Attention
When mounting the load shaft to hollow shaft, do not damage the hollow shaft
and the load shaft.
• Apply grease (Molybdenum grease, etc.) on the surface of the load shaft surface
and the hollow shaft inner surface for prevent heat damage.
• Do not machining and modification hollow shaft. The gearhead may be broken
due to shaft may damage.
• If the motor is subject to a large overhung load, please use stepped load shaft.
6.4.5 Rotation direction of gearhead and transmission efficiency
▣ Rotation direction of gearhead
When viewed from the front view and the rear view, the rotation direction of hollow shaft is
different.
▣ Transmission efficiency of gearhead

※ (Gearhead torque = Motor qorque X gear ratio X Transmission efficiency of gearhead)
6.4.6 Maximum permissible torque of gearhead
The output torque of the gearhead varies greatly in proportion to the gear ratio, but the load
torque applied to the reducer is limited by the gear material and other conditions.
This is defined as the maximum permissible torque and is based on the size of gearhead and gear
ratio of the gearhead. Use it within permissible torque range.
