Rotary Actua tor Vane Style Rotating angle:, 18, 27 All series can rotate up to 27. The use of specially designed seals and stoppers now enables our compact vane type rotary actuators to rotate up to 27. (Single vane type) irect mounting The body of rotary actuator can be mounted directly. Not possible to use direct mount type with units sized to. Screw x 3 Screw x Excellent reliability and durability Bearings are used in all series to support thrust and radial loads. The use of a rubber bumper (except size ) further improves reliability. Two different connecting port locations (side and axial) are available. The port location can be selected according to the application. (Types with various units sized to are body side face only.) Low pressure operation Special seal construction allows for a broader operating pressure range and makes operation in low pressure applications possible. Min. operating pressure :.2 MPa to :. MPa Unrestricted auto switch mounting position Since the switches can be moved anywhere along the circumference of rotary actuator, they can be mounted at the optimum position according to the rotary actuator's specifications. irect mounting from 3 different directions is possible (). Series can be mounted in 3 directions: axial, vertical, and lateral. In the axial direction, there are mounting variations. Axial Mounting Vertcal Mounting Body tapped Body through-hole Body throughhole Since it may not be necessary to use all the convenient mounting holes to mount the actuator from three directions at the same time, the remaining holes can be used for other purposes.

Although the outside dimensions of the double vane construction actuators are equivalent to those of the single vane construction type (except for size ). ouble vane construction can get twice the torque of the single vane style. CR Block (Unit) type construction For all series rotary actuator s single body, various units for body outside diameter integral type can be easily retrofit.
