NM 67 expands the reference bore range to 8-28 mm while keeping a 67 mm outside diameter. The supplied table lists 2.2 Kg*m normal torque, 4 Kg*m maximum torque, a 10,000 rpm maximum reference speed and an approximate 1.02 kg weight. It is a useful comparison point when NM 50 is too small for the shaft but the installation still favors a compact hub envelope.<\/p>\n

    Step-Up Size Review<\/h2>\n

    The row below is a matching reference for NM 67. It is intentionally separated from the application review because a model-table match does not by itself establish service suitability.<\/p>\n

    Hub And Element Layout<\/h2>\n

    The NM 67 reference construction is a two-hub jaw arrangement with a flexible element between the hubs. The source illustration labels the hub as forged iron. For purchasing, the material label should be separated from the unverified element specification: the provided model table does not state the elastomer grade. If the coupling operates near oil mist, heat, washdown chemicals or frequent cycling, describe those conditions so the element can be reviewed deliberately.<\/p>\n

    Shaft First Selection<\/h2>\n

    On NM 67, shaft diameter often becomes the early gate. Check the larger of the two shafts against the 28 mm reference maximum, then examine the required keyway and the remaining hub section. After geometry, calculate or provide the real transmitted torque and compare the running speed with the reference limit. A shaft that fits does not prove that the torque duty fits, and a torque value that looks low does not prove the requested bore can be machined safely.<\/p>\n
