Airtac PSB Single Acting Compact Cylinder PSB12X5SCB
The AirTAC Airtac PSB Single Acting Compact Cylinder PSB12X5SCB is a single acting, push type (spring return) pen-size mini cylinder with a Ø12mm bore and 5mm 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 PSB12X5SCB
The AirTAC PSB12X5SCB is a JIS pen-size single-acting push cylinder with a 12mm bore and 5mm 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 reducing valve costs. Because the spring constantly opposes the air stroke, the unit provides a net usable push force of 42.9N at 0.5 MPa and 65.5N at 0.7 MPa.
Built with a SUS304 stainless barrel and a slim mini body, it fits easily into tight jigs and light end-of-arm tooling. The CB double clevis mount accommodates pivoting loads, and the integrated piston magnet allows position sensing with reed or electronic switches. A fixed TPU bumper at each end decelerates the rod over the last few millimeters of travel.
Airtac PSB Single Acting Compact Cylinder PSB12X5SCB Technical Specifications
| Model | Airtac PSB Single Acting Compact Cylinder PSB12X5SCB |
|---|---|
| Series | PSB JIS pen-size mini cylinder |
| Bore size | Ø12 mm |
| Rod diameter | Ø5 mm |
| Stroke | 5 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 PSB12X5SCB Is Used
Pivoting Part Ejector
Uses the CB double clevis to swing and push finished plastic parts off an injection mold conveyor, relying on the spring to safely retract the rod when air is cut.
Light Duty Clamp
Holds small aluminum workpieces against a machining stop with 42.9N of push force at 0.5 MPa, releasing instantly via spring return upon exhaust.
Component Gate
Acts as a compact diverter gate on a PCB assembly line, extending to block off faulty boards while the fail-safe spring clears the path during power loss.
Is the Airtac PSB Single Acting Compact Cylinder PSB12X5SCB the Right Cylinder?
When sizing this 12mm bore actuator, plan for a safe working load of about 26N, which assumes a conservative 60 percent of the 42.9N net push at 0.5 MPa. For vertical lifting, this translates to safely raising roughly 2.2kg with a 2:1 safety margin. If your application demands less force, the adjacent Ø10 bore offers 29.8N at 0.5 MPa; if more thrust is needed, stepping up to the Ø16 bore yields 74.8N. The internal return spring ensures the rod fails-safe to a retracted position on air loss, but it also establishes a 0.2 MPa minimum operating pressure before motion begins.
Confirm your ordering essentials: 12mm bore, 5mm stroke, S for the piston magnet, CB double clevis inlet, and any required mounting brackets. The thin Ø5mm rod is engineered for coaxial thrust, so over long strokes or off-axis loads, add an external guide or linear bearing to prevent side-loading damage.
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 PSB12X5SCB FAQ
The net usable push force is 42.9N at 0.5 MPa and 65.5N at the 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 spring ensures the rod fails-safe to a retracted position on air loss.
The S suffix denotes a built-in piston magnet compatible with AirTAC reed or electronic switches. Cushioning is handled by a fixed TPU bumper at each end that decelerates the rod over the last few millimeters; it is not adjustable, so at higher speeds with real tooling mass, meter-out the exhaust or add an external shock absorber.
