Airtac PSB Single Acting Compact Cylinder PSB12X60SR
The AirTAC Airtac PSB Single Acting Compact Cylinder PSB12X60SR 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 PSB12X60SR
The AirTAC PSB12X60SR is a JIS pen-size single-acting push cylinder with a 12mm bore and 60mm stroke. Air entering the single M5x0.8 port extends the Ø5 mm rod, while an internal spring ensures fail-safe retraction when exhaust drops. You get 42.9 N of net push at 0.5 MPa, or 65.5 N at the 0.7 MPa maximum. The built-in -S magnet enables position sensing.
This slim SUS304 stainless body saves space on tight jigs. A fixed TPU bumper cushions the stroke ends. For a 60mm extension, the slender rod needs an external guide to prevent side-loading. Plan for a safe working load of about 26 N (roughly 60% of the 0.5 MPa rating) to ensure smooth travel.
Airtac PSB Single Acting Compact Cylinder PSB12X60SR Technical Specifications
| Model | Airtac PSB Single Acting Compact Cylinder PSB12X60SR |
|---|---|
| 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 PSB12X60SR Is Used
Part Ejection
Pushes finished metal stamps out of a die. The spring-return fail-safe keeps the arm retracted if air pressure drops, preventing crashes.
Diverter Gate
Acts as a lightweight routing flap on a packaging line. One solenoid line drives the push stroke, simplifying tubing and cutting valve costs.
Clamp Release
Holds a wooden jig open during loading. Loss of plant air instantly springs the rod back to the safe home position, freeing the workpiece.
Is the Airtac PSB Single Acting Compact Cylinder PSB12X60SR the Right Cylinder?
This 12mm bore yields 42.9 N net push at 0.5 MPa. Stepping down to the 10mm bore drops net push to 29.8 N, while the 16mm bore raises it to 74.8 N. The internal return spring sets a 0.2 MPa minimum pressure before motion begins.
Confirm your ordering essentials: 12mm bore, 60mm stroke, -S magnet, R axial inlet, and your mounting bracket. The fixed TPU bumper only decelerates the final few millimeters, so meter-out the exhaust if moving heavy tooling.
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 PSB12X60SR FAQ
The net push force is 42.9 N at 0.5 MPa and 65.5 N at the 0.7 MPa maximum. The internal spring requires a minimum of 0.2 MPa before the rod extends, and it fails-safe retracts on air loss.
Yes, the -S suffix indicates a built-in piston magnet. It works with both reed and solid-state electronic switches. The stroke ends use a fixed TPU bumper, not an adjustable cushion.
