Rexnord OMEGA-E4-ELEMENT, Polyurethane Coupling Element, Set Screw

The OMEGA E4 Element from Rexnord is a split‑half, close‑coupled polyurethane‑elastomer insert designed for flexible shaft coupling systems in industrial drive equipment. Built for continuous torque of approximately 62 Nm (550 in‑lbs), a maximum speed around 6,600 rpm and bond‑to‑metal construction, this element delivers reliable performance in high‑misalignment, shock‑load and vibration‑intensive environments.

Engineered for Durable Drive‑Train Performance

Designed with industrial reliability in mind, the OMEGA E4 Element applies urethane‑to‑metal bonding to create a robust flex element that remains dimensionally stable under cyclic loading, start/stop duty and misalignment. The material choice and design yield significantly improved fatigue life, diminished maintenance intervals and lower total cost of ownership, particularly in applications subject to dynamic loads and thermal/chemical stress.

Possible Advantages of Choosing the Rexnord Polyurethane Coupling Element

• High‑performance urethane bonded to metal hub halves, reducing fretting wear and increasing longevity.
• Split design (two halves) enables installation/replacement without hub removal or full realignment of connected components.
• Excellent misalignment tolerance and vibration damping thanks to the elastomeric element, protecting shafts and bearings.
• Polyurethane material offers superior toughness, chemical/ozone resistance, fatigue life and stability compared to typical rubber inserts.
• Standard set‑screw style mounting ensures secure hub‑to‑shaft connection and straightforward mechanical integration.

Versatility in Applications

• Coupling insert for close‑coupled elastomeric couplings in motor‑driven machinery.
• Replacements for worn or damaged coupling elements in industrial drive systems.
• Applications subject to moderate torque, misalignment, vibration or shock (e.g., pumps, blowers, conveyors).
• Retrofit programmes where maintenance downtime must be minimised via a split‑half design.
• Compact mechanical systems requiring space‑efficient coupling components with high reliability.
• Environments where oil, ozone, chemical exposure or thermal cycling could degrade traditional rubber inserts.
