Additional Machining

You can freely choose the connection type during assembly, with a maximum applicable torque of up to 385.6 N⋅m.

The values of static torsional rigidity, moment of inertia, and weight are given for the maximum shaft diameter.
Eccentricity, angular deviation, and axial amplitude are all individual allowable values. If multiple types of deviations occur at the same time, the allowable value for each deviation is reduced to half of the original value.
For selection criteria and calibration adjustment, please refer to P.788·789.
Eccentricity is not allowed for single disc type.
