Airtac PSB Single Acting Compact Cylinder PSB16X25SU
The AirTAC Airtac PSB Single Acting Compact Cylinder PSB16X25SU is a single acting, push type (spring return) pen-size mini cylinder with a Ø16mm bore and 25mm 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 PSB16X25SU
The AirTAC PSB16X25SU is a JIS pen-size single-acting push cylinder that extends its Ø5 mm rod via one M5x0.8 air line and relies on an internal spring to retract. Because the spring counteracts the air stroke, you get 74.8 N of net push at 0.5 MPa and 115 N at the 0.7 MPa maximum. The U suffix adds a 90-degree side inlet for flat plumbing, while the S suffix provides a built-in magnet for position sensing.
Built with a SUS304 stainless barrel and slim body, it fits tight spaces and damp jigs. A fixed TPU bumper cushions the stroke ends. Plan for a safe working load of about 45 N, which is roughly 60 percent of the 0.5 MPa figure, to account for seal friction. If lifting vertically, expect to handle around 3.8 kg with a sane 2:1 margin.
Airtac PSB Single Acting Compact Cylinder PSB16X25SU Technical Specifications
| Model | Airtac PSB Single Acting Compact Cylinder PSB16X25SU |
|---|---|
| Series | PSB JIS pen-size mini cylinder |
| Bore size | Ø16 mm |
| Rod diameter | Ø5 mm |
| Stroke | 25 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 PSB16X25SU Is Used
Stamping Ejector
Pushes finished metal blanks out of a press die using a single air line, with the spring safely pulling the pin back when air is cut.
Package Diverter
Acts as a slim routing gate on a packaging conveyor, extending to push cartons onto a side lane and retracting flush to let main traffic pass.
Clamp Release
Holds a workpiece by extending against it; removing air pressure lets the spring instantly release the clamp for quick part changes.
Is the Airtac PSB Single Acting Compact Cylinder PSB16X25SU the Right Cylinder?
This 16 mm bore provides the highest net push in the series at 74.8 N (0.5 MPa). If you need less force, the 12 mm bore yields 42.9 N under the same pressure. Since 16 mm is the largest available, heavier demands require a different body style entirely. The internal spring demands a minimum of 0.2 MPa before motion begins, and dropping air pressure fails-safely retracts the rod home. Confirm your ordering essentials: 16 mm bore, 25 mm stroke, S magnet, U side inlet, and your preferred 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 PSB16X25SU FAQ
It delivers a net push of 74.8 N at 0.5 MPa and 115 N at the 0.7 MPa maximum. The internal return spring requires at least 0.2 MPa before the rod can extend, and the cylinder fails-safe to a retracted position upon air loss.
Cushioning is fixed via non-adjustable TPU bumpers at both ends; for high-speed tooling mass, meter-out the exhaust or add an external shock absorber. The S suffix includes a piston magnet compatible with AirTAC reed or electronic solid-state switches.
