Hollow Rotary Table (SHA)
Dynamic balanced clamp ring mechanism
- エラーのない取り付けとバランスの取れたクランプ システムにより、入力速度が向上し、動力伝達のバックラッシュがなくなりました。
Universal mounting motor flange
- 短納期での納品が可能となり、ステッピングモーターやサーボモーターへの取り付けも容易になります。
High torque & low backlash
- はすば歯車式遊星歯車装置です。
- ギヤ熱処理により耐摩耗性が向上。
Increased service life
- 総ころニードル遊星ベアリング。 （ソリッドアンケージ針状ころ軸受）
