Note   1.  If the above indicated value is exceeded, please contact your local sales office. 
 

  2.  The reducer efficiency differs depending on the reduction ratio. Also, it changes depending on the 

operating 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. 

 

  3.  The backlash can be converted: 1 min = 0.0167 °
