Airtac PSB Single Acting Compact Cylinder PSB12X15SU
The AirTAC Airtac PSB Single Acting Compact Cylinder PSB12X15SU is a single acting, push type (spring return) pen-size mini cylinder with a Ø12mm bore and 15mm 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 PSB12X15SU
The AirTAC PSB12X15SU is a JIS pen-size single-acting push cylinder that extends via one M5x0.8 air port and retracts via an internal spring. It delivers 42.9 N of net push at 0.5 MPa. The U suffix indicates a 90-degree side inlet for flat plumbing, and the S suffix adds a piston magnet for solid-state or mechanical switches.
Built with a SUS304 stainless rod and barrel, this slim body fits tight jigs. It includes a fixed TPU bumper to decelerate the stroke's final millimeters. Plan for a safe working load of roughly 26 N to account for seal friction and smooth travel.
Airtac PSB Single Acting Compact Cylinder PSB12X15SU Technical Specifications
| Model | Airtac PSB Single Acting Compact Cylinder PSB12X15SU |
|---|---|
| Series | PSB JIS pen-size mini cylinder |
| Bore size | Ø12 mm |
| Rod diameter | Ø5 mm |
| Stroke | 15 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 PSB12X15SU Is Used
Part Ejector
Pushes finished parts off a machining fixture; the spring safely pulls the rod back if compressed air drops.
Gate Diverter
Sorts small packages on a line by extending a 15 mm stroke to deflect items into a secondary lane.
Flap Folder
Tucks carton flaps during automated packing sequences using a compact pen-size footprint.
Is the Airtac PSB Single Acting Compact Cylinder PSB12X15SU the Right Cylinder?
This 12 mm bore provides 42.9 N net push at 0.5 MPa. Stepping down to a 10 mm bore yields 29.8 N, while a 16 mm bore offers 74.8 N. The internal spring ensures the rod fails safe to the retracted position on air loss, though a minimum 0.2 MPa is required to overcome it. Confirm your ordering essentials: 12 mm bore, 15 mm stroke, S magnet, U side inlet, and your 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 PSB12X15SU FAQ
The net push force is 42.9 N at 0.5 MPa and 65.5 N at the 0.7 MPa maximum. Because the internal spring opposes motion, a minimum of 0.2 MPa is required before the rod extends.
The S suffix provides a built-in piston magnet for AirTAC reed or electronic switches. The cylinder uses a fixed TPU bumper that decelerates the last few millimeters of travel; for heavy tooling at high speeds, add an external shock absorber.
