Vane Type Rotary Actuator
Series CRB2/CRBU2/CRB1
Vane Type Rotation: 90°, 180°, 270° All series can rotate up to 270°. The use of specially designed seals and stoppers now enables our compact vane type rotary actuators to rotate up to 270° (single vane type).
Direct mounting The body of rotary actuator can be mounted directly. ∗ Direct mounting is possible for size 10 to 30 rotary actuators with angle adjuster only.
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.
Direct mounting from 3 different directions is possible (CRBU2). Series CRBU2 can be mounted in 3 directions: axial, topported, and side-ported. In the axial direction, there are 3 mounting variations.

Body through holes
The use of bearings in all series (CRB2/ CRBU2/CRB1) to support thrust and radial loads, along with the implementation of an internal rubber bumper (except for size 10), improves reliability and durability.
Two different connecting port positions (side and axial) are available. The port position can be selected according to the application. (Only side ports are available for actuators with angle adjuster.)
Side-ported mounting
Low pressure operation
Body through holes
Special seal construction allows for a broader operating pressure range and makes operation in low pressure applications possible. Minimum operating pressure Size 10: 0.2MPa Sizes 15 to 100: 0.15MPa
Block (Unit) type construction
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.
Auto switch units and angle adjusters do not protrude beyond the outside diameter of the actuator body, and can be easily retrofitted to any actuator in the series.

Specific Product Precautions
Copper-free Use the standard vane type rotary actuators in all series to prevent any adverse effects to colour CRTs∗ due to copper ions or fluororesin.
Be sure to read before handling. Refer to pages 104 through 110 for safety instructions, actuator precautions, and auto switch precautions.

Caution 1. In case of a rotary actuator for a 90° or 180° application, the maximum angle will be limited by the rotation of the rotary actuator itself. Make sure to take this into consideration when ordering. In case of a rotary actuator for a 90° or 180° application, angle adjustment at the maximum angle of 90° or 180°, respectively, is not feasible. This is due to the fact that the rotation of the +4° rotary actuator is limited to 90° +4° 0 or 180° 0 , respectively. Therefore, for the single vane type, use a rotary actuator with a rotation angle of 270°, and for the double vane type, use a rotary actuator with a rotation of 100°. When operating a rotary actuator with a rotation of 90° or 180°, the rotation should be adjusted to within 85° and 175°, respectively, as a guide.
2. Connecting ports are side ports only. 3. The allowable kinetic energy is the same as the specifications of the rotary actuator by itself (i.e., without angle adjuster).

Specific Product Precautions
Caution 1. Since the maximum angle of the rotation adjustment range will be limited by the rotation of the rotary actuator itself, make sure to take this into consideration when ordering. Rotation of the rotary actuator 270° +40
Rotation adjustment range 0° to 230° (Sizes: 10, 40)∗ 0° to 240° (Sizes: 15, 20, 30)
180° +40
0° to 175°
90° +40
0° to 85°
∗ The maximum adjustment angle of the angle adjuster for size 10 and 40 is 230°.
2. Connecting ports are side ports only. 3. The allowable kinetic energy is the same as the specifications of the rotary actuator by itself (i.e., without angle adjuster). 4. Use a 100° rotary actuator if you desire to adjust the angle to 90° using a double vane type.

• Excellent reliability and durability The use of bearings to support thrust and radial loads improves reliability and durability. • The body of the rotary actuator can be mounted directly. • Two different port positions (side and axial) are available.
Caution Be sure to read before handling. Refer to pages 104 through 110 for safety instructions, actuator precautions, and auto switch precautions.

Built-in One-touch fittings facilitate the piping work and greatly reduce the installation space.
The double-seal construction of the actuator shaft section of these series to channel exhaust through the relief ports directly to the outside of a clean room environment allows operation of these cylinders in a class 100 clean room.

Rotation Adjustment Method
Other Operating Methods
Remove the resin cap in the illustrations below, slide the stopper block on the long groove and lock it into the appropriate position to adjust the rotation and rotation position. Protruding four chamfers for wrench on the output shaft that rotates allow manual operation and convenient positioning. (Refer to the rotation setting examples shown in the next page for details.)
Although one stopper block is mounted on each long groove for standard specifications as shown in the illustrations below, 2 stopper blocks can be mounted on one long groove. Angle adjustment range when 2 stopper blocks are mounted on a single long groove: Sizes: 10, 40 ................... 50° Sizes: 15, 20, 30 ............. 60°

by moving stopper block (A) and (B). (When mounting 2 stopper blocks on the other groove, the rotation range of the output shaft with single flat (key) can be set within 50° or 60° to right of port A and B which is opposite of what is shown in

When block (C) is locked and block (D) is moved counterclockwise, the shaft with single flat in Fig. 1-1 rotates from point zero to end of rotation . The maximum rotation range of the shaft with single flat is as follows: Sizes 10, 40: up to 230°; Sizes 15, 20, 30: up to 240° (Fig. 1-2 shows when the rotation is 0°.)

Air Consumption/Required Air Capacity Air Consumption Air consumption is the volume of air that is expended by the rotary actuator's reciprocal operation inside the actuator and in the piping between the actuator and the switching valve. It is required for selection of a compressor and for calculation of its running cost. ∗ The air consumption (QCR) required for one reciprocation of a single rotary actuator alone is shown in the table below, and can be used to simplify the calculation. Formulas
When selecting a compressor, it is necessary to choose one that has sufficient reserve for the total downstream air consumption of all pneumatic actuators. This is affected by factors such as leakage in piping, consumption by drain valves and pilot valves, and reduction of air volume due to temperature drops.
QCR: When the internal volume of a rotary actuator varies depending on the A and B ports, use formula (1).
