Page 5: Rotary Actuators Precautions
Design / Selection Warning (1) Confirm the specifications. Products represented in this catalog are designed only for use in compressed air systems. Do not operate at pressures or temperatures, etc., beyond the range of specifications, as this can cause damage or malfunction. (Refer to the specifications.) We do not guarantee against any damage if the product is used outside of the specification range. - Page 6 (12) Select a speed within the product’s allowable energy value. If the kinetic energy of the load exceeds the allowable value, it could damage the product, and cause a hazard to humans, or damage the machinery and equipment. (13) Provide a shock absorber if the kinetic energy that is applied to the product exceeds the allowable value.
- Page 7 Design / Mounting Warning (1) Operation manual Install the product and operate it only after reading the operation manual carefully and understanding its contents. Also, keep the manual in a location where it can be referred to as necessary. (2) Ensure sufficient space for maintenance activities. When installing the products, allow access for maintenance.

- Page 9 Caution (1) Do not use organic solvent to wipe the area of the name plate that shows the model. It will erase what is indicated on the name plate. (2) Do not hit the output shaft by securing the body or hit the body by securing the output shaft.
- Page 10 Speed and Cushion Adjustment Warning (1) To make a speed adjustment, gradually adjust starting from the low speed end. If the speed adjustment is performed from the high speed end, it could damage the product. As a result, it could pose a hazard to humans and damage the machinery and equipment. For products with shock absorbers, when the shock absorber stops moving before reaching the stroke end by using a stopper mechanism with the objective of shortening tact time, be sure the shock absorber is stopped in a position where it has adequately absorbed the...
- Page 11 (3) Take measures to ensure air quality, such as by installing an aftercooler, air dryer, or water separator. Compressed air that contains a large amount of moisture can cause malfunction of pneumatic equipment such as rotary actuator. Therefore, take appropriate measures to ensure air quality, such as by providing an aftercooler, air dryer, or water separator.

Page 12: Auto Switches Precautions
Auto Switches Precautions Design / Selection Warning (1) Confirm the specifications. If the product is used with excess load applied or beyond the specification range, this may cause the product to break or malfunction. We do not guarantee against any damage if the product is used outside of the specification range. - Page 13 (3) Do not use a load that generates surge voltage. If a surge voltage is generated, discharge may be generated at the contact, possibly reducing the product life. <Reed> Use an auto switch with built-in contact protection circuit or use a contact protection box. <Solid state>...
- Page 14 (8) Use the rotary actuator and auto switch in proper combination. The auto switch is pre-adjusted to operate properly for an auto-switch-capable SMC rotary actuator. If the auto switch is mounted improperly, used for another brand of rotary actuator or used after changing the machine installation, the auto switch may not operate properly.
- Page 15 (4) Be certain to connect the load before power is applied. <2-wire type> If the power is turned ON when an auto switch is not connected to a load, the auto switch will be instantly damaged because of excess current (Short circuit). In addition, when using a commercially available checker, etc., to perform an acceptance inspection or check the operation of a 2-wire auto switch, be sure to confirm the wiring method of the checker beforehand and make sure to connect the terminal with a built-in load (IN, etc.)
- Page 16 (2) Do not use in an environment where the auto switch will be continually exposed to water. Although auto switches satisfy IEC standard IP67 construction, do not use auto switches in applications where they will be continually exposed to water splash or spray. This may cause improper insulation or malfunction.
- Page 17 Caution (1) Perform the following maintenance and inspection periodically in order to prevent possible danger due to unexpected auto switch malfunction. 1) Secure and tighten auto switch mounting screws. If screws become loose or the mounting position is dislocated, retighten them after readjusting the mounting position.

How to Mount Loads How to connect a load directly to a single flat shaft. To secure the load, select a bolt of an appropriate size from those listed in tables 3 and 4 by taking the shaft’s single flat bearing stress strength into consideration. Table 3 Directly Fixed with Bolts (Refer to Fig. -
Page 31: Adjusting The Rotating Angle
Warning Adjusting the rotating angle Do not apply a load when adjusting the rotating angle. For size 20, 30 and 40, the rotation range can be set as shown in Fig.11 and 12 by adjusting the adjustment bolt whilst supplying air to the opposite port. *A Box wrench may be required to adjust the angle depending on the usage environment. -
Page 32: Operating Environment
Warning Operating environment Do not use in environments where there is a danger of corrosion. Refer to "Internal Construction and Components" on pages 4 to 6 for materials used for the rotary actuator. Never use this product in dusty locations or where water, oil, etc., splash on the equipment. -
Page 33: Setting Of Rotation Time
5. Setting of Rotation Time Even if the torque - required by the load in the rotation movement is small, the shaft and/or internal parts could become damaged depending on the inertia of the load. Therefore, select an appropriate model for your application by taking the load’s moment of inertia, kinetic energy, and rotation time into consideration. - Page 34 (3) Moment of inertia of each style can be found with the calculation formula shown below. How to read Graph 1. Example 1) When there are constraints for the moment of inertia of load and rotation time. From “Graph 1”, to operate at the load moment of inertia 1 x 10–4 kg·m2 and at the rotation time setting of 0.3 / 90°, the model will be CRB□30.

Page 36: Eternal Stopper
External stopper If the kinetic energy - generated by the load exceeds the actuator’s threshold value, an external dampening function must be provided to absorb the energy. The figure below shows the correct installation of external stopper. As a rotary actuator itself has a slight angular error due to the construction, use an external stopper when accurate positioning is required. -
