Airtac PSB Single Acting Compact Cylinder PSB16X5CB
The AirTAC Airtac PSB Single Acting Compact Cylinder PSB16X5CB is a single acting, push type (spring return) pen-size mini cylinder with a Ø16mm bore and 5mm 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 PSB16X5CB
The AirTAC PSB16X5CB is a JIS pen-size single-acting push cylinder with a 5 mm stroke. Air entering the M5x0.8 port extends the Ø5 mm rod, while an internal spring retracts it upon exhaust. This fail-safe design ensures the rod returns home if air pressure drops. It delivers 74.8 N of net push at 0.5 MPa and 115 N at 0.7 MPa.
The CB double clevis back cover accommodates pivoting loads, and the SUS304 stainless barrel suits damp or tight jigs. A fixed TPU bumper decelerates the stroke's final millimeters. For smooth operation, plan on a safe working load of about 45 N, which accounts for friction. If lifting vertically, expect to handle roughly 3.8 kg with a 2:1 safety margin.
Airtac PSB Single Acting Compact Cylinder PSB16X5CB Technical Specifications
| Model | Airtac PSB Single Acting Compact Cylinder PSB16X5CB |
|---|---|
| Series | PSB JIS pen-size mini cylinder |
| Bore size | Ø16 mm |
| Rod diameter | Ø5 mm |
| Stroke | 5 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 PSB16X5CB Is Used
Pivoting Part Ejector
Uses the CB double clevis to swing and push completed plastic moldings off a conveyor belt, relying on the spring to safely retract the rod during an air loss event.
Light Duty Clamp
Holds a thin aluminum workpiece against a machining jig with 74.8 N of net push at 0.5 MPa, releasing instantly when the single solenoid line exhausts.
Carton Flap Folder
Extends 5 mm to fold a small cardboard flap on a packaging line, with the fail-safe retract ensuring the mechanism clears the path when the system stops.
Is the Airtac PSB Single Acting Compact Cylinder PSB16X5CB the Right Cylinder?
This 16 mm bore provides the highest net push in the PSB family, offering 74.8 N at 0.5 MPa. If your application needs less force, stepping down to the Ø12 model yields 42.9 N at the same pressure. The internal return spring requires a minimum of 0.2 MPa to move the rod. Confirm your ordering essentials: 16 mm bore, 5 mm stroke, CB double clevis inlet, and no magnet.
Because the rod is only Ø5 mm, use an external guide or linear bearing for off-axis loads over long strokes. The thin rod is built for coaxial thrust, not side load. At higher cycling speeds with real tooling mass, the fixed TPU bumper may bottom out, so meter-out the exhaust or add an external shock absorber.
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 PSB16X5CB FAQ
The net push force is 74.8 N at 0.5 MPa and 115 N at 0.7 MPa (the maximum operating pressure). Because an internal spring returns the rod, a minimum pressure of 0.2 MPa is required before the rod moves. The spring holds the rod retracted on air loss.
It uses a fixed TPU bumper to decelerate the last few millimeters of travel, which is not adjustable. The CB back cover provides a double clevis for pivoting loads. At high speeds with heavy tooling, meter-out the exhaust or add an external shock absorber, as the bumper can bottom out.
