Airtac PSB Single Acting Compact Cylinder PSB16X30SU
The AirTAC Airtac PSB Single Acting Compact Cylinder PSB16X30SU is a single acting, push type (spring return) pen-size mini cylinder with a Ø16mm 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 PSB16X30SU
The AirTAC PSB16X30SU is a JIS pen-size single-acting push cylinder that extends via air pressure and retracts via an internal spring. It provides 74.8 N of net push at 0.5 MPa and 115 N at 0.7 MPa. Because the spring force is already subtracted, these are your true usable thrust figures. The fail-safe design ensures the rod pulls home automatically upon air loss.
This variant includes a built-in piston magnet for position sensing and a U-style 90-degree side air inlet for flat plumbing. The SUS304 stainless barrel and slim body fit tight jigs. It connects via an M5x0.8 port and features a fixed TPU bumper that decelerates the stroke at each end.
Airtac PSB Single Acting Compact Cylinder PSB16X30SU Technical Specifications
| Model | Airtac PSB Single Acting Compact Cylinder PSB16X30SU |
|---|---|
| Series | PSB JIS pen-size mini cylinder |
| Bore size | Ø16 mm |
| Rod diameter | Ø5 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 (Ø16mm)
| Pressure | Net push force |
|---|---|
| 0.5 MPa | 74.8 N |
| 0.7 MPa (max) | 115.0 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 PSB16X30SU Is Used
Part Ejection
Pushes finished metal stamps out of a press die, using the spring retract to clear the workspace safely during air cuts.
Sorting Gate
Deflects packages on a high-speed line; the fail-safe retract opens the lane automatically if pneumatic pressure drops.
Flap Folder
Tucks carton flaps during case erecting, fitting into cramped end-of-arm tooling via the 90-degree side inlet.
Is the Airtac PSB Single Acting Compact Cylinder PSB16X30SU the Right Cylinder?
At 0.5 MPa this 16 mm bore yields 74.8 N of net push. If you need less force, stepping down to the 12 mm bore gives 42.9 N. Since 16 mm is the largest pen-size option, moving beyond 115 N at 0.7 MPa requires switching to a larger non-pen series. Plan for a safe working load of roughly 45 N, which is about 60 percent of the 0.5 MPa rating, to account for seal friction.
The internal spring sets a 0.2 MPa minimum pressure before motion begins. The thin Ø5 mm rod handles coaxial thrust well but needs an external guide for off-axis loads. When ordering, confirm the 30 mm stroke, the S magnet, the U side inlet, and your mounting bracket.
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 PSB16X30SU FAQ
The net push force is 74.8 N at 0.5 MPa and 115 N at 0.7 MPa. The internal return spring requires a minimum of 0.2 MPa to extend the rod.
It uses a fixed TPU bumper to decelerate the last few millimeters of travel; at high speeds with heavy tooling, meter-out the exhaust. The S suffix denotes a piston magnet compatible with reed or electronic switches.
