Air Cylinder

Series

ø20, ø25, ø32, ø40

Longer life, over 1.5 times longer

The cylinder’s mounting and the machining accuracy of the parts have

been improved. Furthermore, the shapes and the materials of the seals

have been improved to enhance their wear resistance. As a result, the

cylinder’s life has been dramatically increased to 1.5 times that of Series

CM.

Compact and lightweight

The tube is made of stainless steel and the

cover and the piston are

made of aluminum. Through

a compact design, it weighs

30 to 40% less than Series

CM. The Lateral width of the

cover has been requiring

less installation space.

Excellent dust resistance

A special shaped rod seal with a composite

formed dust lip has been adopted. It prevents

the intrusion of external dust, enabling the

cylinder to be operated in unfavorable

environments containing large amounts of

cutting chips.

Reduced piston rod deflection

The clearance between the bushing and the

piston rod, and between the tube and the wear

ring have been decreased to achieve higher

accuracy. Thus, the deflection of the piston rod

has been decreased to 1/2 of Series CM.

Replaceable rod seal

The rod seal, which is the first part to wear out in

a cylinder, can be replaced. This extends the life

of the cylinder, and is economical. The seal can

be replaced with the cylinder mounting, thus

requiring less manpower.

A tube that is resistant

against external impacts

To prevent deformation or damage caused by

external impacts, a stainless tube with a thicker wall

has been adopted to increase its strength.

Furthermore, the strength of the support bracket

has been increased.

Easy installation

Because the rod cover and the head cover

have wide surfaces, a wrench can be

placed over the cover during installation,

thus facilitating installation.

High speed drive possible

The cushion function can be selected in

accordance with the drive speed condition to be

used. Therefore, it can support a high-speed

drive.

(Standard equipment)

Air cushion······50 to 1000 mm/s

Improved installation accuracy

The cylinder body and the mounting support bracket

have been made with an even higher level of

accuracy.

simplifies the installation work and prolongs the life of

the cylinder.
