How to Select the Right Omega Size

Choosing the correct Omega coupling element depends on your torque requirements, shaft speed, and available space. Use this guide to quickly identify the right size range for your application:

E2 – E5

Compact, High-Speed — Up to 6,600 rpm. Ideal for light-duty pumps, small blowers, compact fan drives, and small-frame rotating equipment.

E10 – E50

Mid-Duty, Higher Torque — Torque from 1,450 to 7,650 in-lb. Standard pumps, compressors, industrial fans, and general rotating equipment.

E60 – E140

Heavy-Duty, Low-Speed — Torque from 12,500 to 340,200 in-lb. Large pumps, heavy compressors, extreme-duty conveyors, and the most demanding industrial drives.

Frequently Asked Questions

What is the difference between standard and spacer series?

Standard series elements are direct replacements for close-coupled couplings. Spacer series elements are used where additional shaft separation is required, accommodating larger equipment spacing and facilitating maintenance access.

Which size is best for a typical industrial pump?

For standard industrial pumps, E10 through E50 are commonly used. For larger, heavy-duty pumps, E60 through E140 are recommended. Consult our technical team for specific sizing based on your application.

Are these genuine Rexnord products?

Yes. Golden Bearing Company is an Authorized Regal Rexnord Distributor, supplying only genuine, OEM-sourced Rexnord Omega coupling elements. Every product is backed by full manufacturer warranty and traceability.

What is the maximum torque available in the Omega range?

The E140 delivers the highest torque in the Omega range at 340,200 in-lb (38,440 Nm) with a maximum speed of 1,500 rpm, making it suitable for the most demanding heavy industrial applications.
