Overview for CJP Mini Air Cylinder

Single-acting CJP Pin Cylinder has a compact brass body with an unthreaded stainless-steel piston rod, and it has panel mounting for installation through walls or panels. The CJP Mini Air Cylinder (also called pneumatic cylinder) has a pin-style compact body and a single unthreaded piston rod for linear movement applications with tight space restrictions. The CJP Cylinder's body is crafted in nickel-plated brass for higher corrosion resistance than regular brass, and its piston rod is made of stainless steel to resist corrosion and scaling. The single-acting Mini Pneumatic Cylinder uses airflow through its single air port for rod extension and an internal spring in the cylinder barrel's rod end for rod retraction to produce continued movement. It has nitrile butadiene rubber (NBR) seals to contain air and protect the barrel and piston rod. This CJP Cylinder has panel mounting and comes with both mounting and rod end nuts for installations through walls or panels.

Application Examples for CJP Mini Air Cylinder (Pin Cylinder)

A short stroke miniature cylinder with a shorter overall length.
The installation space can be significantly reduced because this CJP Cylinder can be recessed directly into a machine body or installed on a panel. Thus, the machine can be made more compact.

Allowable Kinetic Energy

Caution
When driving an inertial load, operate a cylinder with kinetic energy within the allowable value. The range in the chart below that is delineated by bold solid lines indicates the relation between load mass and maximum driving speeds.

Bore size (mm)	4	6	10	15
Piston speed (m/s)	0.05 ~ 0.5
Allowable kinetic energy (J)	0.5 x10-3	3x10-3	8x10-3	19x10-3

Allowable Lateral Load

Strictly observe the limiting range of lateral load on a piston rod. (Refer to the below graph.) If CJP Cylinder is used beyond the limits, it may shorten the machine life or cause damage.

* Please be aware that cylinder speed may slow down on the retracting side when using the above one-touch fittings and miniature fittings with a cylinder bore size of ø15.

Hose nipple

In addition to the above fittings and hose nipples, the below fittings can also be attached to the cylinder. When using the below fittings be sure to provide a speed controller after adjusting it to 500 mm/s or less.

* For details about one-touch fittings, miniature fittings and speed controllers (applicable tubing O.D. ø2 only), refer to the catalog ES50-25 (B edition or later).
Also, for details about speed controllers (applicable tubing O.D. ø3.2 to ø6), refer to Best Pneumatics No. 6.
* Refer to the Fittings and Tubing Precautions (Best Pneumatics No. 6) for how to handle one-touch fittings.

Mounting

Caution
Do not use it in such a way that a load could be applied to the piston rod during the retraction. The spring that is built into the CJP Mini Air Cylinder provides only enough force to retract the piston rod. Thus, if a load is applied, the piston rod may not be able to retract to the end of the stroke.
