NM214 technical data<\/h2>\n<\/div>\n

NM214 is the largest listed NM size, rated at 1000 N.m nominal torque with a 95 mm maximum bore. Its role is straightforward: it provides the highest capacity in this range, but the machine must also accept a 214 mm diameter, 110 mm length and 1500 rpm speed limit.<\/p>\n<\/div>\n

Large shafts make bore geometry critical. Provide the actual 95 mm-or-smaller shaft dimensions, keyways, fits and shoulders rather than a rounded nominal size. Also confirm the guard and adjacent structures can clear the full coupling envelope.<\/p>\n<\/div>\n

Use NM214 only when the higher capacity is justified by the real torque and shaft interface. Large pumps, process drives and compressor-related machinery may fall into this class, but starts and transient loads still need to be stated for the application.<\/p>\n<\/div>\n<\/div>\n<\/section>\n

Set the model to S 4.0 +\/- 2.0 mm and keep radial misalignment within 0.10 mm and angular misalignment within 2.0 degrees. On large machinery, re-check these values after the final base, piping and connected-equipment loads are applied.<\/p>\n

Prepare the NM214 RFQ<\/h2>\n

An NM214 enquiry should include running rpm, design torque or motor power, both shaft diameters and keyways, quantity, destination and any controlled fit or material request. Drawings are recommended when the bores or shoulders are close to the model envelope.<\/p>\n

NM214 has no larger model in this listed NM range. If its 1000 N.m torque or 95 mm bore is still insufficient, the application should move to a different coupling selection rather than assuming another NM size exists.<\/p>\n
