Installing Decelerators
Use only the specified combinations of Servomotors and Decelerators. (Refer to Decelerator
Specifications on page 3-26.) The service life of the motor bearings may be shortened if you use
a combination that is not specified, another company’s decelerator, or another company’s
servomotor.
The dimensions of the Servomotor mounting flange on the Decelerators differ for each
Servomotor. Do not install a Decelerator 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.
Installing an R88G-HPG@ (Backlash = 3’ Max.)
Use the following procedure to install the Decelerator on the Servomotor.
1. Turn the input joint and align the head of the bolt that secures the shaft with the
rubber cap.
2. Apply sealant to the installation surface on the Servomotor (recommended sealant:
Loctite 515).
3. Gently insert the Servomotor into the Decelerator.
As shown in the figures on the next page, stand the Decelerator upright and slide down the
Servomotor shaft into the input shaft joint while making sure it does not fall over. If the Decelerator
cannot be stood upright, tighten each bolt evenly little by little to ensure that the Servomotor is not
inserted at a tilt.
4. Bolt together the Servomotor and the Decelerator flanges.

5. Tighten the input joint bolt.
Bolt Tightening Torque for Duralumin
Note Always use the torque given in the table above. The Servomotor may slip or other problems
may occur if the specified torque level is not satisfied.
The R88G-HPG11@ uses two set screws for the connecting section.
6. Mount the supplied rubber cap to complete the installation procedure.
(For the R88G-HPG11@, mount two screws with gaskets.)
