Airtac PSB Single Acting Compact Cylinder PSB10X30SCB
The AirTAC Airtac PSB Single Acting Compact Cylinder PSB10X30SCB 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 PSB10X30SCB
The AirTAC PSB10X30SCB 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 ensures fail-safe retraction upon exhaust. This design simplifies valving and tubing to one solenoid line. It delivers 29.8 N of net push at 0.5 MPa and 45.5 N at 0.7 MPa, with the return spring force already deducted.
Built with a SUS304 stainless barrel and a CB double clevis for pivoting loads, this compact actuator includes a built-in piston magnet for position sensing. A fixed TPU bumper decelerates the stroke at each end. For smooth operation, plan for a safe working load of about 18 N, which accounts for roughly 60 percent of the theoretical force to overcome seal friction.
Airtac PSB Single Acting Compact Cylinder PSB10X30SCB Technical Specifications
| Model | Airtac PSB Single Acting Compact Cylinder PSB10X30SCB |
|---|---|
| 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 PSB10X30SCB Is Used
Part Ejection
Pushes finished metal parts out of a CNC machining fixture. The spring-return design guarantees the ejector retracts clear on air loss, preventing collisions with the next cycle.
Flap Folding
Extends to fold carton flaps on a packaging line. The CB double clevis allows the cylinder body to pivot smoothly as the flaps close, absorbing angular misalignment.
Diverter Gate
Acts as a spring-return diverter gate on a sorting conveyor. The single air line lowers tubing costs, and the fail-safe retract pulls the gate back to let standard traffic pass unobstructed.
Is the Airtac PSB Single Acting Compact Cylinder PSB10X30SCB the Right Cylinder?
When sizing this 10 mm bore model, compare its 29.8 N net push at 0.5 MPa with neighboring bores. Dropping to a 6 mm bore yields 10.6 N, while stepping up to a 12 mm bore provides 42.9 N. The internal return spring requires a minimum operating pressure of 0.2 MPa before the rod moves. The thin Ø4 mm rod is built for coaxial thrust, so over this 30 mm stroke or under off-axis loads, add an external guide or linear bearing to prevent side load damage.
Confirm your ordering essentials: 10 mm bore, 30 mm stroke, S for the piston magnet, CB double clevis inlet, and any mounting brackets. The CB clevis accommodates pivoting applications. With a 2:1 safety margin, this model safely lifts about 1.5 kg vertically. At higher cycling speeds with real tooling mass, the fixed TPU bumper may bottom out, so meter-out the exhaust or add an external shock absorber.
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 PSB10X30SCB 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 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 indicates a built-in piston magnet compatible with AirTAC reed or electronic switches. Cushioning is handled by a fixed TPU bumper at each end that decelerates the last few millimeters of travel; it is not adjustable and cannot hold an external load.
