Datasheet

1. For installation and removal, use an appropri-
ate pair of pliers (tool for installing a type C
retaining ring).
2. Even if a proper plier (tool for installing a type
C retaining ring) is used, it is likely to inflict
damage to a human body or peripheral
equipment, as a retaining ring may be flown
out of the tip of a plier (tool for installing a
type C retaining ring). Be much careful with
the popping of a retaining ring. Besides, be
certain that a retaining ring is placed firmly
into the groove of rod cover before supplying
air at the time of installment.
Retaining Ring Installation/Removal
Caution
The CQ2 series compact cylinders are
designed to create compact mechanical
equipment and promote space saving.
Thus, if it is used in the same manner as
conventional cylinders such as tie-rod
cylinders, it may degrade the performance.
Paysufficientattention to the operating
conditions when using.

1. Allowable lateral load
Lateral load that can apply to the piston rod
end is limited. If a cylinder is used witha
lateral load over the limit, it may cause air
leakage due to abnormal friction of seals,
galling of cylinder tubes and pistons, or
abnormal friction of the bearing part. The
lateral load applied to the piston rod must be
within the allowable range indicatedin this
catalogue. When the load exceeds the limit,
use a double rod cylinder, install a guide, or
change the bore size to suit the load in order
to make the load within the allowable range.
As a standard product, an anti-lateral load
type cylinder that is resistant to approx. 2
times more than the conventional compact
CQ2 series is also available (page 146).
2. Connection with a work piece
When a work piece is mounted on the piston
rod end, connect them aligning the center of
piston rod and a work piece. If they are
off-center, lateral load is generated and
phenomena mentioned in (1) may occur. In
order not to apply the off-center load, use of
a floating joint or simple joint is recom-
mended.
3. Simultaneous use of multiple cylinders
It is difficult to control the speed of
pneumatic cylinders. The following
conditions cause speed change: change in
supply pressure, load, temperature and
lubrication, performance difference of each
cylinder, deterioration of each part over time,
etc. Aspeed controller can be used to control
the speed of multiple cylinders simultane-
ously for a short period of time, but depend-
ing on conditions, it may not work as desired.
If multiple cylinders cannot operate simulta-
neously, unreasonable force is applied to the
piston rod because cylinder positions may
not be the same. This may cause abnormal
friction of seals and bearings, and galling of
cylinder tubes and pistons. Do not use an
application to operate several cylinders
simultaneously by adjusting cylinder speed.
If this is inevitable, use a high rigid guide
against load, so that the cylinder is not
damaged even when the each cylinder
output is slightly different.

Note) In the case of exclusive body type with ø32 to ø100 (-XB10) with the
stroke length exceeding 50 mm, reference values of the longitudinal
dimension (A/B dimension) will be the same as those with auto switch.
Refer to page 209 for details.
Note) Specify a spacer-installed type 1 with standard
model number for ordering an intermediate
stroke with a * mark. Refer to page 211 for
details.
For 55, 60, 65, 70, 80, 85, 90, and 95 stroke, exclusive bodies are
kept in inventory, enabling shorter delivery times.
