Airtac PSB Single Acting Compact Cylinder PSB16X5U
The AirTAC Airtac PSB Single Acting Compact Cylinder PSB16X5U 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 PSB16X5U
The AirTAC PSB16X5U is a JIS pen-size single-acting push cylinder with a 5 mm stroke. Air entering the single M5x0.8 port extends the Ø5 mm rod, while an internal spring retracts it upon exhaust release. This fail-safe design ensures the rod returns home if air pressure drops, making it ideal for clamp-release or part-eject duties. The U suffix designates a 90-degree side inlet for flat plumbing in tight spaces.
It delivers 74.8 N of net push at 0.5 MPa and 115 N at the 0.7 MPa maximum, with the return spring force already deducted. The SUS304 stainless barrel and slim mini body resist corrosion in damp environments. A fixed TPU bumper at each end decelerates the stroke over the last few millimeters. Plan for a safe working load of about 45 N, which accounts for seal friction and smooth travel.
Airtac PSB Single Acting Compact Cylinder PSB16X5U Technical Specifications
| Model | Airtac PSB Single Acting Compact Cylinder PSB16X5U |
|---|---|
| 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 PSB16X5U Is Used
Short-Stroke Clamping
Applies 74.8 N of net push at 0.5 MPa to hold light aluminum housings during a machining pass, releasing instantly when air is removed.
Part Diverter Gate
Uses the 5 mm stroke to push small plastic bottles across a packaging line, with the spring ensuring the gate retracts on air loss to clear the belt.
Ejector Pins
Ejects finished stamped components from a tight die jig, leveraging the 90-degree side inlet to keep plumbing flush against the machine frame.
Is the Airtac PSB Single Acting Compact Cylinder PSB16X5U the Right Cylinder?
This 16 mm bore provides the highest net push in the PSB family at 74.8 N (0.5 MPa). If your task requires less force, stepping down to the 12 mm bore yields 42.9 N under the same pressure. Because 16 mm is the largest available pen-size option, applications needing more than 115 N at 0.7 MPa require a larger non-pen cylinder. The internal return spring sets a 0.2 MPa minimum operating pressure before motion begins.
Confirm your ordering essentials: 16 mm bore, 5 mm stroke, U 90-degree side inlet, and no magnet (S). The M10x1.0 rod-end thread and M5x0.8 port are fixed by the bore size. Since the rod is only Ø5 mm, use an external guide or linear bearing for any off-axis loads to prevent bending.
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 PSB16X5U FAQ
The net push force is 74.8 N at 0.5 MPa and 115 N at the 0.7 MPa maximum. The internal return spring requires a minimum operating pressure of 0.2 MPa before the rod can extend, and the rod fails safe to the retracted position on air loss.
The U suffix indicates a 90-degree side air inlet for flat mounting. It uses a fixed TPU bumper at each end to decelerate the stroke over the final few millimeters. Because the bumper is not adjustable, you should meter-out the exhaust or add an external shock absorber when cycling heavy tooling at high speeds.
