- 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. These actions could cause the table to bend or damage the bearing.
- Page 10 Lubrication Warning 1. This product should be used without lubrication. Although it will operate even if it is lubricated, it could lead to sticking or slipping. Air Supply Warning 1. Type of fluids Use 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.
- Page 11 Maintenance Warning Perform maintenance inspection according to the procedures indicated in the operation manual. If handled improperly, malfunction and damage of machinery or equipment may occur. 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 12 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 4. Take precautions when multiple rotary actuator are used close together. When multiple auto switch rotary actuator are used in close proximity, magnetic field interference may cause the auto switches to malfunction. Maintain a minimum separation of 40mm between rotary actuator.
- Page 14 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 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 15 beforehand and make sure to connect the terminal with a built-in load (IN, etc.) to the 0 V terminal. (Do not connect the power supply terminal and the ground terminal directly when in a non-load state.) 5. Do not allow short-circuit of loads. <Reed>...
- Page 16 5. Do not use in an environment where there is excessive impact shock. <Reed> When excessive impact (300m/s or more) is applied to a reed auto switch during operation, the contacts will malfunction and generate or cut off a signal momentarily (1ms or less). If further excessive impact is applied, the reed auto switch may break.
- Page 17 Maintenance Warning Removal of equipment, and supply/exhaust of compressed air. Before any machinery or equipment is removed, first ensure that the appropriate measures are in place to prevent workpieces from dropping, run-away equipment, etc. Then, cut off the electric power and reduce the pressure in the system to zero.

4. Mounting Caution 4-1. Air Supply (1) The air supplied to the rotary actuator shall be filtered by an SMC air filter and regulated to the specified set pressure by an SMC AR series regulator. (2) This is a non-lube type actuator. Never supply lubricant oil. (3) If lubricant is supplied to the actuator, the grease inside the actuator will be washed away, and this may cause operation failure. -

Warning 4-3．Shaft Load Limit (1) Although static loads shown in Table 2 are allowable, avoid applying load directly to the shaft. Table 2 Allowable Shaft Load Unit: N Load direction Model CRB1BW50 CRB1BW63 CRB1BW80 CRB1BW100 Note) Application point of force “Fr” is at the center of longitudinal dimension of the key. (2) For better operating conditions it is recommended to use the method shown in the figure below to avoid applying direct load to the shaft. -
Page 24: Operating Environment
Warning 4-5．Operating Environment Do not use in environments where there is a danger of corrosion. Refer to "Internal Construction and Components" on pages 19 for materials used for the rotary actuator. Never use this product in dusty locations or where water, oil, etc., splash on the equipment. 4-6．Direct Mounting of Body For the case when the main unit of the actuator is used as flange L dimension when the unit is used as a flange is shown in the table below. -
Page 25: 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 26 (3) Moment of inertia of each style can be found with the calculation formula shown below. How to read Graph 1 Example 1. When CRB1BW50 is used under conditions of moment of inertia of a load of 1.4x10 ⁵kg-m rotation time of 0.85 seconds to move 90 degrees; Since the intersection of 1.4 x 10 kg-m on the vertical axis and 0.85 seconds on the...

Page 28: External Stopper
5-3. 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 29: Maintenance And Inspection
6. Maintenance and Inspection ● 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. - Page 30 <Caution> 1. Products will be out of SMC's warranty once they are disassembled. Fully understand the internal construction before disassembling the products. 2. 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. 3.
