Airtac PSB Single Acting Compact Cylinder PSB16X5SU
The AirTAC Airtac PSB Single Acting Compact Cylinder PSB16X5SU is a single acting, push type (spring return) pen-size mini cylinder with a Ø16mm bore and 5mm 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 PSB16X5SU
The AirTAC PSB16X5SU is a JIS pen-size single-acting push cylinder that extends its Ø5 mm rod via one M5x0.8 air line, relying on an internal spring to retract safely on exhaust. It supplies 74.8 N of net push at 0.5 MPa and 115 N at the 0.7 MPa maximum. The U suffix designates a 90-degree side inlet for flat plumbing, while the S suffix adds a piston magnet for position sensing.
Built with a SUS304 stainless barrel and a slim mini body, it fits tight jigs and light end-of-arm tooling. A fixed TPU bumper decelerates the stroke near the ends. For a practical safety margin, plan for roughly 45 N of real work (about 60 percent of the 0.5 MPa rating). This equates to lifting around 3.8 kg vertically with a 2:1 load factor.
Airtac PSB Single Acting Compact Cylinder PSB16X5SU Technical Specifications
| Model | Airtac PSB Single Acting Compact Cylinder PSB16X5SU |
|---|---|
| Series | PSB JIS pen-size mini cylinder |
| Bore size | Ø16 mm |
| Rod diameter | Ø5 mm |
| Stroke | 5 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 PSB16X5SU Is Used
Part Ejection
Pushes stamped metal blanks off a conveyor belt. The spring-return design guarantees the ejector arm pulls back safely when air is cut.
Flap Folding
Extends to fold carton flaps on a packaging line. The 90-degree side inlet keeps plumbing flush against the machine frame.
Clamp Release
Acts as a fail-safe clamp release on an assembly fixture, automatically retracting the Ø5 mm rod to free the part during an air loss event.
Is the Airtac PSB Single Acting Compact Cylinder PSB16X5SU the Right Cylinder?
This 16 mm bore yields 74.8 N net push at 0.5 MPa, sitting at the top of the PSB range; dropping to a 12 mm bore reduces usable force to 42.9 N. The internal return spring demands a minimum 0.2 MPa to overcome its bias before motion begins, ensuring the rod stays retracted if air pressure drops. Confirm your ordering essentials: 5 mm stroke, built-in magnet (S), 90-degree side inlet (U), and your preferred mounting bracket.
Because the thin Ø5 mm rod handles coaxial thrust rather than side loading, add an external linear bearing if your application involves off-axis forces. The fixed TPU bumper only absorbs impact over the final few millimeters, so meter-out the exhaust or install an external shock absorber when cycling heavy tooling at high speeds.
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 PSB16X5SU FAQ
It provides 74.8 N of net push at 0.5 MPa and 115 N at 0.7 MPa (maximum). Because the internal spring opposes the air stroke, a minimum pressure of 0.2 MPa is required before the rod extends.
Yes. The S suffix indicates a built-in piston magnet that is compatible with AirTAC reed or electronic solid-state switches for precise position detection.
