Airtac PSB Single Acting Compact Cylinder PSB12X10SCB
The AirTAC Airtac PSB Single Acting Compact Cylinder PSB12X10SCB 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 PSB12X10SCB
The AirTAC PSB12X10SCB is a JIS pen-size single-acting push cylinder with a 12mm bore and 10mm stroke. Air entering the M5x0.8 port extends the Ø5mm rod, while an internal spring ensures fail-safe retraction upon exhaust. This design requires only one solenoid line, cutting tubing and wiring complexity. It yields 42.9 N of net push at 0.5 MPa and 65.5 N at 0.7 MPa.
Built with a SUS304 stainless barrel and a CB double clevis, this unit accommodates pivoting loads. The -S suffix indicates a built-in piston magnet compatible with AirTAC reed or electronic switches. A fixed TPU bumper cushions the stroke ends. For practical sizing, plan for a safe working load of roughly 26 N, which accounts for seal friction and smooth travel.
Airtac PSB Single Acting Compact Cylinder PSB12X10SCB Technical Specifications
| Model | Airtac PSB Single Acting Compact Cylinder PSB12X10SCB |
|---|---|
| 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 PSB12X10SCB Is Used
Clevis-Mounted Part Ejector
Pivots on the CB clevis to push finished metal stamps off a machining center, relying on the spring to retract safely when air is cut.
Package Diverter Gate
Extends to redirect small cartons on a packaging line, using the 42.9 N push force at 0.5 MPa to nudge items smoothly.
Light Clamping Arm
Holds a thin workpiece in place during a secondary drilling operation, releasing instantly on air loss to prevent tool crashes.
Is the Airtac PSB Single Acting Compact Cylinder PSB12X10SCB the Right Cylinder?
When sizing this 12mm bore unit, consider the neighboring options. Dropping to a 10mm bore reduces the net push to 29.8 N at 0.5 MPa, while stepping up to a 16mm bore increases it to 74.8 N. The internal return spring mandates a minimum operating pressure of 0.2 MPa before motion begins. The rod safely stays retracted if air pressure drops.
Confirm your ordering essentials: 12mm bore, 10mm stroke, S magnet, CB double clevis, and an M10x1.0 rod-end thread. The Ø5mm piston rod handles coaxial thrust well, but over long strokes or 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 PSB12X10SCB FAQ
The net push force is 42.9 N at 0.5 MPa and 65.5 N at 0.7 MPa (maximum pressure). Because the internal return spring opposes the air stroke, a minimum operating pressure of 0.2 MPa is required before the rod moves.
The CB back cover provides a double clevis mount for pivoting applications. A fixed TPU bumper decelerates the rod at the stroke ends, but at higher speeds with real tooling mass, you should meter-out the exhaust or add an external shock absorber.
