Note)
1．The maximum speed depends on the transmission capacity of the coupling. No balance adjustment has been conducted.
2．Standard stock shaft bore diameters in bold indicate standard hubs, figures enclosed in brackets are square hubs, and numerical model numbers are extended-diameter hubs.
3．The weight, moment of inertia, and GD2 are given for the maximum bore diameter of a round hub. The figures in parenthesis are for an extended-diameter hub for models NEF02, NEF04, and NEF45, and a square hub for models NEF10, NEF18, and NEF25.
4．The allowable axial displacement is based on the assumption that the angular misalignment is 0.
5．The square hub model uses a U-nut to prevent the clamping bolts from loosening. All other locations use Nylok bolts.
6．Refer to the table for the transmission torque of the clamp element. Contact us for information on shaft bore diameters not listed in this table.
7．Contact us when mounting on a hollow shaft.
8．The torsional rigidity listed above is only for the disks.
