Open solution →What an NM flexible rubber coupling does
An NM coupling joins a driving shaft and a driven shaft through two metallic hubs and a resilient ring. The ring in the supplied EVER-POWER catalogue is NBR rubber arranged around the hub jaws. It transmits torque while cushioning shock and damping torsional vibration. The same flexible interface can tolerate the limited radial and angular displacement stated for each size, but good installation still aims for accurate shaft alignment.
The documented range spans NM50 to NM214, nominal torque from 5 to 1000 N·m, maximum shaft diameters from 19 to 95 mm and catalogue speed limits of 1500 or 3000 rpm. These values define a comparison range, not an automatic motor-size schedule. A buyer must calculate or obtain design torque, account for the machine's duty, confirm both shafts and review temperature, chemicals, starts and peak loads.
EVER-POWER supports manufacturer, supplier, wholesale and OEM enquiries for NM couplings. Custom bore and keyway requests should include shaft drawings and fit requirements. The quotation must confirm hub material, flexible-ring compound details, machining, coating, balancing and inspection documents where needed. This evidence-led boundary is more useful than a broad claim because it tells engineers exactly what is known and what still needs approval.

NM coupling buyer questions
What is an NM coupling used for?
It connects rotating shafts in equipment such as pumps, gearboxes, fans, mixers, conveyors and compressors while adding damping and limited misalignment capacity.
What flexible element is used?
The supplied EVER-POWER catalogue identifies an NBR four-lobe flexible ring.
Can you customize bore size and keyway?
Yes, as a quotation-controlled option. Send both shaft drawings and required fits.
Which sizes are available in the catalogue?
NM50, NM67, NM82, NM97, NM112, NM128, NM148, NM168, NM194 and NM214.
What spider hardness should I choose?
The supplied NM page does not state hardness. Do not apply 92A/98A/64D colour rules from another coupling system without written compatibility confirmation.
How quickly will I receive a quote?
The site invites a response within 24 hours, but technical completeness depends on the duty and shaft information provided.
Do you have local offices in the target countries?
No local office, warehouse or stock claim is made. Supply is export-based unless a quotation states otherwise.
Can I import these pages into WordPress?
Yes. The deliverable includes publish-status CSV and XML files prepared for WP All Import mapping.
