Airtac PSB Single Acting Compact Cylinder PSB12X10U
The AirTAC Airtac PSB Single Acting Compact Cylinder PSB12X10U 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 PSB12X10U
The AirTAC PSB12X10U is a JIS pen-size single-acting push cylinder with a 12mm bore and 10mm stroke. Air entering the single M5x0.8 port extends the Ø5mm rod, while an internal spring ensures a fail-safe retracted position when exhaust occurs. Because the spring force is already subtracted, you get a true net push of 42.9N at 0.5 MPa and 65.5N at the 0.7 MPa maximum. The U suffix denotes a 90-degree side inlet, keeping plumbing flat against your jig.
Built with a SUS304 stainless barrel and rod, this slim mini body resists corrosion in damp environments. A fixed TPU bumper at each end cushions the stroke. For practical sizing, plan for a safe working load of about 26N (roughly 60% of the 0.5 MPa figure) to account for seal friction. This equates to lifting about 2.2kg vertically with a sane 2:1 margin.
Airtac PSB Single Acting Compact Cylinder PSB12X10U Technical Specifications
| Model | Airtac PSB Single Acting Compact Cylinder PSB12X10U |
|---|---|
| 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 PSB12X10U Is Used
Part Ejection
Pushes finished metal stamps out of a die on a press line. The spring-return design guarantees the ejector clears the mold when the machine halts or loses air pressure.
Gate Diverter
Acts as a compact sorting gate on a packaging conveyor. The 90-degree side inlet keeps the profile flat against the belt frame, routing small cartons without snagging.
Clamp Release
Applies a light holding push against a workpiece on a test fixture. Releasing air drops the clamp instantly, allowing operators to swap components quickly and safely.
Is the Airtac PSB Single Acting Compact Cylinder PSB12X10U the Right Cylinder?
This 12mm bore provides 42.9N net push at 0.5 MPa. If your task needs less force, stepping down to the 10mm bore yields 29.8N; moving up to the 16mm bore provides 74.8N. The internal return spring sets a 0.2 MPa minimum pressure before motion begins, and the rod safely retracts on air loss. Confirm your ordering essentials: 12mm bore, 10mm stroke, U side inlet, and no magnet (S). The thin Ø5mm rod handles coaxial thrust well, but over long strokes or off-axis loads, add an external 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 PSB12X10U FAQ
The net push force is 42.9N at 0.5 MPa and 65.5N at 0.7 MPa (the maximum operating pressure). The internal return spring requires a minimum of 0.2 MPa before the rod begins to move. These figures already account for the spring deduction.
It uses a fixed TPU bumper at each end to decelerate the stroke over the last few millimeters. The bumper is not adjustable. At higher speeds with heavy tooling mass, meter-out the exhaust or add an external shock absorber to prevent bottoming out.
