NM168<\/strong> is an NM flexible coupling size for industrial shaft connections. Its size data gives a first check for bore capacity, operating speed and torque. The finished hubs are machined to the actual shafts, so the driver and driven bores may be different.<\/p>\n

Specify both shaft interfaces<\/h2>\n

The coupling size does not define the finished bore. State the diameter, keyway and fit for Shaft 1 and Shaft 2 separately. If axial space is restricted, include the available hub envelope or an assembly drawing.<\/p>\n

Typical applications<\/h2>\n

NM couplings are commonly used on pumps, compressors, motor-to-gearbox drives, fans, blowers, mixers, conveyors and general industrial machinery. Application suitability depends on the complete duty and shaft interfaces.<\/p>\n
