  • No-load running torque will increase when the reducer is used at low temperature. Please be careful when selecting a motor.
  • If you require a reduction ratio other than the above, or if you have any questions regarding motor selection, please contact our sales representative.
  • The above specifications are based on our evaluation method. The customer is requested to use the product only after confirming that there are no problems under the operating conditions of the actual equipment to be installed.
  1. The rated torque is the torque value that corresponds to the rated lifetime when operating at the rated output rotation speed and does not indicate the upper limit of the load.
  2. The allowable moment changes depending on the axial load.

Reduction ratio

The reduction ratio i, which is the sum of the 1st and 2nd reduction parts, differs between output flange rotation and frame rotation.
