Product Overview
The E100 element fits Rexnord Omega E100 close-coupled flexible couplings and sits near the top of the Omega standard range, delivering over double the torque capacity of the E80 in a 21 in diameter package. 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 E100 coupling assemblies are also available from Golden Bearing Company.
Industrial Applications
The E100’s extremely high torque capacity and 1,900 rpm speed ceiling suit it to the most demanding heavy industrial applications, including:
- • Very large industrial pumps in heavy-duty, low-speed service
- • Extremely high-torque compressors
- • Very large slow-speed fans and blowers
- • Heavy-duty conveyors and mixers under maximum sustained loads
- • General heavy industrial rotating equipment where torque is the dominant specification
Application suitability depends on operating conditions, torque requirements, shaft alignment, and OEM recommendations.
