German OEM and maintenance enquiries commonly use metric shaft drawings and formal drawing revisions. Include the exact bore and keyway dimensions, NM model if known, operating speed and any DIN\/EN requirement stated on the machine or purchase drawing.<\/p>\n
| Item<\/th>\n | What to confirm<\/th>\n<\/tr>\n<\/thead>\n |
|---|---|
| Dimensional basis<\/td>\n | Use the units shown on the controlled drawing; metric dimensions are common.<\/td>\n<\/tr>\n |
| Identification<\/td>\n | NM model, existing marking or measured replacement dimensions.<\/td>\n<\/tr>\n |
| Duty<\/td>\n | Speed, motor power or torque and driven equipment.<\/td>\n<\/tr>\n |
| Documentation<\/td>\n | Drawing revision, inspection request or specified standard where required.<\/td>\n<\/tr>\n |
| Order scope<\/td>\n | Quantity, mixed models and spare rubber elements.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\nTypical project use<\/h2>\nNM couplings are commonly considered for pump, compressor, motor-to-gearbox, fan, mixer, conveyor and general industrial drives. The final coupling size and machining details should match the actual shaft interfaces and operating duty for the machine.<\/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 |
