Airtac PSB Single Acting Compact Cylinder PSB16X30U
The AirTAC Airtac PSB Single Acting Compact Cylinder PSB16X30U 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 PSB16X30U
The AirTAC PSB16X30U is a 16 mm bore, 30 mm stroke single-acting push cylinder. Air entering the M5x0.8 port extends the rod, while an internal spring retracts it on exhaust. This fail-safe design ensures the rod returns home if air pressure drops. You get 74.8 N of net push at 0.5 MPa, or 115 N at the 0.7 MPa maximum.
The U suffix indicates a 90-degree side inlet for flat plumbing in tight spaces. The SUS304 stainless barrel and slim body suit damp or confined jigs. A fixed TPU bumper cushions the stroke ends. For smooth operation, plan for a safe working load of about 45 N, which accounts for seal friction.
Airtac PSB Single Acting Compact Cylinder PSB16X30U Technical Specifications
| Model | Airtac PSB Single Acting Compact Cylinder PSB16X30U |
|---|---|
| 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 PSB16X30U Is Used
Part Ejection
Pushes finished metal parts off a machining center conveyor. The fail-safe spring retract clears the workspace if air supply halts.
Flap Folding
Extends to fold carton flaps on a packaging line. The 90-degree side inlet keeps the cylinder profile flat against the machine frame.
Diverter Gate
Acts as a push diverter to route small boxes down a side lane. The 115 N force at 0.7 MPa handles rigid cardboard easily.
Is the Airtac PSB Single Acting Compact Cylinder PSB16X30U the Right Cylinder?
This 16 mm bore provides the maximum push in the PSB range. If your task needs less force, the 12 mm bore offers 42.9 N at 0.5 MPa. The internal return spring requires a minimum of 0.2 MPa before the rod moves. The thin 5 mm rod handles coaxial thrust, so add an external guide for any off-axis loads.
Confirm your ordering essentials: 16 mm bore, 30 mm stroke, no magnet, U side inlet, and your preferred mounting bracket. The fixed TPU bumper only decelerates the last few millimeters, so meter-out the exhaust if moving heavy tooling mass.
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 PSB16X30U FAQ
The net push force is 74.8 N at 0.5 MPa and 115 N at 0.7 MPa. The internal return spring sets a 0.2 MPa minimum pressure before the rod moves. The rod fails safe to the retracted position on air loss.
It uses a fixed TPU bumper at each end to decelerate the stroke over the last few millimeters. This bumper is not adjustable. At high speeds with heavy tooling mass, meter-out the exhaust or add an external shock absorber.
