Airtac PSB Single Acting Compact Cylinder PSB10X25U
The AirTAC Airtac PSB Single Acting Compact Cylinder PSB10X25U 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 PSB10X25U
The AirTAC PSB10X25U is a JIS pen-size single-acting push cylinder that extends its Ø4 mm rod via one M5x0.8 air line and relies on a built-in return spring to retract safely upon exhaust loss. Because the spring constantly opposes the air stroke, it yields a true usable output of 29.8 N net push at 0.5 MPa and 45.5 N at 0.7 MPa. The U suffix equips this 10 mm bore body with a 90-degree side inlet for flat plumbing in cramped spaces.
Its slim SUS304 stainless barrel and fixed TPU bumper suit damp, tight jigs where a single solenoid line cuts tubing complexity. The internal spring guarantees the rod parks retracted without live air, making it ideal for part ejection or clamp release. Plan for roughly 18 N of real work to account for seal friction, which translates to lifting about 1.5 kg vertically with a sane 2:1 margin.
Airtac PSB Single Acting Compact Cylinder PSB10X25U Technical Specifications
| Model | Airtac PSB Single Acting Compact Cylinder PSB10X25U |
|---|---|
| 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 PSB10X25U Is Used
Stamping Ejector
Pushes small stamped parts out of a die on signal, and the spring safely pulls the pin back when air drops so the press can reload without jamming.
Package Diverter
Briefly extends a 25 mm stroke gate to deflect lightweight cartons on a packaging line, using the 90-degree side inlet to keep the manifold tucked away.
Clamp Release
Applies 29.8 N of hold-down force at 0.5 MPa to secure a thin workpiece, automatically releasing the part if the compressed air supply fails.
Is the Airtac PSB Single Acting Compact Cylinder PSB10X25U the Right Cylinder?
This 10 mm bore provides 29.8 N net push at 0.5 MPa; sizing down to a Ø6 gives just 10.6 N, while stepping up to a Ø12 yields 42.9 N for heavier duty. A minimum 0.2 MPa is required before the rod overcomes the return spring and moves. Confirm your ordering essentials: 10 mm bore, 25 mm stroke, U side inlet, and no magnet (S omitted).
The thin Ø4 mm rod handles coaxial thrust well but needs an external guide or linear bearing if subjected to off-axis loads over its 25 mm stroke. Since the fixed TPU bumper only decelerates the final few millimeters, meter-out the exhaust or add an external shock absorber when cycling real tooling mass at high speeds.
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 PSB10X25U FAQ
It delivers 29.8 N net push at 0.5 MPa and 45.5 N at 0.7 MPa maximum. A minimum of 0.2 MPa is required to overcome the internal return spring; without live air, the spring holds the rod fail-safe retracted.
The U suffix designates a 90-degree side air inlet for tight mounting. Cushioning is handled by a fixed TPU bumper that decelerates the rod over the last few millimeters; it is not adjustable, so add an external shock absorber for heavy tooling mass.
