NM coupling performance starts with correct shaft interfaces. Bore diameter, keyway, fit, hub position and operating duty should be confirmed before production, especially when the coupling is replacing an older unit.<\/p>\n
| Item<\/th>\n | What to confirm<\/th>\n<\/tr>\n<\/thead>\n |
|---|---|
| Shaft data<\/td>\n | Actual shaft diameter, keyway dimensions and fit requirement on both sides.<\/td>\n<\/tr>\n |
| Coupling size<\/td>\n | NM model or measurable replacement dimensions when the marking is unavailable.<\/td>\n<\/tr>\n |
| Operating duty<\/td>\n | Speed, motor power or torque, driven machine, starts and reversing where relevant.<\/td>\n<\/tr>\n |
| Special requirements<\/td>\n | Material, marking, balancing or inspection documentation requested for the order.<\/td>\n<\/tr>\n |
| Order scope<\/td>\n | Quantity, mixed models and spare rubber elements required with the batch.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\nMachining and inspection<\/h2>\nBores and keyways are produced to the confirmed order information. Critical dimensions can be checked against the agreed drawing or dimensional requirement. Mixed-model orders should keep model identification clear from machining through packing.<\/p>\n \n Request an NM Coupling Quote<\/h2>\nSend the NM size if known, both shaft diameters, operating speed, driven equipment and quantity. Add a drawing or photos for replacement work.<\/p>\n |
