Design

①If the operation involves load fluctuations, ascending/descending movements, or changes in

friction resistance, make sure to provide safety measures.

Failure to provide such measures could accelerate the movement, which may be hazardous to humans,

machinery, and other equipment.

②If there is a chance that the product will pose a hazard to humans, install a protective cover.

If the moving portion of the product will pose a hazard to humans or will damage machinery or

equipment, provide a construction that prevents direct contact with those areas.

③Make sure that the secured portions will not loosen.

Be sure to adopt a reliable connecting method if the rotary table is used very frequently or if it is used in

a location that is exposed to a large amount of vibrations.

④Consider the possibility of a reduction in the circuit air pressure caused by a power failure.

When an actuator is used as clamping mechanism, there is a danger of workpiece dropping if there is a

decrease in clamping force, due to a drop in circuit pressure caused by a power failure. Therefore,

safety equipment should be installed to prevent damage to machinery and bodily injury.

⑤Consider the possibility of power source related malfunctions that could occur.

For the equipment that rely on power sources such as compressed air, electricity, or hydraulic pressure,

adopt a countermeasure to prevent the equipment from causing a hazard to humans or damage to the

equipment in the event of malfunction.

⑥Consider the behavior of the rotary actuator in the event of an emergency stop.

Devise a safe system so that if a person engages the emergency stop, or if a safety device is tripped

during a system malfunction such as a power failure, the movement of the rotary actuator will not cause

a hazard to humans or damage the equipment.

⑦Consider the action of the rotary actuator when restarting after an emergency stop.

Devise a safe design to that the restarting of the rotary actuator will not pose a hazard to humans

or damage the equipment. Install manually controlled equipment for safety when the actuator

has to be reset to the starting position.

⑧Do not use the product as a shock absorber.

If an abnormal pressure or air leakage occurs, the rotary actuator’s speed reduction capability could

become severely effected, which could pose a hazard to humans and damage the machinery and

equipment.

Selection

①Confirm the specifications

Rotary actuator is designed only for use in industry 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.

We do not guarantee against any damage if the product is used outside of the specification range.

②Select a speed within the product’s allowable energy value.

If the product’s 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.

③Provide a shock absorber if the kinetic energy that is applied to the product exceeds the

allowable value.

If the product’s kinetic energy exceeds the allowable value, it could damage the product, and cause a

hazard to humans and damage the machinery and equipment.

④Do not stop or hold the product at midpoint by keeping air pressure in the product.

For a product lacking an external stopping mechanism, if the directional control valve is closed to keep

the air pressure in the product, in an attempt to stop the product at midpoint, it might not be possible to

maintain that stopped position due to an air leakage. As a result, it could pose a hazard to humans and

damage the machinery and/or equipment.

⑤Do not use two or more rotary actuators with the aim of synchronized movement.

One of the actuators may bear the load of operation, making synchronized movement impossible, and

possibly leading to deformation of the equipment.

⑥Do not use in a location where adverse effect could be occurred by the oozing of the lubricant to

the exterior.

The lubricant coating the interior of the product may leak to the outside of the product from the portion of

the connection of the rotary shaft, body cover, etc.

①Do not use below the speed adjustment range specified for the product.

If the product is used below the specified speed adjustment range, it could cause the product to stick,

slip, or the movement to stop.

②Do not apply an external torque to the product that exceeds the rated output.

If an external force that exceeds the product’s rated output is applied to the product, it could damage the

product.

③If it is necessary to provide repeatability of the rotation angle, directly stop the load externally.

Even with a product that is equipped with an angle adjuster, there are times in which the initial rotation

angle could change.

④Do not use under hydraulic pressure.

The product will be damaged if it is used by applying hydraulic pressure.

⑤Do not use in places where there are many temperature fluctuations. When using in lower

temperature applications, use caution so that frost does not occur inside the cylinder or the

piston rod.

Operation may be unstable.

⑥Adjust the speed control in the environment in which it will be used in.

Speed adjustment may be changed if the environment is different.

Mounting

①Ensure sufficient space for maintenance activities.

When installing the products, allow access for maintenance.

②Before adjusting the angle by supplying air pressure, take appropriate measures to prevent the

equipment from rotating unnecessarily.

When an adjustment is performed under air pressure, the equipment could rotate and fall during the

adjustment, depending on the mounted placement of the equipment. As a result, it could pose a hazard

to humans and damage the machinery and equipment.

③Do not loosen the angle adjustment screw beyond the allowable adjustment range.

The angle adjustment screw could fall out if it is loosened beyond its allowable adjustment range and

cause a hazard to humans and damage to machinery and equipment.

④Do not place a magnetic object near the product.

The auto switch is a magnetic sensing type. If a magnetic object is placed close to it, the rotary actuator

could operate suddenly, which could pose a hazard to humans and damage the machinery and

equipment.

⑤Do not perform additional machining to the product.

Additional machining to the product can result in insufficient strength and cause damage to the product.

This can lead to possible human injury and damage to the surrounding equipment.

⑥Do not enlarge the fixed throttle by modifying the pipe connectors.

If the hole diameter is enlarged, the product’s rotation speed will increase, causing the shock force to

increase and damage to the product. As a result, it could pose a hazard to humans and damage the

machinery and equipment.

⑦If shaft couplings are used, use those with angular freedom.

If shaft couplings that lack angular freedom are used, they could scrape due to eccentricity, leading to

equipment malfunction and product damage. As a result, it could pose a hazard to humans and damage

the machinery and equipment.

