Airtac PSB Single Acting Compact Cylinder PSB10X25CB
The AirTAC Airtac PSB Single Acting Compact Cylinder PSB10X25CB 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 PSB10X25CB
The AirTAC PSB10X25CB is a JIS pen-size single-acting push cylinder with a 10 mm bore and 25 mm stroke. Air entering the single M5x0.8 port extends the Ø4 mm rod, while an internal spring brings it back upon exhaust release. This fail-safe design ensures the rod retracts automatically if air pressure drops. It delivers 29.8 N of net push at 0.5 MPa and 45.5 N at 0.7 MPa.
Featuring a CB double clevis back cover for pivoting loads, this slim SUS304 stainless steel body fits easily into tight jigs. A fixed TPU bumper decelerates the stroke at both ends. For reliable operation, plan for a safe working load of roughly 18 N, which accounts for seal friction and smooth travel.
Airtac PSB Single Acting Compact Cylinder PSB10X25CB Technical Specifications
| Model | Airtac PSB Single Acting Compact Cylinder PSB10X25CB |
|---|---|
| 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 PSB10X25CB Is Used
CNC Part Ejector
Pushes machined aluminum plugs out of a lathe collet using 29.8 N of force, with the spring ensuring the ejector retracts clear of the spindle during loading.
Package Diverter Gate
Extends a lightweight deflector flap to route small cartons on a packaging line, relying on the CB double clevis to pivot smoothly as air cycles on and off.
Clamp Release Mechanism
Holds a wooden workpiece against a router fence under spring pressure, automatically releasing the part safely if the main air supply suddenly fails.
Is the Airtac PSB Single Acting Compact Cylinder PSB10X25CB the Right Cylinder?
This 10 mm bore model yields 29.8 N net push at 0.5 MPa. If your task needs less force, the Ø6 variant supplies 10.6 N under the same pressure; for heavier jobs, the Ø12 bore offers 42.9 N. Remember the internal spring sets a 0.2 MPa minimum pressure before motion starts. The CB double clevis inlet accommodates pivoting linkages perfectly.
When ordering, verify the 25 mm stroke, the lack of a sensor magnet, and the CB clevis back cover. The slender Ø4 mm rod handles coaxial thrust well, but over long strokes or off-axis loads, add an external 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 PSB10X25CB FAQ
It provides a net push of 29.8 N at 0.5 MPa and 45.5 N at 0.7 MPa. Because an internal spring returns the rod, a minimum operating pressure of 0.2 MPa is required before the piston moves. The rod fails safe to the retracted position on air loss.
It uses a fixed TPU bumper at the ends to decelerate the stroke over the last few millimeters. The bumper is not adjustable. At higher speeds with real tooling mass, you should meter-out the exhaust or add an external shock absorber to prevent bottoming out.
