Selection
1. When using a cylinder with long strokes, implement
an intermediate support.
When using a cylinder with long strokes, implement an inter-
mediate support to prevent the tube from sagging and being
deflected by vibration or an external load.
Refer to the “Guide to Side Support Application” on page 12.
2. For intermediate stops, use a dual-side pressure
control circuit.
Since the mechanically jointed rodless cylinders have a
unique seal structure, slight external leakage may occur. Con-
trolling intermediate stops with a 3-position valve cannot hold
the stopping position of the slide table (slider). The speed at
the restarting state also may not be controllable. Use the dual-
side pressure control circuit with a PAB-connected 3-position
valve for intermediate stops.
3. Cautions on less frequent operation
When the cylinder is used extremely infrequently, operation
may be interrupted in order for anchoring and a change lubri-
cation to be performed or service life may be reduced.
Caution
Mounting
5. Fixed parts of the cylinder on both ends must have
at least 5 mm of contact between where the bottom
of the cylinder tube and the equipment surface.
Caution
Mounting
1. Do not apply strong impacts or excessive moment
to the slide table (slider).

when mounting workpieces.
2. Do not mount cylinders as they are twisted.
When mounting, be sure for a cylinder tube not to be twisted.
The flatness of the mounting surface is not appropriate, the
cylinder tube is twisted, which may cause air leakage due to
the detachment of a seal belt, damage a dust seal band, and
cause malfunctions.
3. Do not mount a slide table on the fixed equipment
surface.
It may cause damage or malfunctions since an excessive load
is applied to the bearing.
4. Consult SMC when mounting in a cantilevered way.
Since the cylinder body deflects, it may cause malfunctions.
When using it this way, please contact SMC sales representa-
tives.
Caution
1. Do not use in an environment where the cylinder is
exposed to coolant, cutting oil, water drops, adhe-
sive foreign matter, dust, etc. and avoid use with
compressed air containing drainage and foreign
matter.
s&OREIGNMATTERORLIQUIDSONTHECYLINDEr’s interior or exterior
can wash out the lubricating grease, which can lead to dete-
rioration and damage of dust seal band and seal materials,
causing a danger of malfunction.
When operating in locations with exposure to water and oil,
or in dusty locations, provide protection such as a cover to
prevent direct contact with the cylinder, or mount so that the
dust seal band surface faces downward, and operate with
clean compressed air.
2. Carry out cleaning and grease application suitable
for the operating environment.
Carry out cleaning regularly when using in an operating
environment in which the product is likely to get dirty.
After cleaning, be sure to apply grease to the top side of the
cylinder tube and the rotating part of the dust seal band. Apply

room.
If you are considering using it in a clean room, please contact
SMC sales representatives.
Operating Environment
Warning
6. Do not generate negative pressure in the cylinder
tube.
Take precautions under operating conditions in which nega-
tive pressure is generated inside the cylinder by external forc-
es or inertial forces. Air leakage may occur due to separation

inder by forcibly moving it with an external force during the trial
operation or dropping it with its own weight under the non-
pressure state, etc. When the negative pressure is generated,
slowly move the cylinder by hand and move the stroke back
and forth. After doing so, if air leakage still occurs, please con-
tact SMC sales representatives.
