NM Coupling Insight

NM Coupling Size Reference: NM50 to NM214

Reference bore, speed and normal torque for NM50 through NM214.

Nm Coupling

This table keeps the current EVER POWER reference values in one place for first-pass model matching. It is intentionally short: bore range, maximum reference speed and normal torque. Final production machining and application selection still require the shaft and duty information in the RFQ.

Reference values support model matching. Finished bores, keyways and final application suitability are confirmed from the order data.

How to use the table

First exclude sizes that cannot accept either shaft. Then compare the actual operating speed with the reference maximum for the candidate size. Finally review torque or motor duty. If the installed unit is a replacement, include its marking and measured hub dimensions so a model-name mismatch can be caught before quotation.
