Airtac PSB Single Acting Compact Cylinder PSB10X20U
The AirTAC Airtac PSB Single Acting Compact Cylinder PSB10X20U is a single acting, push type (spring return) pen-size mini cylinder with a Ø10mm bore and 20mm 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 PSB10X20U
The AirTAC PSB10X20U is a JIS pen-size single-acting push cylinder, meaning air entering its single M5x0.8 port extends the rod while an internal spring retracts it. This fail-safe design ensures the rod pulls back home if air pressure drops, making it ideal for part ejection and clamp-release tasks. It supplies 29.8 N of net push at 0.5 MPa.
Built with a SUS304 stainless barrel and a slim body, it fits easily into tight machinery. The U suffix indicates a 90-degree side inlet for flat plumbing. A fixed TPU bumper cushions the stroke ends. For reliable operation, plan for a safe working load of about 18 N, which accounts for friction and smooth travel.
Airtac PSB Single Acting Compact Cylinder PSB10X20U Technical Specifications
| Model | Airtac PSB Single Acting Compact Cylinder PSB10X20U |
|---|---|
| Series | PSB JIS pen-size mini cylinder |
| Bore size | Ø10 mm |
| Rod diameter | Ø4 mm |
| Stroke | 20 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 PSB10X20U Is Used
Part Ejector
Pushes finished lightweight plastic parts off a conveyor belt, with the spring ensuring the arm retracts safely when air stops.
Clamp Release
Acts as a fail-safe clamp release on a CNC fixture, holding position under air and withdrawing automatically on pressure loss.
Flap Folder
Folds small cardboard flaps on a packaging line, utilizing the compact pen-size body to fit within tight machine guarding.
Is the Airtac PSB Single Acting Compact Cylinder PSB10X20U the Right Cylinder?
This 10 mm bore generates 29.8 N net push at 0.5 MPa. If you need less force, the Ø6 bore offers 10.6 N; for heavier tasks, the Ø12 bore provides 42.9 N. Remember the internal spring sets a 0.2 MPa minimum pressure before motion begins. The thin Ø4 mm rod handles coaxial thrust well, but over long strokes or off-axis loads, add an external guide or linear bearing to prevent side-load damage.
When ordering, confirm the 10 mm bore, 20 mm stroke, and the U 90-degree side inlet. This specific unit lacks a sensor magnet. Mounting requires compatible AirTAC PB brackets like LB, FA, or CJ.
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 PSB10X20U FAQ
It delivers 29.8 N net push at 0.5 MPa and 45.5 N at 0.7 MPa maximum. Because an internal spring returns the rod, a minimum pressure of 0.2 MPa is required before the piston moves.
It uses a fixed TPU bumper at each end to decelerate the stroke over the last few millimeters. This bumper is not adjustable or a locking brake, so at higher speeds with real tooling mass, meter-out the exhaust or add an external shock absorber.
