Choose the NM size by torque, speed, shaft bore and installation envelope. NM50 through NM214 provide ten steps in capacity, with custom finished bores and keyways quoted for the actual driving and driven shafts.
Complete couplings, replacement elements and adjacent flexible-coupling families.
Use the complete NM range for new drives, or send the installed size and service details when you need a replacement flexible element or hub set.

Open the size that fits your first torque and bore check.
Each model includes its own dimensions, alignment values and RFQ guidance so you can verify the shaft interface before machining.
Specify the material from the service conditions, not from colour.
NBR is the standard flexible-element material for this range. If you need a different polymer or hardness, include operating temperature, oil or chemical exposure, starts and shock so the requirement can be reviewed.
Useful replacement details
Send the existing NM size, quantity, operating temperature if important, fluid or chemical exposure and clear photos of the hubs and element. For an unknown part, include measured dimensions as well.
Other flexible coupling constructions for different drive requirements.
HRC, pump-claw and star-style couplings can be quoted separately when your machine or replacement project calls for another coupling format.
HRC Couplings
A resilient coupling option for general machinery and shaft-to-shaft transmission requirements.
Pump Claw Couplings
A compact claw-style option for selected pump and motor connection requirements.
Star Flexible Couplings
A jaw-and-element construction for compact industrial drive applications.