⑧Place an external stopper in a position that is away from the rotating shaft.

If the stopper is placed near the rotating shaft, the torque that is generated by the product itself will

cause the reaction force which is directed to the stopper to be redirected and applied to the rotating

shaft. This will lead to the breakage of the rotating shaft and bearing.As a result, it could pose a hazard

to humans and damage the machinery and equipment.

Backlash of the Single Rack Pinion Type CRA1 Series

There is a backlash of within 1°at the rotation end of the CRA1 series. It is necessary to decide the

position of the external stopper when precise rotation is required.

⑨Do not use springs, etc., to add force in the rotational movement direction.

When rotational force from an external spring, etc., acts and generates negative pressure on the

product’s interior, breakage of the internal seal or acceleration of abrasion may occur.

①Do 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.

②Do not hit the rotating shaft by securing the body or hit the body by securing the rotating shaft.

These actions could cause the shaft to bend or damage the bearing. When a load must be coupled to

the rotating shaft, secure the rotating shaft.

③Do not place your foot directly on the shaft or on the equipment that is coupled to the shaft.

Placing one’s weight directly onto the rotating shaft could cause the rotating shaft or the bearing to

become damaged.

④If a product is equipped with an angle adjustment function, use it within the specified adjustment

range.

If the product is used outside the specified adjustment range, it could lead to equipment malfunction or

product damage.

Air Supply

①Use clean air.

Do not use compressed air that contains chemicals, synthetic oils including organic solvents, salt or

corrosive gases, etc., as it can cause damage or malfunction.

①When extremely dry air is used as the fluid, degradation of the lubrication properties inside the

equipment may occur, resulting in reduced reliability(or reduced service life) of the equipment.

Please consult with SMC.

②Install an air filter.

Install an air filter upstream near the valve. Select an air filter with a filtration size of 5 μm or smaller.

③Take measures to ensure air quality, such as by installing an aftercooler, air dryer, or water

separator.

Compressed air that contains a large amount of drainage can cause malfunction of pneumatic

equipment such as rotary actuators. Therefore, take appropriate measures to ensure air quality, such as

by providing an aftercooler, air dryer, or water separator.

④Ensure that the fluid and ambient temperature are within the specified range.

If the fluid temperature is 5°or less, the moisture in the circuit could freeze, causing damage to the

seals and equipment malfunction. Therefore, take appropriate measures to prevent freezing.

For compressed air quality, refer to Best Pneumatics No. 5.

Operating Environment

①Do not use in an atmosphere having corrosive gases, or where there is direct contact with this.

②Do not use in dusty locations or where water or oil, etc., splash on the equipment.

③Do not use in a place subject to heavy vibration and/or shock.

Speed Adjustment

①To 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.

could lead to sticking or slipping.

Maintenance and Inspection

①During a maintenance inspection, do not disassemble the equipment with electrical power

or an air supply applied.

②After the product has been disassembled for inspection, make sure to perform the appropriate

functionality inspection.

The product specifications cannot be met unless a functionality inspection is performed.

①For lubrication, use the designated grease for each specific product.

The use of a non-designated lubricant could damage the seals.

Attention of auto switch

Design / Selection

①Confirm the specifications.

Read the specifications carefully and use this product appropriately. The product may be damaged

or malfunction if it is used outside the specification range for current load, voltage, temperature or

impact.

①Take precautions when multiple actuators are used close together.

②Pay attention to the length of time that a switch is ON at an intermediate stroke position.

When an auto switch is placed at an intermediate position of the stroke and a load is driven at the time

the piston passes, the auto switch will operate, but if the speed is too great the operating time will be

shortened and the load may not operate properly.

The maximum detectable piston speed is:

V(mm/s)= ×1000

③Keep wiring as short as possible.

<Reed switch>

As the length of the wiring to a load gets longer, the rush current at switching ON becomes greater, and

this may shorten the product’s life. (The switch will stay ON all the time.)

1) Use a contact protection box when the wire length is 5 m or longer.

2) Even if an auto switch has a built-in contact protection circuit, when the wiring is more than 30 m long,

it is not able to adequately absorb the rush current and its life may be reduced.

It is again necessary to connect a contact protection box in order to extend its life. Please consult with

SMC in this case.

<Solid state switch>

3) Although wire length should not affect switch function, use a wire 100 m or shorter.

④Pay attention to the internal voltage drop of the auto switch.

<Reed switch>

1) Auto switch with an indicator light (Except D-A96 ,A96V)

●If auto switches are connected in series as shown below, take note that there will be a large voltage

drop because of internal resistance in the light emitting diodes. (Refer to the internal voltage drop in

the auto switch specifications.)

[The voltage drop will be “n” times larger when “n” auto switches are connected.]

Even though an auto switch operates normally, the load may not operate.

Load

●In the same way, when operating under a specified voltage, although an auto switch may operate

normally, the load may not operate. Therefore, the formula below should be satisfied after confirming

the minimum operating voltage of the load.

Supply Internal voltage Minimum operating

voltage drop of auto switch voltage of load

2) If the internal resistance of a light emitting diode causes a problem, select an auto switch without an

indicator for right (MODEL D-A90 , A90V)

<Solid state switch / 2-wire type>

3) Generally, the internal voltage drop will be greater with a 2 wire solid state auto switch than with a

reed auto switch. Take the same precautions as in 1).

Also, take note that a 12VDC relay is not applicable.
