∗ When performing control of cylinder output, do not create a restriction
circuit using a speed controller, etc. Pressure inside the cylinder will drop
and control will become impossible. Always control actuation by means of
pressure control.
Applications based on low friction specification
1) Operating resistance will vary with an offset load. Be sure to properly align
the rod axis with the load and direction of movement when connecting.
When an offset load is expected, provide a suitable mechanism such as a
floating joint.
2) Use clean air (atmospheric pressure dew point temperature -10°C or less).
Use of a series AM mist separator (filtration rating of 0.3µm or less), or
series AM + AMD (filtration rating of 0.01µm or less) is recommended.

Note 1) ISO 4414: Pneumatic fluid power -- Recommendations for the application of equipment to transmission and control
systems
Note 2) JIS B 8370: General Rules for Pneumatic Equipment
Warning
1. The compatibility of pneumatic equipment is the responsibility of the person
who designs the pneumatic system or decides its specifications.
Since the products specified here are used in various operating conditions, their compatibility for the
specific pneumatic system must be based on specifications or after analysis and/or tests to meet your
specific requirements.
2. Only trained personnel should operate pneumatically operated machinery and
equipment.
Compressed air can be dangerous if an operator is unfamiliar with it. Assembly, handling or repair of
pneumatic systems should be performed by trained and experienced operators.
3. Do not service machinery/equipment or attempt to remove components until
safety is confirmed.
1. Inspection and maintenance of machinery/equipment should only be performed after confirmation of
safe locked-out control positions.
2. When equipment is to be removed, confirm the safety process as mentioned above. Cut the supply
pressure for this equipment and exhaust all residual compressed air in the system.
3. Before machinery/equipment is restarted, take measures to prevent shooting-out of cylinder piston rod,
etc. (Bleed air into the system gradually to create back-pressure.)
4. Contact SMC if the product is to be used in any of the following conditions:
1. Conditions and environments beyond the given specifications, or if product is used outdoors.
2. Installation on equipment in conjunction with atomic energy, railway, air navigation, vehicles, medical
equipment, food and beverages, recreation equipment, emergency stop circuits, press applications, or
safety equipment.
3. An application which has the possibility of having negative effects on people, property, or animals,
requiring special safety analysis.

MQQ/MQM
Actuator Precautions 1
Series
Be sure to read before handling.
Design
Design
1. There is a danger of sudden action by air cylinders if
sliding parts of machinery are twisted and changes
in force occur.
9. Consider the action when operation is restarted after
an emergency stop or abnormal stop.
Warning
In such cases, human injury may occur; e.g., by catching hands
or feet in the machinery, or damage to the machinery itself may
occur. Therefore, the machine should be adjusted to operate
smoothly and designed to avoid such dangers.
Warning
Design the machinery so that human injury or equipment
damage will not occur upon restart of operation. When the
cylinder has to be reset at the starting position, install safe
manual control equipment.
2. A protective cover is recommended to minimize the
risk of human injury.
If a driven object and moving parts of a cylinder pose a danger
of human injury, design the structure to avoid contact with the
human body.
3. Securely tighten all stationary parts and connected
parts so that they will not become loose.
Particularly when a cylinder operates with high frequency or is
installed where there is a lot of vibration, ensure that all parts
remain secure.
4. A deceleration circuit or shock absorber, etc., may
be required.
Selection
Warning
1. Confirm the specifications.
The products advertised in this catalog are designed according
to use in industrial compressed air systems. If the products are
used in conditions where pressure, temperature, etc., are out
of specification, damage and/or malfunction may be caused.
Do not use in these conditions. (Refer to specifications.)
Consult SMC if you use a fluid other than compressed air.
2. Intermediate stops
When a driven object is operated at high speed or the load is
heavy, a cylinder's cushion will not be sufficient to absorb the
shock. Install a deceleration circuit to reduce the speed before
cushioning, or install an external shock absorber to relieve the
shock. In this case, the rigidity of the machinery should also be
examined.
When intermediate stopping of the cylinder piston is performed
by a 3 position closed center type directional control valve, it is
not possible to maintain the stop position for an extended time
due to the construction of the metal seal cylinder.
5. Consider the possibility that operating pressure may
drop due to a power outage, etc.
1. Operate the piston within a range such that collision
damage will not occur at the stroke end.
2. When controlling cylinder output, do not create a
restricting circuit by using a speed controller, etc.
Pressure inside the cylinder will drop and control
will become impossible. Be sure to control actuation
through pressure control.
When a cylinder is used in a clamping mechanism, there is a
danger of work pieces dropping if there is a decrease in
clamping force due to a drop in circuit pressure caused by a
power outage, etc. Therefore, safety equipment should be
installed to prevent damage to machinery and human injury.
Suspension mechanisms and lifting devices also require
consideration for drop prevention.
Caution
Mounting
6. Consider a possible loss of power source.
Measures should be taken to protect against human injury and
equipment damage in the event that there is a loss of power to
equipment controlled by pneumatics, electricity or hydraulics,
etc.
7. Design circuitry to prevent sudden lurching of driven
objects.
When a cylinder is driven by an exhaust center type directional
control valve or when starting up after residual pressure is
exhausted from the circuit, etc., the piston and its driven object
will lurch at high speed if pressure is applied to one side of the
cylinder because of the absence of air pressure inside the
cylinder. Therefore, equipment should be selected and circuits
designed to prevent sudden lurching, because there is a
danger of human injury and/or damage to equipment when this
occurs.
8. Consider emergency stops.
Design so that human injury and/or damage to machinery and
equipment will not be caused when machinery is stopped by a
safety device under abnormal conditions, such as a power
outage or a manual emergency stop.
Caution
1. Be certain to align the rod axis with the load and
direction of movement when connecting.
When not properly aligned twisting may occur in the rod and
tube, and this may cause abrasion or galling on the inside of
the tube, and the surface of the bushings and rod, etc.
2. When an external guide is used, connect the rod end
and the load in such a way that there is no
interference at any point within the stroke.
3. Do not scratch or gouge the cylinder tube or sliding
parts of the piston rod by striking or grasping them
with other objects.
Cylinder bores are manufactured to precise tolerances, so that
even a slight deformation may cause faulty operation.
Moreover, scratches or gouges, etc., in the sliding part of the
piston rod may cause malfunction.
4. Prevent the seizure of rotating parts.
Prevent the seizure of rotating parts (pins, etc.) by applying
grease.

