Regal Rexnord couplings
Rexnord Omega Elastomeric Couplings
Rexnord Omega elastomeric couplings - E-series close-coupled and ES-series spacer configurations with verified torque, speed and bore data in the family catalogue.
Omega coupling overview
Rexnord Omega elastomeric couplings transmit torque through replaceable polyurethane elements between two steel hubs. The design accommodates misalignment and dampens torsional vibration in motor-driven equipment.
Golden Bearing Company is an authorised Regal Rexnord distributor. Omega is a Rexnord-branded family — not a Falk portfolio product.
Standard vs spacer configuration
Close-coupled (standard) hubs mount directly with minimal shaft gap. Spacer configurations use a tubular spacer for pump maintenance access; DBSE dimensions are catalogue-defined for ES-series layouts.
ES-series spacer designations
ES designations denote spacer variants with defined distance between shaft ends for pump maintenance layouts. Rated torque, speed and bore summaries for verified ES sizes appear in the catalogue table below as engineering reference. Spacer sizes follow the same torque class numbering as E-series close-coupled hubs but use different hub and spacer assemblies.
Engineering characteristics
Rated torque, maximum speed, bore capacity and misalignment limits are listed per size in the catalogue table below and on linked product pages where available, sourced from verified Regal Rexnord catalogue data. Element compounds vary for temperature and chemical exposure (standard, heavy-duty and high-speed polyurethane options per manufacturer tables).
Applications
Pumps, compressors, blowers, fans, conveyors, mixers and general industrial drives where periodic element replacement is preferred over metal fatigue in the flexible member.

Omega configurations
E series
Close-coupled
Minimum distance between shaft ends; common on close-coupled pumps and fans. Verified E designations with rated torque, speed and bore in the catalogue below. Published sizes link to full Golden Bearing Company product pages; other rows are engineering reference.
ES series
Spacer
Removable spacer tube for pump seal and bearing maintenance. ES hubs and assemblies are distinct from E close-coupled lines. Verified ES torque, speed and bore summaries are listed in the catalogue below as engineering reference.
Element replacement
Polyurethane elements can be replaced without moving major equipment on many sizes.
