Airtac PSB Single Acting Compact Cylinder PSB16X30R
The AirTAC Airtac PSB Single Acting Compact Cylinder PSB16X30R 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 PSB16X30R
The AirTAC PSB16X30R is a JIS pen-size single-acting push cylinder that extends via one M5x0.8 air line and retracts via an internal spring. It supplies 74.8 N of net push at 0.5 MPa, reaching 115 N at the 0.7 MPa maximum. The SUS304 stainless barrel and slim body fit easily into tight jigs.
Because the spring naturally exhausts the rod to a fail-safe retracted position, your process stays secure during air loss. The R axial inlet keeps plumbing in-line, while the fixed TPU bumper decelerates the stroke near the end of travel.
Airtac PSB Single Acting Compact Cylinder PSB16X30R Technical Specifications
| Model | Airtac PSB Single Acting Compact Cylinder PSB16X30R |
|---|---|
| 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 PSB16X30R Is Used
Part Ejection
Uses the spring-return push to eject machined components from a CNC fixture, ensuring the rod safely pulls back if compressed air drops.
Gate Diverter
Sorts packages on a packaging line by extending to block or guide flow, with the fail-safe retract clearing the path during outages.
Clamp Release
Holds a workpiece in place during a light drilling operation, relying on the spring to release the part automatically upon exhaust.
Is the Airtac PSB Single Acting Compact Cylinder PSB16X30R the Right Cylinder?
This 16 mm bore generates 74.8 N net push at 0.5 MPa. Stepping down, the 12 mm bore yields 42.9 N; stepping up is not available as this is the largest standard diameter. Plan for a safe working load of roughly 45 N, which accounts for seal friction at 60 percent of the rated force. For vertical movements, expect to lift about 3.8 kg with a sane 2:1 margin.
The internal return spring requires at least 0.2 MPa before motion begins. The Ø5 mm piston rod handles coaxial thrust well, but add an external linear bearing if your application involves off-axis loads. Confirm your ordering essentials: 16 mm bore, 30 mm stroke, R axial inlet, and no magnet.
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 PSB16X30R FAQ
It provides 74.8 N of net push at 0.5 MPa and 115 N at 0.7 MPa. The internal spring requires a minimum of 0.2 MPa to overcome return force and extend the rod. If air is lost, the spring ensures the cylinder fails safely in the retracted position.
It uses a fixed TPU bumper at each end to decelerate the piston over the last few millimeters of travel. Because it is not adjustable, you should meter-out the exhaust or add an external shock absorber when moving heavy tooling at high speeds to prevent bottoming out.
