Airtac PSB Single Acting Compact Cylinder PSB10X30SULB
The AirTAC Airtac PSB Single Acting Compact Cylinder PSB10X30SULB 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 PSB10X30SULB
The AirTAC PSB10X30SULB is a JIS pen-size single-acting push cylinder equipped with a built-in magnet, 90-degree side inlet, and LB mounting bracket. Air entering the single M5x0.8 port extends the Ø4 mm rod to deliver 29.8 N of net push at 0.5 MPa. When exhaust releases, an internal spring automatically retracts the rod, ensuring a fail-safe home position on air loss. This single-line operation simplifies valving and tubing compared to double-acting setups.
Built with a SUS304 stainless steel barrel and rod, the slim mini body resists corrosion in damp or tight jig environments. The piston features a fixed TPU bumper to decelerate motion at the end of stroke. Because the return spring creates opposing force, a minimum operating pressure of 0.2 MPa is required before movement begins. For practical sizing, plan for a safe working load of about 18 N, which accounts for roughly 60 percent of the rated 0.5 MPa force to ensure smooth travel against seal friction.

| Model | Airtac PSB Single Acting Compact Cylinder PSB10X30SULB |
|---|---|
| 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 PSB10X30SULB Is Used
Stamping Ejector
Pushes small stamped metal parts out of a die on a press line. The spring-return design guarantees the ejector clears the tooling when air is dropped for safety.
Package Diverter
Acts as a slim sorting gate on a packaging conveyor. The LB bracket secures the body firmly while the U side inlet keeps pneumatic plumbing flat against the machine frame.
Clamp Release
Applies 29.8 N of holding push at 0.5 MPa to secure light wooden workpieces on a CNC router. The single-acting spring automatically unclamps if the air supply fails.
Is the Airtac PSB Single Acting Compact Cylinder PSB10X30SULB the Right Cylinder?
This 10 mm bore provides 29.8 N net push at 0.5 MPa and 45.5 N at 0.7 MPa maximum pressure. If your application requires less force, stepping down to the Ø6 bore yields 10.6 N at 0.5 MPa. Conversely, moving up to the Ø12 bore increases output to 42.9 N at 0.5 MPa. Keep the fail-safe retract behavior in mind, as the spring holds the rod retracted without live air. Confirm your ordering essentials: 10 mm bore, 30 mm stroke, S magnet for electronic or reed switches, U side inlet, and LB mounting bracket.
The thin Ø4 mm rod is engineered strictly for coaxial thrust. Over this 30 mm stroke or under off-axis loads, add an external guide or linear bearing to prevent side-load damage. Additionally, the fixed TPU bumper only absorbs energy in the final few millimeters. At higher cycling 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 PSB10X30SULB FAQ
The net 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 operating pressure of 0.2 MPa is required before the rod begins to move. The spring also ensures the rod fails-safe retracted upon air loss.
The -S suffix indicates a built-in piston magnet compatible with AirTAC reed or electronic switches. For cushioning, it relies on a fixed TPU bumper at the ends rather than an adjustable shock. At high speeds with heavy tooling mass, you should meter-out the exhaust or add an external shock absorber since the bumper only decelerates the last few millimeters.
