The AirTAC Airtac PSB Single Acting Compact Cylinder PSB10X40U is a single acting, push type (spring return) pen-size mini cylinder with a Ø10mm bore and 40mm stroke. A single air port drives the push stroke; the built-in return spring resets the rod when air is released, so only one solenoid line is needed.
The AirTAC PSB10X40U is a JIS pen-size single-acting push cylinder with a 10 mm bore and 40 mm stroke. Air entering the single M5x0.8 port extends the Ø4 mm rod, while an internal spring ensures fail-safe retraction upon air loss. The U suffix designates a 90-degree side inlet, keeping plumbing flat against tight jig frames. It provides 29.8 N of net push at 0.5 MPa and 45.5 N at 0.7 MPa, with the return spring force already deducted.
Built with a SUS304 stainless barrel and rod, this slim mini body resists corrosion in damp environments. The fixed TPU bumper decelerates the stroke near the ends. For practical sizing, plan for a safe working load of about 18 N, which accounts for roughly 60 percent of the rated thrust to ensure smooth travel against seal friction.

The spring holds the rod retracted; applying air pushes the rod out, and removing air lets the spring return it. Forces below are the NET spring-deducted values from the AirTAC thrust table. Confirm against the product label before installation.
| Pressure | Net push force |
|---|---|
| 0.5 MPa | 29.8 N |
| 0.7 MPa (max) | 45.5 N |
These are the usable push forces after the return spring is subtracted, taken directly from the AirTAC single-acting thrust table. Minimum operating pressure is set by the spring, so this model needs at least the lower pressure shown to move.

Pushes machined pins off a conveyor lane with 29.8 N of thrust, relying on the spring to retract safely when air drops.
Extends to fold light cardboard flaps on a packaging line, with the 90-degree side inlet keeping the footprint minimal.
Actuates a lightweight holding clamp during assembly; the spring guarantees the clamp retracts open on air loss.
This 10 mm bore yields 29.8 N net push at 0.5 MPa. If your application needs less force, stepping down to a 6 mm bore provides 10.6 N; moving up to a 12 mm bore offers 42.9 N. The internal return spring requires a minimum operating pressure of 0.2 MPa before the rod can move. Because the rod is only Ø4 mm, adding an external guide or linear bearing is advised for this 40 mm stroke to prevent side-load damage.
Confirm your ordering essentials: 10 mm bore, 40 mm stroke, no magnet, U side inlet, and your preferred mounting bracket. The U configuration routes the M5x0.8 air line perpendicular to the body for compact installations.
Quick checklist
The net push force is 29.8 N at 0.5 MPa and 45.5 N at the 0.7 MPa maximum. Because an internal spring opposes the air stroke, a minimum operating pressure of 0.2 MPa is required before the rod moves, and the rod fails safely retracted without air.
It uses a fixed TPU bumper at each end to decelerate the last few millimeters of travel. The bumper is not adjustable; at higher speeds with real tooling mass, meter-out the exhaust or add an external shock absorber to prevent bottoming out.
