Airtac PSB Single Acting Compact Cylinder PSB10X30SR
The AirTAC Airtac PSB Single Acting Compact Cylinder PSB10X30SR 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 PSB10X30SR
The AirTAC PSB10X30SR is a JIS pen-size single-acting push cylinder with a 10 mm bore and 30 mm stroke. Air entering the single M5x0.8 port extends the Ø4 mm rod, while an internal spring retracts it upon exhaust release. This design requires only one solenoid line, simplifying tubing and reducing valving costs. The fail-safe spring ensures the rod returns home if air pressure drops. It delivers 29.8 N of net push at 0.5 MPa and 45.5 N at 0.7 MPa.
Built with a SUS304 stainless barrel and slim mini body, it fits tight jigs and light end-of-arm tooling. The -S suffix denotes a built-in piston magnet for position sensing with reed or electronic switches. A fixed TPU bumper at each end decelerates the stroke over the final few millimeters. For smooth operation, plan for a safe working load of about 18 N, which accounts for seal friction at 60 percent of the 0.5 MPa rating.
Airtac PSB Single Acting Compact Cylinder PSB10X30SR Technical Specifications
| Model | Airtac PSB Single Acting Compact Cylinder PSB10X30SR |
|---|---|
| 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 PSB10X30SR Is Used
Component Ejection
Pushes finished machined parts out of a CNC fixture, relying on the spring to safely retract the ejector pin when air is removed.
Carton Flap Folding
Extends to fold small cardboard flaps on a packing line, with the single air line keeping pneumatic wiring minimal.
Sorter Diverter
Acts as a lightweight gate pusher on a conveyor, using the 29.8 N force to nudge lightweight product boxes onto a bypass lane.
Is the Airtac PSB Single Acting Compact Cylinder PSB10X30SR the Right Cylinder?
This 10 mm bore provides 29.8 N net push at 0.5 MPa. Stepping down to a 6 mm bore yields 10.6 N, while moving up to a 12 mm bore offers 42.9 N. The internal return spring sets a 0.2 MPa minimum pressure before motion begins. With a 2:1 safety margin, this model lifts about 1.5 kg vertically. The thin Ø4 mm rod handles coaxial thrust well, but over this 30 mm stroke or under off-axis loads, add an external linear guide to prevent side-loading damage.
When ordering, confirm the 10 mm bore, 30 mm stroke, -S magnet for switches, and R axial back cover inlet. The fixed TPU bumper is non-adjustable; at high speeds with real tooling mass, meter-out the exhaust or install an external shock absorber to prevent bottoming out.
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 PSB10X30SR FAQ
The net push force is 29.8 N at 0.5 MPa and 45.5 N at the 0.7 MPa maximum. Because an internal spring returns the rod, a minimum operating pressure of 0.2 MPa is required to overcome the spring and extend the cylinder.
The -S suffix means a built-in magnet works with reed or electronic switches for end-of-stroke detection. Cushioning relies on a fixed TPU bumper at each end that absorbs impact over the last few millimeters; it is non-adjustable and not a braking mechanism for external loads.
