Product Overview
The E40 element fits Rexnord Omega E40 close-coupled flexible couplings and continues the torque-for-speed trade-off that begins at E30 — each step up in torque capacity through this part of the range comes with a corresponding reduction in maximum rated speed. 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 E40 coupling assemblies are also available from Golden Bearing Company.
Industrial Applications
The E40’s higher torque and lower speed ceiling suit it to slower, heavier-duty rotating equipment, including:
- • Large industrial pumps operating at moderate to low speeds
- • Heavy-duty compressors with high continuous torque demand
- • Large fans and blowers on slower drive trains
- • Heavy conveyors and mixers
- • General rotating equipment where speed is secondary to torque capacity
Application suitability depends on operating conditions, torque requirements, shaft alignment, and OEM recommendations.
