Airtac PSB Single Acting Compact Cylinder PSB16X30SCB
The AirTAC Airtac PSB Single Acting Compact Cylinder PSB16X30SCB 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 PSB16X30SCB
The AirTAC PSB16X30SCB is a JIS pen-size single-acting push cylinder featuring a 16 mm bore, 30 mm stroke, built-in magnet, and CB double clevis pivot mount. Air entering the single M5x0.8 port extends the Ø5 mm rod, while an internal spring ensures fail-safe retraction upon air loss. Because the spring constantly opposes the air stroke, the usable output is 74.8 N net push at 0.5 MPa and 115 N at 0.7 MPa.
This slim stainless steel body simplifies valving and tubing by requiring just one solenoid line. A fixed TPU bumper at each end decelerates the stroke over the final few millimeters. For higher speeds with heavy tooling mass, meter-out the exhaust or add an external shock absorber, as the bumper is not adjustable. The integrated -S magnet supports AirTAC reed or electronic switches for precise position sensing.
Airtac PSB Single Acting Compact Cylinder PSB16X30SCB Technical Specifications
| Model | Airtac PSB Single Acting Compact Cylinder PSB16X30SCB |
|---|---|
| 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 PSB16X30SCB Is Used
CNC Part Ejector
Pushes finished aluminum parts out of a machining fixture; the spring-return design guarantees the ejector rod safely retracts if shop air pressure suddenly drops.
Package Diverter Gate
Actuates a pivoting sorting gate on a packaging line; the CB double clevis accommodates the pivot arc while the single air line keeps control wiring simple.
Clamp Release Mechanism
Holds a workpiece against a stop during light assembly; air extends the rod to push the clamp open, and the spring securely closes it during an air loss event.
Is the Airtac PSB Single Acting Compact Cylinder PSB16X30SCB the Right Cylinder?
Selecting this 16 mm bore provides maximum push force for the PSB family. If your application requires less force, stepping down to the 12 mm bore yields 42.9 N net push at 0.5 MPa. Since 16 mm is the largest available pen-size option, moving beyond 115 N at 0.7 MPa requires switching to a larger non-pen cylinder family. Keep in mind the internal return spring sets a minimum operating pressure of 0.2 MPa before the rod will move. Confirm your ordering essentials: 16 mm bore, 30 mm stroke, -S magnet, CB double clevis back cover, and any required mounting brackets.
For practical sizing, plan for a safe working load of about 45 N, which assumes roughly 60 percent of the 74.8 N theoretical force to account for seal friction and smooth travel. Alternatively, this equates to lifting about 3.8 kg vertically with a sane 2:1 safety margin. The Ø5 mm rod is designed for coaxial thrust; over long strokes or off-axis loads, add an external guide or linear bearing to prevent side-load damage.
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 PSB16X30SCB FAQ
The net push force is 74.8 N at 0.5 MPa and 115 N at 0.7 MPa. Because an internal spring returns the rod, a minimum operating pressure of 0.2 MPa is required before the piston moves, and 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; it is not adjustable, so meter-out the exhaust or use an external shock absorber for heavy loads. The -S option includes a built-in piston magnet compatible with AirTAC reed or electronic switches.
