3. The reduction gear efficiency differs depending on the reduction ratio.
Also, it changes depending on the use conditions such as the output torque, speed and rotation, temperature, etc. The
numerical value in the table is a typical value in the rated torque, rated speed and rotation and typical temperature, and
not a guaranteed value.
