NM97 technical data<\/h2>\n<\/div>\n

NM97 is a useful transition size: it carries 45 N.m nominal torque and accepts bores up to 42 mm, a meaningful jump from NM82. That extra shaft capacity is often the reason to consider it, so the keyway and remaining hub section deserve attention.<\/p>\n<\/div>\n

The main envelope grows to 97 mm diameter and 50 mm length. Confirm guard clearance and the shaft-to-shaft space before approving a larger bore, especially on replacement drives where the previous coupling may have been shorter.<\/p>\n<\/div>\n

Use the 45 N.m rating and 3000 rpm limit for initial screening, then describe starts, reversing and shock. NM97 can suit pump, blower and machine duties that need more bore capacity than the smaller sizes without yet moving into the heavier mid-range group.<\/p>\n<\/div>\n<\/div>\n<\/section>\n

The specified hub separation is 3.0 +\/- 1.0 mm. Radial misalignment is limited to 0.05 mm and angular misalignment to 2.5 degrees, so a machine that cannot hold alignment should be corrected rather than upsized as a workaround.<\/p>\n

Prepare the NM97 RFQ<\/h2>\n

For NM97, include the actual bore and keyway on each side plus any drawing-controlled fit. Add the running speed and driven-equipment description so the 42 mm bore capacity is not reviewed in isolation from torque.<\/p>\n
