There is no particulate generation from sliding, because the
construction avoids contact between the cylinder tube’s
exterior surface and the slide table’s interior surface.
Non-contact construction
The specially treated linear guide
achieves low particulate generation,
high linearity and high precision.

Low particle generation: 1/20
High cleanliness is achieved with non-contact
construction of the cylinder tube exterior and a
stainless steel linear guide (specially treated).
Particle generation has been reduced to 1/20
compared to series 12-CY3B (previous SMC
product) even without vacuum suction.
(compared to previous series)
Note 1) This chart indicates the level of cleanliness inside the measurement chamber.
Note 2) The vertical axis shows the number of particles per unit volume (1 m3) of air which
are no smaller than the particle size shown on the horizontal axis.
Note 3) The gray lines show the upper concentration limit of the cleanliness class based
on Fed.Std.209E-1992.
Note 4) The plots indicate the 95% upper reliability limit value for time series data up to
500 thousand operation cycles. (Cylinder: CYP32-200, Workpiece weight: 5 kg,
Average speed: 200 mm/s)
Note 5) The data above provide a guide for selection but is not guaranteed.
Piping port positions can be selected to accommodate the installation.
Note) Plugs are installed in ports other than those indicated for the model.

A special cylinder tube is employed using
extruded aluminum material. Even long
strokes are not subject to deflection because
of direct attachment to the cylinder body, and
non-contact construction is achieved through
combination with a linear guide.