5. Do not use equipment until you verify that it can
operate properly.
After mounting, repair or modification, etc., connect the air
supply and electric power, and then confirm proper mounting
by means of appropriate function and leak inspections.
6. Instruction manual
Mount and operate the product after thoroughly reading the
manual and understanding its contents.
Also, keep the manual where it can be referred to as needed.
Piping
1. 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 piping.
2. Wrapping of sealant tape
When screwing together pipes and fittings, etc., be certain that
chips from the pipe threads and sealant material do not get
inside the piping.
Also, when sealant tape is used, leave 1.5 to 2 thread ridges
exposed at the end of the threads.

Install air filters near valves on their upstream side. The
filtration degree should be 5µm or less. Furthermore, when
controlling for low speed or controlled output, use clean air
(atmospheric pressure dew point temperature of –10°C).
Installation of mist separator series AM (filtration degree 0.3µm
or less) or series AM + AMD (filtration degree 0.01µm or less)
is also recommended.
2. Install an after-cooler, air dryer or water separator,
etc.
Air that contains excessive drainage can cause malfunction of
valves and other pneumatic equipment. To prevent this, install
an after-cooler, air dryer or water separator, etc.
3. Use the product within the range of specifications
for fluid and ambient temperature.
Caution
Ex
1. Install air filters.
Take measures to prevent freezing when used at 5°C or less,
since moisture in circuits can freeze and this may cause
malfunction.
Refer to the "Air Cleaning Equipment" catalog for details on
compressed air quality.
Operating Environment
Warning
1. Do not use in environments where there is a danger
of corrosion.
Refer to the construction drawings regarding cylinder materials.
2. Do not use in dusty locations or where water, oil,
etc., will splash on the equipment.

Lubrication
Warning
1. Perform maintenance according to the procedures
indicated in the instruction manual.
Caution
1. Lubrication of non-lube type cylinder
Do not apply lubrication when controlling for low speed or
controlled output. If lubrication is applied, there may be
changes in operating resistance due to factors such as the
viscosity and surface tension of the oil. Also, use a metal seal
type when using solenoid valves for cylinder actuation. If a
rubber seal type is used, there may be an increase in
operating resistance due to grease sprayed from the main
valve.
Lubrication is also unnecessary for high speed actuation, but
in the event that lubrication is applied, use turbine oil class 1
(with no additives) ISO VG32. (Do not use spindle oil or
machine oil.)
If handled improperly, malfunction and damage of machinery
or equipment may occur.
2. Removal of equipment and supply/exhaust of
compressed air.
When equipment is removed, first check measures to prevent
dropping of driven objects and run-away of equipment, etc.
Then cut off the supply pressure and electric power, and
exhaust all compressed air from the system.
When machinery is restarted, confirm measures to prevent
lurching and proceed with caution.
Caution
1. Drain flushing
Air Supply
Warning
1. Use clean air.
Do not use compressed air containing chemicals, synthetic
oils containing organic solvents, salt or corrosive gases, etc.,
as it can cause damage or malfunction.

See pages 19 through 21 for safety instructions and actuator precautions.
Operation
Disassembly
1. When mounting, thoroughly flush out the connector
piping and be sure that dirt and chips, etc., do not
get inside the cylinder.
2. Install an air filter with a filtration degree of 5µm or
less on the air supply. Furthermore, when controlling
for low speed or controlled output, use clean air
(atmospheric pressure dew point temperature of
–10°C). Installation of a mist separator (filtration
degree 0.3µm or less) is also recommended.
3. Use a metal seal type when using solenoid valves for
cylinder actuation. If a rubber seal type is used,
there may be an increase in operating resistance
due to grease sprayed from the main valve.
4. Operate so that the load applied to the piston rod is
normally in the axial direction.
1. The component parts of the metal seal cylinder are
manufactured to precision tolerances, and therefore
cannot be disassembled.
Caution
Caution
In the event that a lateral load is unavoidable, do not exceed
the range of the allowable lateral load at the rod end (refer to
pages 23 and 24). (Use outside of the operating limits may
cause an adverse effect on the life of the unit through problems
such as looseness in the guide unit and a loss of precision.)
5. Take care not to scratch or gouge the sliding portion
of the rod. This may cause malfunction or shorten
the unit’s life.
6. When attaching a work piece to the end of the rod,
move the rod to the fully retracted position and use
the wrench flats at the end of the rod. Fasten the
work piece without applying a large amount of
torque to the rod.
7. Be certain to connect a load so that the rod axis is
aligned with the load and its direction of movement.
