Product Description
SMC rotary actuator
[Features]
· Compact and lightweight
· Flexible mounting
Can be mounted from the top, bottom or sides
· Supports both front and side porting
· Improved allowable load
Uses a large roller bearing and large diameter output shaft

Rotation Direction and Rotation Angle
Image of swing direction and swing angle
- The shaft rotates clockwise when pressure is applied from port A, and counterclockwise when pressure is applied from port B.
- With the external stopper, the rotation end can be set within the range of the figure by adjusting the stopper bolt.
Basic Type
Swing direction and swing angle for 90° and 100°
Swing direction and swing angle for 180° and 190°
With external stopper
Swing direction and swing angle for 90°
Swing direction and swing angle for 180°
- * The figure shows the swing range of the single chamfered shaft.
- * The single chamfered position in the figure shows the counterclockwise end when the swing angle is 90° and 180°.
Notes
Adjusting the swing angle
For models with an external stopper, an angle adjustment screw that can adjust the swing angle is standard equipment.
The swing angle adjustment range with an external stopper is ±5° at each swing end. If the adjustment exceeds ±5°, the operation of the product may be impaired.
Size: Adjustment angle per rotation of angle adjustment screw
05・1 : 2.3°
Precautions for mounting speed controller / pipe fittings
Since the port uses M3 × 0.5, use the following series when connecting the speed controller and pipe fitting directly.
- Speed controller: AS12□1F / Elbow type, AS13□1F / Universal type
- Quick-connect fittings: Single-Action, Mini KQ2 Series
- Miniature pipe fittings: M3 Series
