Airtac PSB Single Acting Compact Cylinder PSB10X30R
The AirTAC Airtac PSB Single Acting Compact Cylinder PSB10X30R 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 PSB10X30R
The AirTAC PSB10X30R is a JIS pen-size single-acting push cylinder with a 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 single-line design cuts tubing and solenoid costs while ensuring the rod fails safe to the retracted home position if air pressure drops. The SUS304 stainless barrel and slim body fit easily into tight jigs.
It provides 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 from these usable figures. A fixed TPU bumper cushions the stroke ends, and the R axial inlet keeps plumbing perfectly in line. Plan for a safe working load of about 18 N, which accounts for seal friction and smooth travel.
Airtac PSB Single Acting Compact Cylinder PSB10X30R Technical Specifications
| Model | Airtac PSB Single Acting Compact Cylinder PSB10X30R |
|---|---|
| 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 PSB10X30R Is Used
Part Ejector
Pushes finished plastic parts off a conveyor belt; the spring safely retracts the pin clear of the belt when air is removed.
Clamp Release
Actuates a temporary hold-down clamp on a machining fixture, saving wiring complexity with one solenoid line.
Flap Folder
Tucks carton flaps on a packaging line, where the fail-safe retract prevents jamming if the air supply suddenly stops.
Is the Airtac PSB Single Acting Compact Cylinder PSB10X30R the Right Cylinder?
This 10 mm bore generates 29.8 N net push at 0.5 MPa. If your task needs less force, the Ø6 bore offers 10.6 N; for heavier pushing, step up to the Ø12 bore providing 42.9 N. The internal spring requires a minimum 0.2 MPa operating pressure before the rod will move, and it actively holds the rod retracted without live air. Confirm your ordering essentials: 10 mm bore, 30 mm stroke, no magnet, R axial back cover, and standard mounting.
Because the rod is only Ø4 mm, use an external guide or linear bearing for any off-axis loads over this 30 mm stroke. The fixed TPU bumper only decelerates the last few millimeters, so meter-out the exhaust or add an external shock absorber if cycling at high speed with real tooling mass.
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 PSB10X30R FAQ
The net push force is 29.8 N at 0.5 MPa and 45.5 N at 0.7 MPa. The internal return spring dictates a minimum operating pressure of 0.2 MPa before the rod extends. Maximum operating pressure is 0.7 MPa.
Air extends the rod while a spring retracts it. A fixed TPU bumper at each end cushions the last few millimeters of travel. It is not adjustable, so for high-speed cycles with heavy tooling, use meter-out flow control or an external shock absorber.
