Airtac PSB Single Acting Compact Cylinder PSB12X60SU
The AirTAC Airtac PSB Single Acting Compact Cylinder PSB12X60SU is a single acting, push type (spring return) pen-size mini cylinder with a Ø12mm bore and 60mm 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 PSB12X60SU
The AirTAC PSB12X60SU 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 release. This fail-safe design ensures the rod pulls back home automatically if air pressure drops, keeping your clamp or ejector clear. It delivers 42.9 N of net push at 0.5 MPa and 65.5 N at 0.7 MPa, with the return spring force already subtracted from these usable figures.
Built with a SUS304 stainless steel rod and barrel, this slim mini body fits easily into tight jigs and light end-of-arm tooling. The 60 mm stroke represents the maximum single-acting limit for this bore. A fixed TPU bumper at each end cushions the last few millimeters of travel. Because the internal spring opposes the air stroke, a minimum operating pressure of 0.2 MPa is required before the piston moves.
Airtac PSB Single Acting Compact Cylinder PSB12X60SU Technical Specifications
| Model | Airtac PSB Single Acting Compact Cylinder PSB12X60SU |
|---|---|
| Series | PSB JIS pen-size mini cylinder |
| Bore size | Ø12 mm |
| Rod diameter | Ø5 mm |
| Stroke | 60 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 PSB12X60SU Is Used
Stamping Ejector
Pushes small stamped parts out of a die on a press line. The spring-return design guarantees the ejector pin retracts clear of the tooling on air loss, preventing crash damage.
Package Diverter
Acts as a slim routing gate on a packaging conveyor. The 90-degree side inlet keeps plumbing flat against the frame, saving vertical space in tight transfer zones.
Clamp Release
Applies 42.9 N of holding push at 0.5 MPa to secure a light workpiece during machining. Exhausting the single air line instantly retracts the rod to release the part.
Is the Airtac PSB Single Acting Compact Cylinder PSB12X60SU the Right Cylinder?
This 12 mm bore model provides 42.9 N net push at 0.5 MPa. If your task needs less force, the 10 mm bore version offers 29.8 N at the same pressure; if you need more power, stepping up to the 16 mm bore yields 74.8 N. Plan for a safe working load of about 26 N, which is roughly 60 percent of the 0.5 MPa rating, to account for seal friction and smooth travel. For vertical lifts, expect to raise about 2.2 kg safely with a 2:1 margin.
The U option designates a 90-degree side air inlet for flat plumbing in confined spaces. Because the rod is only 5 mm thick and the stroke is a long 60 mm, add an external guide or linear bearing for any off-axis loads to prevent bending. When ordering, confirm the 12 mm bore, 60 mm stroke, S magnet for electronic or reed switches, U side inlet, and your mounting bracket choice.
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 PSB12X60SU FAQ
The net push force is 42.9 N at 0.5 MPa and 65.5 N at 0.7 MPa, with the return spring force already deducted. A minimum operating pressure of 0.2 MPa is required to overcome the spring and move the rod.
It uses a fixed TPU bumper at each end to decelerate the last few millimeters of travel. The S suffix indicates a built-in piston magnet for position sensing, compatible with AirTAC reed or electronic switches.
