rpm speed ceiling suit it to the most demanding, low-speed heavy industrial applications, including:
- • Very large industrial pumps in extreme heavy-duty, low-speed service
- • Extremely high-torque compressors
- • Massive slow-speed fans and blowers
- • Heavy-duty conveyors and mixers under extreme sustained loads
- • General heavy industrial rotating equipment where maximum torque capacity is the primary specification driver
Application suitability depends on operating conditions, torque requirements, shaft alignment, and OEM recommendations.
