Airtac PSB Single Acting Compact Cylinder PSB10X45SR
The AirTAC Airtac PSB Single Acting Compact Cylinder PSB10X45SR is a single acting, push type (spring return) pen-size mini cylinder with a Ø10mm bore and 45mm 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 PSB10X45SR
The AirTAC PSB10X45SR is a JIS pen-size single-acting push cylinder that extends its 4 mm rod via one M5x0.8 air port, while an internal spring handles the retraction. This design cuts tubing and valving complexity down to a single solenoid line. You get 29.8 N of usable push at 0.5 MPa and 45.5 N at the 0.7 MPa maximum, with the return spring force already subtracted from these figures.
Built with a SUS304 stainless barrel and a slim profile, it fits easily into cramped jigs and end-of-arm tooling. The built-in magnet (-S) supports reed or electronic switches for position confirmation, and the R axial inlet keeps plumbing neatly in line. A fixed TPU bumper cushions the stroke ends.
Airtac PSB Single Acting Compact Cylinder PSB10X45SR Technical Specifications
| Model | Airtac PSB Single Acting Compact Cylinder PSB10X45SR |
|---|---|
| Series | PSB JIS pen-size mini cylinder |
| Bore size | Ø10 mm |
| Rod diameter | Ø4 mm |
| Stroke | 45 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 PSB10X45SR Is Used
Stamping Ejector
Pushes small stamped parts out of a die on a press line, using the spring-return to safely retract the pin when air is cut.
Package Diverter
Acts as a slim sorting gate on a packaging conveyor, extending to deflect lightweight cartons and springing back to clear the path.
Lab Sample Clamp
Holds a test vial securely in a testing fixture, providing a reliable 29.8 N push at 0.5 MPa without needing continuous power to retract.
Is the Airtac PSB Single Acting Compact Cylinder PSB10X45SR the Right Cylinder?
This 10 mm bore generates 29.8 N net push at 0.5 MPa. Stepping down to a 6 mm bore yields 10.6 N, whereas moving up to a 12 mm bore provides 42.9 N. Plan for a safe working load of roughly 18 N, which is about 60 percent of the 0.5 MPa rating, to account for seal friction. You can also lift about 1.5 kg vertically with a sane 2:1 safety margin.
The internal return spring makes the rod fail-safe retracted upon air loss, ideal for part ejection, but it also dictates a 0.2 MPa minimum pressure before motion begins. Because the 4 mm rod is slender over a 45 mm stroke, add an external linear bearing for any off-axis loads. To order, confirm the 10 mm bore, 45 mm stroke, S magnet, R axial inlet, 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 PSB10X45SR FAQ
It provides a net push of 29.8 N at 0.5 MPa and 45.5 N at 0.7 MPa, with the spring force already deducted. A minimum of 0.2 MPa is required to overcome the return spring and extend the rod.
The -S suffix indicates a built-in piston magnet for use with reed or electronic switches. Cushioning is handled by a fixed TPU bumper at each end, which decelerates the last few millimeters of travel but may require external shock absorption at high speeds.
