- Page 5 Limited warranty and Disclaimer / Compliance Requirements The product used is subject to the following “Limited warranty and Disclaimer” and “Compliance Requirements”. Read and accept them before using the product. Limited warranty and Disclaimer 1. The warranty period of the product is 1 year in service or 1.5 years after the product is delivered, whichever is first.
- Page 6 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.) Please contact SMC when using a fluid other than compressed air.
- Page 7 (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 and 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 8 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 Precautions when Converting Rotational Motion to Linear Motion When using a link mechanism, etc., to convert rotational motion to linear motion, and determining the operation end using the stopper on the linear motion end (see below), a small value for θ at the operation end may result in the torque of the rotary actuator causing excessive radial load to act on the output axle, and equipment breakage may occur.
- Page 10 Piping Caution (1) Refer to the Fittings and Tubing Precautions (Best Pneumatics No.6) for handling one touch fittings. (2) Preparation before piping Before piping is connected, it should be thoroughly blown out with air (flushing) or washed to remove chips, cutting oil and other debris from inside the pipe.
- Page 11 Air Supply Warning (1) Type of fluids Please consult with SMC when using the product in applications other than compressed air. (2) When there is a large amount of moisture Compressed air containing a large amount of moisture can cause malfunction of pneumatic equipment. An air dryer or water separator should be installed upstream from filters.
- Page 12 Maintenance Warning (1) Perform maintenance inspection according to the procedures indicated in the operation manual. If handled improperly, malfunction and damage of machinery or equipment may occur. (2) Maintenance work If handled improperly, compressed air can be dangerous. Assembly, handling, repair and element replacement of pneumatic systems should be performed by a knowledgeable and experienced person.
- Page 13 Auto Switches Precautions Design / Selection Warning (1) Confirm the specifications. Read the specifications carefully and use this product appropriately. The product may be damaged or malfunction if it is used outside the range of specifications of current load, voltage, temperature or impact. We do not guarantee against any damage if the product is used outside of the specification range.
- Page 14 (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. If driving a load such as a relay that generates a surge voltage. <Reed>...
- Page 15 Mounting / Adjustment Caution (1) Do not drop or bump. Do not drop, bump or apply excessive impacts (300m/s or more for reed auto switches and 1000m/s or more for solid state auto switches) while handling. Although the body of the auto switch may not be damaged, the inside of the auto switch could be damaged and cause malfunction.
- Page 16 (6) Avoid incorrect wiring. <Reed> A 24 VDC auto switch with indicator light has polarity. The brown lead wire or terminal No.1 is (+), and the blue lead wire or terminal No.2 is (-). 1) If connections are reversed, the auto switch will operate, however, the LED will not light up. Also, take note that a current greater than that specified will damage the LED and it will no longer operate.
- Page 17 (3) Do not use in an environment with oil or chemicals. Please consult with SMC if auto switches will be used in an environment with coolant, cleaning solvent, various oils or chemicals. If auto switches are used under these conditions for even a short time, they may be adversely affected by improper insulation, malfunction due to swelling of the potting resin, or hardening of the lead wires.

Page 30: Setting Of Rotation Time
4. 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 31 (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.

Table 1 Unit (J) Model Allowable kinetic energy CRB10 0.00015 0.001 CRB15 0.003 CRB20 0.02 CRB30 CRB40 0.04 Since the rotary actuator reaches the rotation end in the middle of acceleration, terminal acceleration "ω"... - Page 33 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.

Page 34: Maintenance And Inspection
5. Maintenance and Inspection ［Precautions］ a. Disassembling the product will void SMC’s warranty. If disassembly is really necessary it is recommended to fully understand the internal construction before disassembling the products. b. Do not damage the seals when reassembling the product. Be sure to add grease to all the seals and sliding surfaces of the bodies and vane shaft. - Page 35 Standard Type (For CRB20, 30, 40) 90° specification 180° specification Be sure to install an air filter to clean the supply air. ● Do not disassemble the actuator. When disassembling it for an unavoidable reason, follow the ● procedures below, and prevent dust and/or foreign matter from entering the product. (As operation failure is caused by an increase in the internal leakage in most of the cases, the speed controller needs to be readjusted.
