Airtac PSB Single Acting Compact Cylinder PSB12X60CB
The AirTAC Airtac PSB Single Acting Compact Cylinder PSB12X60CB 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 PSB12X60CB
The AirTAC PSB12X60CB 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 Ø5mm rod, while an internal spring retracts it upon exhaust release. This fail-safe design ensures the rod returns home if air pressure drops, requiring only one solenoid line for simpler tubing. It delivers 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 rod, the slim mini body fits tight jigs and light end-of-arm tooling. The CB double clevis back cover accommodates pivoting loads. A fixed TPU bumper at each end decelerates the stroke, though at higher speeds with real tooling mass you should meter-out the exhaust or add an external shock absorber. Plan for a safe working load of about 26 N, which accounts for seal friction and smooth travel.
Airtac PSB Single Acting Compact Cylinder PSB12X60CB Technical Specifications
| Model | Airtac PSB Single Acting Compact Cylinder PSB12X60CB |
|---|---|
| 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 PSB12X60CB 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.
Carton Flap Folder
Extends to fold minor corrugated flaps on a packaging line, with the fail-safe retract preventing jams during unexpected air loss events.
Gate Diverter
Pushes a lightweight routing gate on a sorting machine; the single air line simplifies wiring while the TPU bumper softens the end-of-stroke impact.
Is the Airtac PSB Single Acting Compact Cylinder PSB12X60CB the Right Cylinder?
This 12mm 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. The internal return spring sets a 0.2 MPa minimum pressure before motion begins. At 60mm stroke, the slender Ø5mm rod is meant for coaxial thrust—add an external linear bearing if the application involves off-axis loads.
Confirm your ordering essentials: 12mm bore, 60mm stroke, CB double clevis inlet, and no magnet (omit the S suffix). The rod-end thread is M10x1.0. For applications needing force in both directions without spring loss, consider the PB double-acting series instead.
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 PSB12X60CB FAQ
The net push force is 42.9 N at 0.5 MPa and 65.5 N at 0.7 MPa (maximum pressure). Because the internal return spring opposes the air stroke, a minimum of 0.2 MPa is required before the rod moves. The spring ensures the rod is fail-safe retracted on air loss.
A fixed TPU bumper at each end decelerates the rod over the last few millimeters; it is not adjustable. Above mid-speed with heavy tooling, meter-out the exhaust or add an external shock absorber. The spring drives the return stroke, so there is no powered retract.
