Airtac PSB Single Acting Compact Cylinder PSB12X30SR
The AirTAC Airtac PSB Single Acting Compact Cylinder PSB12X30SR 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 PSB12X30SR
The AirTAC PSB12X30SR is a JIS pen-size single-acting push cylinder, meaning air entering one M5x0.8 port extends the rod while an internal spring retracts it upon exhaust. This single-line operation cuts tubing complexity and ensures the rod safely pulls back if air pressure drops. It supplies 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 slim Ø5 mm rod, this 12 mm bore unit fits tight spaces on light end-of-arm tooling. It includes a built-in piston magnet for position sensing and an axial R back cover for inline plumbing. A fixed TPU bumper cushions the stroke ends.
Airtac PSB Single Acting Compact Cylinder PSB12X30SR Technical Specifications
| Model | Airtac PSB Single Acting Compact Cylinder PSB12X30SR |
|---|---|
| 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 PSB12X30SR Is Used
Part Ejection
Pushes finished metal stamps out of a press die. The spring-return design guarantees the ejector clears the mold when air is removed.
Diverter Gate
Actuates a lightweight routing flap on a packaging line. Single-solenoid valving simplifies wiring while maintaining fail-safe closure.
Clamp Release
Applies 42.9 N of push at 0.5 MPa to hold a small cardboard carton for labeling, then retracts instantly when the air supply stops.
Is the Airtac PSB Single Acting Compact Cylinder PSB12X30SR the Right Cylinder?
This 12 mm bore provides 42.9 N net push at 0.5 MPa. If you need less force, the Ø10 bore offers 29.8 N; for heavier tasks, the Ø16 bore yields 74.8 N. Because the internal spring opposes motion, a minimum 0.2 MPa is required before the rod begins to move. Plan for a safe working load of about 26 N (roughly 60 percent of the 0.5 MPa rating) to account for friction.
For vertical lifts, expect to raise about 2.2 kg safely with a 2:1 margin. The thin Ø5 mm rod handles coaxial thrust well, but add an external guide if side loads are present. Confirm your ordering essentials: 12 mm bore, 30 mm stroke, S magnet, R axial inlet, and your preferred mounting bracket.
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 PSB12X30SR FAQ
It delivers 42.9 N of net push at 0.5 MPa and 65.5 N at 0.7 MPa. Because the internal return spring opposes the air stroke, a minimum of 0.2 MPa is required to move the rod. The spring automatically retracts the rod on air loss.
Yes, the built-in S magnet works with both reed and electronic AirTAC switches. The fixed TPU bumper decelerates the rod over the last few millimeters of travel. At high speeds with heavy tooling mass, meter-out the exhaust or add an external shock absorber.
