Airtac PSB Single Acting Compact Cylinder PSB10X20R
The AirTAC Airtac PSB Single Acting Compact Cylinder PSB10X20R 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 PSB10X20R
The AirTAC PSB10X20R is a JIS pen-size single-acting push cylinder, meaning air entering the M5x0.8 port extends the Ø4 mm rod while an internal spring retracts it upon exhaust release. This single-line operation simplifies valving and tubing while ensuring the rod fails safe to the retracted position if air pressure drops. It provides 29.8 N of net push force at 0.5 MPa.
Built with a SUS304 stainless barrel and slim body, it fits easily into tight jigs and light end-of-arm tooling. The bore uses a fixed TPU bumper at each end to decelerate motion in the final few millimeters. Plan for a safe working load of about 18 N, which is roughly 60 percent of the 0.5 MPa rating, to account for seal friction and smooth travel.
Airtac PSB Single Acting Compact Cylinder PSB10X20R Technical Specifications
| Model | Airtac PSB Single Acting Compact Cylinder PSB10X20R |
|---|---|
| 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 PSB10X20R Is Used
Part Ejector
Pushes machined pins out of a fixture on a lathe; the spring safely pulls the ejector pin back when air is removed to clear the workspace.
Diverter Gate
Extends a lightweight deflector plate to route small plastic parts down a packaging line, relying on single-line plumbing for simple control.
Flap Tucker
Folds carton side flaps prior to sealing, using the compact stainless body to fit within narrow conveyor side frames.
Is the Airtac PSB Single Acting Compact Cylinder PSB10X20R the Right Cylinder?
This 10 mm bore with a 20 mm stroke yields 29.8 N net push at 0.5 MPa. If your task needs less force, stepping down to the Ø6 bore gives 10.6 N at the same pressure. If you require more thrust, moving up to the Ø12 bore provides 42.9 N. Remember the internal spring sets a 0.2 MPa minimum pressure before the rod will move. Confirm your ordering essentials: 10 mm bore, 20 mm stroke, no magnet, R axial back cover, and any LB, FA, or CJ mount brackets.
Because the rod is only 4 mm thick, it is designed strictly for coaxial thrust. Over this 20 mm stroke, avoid side loads by adding an external guide or linear bearing for any off-axis tooling mass. The fixed TPU bumper handles light end-of-stroke damping, but at higher cycling speeds with real mass, 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 PSB10X20R 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 before the piston can extend.
Air drives the rod out through the M5x0.8 port, and exhausting the air lets the spring retract it. This 10 mm bore includes a fixed TPU bumper to cushion the last few millimeters of travel, but it is not an adjustable shock or a locking brake for external loads.
