3. Operating air
The air supplied to the cylinder should be filtered by SMC AF series air filter and regulated to the
specified set pressure by SMC AR series regulator.
4. Speed adjustment
①When the piston speed has to be adjusted, install an SMC AS series speed controller near the air
inlet port and adjust it to obtain the specified speed.
②There are two ways to adjust the speed by using speed controller. One is by restricting the air
supplied to the cylinder. The other is by restricting the air exhausted from the cylinder.
Supply air is restricted for single acting cylinder, and exhaust air is restricted for double acting cylinder.
5. Directional control
To switch the operating direction of the cylinder, mount an applicable solenoid valve selected from
SMC's range of solenoid valves. Generally, double acting cylinder is switched by 4 way solenoid valve.
Single acting type is switched by 3 way solenoid valve.

6. Selection
6-1 Selection
Select the appropriate cylinder based on mass of transferred object and transfer speed (Fig.1).
Example 1: For roller type with transfer speed of 15m/min. and the mass of transferred object of 30kg.
Find the intersection if the speed if 15m/m in. on the horizontal axis and the mass of 30kg on
the vertical axis in graph, and select RSQ□40-□□RZ that falls in the cylinder operating range.
Example 2: Transf er s peed of 15m/min., Mass of trans f err ed obj ect of 60kg, Friction coefficient μ= 0.1,
Lever type (Lever type with lock mechanism).
Find the intersection if the speed if 15m/m in. on the horizontal axis and the mass of 60kg on
the vertical axis in graph, and select RSQ□40-□□DZ that falls in the cylinder operating range.
6-2 Precautions on Selection
Use for stopping the pallet on the conveyor. For stopping the load directly mounted to the cylinder, the
cylinder pushing force acts as lateral load. Please consult SMC in this case.
6-3.Lateral load and operating pressure
The larger the lateral load, the higher the operating pressure required for the stopper c ylinder. Set the
operating pressure using the Fig.2. as a guide.

7. Installation
7-1. Mounting bracket
Through hole type and both ends tapped style are available.
7-2 Mounting
① Align the center of the pallet and the cylinder when mounting.
② Make sure to flush inside the piping with air before piping to remove foreign matter. Filter removes foreign
matter such as dust and scaling inside the piping before the fil ter, but not after the filter. Foreign matter
after the filter directly enters the solenoid valve and cylinder, reducing the product life.
In order to prevent rotational torque from acting upon the cylinder rod, mount it so that the contacting
surfaces of the pallet and cylinder are parallel to one another.
③When the product is installed on a machine on site, the debris from drilled mounting holes can get in the
supply port of the product. Take sufficient care to prevent this.
④Inner diameter of cylinder tube is made with precise clearance. Do not let objects drop onto or deform the
inner parts by applying force during mounting. Otherwise, malfunction may result.
⑤Shorten the length of piping. If the cylinder piping is too long, the volume of vapor generated by the adiabatic
expansion volume in the piping will become larger than that in the cylinder, and it cannot be exhausted to the
air and remains in the piping. With repeated operation, this vapor will acuumulate and f orm water drops. This
will wash away the grease inside the product, causing lubrication to deteriorate, which can wear the seals
and cause air leakage and increased friction resistance, resulting in operation failure. Take the following
measures to prevent air leakage and malfunction.
(1)Make the piping tube between the solenoid valve and cylinder as short as possible to ensure that the
vapor generated will be exhausted into atmosphere.
Refer to Best Pneumatics2-1 P.1904 Technical
Data 4: Condensation.
(2) Release the exhaust pressure directly into the atmosphere by installing a speed exhaust controller
ASV or quick exhaust valve to the cylinder.
(3) Set the piping port downwards so that moisture inside the piping does not go back to cylinder easily.
⑥When the lever type with a built-in shock absorber is installed f rom the direction of the lever side, mounting
holes must be machined in accordance with recommended hole di ameters in Table 1. When it is installed
from the direction of the lever side of the stopper cylinder (Fig. 3), note that the lever's outer diameter is larger
than the rod cover boss diameter.

