Airtac PSB Single Acting Compact Cylinder PSB10X30U
The AirTAC Airtac PSB Single Acting Compact Cylinder PSB10X30U is a single acting, push type (spring return) pen-size mini cylinder with a Ø10mm bore and 30mm 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 PSB10X30U
The AirTAC PSB10X30U is a JIS pen-size single-acting push cylinder that extends via one M5x0.8 air port and retracts via an internal spring. It provides 29.8 N of net push force at 0.5 MPa, climbing to 45.5 N at the 0.7 MPa maximum. The U suffix designates a 90-degree side inlet for flat plumbing in confined spaces.
Built with a SUS304 stainless rod and barrel, this slim mini body resists corrosion in damp jigs. The fail-safe spring ensures the rod pulls home on air loss, making it ideal for clamp-release tasks. A fixed TPU bumper cushions the stroke ends, and the M8x1.0 rod-end thread handles standard tooling mounts.
Airtac PSB Single Acting Compact Cylinder PSB10X30U Technical Specifications
| Model | Airtac PSB Single Acting Compact Cylinder PSB10X30U |
|---|---|
| Series | PSB JIS pen-size mini cylinder |
| Bore size | Ø10 mm |
| Rod diameter | Ø4 mm |
| Stroke | 30 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 PSB10X30U Is Used
Part Ejector
Pushes finished plastic parts off an injection mold platen. The spring retract guarantees the ejector pin clears the mold when air drops.
Gate Diverter
Acts as a sorting gate on a packaging conveyor. The 90-degree side inlet keeps the hose profile flat against the machine frame.
Clamp Release
Holds a lightweight aluminum workpiece against a machining stop. Air loss automatically retracts the clamp for safe clearing.
Is the Airtac PSB Single Acting Compact Cylinder PSB10X30U the Right Cylinder?
This 10 mm bore yields 29.8 N net push at 0.5 MPa. Stepping down, the Ø6 generates 10.6 N, while stepping up to the Ø12 provides 42.9 N. Plan for a safe working load of roughly 18 N, which accounts for seal friction at 60 percent of the rated force. The internal spring sets a 0.2 MPa minimum pressure before motion begins.
For vertical lifts, expect to raise about 1.5 kg safely with a 2:1 margin. The thin Ø4 mm rod handles coaxial thrust well but needs an external guide for off-axis loads. To order, confirm the 30 mm stroke, the U side inlet, your mounting bracket, and whether you need the S magnet variant for reed or electronic switches.
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 PSB10X30U FAQ
The net usable push force is 29.8 N at 0.5 MPa and 45.5 N at the 0.7 MPa maximum. Because the internal return spring opposes the air stroke, a minimum of 0.2 MPa is required before the rod extends.
It uses a fixed TPU bumper at each end to decelerate the last few millimeters of travel. The bumper is not adjustable. At high speeds with heavy tooling mass, meter-out the exhaust or add an external shock absorber to prevent bottoming out.
