Airtac PSB Single Acting Compact Cylinder PSB16X30SR
The AirTAC Airtac PSB Single Acting Compact Cylinder PSB16X30SR 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 PSB16X30SR
The AirTAC PSB16X30SR is a JIS pen-size single-acting push cylinder that extends via one M5x0.8 air port and retracts via a built-in spring. This fail-safe design ensures the rod pulls home automatically upon air loss, requiring only one solenoid line for simpler tubing. It delivers 74.8 N of net push at 0.5 MPa and 115 N at 0.7 MPa.
Built with a SUS304 stainless rod and barrel, the slim 16 mm body fits tight jigs while the M10x1.0 rod-end thread handles secure tooling attachment. The integrated -S magnet supports reed or electronic switches for position sensing, and a fixed TPU bumper cushions the stroke ends.
Airtac PSB Single Acting Compact Cylinder PSB16X30SR Technical Specifications
| Model | Airtac PSB Single Acting Compact Cylinder PSB16X30SR |
|---|---|
| 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 PSB16X30SR Is Used
Part Ejection
Uses the spring-return retract to safely pull the ejector pin back during air loss, preventing jams on an automated milling line.
Gate Diverter
Pushes a lightweight routing flap to sort packages, relying on the fail-safe retract to clear the lane when the system stops.
Clamp Release
Applies 45 N of safe holding force to secure a carton during sealing, then exhausts to let the spring release the grip instantly.
Is the Airtac PSB Single Acting Compact Cylinder PSB16X30SR the Right Cylinder?
This 16 mm bore provides the highest net push in the series at 74.8 N (0.5 MPa) and 115 N (0.7 MPa). If you need less force, the 12 mm bore yields 42.9 N at 0.5 MPa. Plan for a safe working load of about 45 N (roughly 60% of the 0.5 MPa figure) to account for friction. The spring sets a 0.2 MPa minimum pressure before motion begins. Confirm your ordering essentials: 16 mm bore, 30 mm stroke, -S magnet, R axial inlet, and 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 PSB16X30SR 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 begins to move, and the cylinder fails safe in the retracted position upon air loss.
The -S suffix indicates a built-in piston magnet compatible with reed or electronic switches. Cushioning relies on a fixed TPU bumper at each end; because it only decelerates the last few millimeters, you should meter-out the exhaust or add an external shock absorber when cycling heavy tooling at high speeds.
