Couplers & Bearing E10 Coupler

The Rexnord Omega E10 Coupler is a high-performance elastomeric coupling element designed for demanding HVACR and industrial applications. This orange urethane element features a unique split-in-half flex element design, allowing for rapid "replace-in-place" installation without disturbing hubs or moving connected equipment like motors or pumps. Engineered for high misalignment capacity, it effectively dampens vibration and shock loads, significantly extending the service life of bearings and seals. With a continuous torque rating of 1,450 in-lb (164 Nm) and a maximum speed rating of 6,600 RPM, the E10 is a torsionally soft solution that resists petroleum products and most industrial chemicals. As a direct replacement for E10 units, it ensures 100% compatibility with existing Omega close-coupled hubs. This non-lubricated flexible coupling is weight-matched at the factory to maintain precise balance and reduce noise in high-speed mechanical drive systems.

• Reduced Downtime: The split-element design allows for element replacement without unbolting the motor or pump, saving hours of labor on-site.
• Superior Damping: Specially formulated polyurethane material absorbs torsional vibrations and cushions shock loads better than standard rubber couplings.
• Accommodates Misalignment: Capable of handling significant angular and parallel misalignment to protect sensitive couplers and bearings.
• Chemical Resistance: The urethane flex element is not seriously affected by oils, greases, or common HVAC solvents.
• Maintenance-Free: Non-lubricated design eliminates the need for periodic greasing and prevents potential leaks.

• Can I replace just one half of the E10 element? No. Rexnord Omega elements are weight-matched in pairs at the factory. Replacing only one half will cause imbalance and premature wear on your couplers and bearings.
• What is the proper cap screw torque for the E10 size? For the Rexnord Omega E10, cap screws should be tightened to 204 in-lb to ensure a secure polyurethane-to-metal bond during operation.
• Is this element compatible with spacer hubs? This specific E10 element is designed for close-coupled configurations. While hubs are often interchangeable, ensure your "Distance Between Shaft Ends" (DBSE) matches the element style.
