Airtac PSB Single Acting Compact Cylinder PSB12X10R
The AirTAC Airtac PSB Single Acting Compact Cylinder PSB12X10R is a single acting, push type (spring return) pen-size mini cylinder with a Ø12mm bore and 10mm 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.

About the Airtac PSB Single Acting Compact Cylinder PSB12X10R
The AirTAC PSB12X10R is a JIS pen-size single-acting push cylinder, meaning air entering its single M5x0.8 port extends the Ø5 mm rod while an internal spring handles the retraction. This design requires only one solenoid line, cutting tubing and wiring complexity. It provides 42.9 N of net push force at 0.5 MPa and 65.5 N at 0.7 MPa, with the return spring force already subtracted.
Built with a SUS304 stainless barrel and a slim mini body, it fits easily into tight jigs and light end-of-arm tooling. If air pressure drops, the spring pulls the rod home, creating a fail-safe retracted state for safe part ejection or clamping release. The unit relies on a fixed TPU bumper at each end to decelerate motion over the last few millimeters of travel.
Airtac PSB Single Acting Compact Cylinder PSB12X10R Technical Specifications
| Model | Airtac PSB Single Acting Compact Cylinder PSB12X10R |
|---|---|
| Series | PSB JIS pen-size mini cylinder |
| Bore size | Ø12 mm |
| Rod diameter | Ø5 mm |
| Stroke | 10 mm |
| Acting type | Single acting, push type (spring return) |
| Port size | M5×0.8 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.2 – 0.7 MPa |
| Proof pressure | 1.2 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 50 – 800 mm/s |
| Return | Return spring (push by air) |
| Max standard stroke | Up to 60 mm |
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.
Net Push Force (Ø12mm)
| Pressure | Net push force |
|---|---|
| 0.5 MPa | 42.9 N |
| 0.7 MPa (max) | 65.5 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.

Where the Airtac PSB Single Acting Compact Cylinder PSB12X10R Is Used
Part Ejection
Uses the spring-return push to eject small machined components from a fixture, ensuring the rod safely retracts if the air supply fails.
Flap Folding
Extends to fold carton flaps on a packaging line, relying on the compact pen-size body to fit within narrow machine clearances.
Clamp Release
Acts as a fail-safe clamp release on an assembly jig, automatically opening the clamp to a retracted position during an air loss event.
Is the Airtac PSB Single Acting Compact Cylinder PSB12X10R the Right Cylinder?
This 12 mm bore, 10 mm stroke model offers 42.9 N net push at 0.5 MPa. If you need less force, the Ø10 bore variant provides 29.8 N at the same pressure; for heavier tasks, the Ø16 bore yields 74.8 N. Because the internal spring opposes motion, a minimum operating pressure of 0.2 MPa is required before the rod begins to move. Plan for a safe working load of about 26 N, which accounts for seal friction and smooth travel at roughly 60 percent of the theoretical force.
When ordering, confirm the 12 mm bore, 10 mm stroke, and the R axial inlet configuration. This specific unit lacks the magnetic sensor option. Keep in mind the thin Ø5 mm rod is designed for coaxial thrust, so over its 10 mm stroke or under off-axis loads, add an external guide or linear bearing to prevent side load damage.
Quick checklist
- ✓ Net push force at your working pressure
- ✓ Only one air line / solenoid needed
- ✓ Fail-safe retract on air loss
- ✓ Magnet (S) for sensors?
- ✓ Stroke ≤ 60 mm (single-acting limit)
- ✓ Keep the load coaxial — avoid side load
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.2 – 0.7 MPa operating pressure.
- check Allow for spring force in the stroke direction.
- check Do not add an external return mechanism.
- check Keep the load coaxial; avoid side load on the thin rod.
- check Do not dismantle the front or back cover.
Airtac PSB Single Acting Compact Cylinder PSB12X10R FAQ
The net push force is 42.9 N at 0.5 MPa and 65.5 N at 0.7 MPa, with the spring force already deducted. Because the internal spring opposes the air stroke, a minimum operating pressure of 0.2 MPa is required before the rod moves.
A fixed TPU bumper at each end decelerates the piston over the last few millimeters of travel but is not adjustable. If air pressure is lost, the internal spring ensures the rod fails-safe to a fully retracted position rather than staying mid-stroke.
