The Rexnord Omega couplings, including the E-ES-ES-R series, are non-lubricated, material-flexing couplings that utilize a specially formulated polyurethane material. This material provides exceptional strength and fatigue resistance, capable of operating in ambient temperatures ranging from -40°F (-40°C) to +200°F (+93°C). The hubs are reversible, accommodating a variety of shaft spacing arrangements, and feature identical bolting patterns to allow for reduced inventory. The complete set for this hub typically refers to a Rexnord Omega E100 Complete Set = Rexnord Omega 100 HRB Hub x 2 + REXNORD Omega E100 Element x 1 (or ES100 for spacer configurations).

These specifications highlight the hub’s robust design, making the Rexnord Omega 100 HRB Hub a dependable choice for demanding industrial environments.

Key Features of Rexnord Omega E-ES-ES-R Series Couplings (of which the 100 HRB Hub is a part):

• Non-Lubricated Design: Reduces maintenance requirements and operational costs.
• Polyurethane Flex Element: A specially formulated material provides superior durability, strength, and fatigue resistance. This element effectively cushions shock loads and dampens vibration, extending the life of connected equipment.
• Split-in-Half Element Design: Facilitates simplified assembly and disassembly without disturbing the hubs or connected equipment, significantly minimizing downtime.
• Polyurethane-to-Metal Bond: Eliminates assembly and slippage problems often associated with mechanically clamped designs, ensuring a secure connection.
• Interchangeable and Reversible Hubs: Allows for reduced inventory and accommodates a variety of shaft spacing arrangements.
• High Misalignment Capacity: Tolerates angular, parallel, and axial misalignment with low reactionary forces, protecting machinery bearings.
• Versatile Operation: Capable of operating in both horizontal and vertical applications without the need for additional components.

Common Applications:

The durability and performance characteristics of the Rexnord Omega coupling series, including the Rexnord Omega 100 HRB Hub, make it suitable for a broad array of industrial applications. These couplings are extensively used across various sectors where reliable power transmission and shock/vibration dampening are critical:

• General Manufacturing: Pumps, fans, compressors, conveyors.
• Heavy Industries: Cement plants, mining operations, steel mills (e.g., runout tables).
• Process Industries: Food & Beverage (e.g., mash cookers in breweries), pulp & paper mills, oil & gas.
• Construction: Heavy machinery and equipment.
• Power Generation: Power plant applications.
• Specialized Machinery: Semiconductor manufacturing.

The Rexnord Omega 100 HRB Hub is a vital component of the complete Rexnord Omega 100 coupling set, working seamlessly with the appropriate elastomeric element (E or ES series, depending on the coupling style) to form a full assembly
