Cushioning capacity
While variable cushions are standard
equipment on all rodless cylinders, keep the
maximum mass and speed within the ranges
shown in the graph to the right. If load and
speed exceed the ranges, install an external
shock absorber, etc., to absorb the shock.
Cautions: 1. The maximum operating speed of
the rodless cylinders is 1500mm/s
[59.1in./sec.]. Consult us when
exceeding this.
2. The mass shown in the graph is the
total mass carried by the rodless
cylinder.
3. Adjust cushions according to the
piston speed and the mass, and
absorb the impacts effectively.

When the stroke is long and the load is large,
deflection might be caused on the cylinder
barrel. When support span:R exceeds the
value in the graph, it should be supported
by installing an adapter in the middle. U-type
and G-type adapters are available for 63
[2.480in.] and 80 [3.150in.].
Caution: If the support span exceeds 4000mm
[157.48in.] with 63 [2.480in.], or
5000mm [196.85in.] with 80 [3.150in.],
adapters must be installed in the middle
regardless of the load.

Mounting
1. While any mounting direction is allowed, we
recommend that the rodless cylinder be
installed so that it faces downward when
mounting in locations subject to dripping
water or oil, etc., or to large amounts of
dust.
2. Avoid any electric welding after mounting
the rodless cylinder. Current may flow into
the cylinder, generate sparks between the
inner seal band, outer seal band, and
cylinder barrel, and damage the seal band.
Intermediate stop control
Since for structural reasons external air
leakage is inevitable for the rodless cylinder,
use of all port block 3-position valves, etc., for
intermediate stop control could result in failure
to maintain the stopping position, and the
piston speed could not be controlled when
restarting. We recommend, therefore, double-
sided pressure control circuits that use
PAB-connection 3-position valves, etc. For
intermediate stopping control under constant
loads, such as vertical mountings, consult us.
Caution: Avoid applying strong shocks to the
cylinder barrel’s slit portion.

Assembling instructions General precautionsMaintenance
Sensor switch
The rodless cylinder is structurally incapable of
completely preventing air leakage to the
outside. Nevertheless, particles adhering to
the inner seal band are the most common
cause of initial-staged air leakages, and this
type of failure is easily remedied.
First, loosen the outer seal band setscrews,
remove the outer seal band, and apply approx.
0.1MPa [15psi.] of air pressure to the rodless
cylinder. Next, insert a cleaning tool inside the
cylinder barrel slit and then, while pressing
down the inner seal band and moving it along
the slit, use air to blow off the particles.

Assembling the piston mount
1. The sensor switch case is a magnetic
shield type, but avoid using it in places with
strong external magnetic field and keep it
away from strong power lines or currents.
2. Do not apply more than 98N [22lbf.] tensile
force on the lead wire.
3. Avoid use in ambient chemical atmospheres.
4. Consult us regarding application in
environments subject to dripping water or
oil.
5. The ON time of the sensor switch shortens
when the piston speed is fast and the
sensor switch is installed in the middle of
the stroke. Care should be taken because
the relay etc. might not be able to follow.
ON time [ms] (operation range mm [in.] /
piston speed mm/s [in./sec.]) 103
Handling precautions
Cautions: 1. Always use protective glasses.
2. When performing maintenance, use
the special cleaning tool. Use of a
screwdriver or other tool could
damage the inner seal band or
cylinder barrel.
3. If the above maintenance fails to stop
the air leakage, follow instructions in
the user’s manual to perform a
cylinder overhaul.
Always thoroughly blow off (use compressed
air) the tubing before connecting it to the
rodless cylinder. Entering chips, sealing tape,
rust, etc., generated during piping work could
result in air leaks or other defective operation.
Piping
Though it is possible to use without lubricating
oil when the cylinder speed is 500mm/s
[19.7in./sec.] or less, it is recommended to use
the following lubricating oils when using at a
speed of 500mm/s [19.7in./sec.] or more.

1. If using in locations subject to dripping
water, dripping oil, etc., or to large amounts

2. Do not engage in electric welding close to
the rodless cylinder. The welding spatters
could damage the outer seal band.
3. The product cannot be used when the
media or ambient atmosphere contains any
of the substances listed below.
Organic solvents, phosphate ester type
hydraulic oil, sulphur dioxide, chlorine gas,
or acids, etc.
Atmosphere
1. Use air for the media. For the use of any
other media, consult us.
2. Air used for the rodless cylinder should be
clean air that contains no deteriorated

(filtration of a minimum 40 µm) near the
rodless cylinder or valve to remove
collected liquid or dust. In addition, drain
the air filter periodically.

A long stroke of up to 5000mm [196.8in.] can be manufactured. It
can also be used to make driving equipment, which could not be
done by air cylinders in the past.
The magnet for the sensor switch is standard equipment. By
installing a sensor switch, the piston position can be easily

man-hours can be greatly reduced.
Upside down installation mountings have been put into a series.
By installing the piston yoke facing downwards, the seal band is
protected, thereby increasing its durability.
