Rexnord Falk Omega Elastomeric Coupling Summary
The Rexnord Falk Omega elastomeric coupling is a non-lubricated, material-flexing coupling known for its split-in-half flex element and reversible hubs. This design simplifies installation and maintenance by allowing element replacement without disturbing connected equipment or hubs, ultimately reducing downtime and inventory costs. Utilizing a specially formulated polyurethane material, Omega couplings offer excellent durability, strength, and fatigue resistance, effectively cushioning shock loads and vibrations to extend the lifespan of connected machinery. They accommodate significant misalignment with low reactionary forces and can operate in both horizontal and vertical orientations. The polyurethane-to-metal bond eliminates slippage issues common in mechanically clamped designs. Available in various sizes and configurations, Omega couplings are a versatile solution for a wide range of industrial applications. Â
Available Models and Product Names:
The Rexnord Falk Omega series includes several models based on their design and material:
Close-Coupled: Designed for standard shaft spacing.
Omega Close-Coupled Orange Couplings (Standard polyurethane for general purpose) Â
Omega Close-Coupled Yellow (HDY) Couplings (Heavy Duty Yellow polyurethane for 25% higher torque capacity) Â
Omega Close-Coupled HSU (Hydrolytically Stable Urethane) Couplings (Green polyurethane for hot, humid, or corrosive environments) Â
Spacer: Accommodates larger distances between shaft ends (DBSE).
Omega Spacer Orange Couplings Â
Omega Spacer Yellow (HDY) Couplings Â
Omega Spacer HSU Couplings Â
Half Spacer: Provides an intermediate spacer length.
Extended Spacer: For even larger DBSE requirements.
Mill Motor: Specifically designed for mill motor applications.
Each of these designs is available in various sizes, both in imperial (E2 to E140, ES2 to ES80) and metric (E2-M to E140-M, ES2-M to ES80-M) versions, to suit different torque and bore requirements. Hubs are offered in straight bore, QD (Quick Disconnect), and TAPER-LOCK® bushing styles, and can be made from carbon steel, 303-304 stainless steel, or with electroless nickel plating. Â
Key Facts:
Split-in-Half Flex Element: Facilitates easy installation and replacement without moving hubs or equipment. Â
Reversible Hubs: Accommodate different shaft spacing and allow for compression bushing installation from either side. Â
Non-Lubricated: Reduces maintenance requirements and costs.
High Misalignment Capacity: Tolerates angular, parallel, and axial misalignment, minimizing reactionary forces. Â
Torsionally Soft: Dampens shock loads and vibration, protecting connected equipment. Â
Polyurethane Construction: Offers excellent durability, strength, and resistance to fatigue and some chemicals. Specific formulations (Orange, Yellow HDY, Green HSU) cater to different operating conditions.
Interchangeable Hubs: Reduces inventory needs as the same hubs can be used with different element types (close-coupled or spacer). Â
Radial Bolting: Provides easier access for hardware in confined spaces compared to axially bolted couplings.
Polyurethane-to-Metal Bond: Eliminates potential slippage between the element and metal shoes.
