Rotary Actuator Vane Type Standard Type Free Mount Type Many combinations available! Standard type/Series CRB2 ¡Piping ports are located on the flat surface. Fittings can be secured firmly, piping is also improved. Flat surface ¡Many variations of shaft-end shape (6 types) Piping port Shaft-end shape With angle adjuster unit With auto switch unit With angle adjuster unit With auto switch unit Possible to adjust the angle as desired Rotating angle Rotating angle adjustment range 270° 90° Auto switch unit Angle adjuster unit Free mount type/Series CRBU2 is added. ¡12% weight reduction ¡Possible to move the plate mounting position as desired ¡Many mounting variations Vertical mounting Lateral mounting With angle adjuster unit With auto switch unit With angle adjuster unit With auto switch unit Rotating angle: 90°, 180°, 270° All series can rotate up to 270°. Interchangeable mounting pitch with the existing model The use of specially designed seals and stoppers now enables our compact vane type rotary actuators to rotate up to 270°. (Single vane type) Mounting pitches A to C shown on the right and D mounting hole diameters are interchangeable with the existing model. D: Height is reduced compared to the existing model.

Rotary Actuator Vane Type Single Vane Specifications Flange Assembly Part No. (For details, refer to page 12.) Model Note 1) ake sure to operate within the speed regulation range. Exceeding the maximum speed M (0.3 sec/90°) can cause the unit to stick or not operate. Note 2) he upper numbers in this section in the table indicate the energy factor when the rubber T bumper is used (at the end of the rotation), and the lower numbers indicate the energy factor when the rubber bumper is not used. Note 3) Adjustment range in the table is for 270°. For 90° and 180°, refer to page 14. (For details,...
