Design / Selection
(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.
We do not guarantee against any damage if the product is used outside of the specification range.
(2)
If 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.
(3)
If 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.
(4)
Make 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.
(5)
There may be cases in which a speed reduction circuit or a shock absorber is required.
If the driven object moves at high speeds or is heavy, it will be unfeasible for only the rotary actuator cushion
to absorb the shock. Therefore, provide a speed-reduction circuit to reduce the rotary actuator speed before
the thrust is applied to the cushion, or an external shock absorber to dampen the shock. If these
countermeasures are taken, make sure to take the rigidity of the mechanical equipment into consideration.
(6)
Consider 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.
(7)
Consider the possibility of power source related malfunctions that could occur.
For equipment that relies on power sources such as compressed air, electricity, or hydraulic pressure, adopt
countermeasures to prevent the equipment from causing a hazard to humans or damage to the equipment in
the event of malfunction.
(8)
If a speed controller is provided in the exhaust restrictor, implement a safety design taking the residual
pressure into consideration.
If air pressure is applied to the air supply side without residual pressure in the exhaust side, the rotary actuator
will operate at abnormally high speeds, which could pose a hazard to humans and damage the machinery and
equipment.
(9)
Consider 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.
(10) Consider the action of the rotary actuator when restarting after an emergency stop.
Devise a safe design so 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.
(11) Do not use the product as a shock absorber.
If an abnormal pressure or air leakage occurs, the rotary actuator speed reduction capability could become
severely affected, which could pose a hazard to humans and damage the machinery and equipment.
