Series CRB2 Screw x 3 Direct mounting The rotary actuator body can be mounted directly. Not possible for size 10 to 40 with unit(s). CRB2 The mounting position of the auto switch can be set freely. The switch can be fixed in the desired position in the circumferential direction. Connecting port location: Side ported or Axial ported The port location can be selected according to the application. Side ported (Size 10 to 40 with unit(s) are side ported only.) Axial ported Double vane type is standardized for 90 and 100 . The outside dimensions of the double vane type are equivalent to those of...

Working Principle/How to Mount Loads series CRB2 Vane Type 1. It consists of a shaft that is integrated with the vane that slides along the inner surface of the body, and a stopper. 2. The air that is supplied from port A pushes the vane, thus creating torque in the shaft. 3. The air in the exhaust chamber discharges via port B and rotates clockwise. 4. The vane stops as it comes in contact with the stopper. 5. Similarly, when air is supplied from port B, it rotates It consists of a shaft that is integrated with the 2 vanes that slide along the inner surface and 2 stoppers. The air that is...

Model Selection Selection Procedures Selection Example Operating conditions are as follows: • Tentative model • Mounting orientation • Load type Static load Resistance load Inertial load • The unit for the rotating angle is radian. "| I Calculation of Moment of Inertia Calculate the Inertial moment of load. • Loads are generated from multiple parts. The inertial moment of each load is calculated, and then totaled. 2 I Calculation of Required Torque Calculate the required torque for each load type and confirm that the values fall In the effective torque range. • When the resistance load is...

Model Selection 1-2 Calculation Example of Moment of Inertia 1 If the shaft is located at a desired point of the load: Center of gravity of load Example) 1. If the load is the thin rectangular plate: Obtain the center of gravity of load as li, a provisional shaft. 2. Obtain the actual moment of inertia I2 around the shaft, with the premise that the mass of the load itself is concentrated in the load's center of gravity point. 3. Obtain the actual moment of inertia I. L : Distance from the shaft to the center Calculation Example 2 If the load is divided into multiple loads: Example) 1. If...

Rotary Actuator Vane Type Single Vane Specifications Note 2) The upper numbers in this section in the table indicate the energy factor when the rubber 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 15. Double Vane Specifications Note 1) Make sure to operate within the speed regulation range. Exceeding the maximum speed (0.3 sec/90°) can cause the unit to stick or not operate. Note 3) Adjustment range in the table is for 100°....
