Airtac PSB Single Acting Compact Cylinder PSB16X30CB
The AirTAC Airtac PSB Single Acting Compact Cylinder PSB16X30CB 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 PSB16X30CB
The AirTAC PSB16X30CB is a JIS pen-size single-acting push cylinder with a 16mm bore and 30mm stroke. Air entering the single M5x0.8 port extends the Ø5mm rod, while an internal spring retracts it upon exhaust. This fail-safe design ensures the rod returns home if air pressure drops, making it ideal for part ejection or gate operations. It supplies 74.8N of net push at 0.5 MPa.
Featuring a CB double clevis back cover, this unit accommodates pivoting loads. The SUS304 stainless barrel and slim body fit easily into tight jigs. A fixed TPU bumper decelerates the stroke at each end. For practical sizing, plan for a safe working load of roughly 45N, which accounts for seal friction at standard pressure.
Airtac PSB Single Acting Compact Cylinder PSB16X30CB Technical Specifications
| Model | Airtac PSB Single Acting Compact Cylinder PSB16X30CB |
|---|---|
| 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 PSB16X30CB Is Used
Pivoting Part Diverter
Uses the CB double clevis to swing parts across a belt; the spring-return design safely pulls the diverter back when air is cut.
Carton Flap Folder
Extends to fold heavy cardboard flaps on a packaging line, relying on the 74.8N net push at 0.5 MPa to overcome board stiffness.
Fail-Safe Ejector Gate
Pushes completed parts off an assembly station, with the internal spring guaranteeing the gate retracts clear on air loss.
Is the Airtac PSB Single Acting Compact Cylinder PSB16X30CB the Right Cylinder?
This 16mm bore provides 74.8N net push at 0.5 MPa and 115N at the 0.7 MPa maximum. If your application requires less force, stepping down to the 12mm bore yields 42.9N at 0.5 MPa. Because 16mm is the largest standard pen-size option, moving beyond it requires a different body style for higher output. The internal return spring sets a 0.2 MPa minimum operating pressure before motion begins.
Confirm your ordering essentials: 16mm bore, 30mm stroke, CB double clevis inlet, and no magnet. The thin Ø5mm rod handles coaxial thrust well, but over this 30mm stroke you should add an external guide for any off-axis loads.
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 PSB16X30CB FAQ
The net push force is 74.8N at 0.5 MPa and 115N at the 0.7 MPa maximum. Because an internal spring opposes the air stroke, a minimum operating pressure of 0.2 MPa is required before the rod 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 last few millimeters of travel; at high speeds with heavy tooling mass, meter-out the exhaust or add an external shock absorber. The CB back cover provides a double clevis for pivoting loads, and no sensor magnet is installed.