7-3. Change of the piston rod direction
For roller type and lever type, feed the pallet from the direction shown in Fig.4. P rior to changing the piston
rod direction, default factory settings require pallet to feed toward piping port side of cylinder.
[ Changing method of the ø12 bore piston rod direction ](Fig.5)
① Remove the rod cover mounting screws (M4 x 2 pcs.) that hold the rod cover to the cylinder tube.
② Adjust the rod cover to the desired position. Direction can be adjusted by 90 degrees.
③ Apply glue for screw, to the rod cover mounting screws.
Insert and tighten the rod cover mounting screws (2 pcs) to secure the rod cover to the cylinder tube.
Tightening torque is 1.5N・m
±10(%). (Tool： Hexagon wrench: Width across flats 3mm)
④ Make sure that the cylinder operates smoothly.
[ Changing method of the ø16 to 50 bore piston rod direction ](Fig. 6)
① Loosen the hexagon socket head set screws (M3 x 2 pcs.) that hold the non-rotating guide in place.
② Adjust the piston rod to the desired position.
Note: In order to prevent rotational torque from acting upon the piston rod, mount it so that the contacting
surfaces of the pallet and cylinder are parallel to one another.
③ Apply glue for screw, to hexagon socket head set screws. Insert and tighten two hexagon
socket head set screws to hold the non-rotating guide in place. Tightening torque is 0.63N・m
±10(%).
(Tool： Hexagon wrench: Width across f lats 1.5mm)
Note: Non-rotating guide is fixed by two hexagon socket head set screws. If one of the set screws is
tightened too much, the non-rotating guide may make contact with the piston rod, causing operation failure.
Therefore, tighten the hexagon socket head set screws in turn to make sure that the non-rotating guide
does not make contact with the piston rod.
④ Make sure that the cylinder operates smoothly.

9. Handling Precautions
Caution
① Do not use oil to the piston rod sliding part.
Retracting failure of the cylinder may occur.
② Protect the shock absorber from water, cutting oil and dust.
Leaving shock absorber unprotected may result in oil leakage and/or general operation failure.
③ Do not scratch or dent the sliding parts of the piston.
The piston rod has not been hardened. If there is a danger of a pal let scratching or nicking the piston rod due to
sharp edges, etc., the pallet should not be used. Damage to the piston rod may lead to improper operation.
④ Do not get your hands caught during cylinder operation.
Since the lever section moves up and down when the cylinder is in operation, take sufficient care to avoid getting
your hands caught between the rod cover and the lever holder.
⑤ Do not apply pressure from the head side of a single acting cylinder.
If air is supplied from the head side of a single acting cylinder, blow-by of the air will occur.
⑥ Do not allow a pallet to collide with the cylinder when the lever is upright.
In case of a lever with built-in shock absorber type, do not collide the next pallet against the first one while the
lever is standing erect. Otherwise, all energy will be applied to the cylinder body.
⑦ In the case of the model with locking mechanism, do not apply an external force from the opposite side when the
lever is locked.
When moving pallets during conveyor adjustment, first lower the cylinder.
⑧ Please do not remove the grease applied to Pin B and the lock mechanism bracket on the end lever. If the
cylinder is operated without grease, the locking and/or unlocking process may malfunction due to excessive wear
on Pin B and the rod cover. Please check periodical ly the levels of grease present, and apply additional grease
as necessary. (See Fig. 10)

10-2. Replacement procedure of shock absorber
① Loosen the hexagon socket head set screw (M3) at the piston rod by approximately one turn, and push
down the lever. (See Fig. 11)
Tool： Hexagon wrench: Width across flats 1.5mm
② While pushing down the lever, remove the shock absorber and replace it with a new shock absorber.
Tighten the hexagon socket head set screw (M3 x 0.5) of the piston rod. (See Fig. 12)
Stop tightening around 1/4 turn after the set screw comes into contact with the shock absorber.
If the hexagon socket head set screw is tightened too much, operation failure of the shock absorber can
result.
Tightening torque: 0.29N・m
