5.3 External Dimensions
5.3.7 Servomotors with Gears
5-28
Note: 1. The values in parentheses are for Servomotors with Holding Brakes.
2. Gear dimensions are different from those of the
Σ
,
Σ
-II, and
Σ
-III Series.
3. The values for the shaft end are for a straight shaft with key and tap. If a key and tap are not necessary,
specify shaft end code 2 for the 8th digit.
Flange Output Face
Note: The geometric tolerance in parentheses is the value for LC = 40.

For models that have a batteryless absolute encoder, L is 8 mm greater than the given value. Refer to the follow-
ing section for the values for individual models.

For a Servomotor with a flange output that has square gear flange dimensions (
LC) of 40 mm,
we recommend that you design the Servomotor with the dimensions shown in the following figure
in order to secure a gap between the gear oil seal and the connecting parts on the load side.
