Product Overview
The E3 element fits Rexnord Omega E3 close-coupled flexible couplings, offering roughly double the torque capacity of the E2 in a modestly larger 4 in (102 mm) envelope. The 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 E3 coupling assemblies are also available from Golden Bearing Company.
Industrial Applications
The E3’s higher torque capacity relative to the E2, combined with its unchanged high-speed rating, suits it to:
- • Small-to-mid NEMA-frame pumps
- • Light industrial compressors and blowers
- • Fans requiring moderate torque at high speed
- • Light-duty conveyors and mixers
- • General small-to-mid frame rotating equipment
Application suitability depends on operating conditions, torque requirements, shaft alignment, and OEM recommendations.
