Airtac PSB Single Acting Compact Cylinder PSB16X50U
The AirTAC Airtac PSB Single Acting Compact Cylinder PSB16X50U is a single acting, push type (spring return) pen-size mini cylinder with a Ø16mm bore and 50mm 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 PSB16X50U
The AirTAC PSB16X50U is a 16 mm bore, 50 mm stroke single-acting push cylinder with a built-in spring return. Air fed to the single M5x0.8 port extends the rod, while exhausting the line allows the spring to fail-safe retract it. This design cuts tubing and valving complexity since only one solenoid line is required. The slim SUS304 stainless body and barrel resist moisture in tight spaces.
Delivering 74.8 N of net push at 0.5 MPa and 115 N at the 0.7 MPa maximum, the return spring force is already deducted from these figures. The U suffix denotes a 90-degree side inlet for flat plumbing. A fixed TPU bumper cushions the stroke ends, and the M10x1.0 rod-end thread handles tooling mounting.
Airtac PSB Single Acting Compact Cylinder PSB16X50U Technical Specifications
| Model | Airtac PSB Single Acting Compact Cylinder PSB16X50U |
|---|---|
| Series | PSB JIS pen-size mini cylinder |
| Bore size | Ø16 mm |
| Rod diameter | Ø5 mm |
| Stroke | 50 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 PSB16X50U Is Used
Stamping Ejector
Pushes formed metal parts out of a die on a press line, relying on the spring to retract the pin safely during air loss.
Package Diverter
Extends a flat blade to route small cartons on a packaging conveyor, with the 90-degree side inlet keeping the footprint narrow.
Clamp Release
Applies 74.8 N of hold-down force at 0.5 MPa on an assembly fixture, automatically releasing the workpiece when air is removed.
Is the Airtac PSB Single Acting Compact Cylinder PSB16X50U the Right Cylinder?
This 16 mm bore yields 74.8 N net push at 0.5 MPa. Sizing down, the 12 mm bore gives 42.9 N at the same pressure. Because 16 mm is the largest in this series, there is no larger option; if you need more force without a spring deduction, consider the double-acting PB series. The internal spring sets a 0.2 MPa minimum pressure before motion begins, and the rod retracts safely upon air loss. Confirm your ordering code details: bore, stroke, no magnet, U side inlet, and any mounting brackets.
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 PSB16X50U 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 of 0.2 MPa before the rod extends, and the rod fails safe to the retracted position on air loss.
It uses a fixed TPU bumper at each end that only decelerates the last few millimeters. At higher speeds with real tooling mass, meter-out the exhaust or add an external shock absorber. The thin 5 mm rod is built for coaxial thrust, so add an external linear bearing for any off-axis loads.
