The rodless cylinder presented in this manual can operate the load directly mounted on it without other
axes in a range of allowable mounted load, moment and stroke if it is equipped with the switch rail.
(Table1,2) (P8,9) However, without the switch rail, the load needs to be guided by other axes (LM guide
etc.) to prevent rotation of external slider and direct application of the load over the allowable range.
1-1) Installation of cylinder body
Before installation of cylinder body, be sure to fix end covers by bolts (to realize support at both ends).
(Fig. 1)
Also, do not use the cylinder with fixed at external slider to avoid excessive moment applied to
bearing of the cylinder.
Wrong example Correct example
Fig. 1 Installation of cylinder body
1-2-1) Installation of cylinder body
There are two ways to install the cylinder body as shown on Fig. 2-1 and 2-2. For each mounting
face and place, tighten the bolt on the top and bottom faces properly to make no looseness.

1-2) Installation of external slider and load
Same as installation of the cylinder body, there are two ways to install the external slider and load in
a range of allowable mounted load, moment and stroke.
(Ⅰ)With other axes combined
(Ⅱ)Without other axes combined
(Switch rail is used as non-rotation device.)
(Ⅰ)With other axes combined
Consider the following two points for mounting of external slider and load.
Ⅰ-a) The cylinder is deflected by self-weight as shown on Fig. 3-1. This means longer stroke produces
larger displacement of alignment.

Ⅰ-b) The misalignment between cylinder body and guide (orbit) may be caused depending on machining
accuracy of the space for mounting. Therefore, the installation must be performed to
compensate the misalignment. The following two show the example with or without concern
about misalignment respectively.

The work is directly applied to the cylinder as
excessive moment.

Wrong example Correct example
Since the cylinder is subject to direct moment of
load, guide shaft can work as only non-rotation
and operating failure may be caused.
Gap
The load is supported by guide shaft and the
clearance is provided to compensate misalignment.
The bracket is longer than center of axis of cylinder
to prevent moment applied to external slider.
Fig.4-4 [Ex.-4]
In wrong example shown of Fig. 4-2 [Ex.-2] (with external slider mounted directly on load base), the
misalignment between guide (orbit) and cylinder is not compensated and may induce operating failure. To
eliminate the misalignment and deflection of cylinder by self-weight, clearance is provided between
mounting bracket and cylinder as shown on correct example. Additionally, the mounting bracket should
be longer than center of axis of cylinder to minimize the moment applied to the external slider.
If the cylinder is mounted as shown on wrong example from Ex.1 to 4, external slider clamped is cylinder
tube strongly during operation and the wearing is worn so much as to cause operating failure.
As alternative solution for misalignment between cylinder and load, the rodless cylinder with specific
bracket (floating joint) is also by addition of -XC57 to suffix of part no. (Fig. 4-5) However, the floating joint
block obtained by –XC57 can’t be mounted to standard cylinder because –XC57 is adopting specific
external slider. Therefore, if –XC57 spec. is required for standard cylinder purchased independently, the
cylinder needs to be sent to SMC factory for repair with description of request “-XC57 spec.”

The misalignment can be checked
by the following procedure.
1) After installation of cylinder to application,
increase pressure of regulator gradually
before checking operation of cylinder at
operating pressure, and then calculate
min. pressure which enables smooth
operation of cylinder over full stroke.
2) The min. operating pressure obtained
after mounting of load (actual min.
operating pressure) is different from
one of independent cylinder, but the
difference should be focused.
3) The actual min. operating pressure is
sum of “sliding resistance of cylinder”,
“force to operate load” and “sliding
resistance of guide”. (Fig. 5)
Fig. 5 (Reference)
This means when misalignment is not
compensated enough, sliding resistance
of guide increases excessively.
Additionally, sliding resistance of external
slider increases and causes wearing to
wear so much as to induce operating failure.
If the load is mounted directly on the cylinder without other axes, ensure that weight of the load,
（Ⅱ）Without other axes combined (Switch rail is used as non-rotation device.)
stroke and moment are within allowable value with reference to Table 1 and 2.
If any of them exceeds corresponding allowable value, add the axis (LM guide etc.) to the cylinder.

２．Actuating force and moment
2-1) Actuating force
The actuating force of rodless cylinder is ideally equal to
thrust at center of axis of piston but normally, as shown on
Fig. 7-1, it is taken as FnN at the part away from the center
by Locm.
The relationship between Lo and Fn can be figured from Fig. 7-2.

