Airtac PSB Single Acting Compact Cylinder PSB12X30SCB
The AirTAC Airtac PSB Single Acting Compact Cylinder PSB12X30SCB is a single acting, push type (spring return) pen-size mini cylinder with a Ø12mm bore and 30mm 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 PSB12X30SCB
The AirTAC PSB12X30SCB is a JIS pen-size single-acting push cylinder with a 12mm bore and 30mm stroke. Air entering the single M5x0.8 port extends the Ø5mm rod, while an internal spring retracts it upon exhaust release. This design requires only one solenoid line, simplifying tubing and wiring. It provides 42.9 N of net push force at 0.5 MPa, with the return spring deduction already applied.
Built with a SUS304 stainless barrel and rod, the slim mini body fits tight jigs and light end-of-arm tooling. The CB double clevis back cover accommodates pivoting loads. A built-in piston magnet allows position sensing with reed or electronic switches. The fixed TPU bumper decelerates the stroke over the final few millimeters.
Airtac PSB Single Acting Compact Cylinder PSB12X30SCB Technical Specifications
| Model | Airtac PSB Single Acting Compact Cylinder PSB12X30SCB |
|---|---|
| Series | PSB JIS pen-size mini cylinder |
| Bore size | Ø12 mm |
| Rod diameter | Ø5 mm |
| Stroke | 30 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 PSB12X30SCB Is Used
CNC Part Ejection
Pushes finished aluminum parts out of a machining center. The spring-return design guarantees the ejector clears the workspace if compressed air drops unexpectedly.
Package Diverter Gate
Actuates a lightweight routing flap on a packaging line. The CB double clevis accommodates the pivot arc while the single air line cuts valve costs.
Print Head Clamp
Applies 26 N of holding force to secure a substrate during marking. The fail-safe retract releases the clamp automatically when the machine stops.
Is the Airtac PSB Single Acting Compact Cylinder PSB12X30SCB the Right Cylinder?
This 12mm bore generates 42.9 N net push at 0.5 MPa. Stepping down, the Ø10 bore yields 29.8 N; stepping up, the Ø16 bore provides 74.8 N at the same pressure. Plan for a safe working load of about 26 N (roughly 60 percent of the rated force) to account for seal friction. Vertically, it lifts about 2.2 kg with a 2:1 safety margin.
The internal spring sets a 0.2 MPa minimum operating pressure before motion begins and ensures fail-safe retraction on air loss. The Ø5mm rod handles coaxial thrust well, but add an external guide for off-axis loads. Confirm your ordering essentials: 12mm bore, 30mm stroke, S magnet, CB double clevis, and mounting brackets.
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 PSB12X30SCB FAQ
The net usable push force is 42.9 N at 0.5 MPa and 65.5 N at 0.7 MPa (maximum). Because the internal return spring opposes the air stroke, a minimum operating pressure of 0.2 MPa is required before the rod moves, and the rod fails safe to the retracted position on air loss.
The -S suffix indicates a built-in piston magnet compatible with reed or electronic switches. Cushioning relies on a fixed TPU bumper that decelerates the rod over the last few millimeters; at high speeds with heavy tooling mass, meter-out the exhaust or add an external shock absorber.
