4-1 Installation Conditions
4-1-3 Decelerators
4-1-3 Decelerators
Installing Decelerators
• Use only the specified combinations of Servomotors and Decelerators. The service life
of the motor bearings may be shortened you use a combination that is not specified,
another company's reductions gear, or another company’s Servomotor.
• The dimensions of the Servomotor mounting flange on the Decelerators differ for each
Servomotor. Do not install Decelerators on a Servomotor other than the one specified.
• Use the following procedure when installing a Decelerator on the Servomotor.
• When installing the Servomotor, avoid the Servomotor shaft’s key groove when
installing the set bolt.

(1) Remove the rubber cap and check that the set bolt is loose.
(2) Insert the Servomotor shaft into the input shaft.
(3) Tighten the Servomotor installation bolt to the torque specified in the following table.

(5) After tightening the set bolt, replace the rubber cap.
Using Another Company’s Decelerator (Reference Information)
If the system configuration requires another company’s decelerator to be used in
combination with a SMARTSTEP Junior Servomotor, select the decelerator so that the
load on the motor shaft (i.e., both the radial and thrust loads) is with the allowable values.
(Refer to
3-2-2 Characteristics
for details on the allowable loads for motors.) Also, select
the decelerator so that the allowable input speed and allowable input torque of the
decelerator is not exceeded.
