Airtac PSB Single Acting Compact Cylinder PSB16X60U
The AirTAC Airtac PSB Single Acting Compact Cylinder PSB16X60U is a single acting, push type (spring return) pen-size mini cylinder with a Ø16mm bore and 60mm 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 PSB16X60U
The AirTAC PSB16X60U is a JIS pen-size single-acting push cylinder with a 60 mm stroke. Air entering the single M5x0.8 port extends the Ø5 mm rod, while an internal spring ensures a fail-safe retracted state upon air loss. This configuration requires only one solenoid line, simplifying tubing and reducing valving costs. 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 U suffix indicates a 90-degree side inlet for flat plumbing in confined spaces. Built with a SUS304 stainless steel barrel and rod, the slim mini body resists corrosion in damp jigs. A fixed TPU bumper at each end decelerates the stroke, though at high speeds with real tooling mass you should meter-out the exhaust or add an external shock absorber. Plan for a safe working load of about 45 N (roughly 60% of the 0.5 MPa figure) to account for seal friction.
Airtac PSB Single Acting Compact Cylinder PSB16X60U Technical Specifications
| Model | Airtac PSB Single Acting Compact Cylinder PSB16X60U |
|---|---|
| Series | PSB JIS pen-size mini cylinder |
| Bore size | Ø16 mm |
| Rod diameter | Ø5 mm |
| Stroke | 60 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 PSB16X60U Is Used
Part Ejection
Pushes machined components off a conveyor belt. The spring-return design guarantees the ejector arm clears the workspace if the air supply drops.
Clamp Release
Applies 74.8 N of holding push at 0.5 MPa for light machining fixtures. The single-acting design automatically retracts the clamp safely during an air failure.
Flap Folder
Extends to fold carton flaps on a packaging line. The 90-degree side inlet keeps the plumbing flush against the machine frame to save space.
Is the Airtac PSB Single Acting Compact Cylinder PSB16X60U the Right Cylinder?
This 16 mm bore provides the strongest push in the series, yielding 74.8 N at 0.5 MPa. If your application requires less force, stepping down to a 12 mm bore drops the net push to 42.9 N, which may better suit lighter ejectors. Because 16 mm is the largest available pen-size option, heavier duty tasks beyond 115 N at 0.7 MPa require a different cylinder family entirely.
Keep in mind the internal spring sets a 0.2 MPa minimum pressure before motion begins, and the rod defaults to a safe retracted position on air loss. The slim Ø5 mm rod handles coaxial thrust well, but over the full 60 mm stroke or under off-axis loads, add an external linear bearing to prevent side-load damage. Confirm your ordering essentials: 16 mm bore, 60 mm stroke, no 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 PSB16X60U 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 dictates a 0.2 MPa minimum operating pressure before the rod extends, and the cylinder fails safely to a retracted position on air loss.
This model uses a fixed TPU bumper at each end to decelerate the last few millimeters of travel; it is not an adjustable cushion or a locking brake. At high speeds with heavy tooling, meter-out the exhaust or add an external shock absorber. This specific SKU does not include a sensor magnet.
