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/min. 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: Transfer speed of 15m/min., Mass of transferred object of 60kg, Friction coefficient μ= 0.1,

Lever type (Lever type with lock mechanism).

Find the intersection if the speed if 15m/min. 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 cylinder. 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

①Align the center of the pallet and the cylinder when mounting.

②Make 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 filter, 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 form 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 from the direction of the lever side, mounting

holes must be machined in accordance with recommended hole diameters 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. Prior 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)

①Remove the rod cover mounting screws (M4 x 2 pcs.) that hold the rod cover to the cylinder tube.

②Adjust the rod cover to the desired position. Direction can be adjusted by 90 degrees.

③Apply 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)

④Make sure that the cylinder operates smoothly.

[ Changing method of the ø16 to 50 bore piston rod direction ](Fig. 6)

①Loosen the hexagon socket head set screws (M3 x 2 pcs.) that hold the non-rotating guide in place.

②Adjust 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.

③Apply 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 flats 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.

④Make sure that the cylinder operates smoothly.

(Cylinder is set for maximum absorbed energy at the time of shipment)

[Adjustment method] (See Fig. 7)

①Loosen the set screw holding adjustment bolt in place (M4).

②Turn the adjustment bolt so that the impact is reduced.

③Tighten set screw to lock adjustment bolt in place.

9. Handling Precautions

Caution

①Do not use oil to the piston rod sliding part.

Retracting failure of the cylinder may occur.

②Protect the shock absorber from water, cutting oil and dust.

Leaving shock absorber unprotected may result in oil leakage and/or general operation failure.

③Do not scratch or dent the sliding parts of the piston.

The piston rod has not been hardened. If there is a danger of a pallet 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.

④Do 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.

⑤Do 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.

⑥Do 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.

⑦In 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.

⑧Please 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 periodically the levels of grease present, and apply additional grease

as necessary. (See Fig. 10)
