Refer
to
the
ÒStandard
bore
diameter
and
the
transmission
torque
for
each
bore
diameterÓ
table
below.
Notes 1. The maximum rotation speed does not take dynamic balance into consideration.
2. The weight, moment of inertia and GD
2
are the values at maximum bore diameter.
3. The allowable misalignment is based on the assumption that other errors are Ò0Ó.
4. Bore diameters other than the standard diameters specified below can be manufactured upon request.
5. Depending on the bore diameter, the allowable torque of the coupling may be limited. Refer to the ÒStandard Bore Diameter and Transmission Torque for Each Bore
DiameterÓ table below.
6. The recommended tolerance of the mounting shaft is rated at Òh7Ó. A shaft diameter of φ 35 corresponds to a servo motor shaft with a tolerance of (+0.010 to 0).
