For 2,000-r/min Servomotors (400 W to 1 kW)
*1. D6 is the maximum diameter of the decelerator body between the flange side and Servomotor side.
(Refer to the Outline Drawing) The value is given only when the diameter is larger than the diameters of these two sides.
Take heed of this when you mount the decelerator to the machine.
*2. Indicates set bolt.
Note 1. The standard shaft type is a straight shaft.
2. A model with a key and tap is indicated with “J” at of the model number. (Example:
R88G-HPG32A052K0BJ)
3. The diameter of the motor shaft insertion hole is the same as the shaft diameter of the corresponding
Servomotor.
4. You cannot use this type of Decelerator for the Servomotor with key.
5. The dimensional drawings in this document are for showing main dimensions only, and they do not give
