Airtac PSB Single Acting Compact Cylinder PSB10X25R
The AirTAC Airtac PSB Single Acting Compact Cylinder PSB10X25R is a single acting, push type (spring return) pen-size mini cylinder with a Ø10mm bore and 25mm 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 PSB10X25R
The AirTAC PSB10X25R is a JIS pen-size single-acting push cylinder that extends via one M5x0.8 air port and retracts via an internal spring. It supplies 29.8 N of net push at 0.5 MPa, reaching 45.5 N at the 0.7 MPa maximum. Because the spring constantly opposes the air stroke, these figures already reflect the usable force after spring deduction.
This slim SUS304 stainless build fits tight jigs and light end-of-arm tooling. The R suffix specifies an axial air inlet for in-line plumbing. A single solenoid line drives the motion, cutting tubing complexity compared to double-acting models. If air pressure drops, the built-in spring ensures the rod fails safely in the retracted position.
Airtac PSB Single Acting Compact Cylinder PSB10X25R Technical Specifications
| Model | Airtac PSB Single Acting Compact Cylinder PSB10X25R |
|---|---|
| Series | PSB JIS pen-size mini cylinder |
| Bore size | Ø10 mm |
| Rod diameter | Ø4 mm |
| Stroke | 25 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 (Ø10mm)
| Pressure | Net push force |
|---|---|
| 0.5 MPa | 29.8 N |
| 0.7 MPa (max) | 45.5 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 PSB10X25R Is Used
Part Ejection
Pushes finished metal stamps off a machining bed. The spring safely pulls the rod back when air is cut, preventing crashes.
Sorting Gate
Acts as a diverter arm on a packaging line. One air line extends the gate to route boxes, and the spring retracts it for straight pass-through.
Light Clamping
Holds a thin cardboard blank during folding. The fail-safe retract releases the part instantly if the main air supply fails.
Is the Airtac PSB Single Acting Compact Cylinder PSB10X25R the Right Cylinder?
This 10 mm bore yields 29.8 N net push at 0.5 MPa. Stepping down, a 6 mm bore offers 10.6 N, while a 12 mm bore provides 42.9 N. The internal spring sets a 0.2 MPa minimum pressure before the rod moves. Plan for a safe working load of about 18 N, which is roughly 60 percent of the 0.5 MPa rating, to account for seal friction.
The fixed TPU bumper decelerates the last few millimeters of travel but is not a lock. At higher speeds with real tooling mass, meter-out the exhaust or add an external shock absorber. Confirm your ordering essentials: 10 mm bore, 25 mm stroke, no magnet, R axial back cover, and your preferred 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 PSB10X25R FAQ
The net push force is 29.8 N at 0.5 MPa and 45.5 N at 0.7 MPa. The internal return spring requires a minimum of 0.2 MPa before the rod can extend. If air is lost, the spring pulls the rod back to the retracted position.
No. The thin 4 mm rod is designed for coaxial thrust, so add an external guide for off-axis loads. The fixed TPU bumper only cushions the final few millimeters of travel; it does not act as a brake or hold the rod in a mid-stroke position.
