Select reducers by Servo Motor mounting dimensions

This selection tool enables you to search model number of a reducer attachable to your motor based on its mounting dimensions.
The Performance gaps between the motor and reducer are not considered, so please check each catalog for performance matching.

Note

• We can NOT apply this tool to motors with optional specification such as “with oil seals”. Please make sure whether your motor can be attachable to our reducers on “Detailed Dimensions of Input Shaft and Flange Shapes”.
• This tool does not determine whether the size of your motor flange matches input side of the reducer.
• This tool targets motors with straight shaft. If your motor has a key, it can be removed and attached to the reducer.
• We assume h6 on motor shaft and h7 on motor flange as Dimensional Tolerance of fitting part.

Please enter dimension of each point.

e.g.	F(Maximum value)	2.5+0.3＝2.8
	Gmax	24+0.5＝24.5
	Gmin	24-0.5＝23.5
