Use this NM50\u2013NM214 table for a first size check. Compare bore capacity, reference maximum speed and reference normal torque, then confirm the finished bores and actual machine duty before ordering.<\/p>\n

Use the table to narrow the NM size. Finished bores, keyways and application duty are confirmed for the ordered configuration.<\/p>\n \n

How to use the table<\/h2>\n

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.<\/p>\n

Send the shaft sizes, speed, duty and quantity. We will review the model and machining details before quotation.<\/p>\n