2-2) Moment at stroke end
If the rodless cylinder is used for the load
with large inertia, the following operating
failures may be caused at stroke end.
As shown on Fig. 8-1, such a large inertial
load tries to keep on linear motion on the
guide thought the cylinder body stops at
stroke end. This produces the moment
applied to the cylinder body.
Fig. 8-1 Moment produced at stroke end
If the cylinder is kept operating in such a
condition, the wearing of external slider is
worn so much as to cause operating failure.
To avoid occurrence of the failure, as shown
on Fig. 8-2, use both of shock absorber and
stopper at the mounting space for the load
to absorb kinetic energy of the load and
adopt the mounting bracket longer than
center of axis of cylinder to prevent the
moment applied to the cylinder body.
Fig. 8-2 Countermeasure for moment at stroke end
３．Vertical Operation
If the cylinder is operated in vertical direction,
consider the same points as section 2.
3-1) Allowable load
Vertical operation makes the load act to
holding force of magnet and allows the load
less than horizontal operation.
Table 3 shows the allowable load for each size.

４．Intermediate Stop
4-1) Consider the following point to stop the
load on the way of stroke by external
stopper etc.
a) Operating pressure
Keep operating pressure below the limit
shown on Table 4. The operation at higher
pressure may cause thrust over holding
force to act and separate piston slider
and external slider from each other.
4-2) Consider the following points to realize
intermediate stop in pneumatic circuit.
a) Intermediate stop realized by the rodless
cylinder is not high accurate. If higher
accuracy is required for intermediate stop,
air hydraulic spec. (-X116) which combines
the cylinder with air hydraulic unit is
recommended.
(If it is required, contact SMC Sales division.)
b) Pay attention to kinetic energy generated by
load.
If the kinetic energy generated by the load
exceeds one to enable intermediate stop
shown on Table 5, be concerned about
possible runaway of load due to intermediate
stop by closed center valve.

5-1) Install air filter.
The rodless cylinder is non-lubrication type.
Install air filter to upstream near the valve and
adjust pneumatic pressure decreased to
desired set pressure by regulator.
5-2) Lubrication to compressed air
The rodless cylinder can be operated only
by initial lubrication at shipment. But if the
lubrication needs to be added due to
specifications, use Turbin oil class 1 (no
additive) ISO VG32. If the operation without
supply of additional lubrication is required
again, the cylinder needs to be sent to SMC
factory to enable re-application of adequate
amount of lubrication (grease).
5-3) For piping at both ends, change the
position of plug suitable for each operating
condition.
The piping port is made on axial direction of
cylinder and side face, but the port on side
face is plugged for shipment.
5-4) For common piping, remain switch
rail and plug installed. Removal of these
components may cause external leakage.
If the cylinder needs to be disassembled for
replacement of piston packing, soft wiper and
wearing, specific tool is required. The specific
tool can be ordered by part no. shown on Table 6.

6-1) If the cylinder body or piston is removed
from cylinder tube, displace the positions
of external slider and piston forcedly to
eliminate holding force and take out them
individually. If they are removed together with
holding force left, they become unable to
separate from each other by internal and
external magnet force.
6-2) Loosen hexagon socket head female on side
of end cover by hexagon wrench, take off
attachment ring from the end cover with specific
tool and then remove the end cover from
cylinder tube. After that, remove Circular stop
ring mounted on the external face of the cylinder
tube by snap ring pliers. The used magnet
has strong suction force and should be
handled with care when external slider and
piston slider are removed from cylinder tube.
6-3) Never disassembly the parts which compose
the magnet (external slider and piston slider).
The disassembly of them may deprive holding
force from the magnet and cause operating
failure.
6-4) Take off the watch for handling of external
slider and piston slider.
6-5) Handle external slider and piston slider with
care to protect the magnet from drop on the
floor and collision to the metal. And apply
the grease periodically on external face of
cylinder tube. The grease can be ordered
by the following part no.

7-1) Some of internal components of cylinder is made of iron. Protect them from direct splash of water etc.
If such a situation can’t be avoided, contact SMC separately.
7-2) Before piping, perform flashing inside the piping to prevent intrusion of dust and cutting chip inside
the cylinder.
7-3) Do not give any damage including flaw and gouge on external face of cylinder tube. These damage
may be followed by the damage of soft wiper, packing and wearing and finally operating failure may
be caused.
