Note)
 1.The maximum rotating speed does not take dynamic balance into account.
 2.The weight, moment of inertia, and GD2 are given for the maximum bore diameter.
 3.Each allowable misalignment is based on the assumption that both of the other two misalignment values are zero.
 4.取付軸の推奨公差はh7です。但し、軸径Φ35は公差+0.010~0のサーボモータ軸に対応しています。
