Airtac PSB Single Acting Compact Cylinder PSB16X5R
The AirTAC Airtac PSB Single Acting Compact Cylinder PSB16X5R 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 PSB16X5R
The AirTAC PSB16X5R is a single-acting push cylinder that uses one air line to extend the rod, while a built-in spring retracts it on exhaust. This fail-safe design ensures the rod returns home if air pressure drops, making it ideal for clamp-release and part-eject tasks. It delivers 74.8 N of net push at 0.5 MPa and 115 N at 0.7 MPa.
Built on a slim JIS pen-size body with SUS304 stainless steel rod and barrel, it fits tight jigs and damp environments. The bore uses an M5x0.8 port and an M10x1.0 rod-end thread. A fixed TPU bumper cushions the stroke ends. Plan for a safe working load of about 45 N, which is roughly 60 percent of the 0.5 MPa rating.
Airtac PSB Single Acting Compact Cylinder PSB16X5R Technical Specifications
| Model | Airtac PSB Single Acting Compact Cylinder PSB16X5R |
|---|---|
| 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 PSB16X5R Is Used
Part Ejection
Pushes finished metal parts out of a CNC machining center. The spring-return design guarantees the ejector clears the work area when air is cut.
Gate Diverter
Acts as a sorting gate on a packaging conveyor. The axial R inlet keeps plumbing compact along the line while the fail-safe retract opens the gate on emergency stops.
Clamp Release
Secures wood panels during a routing cut. Air extends the rod to hold the part, and the spring pulls back instantly to release the panel for fast cycling.
Is the Airtac PSB Single Acting Compact Cylinder PSB16X5R the Right Cylinder?
This 16 mm bore provides the maximum push in the series with 74.8 N at 0.5 MPa, stepping up from the 12 mm bore's 42.9 N. It is the top size for pen-size force needs. The internal spring requires a minimum of 0.2 MPa before the rod moves. The R suffix specifies an axial air inlet for in-line plumbing.
When ordering, confirm the 5 mm stroke, the lack of a sensor magnet, and your mounting bracket needs. The thin Ø5 mm rod handles coaxial thrust well, but you should add an external guide for any off-axis loads. With a 2:1 safety margin, this model lifts about 3.8 kg vertically.
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 PSB16X5R FAQ
The net push force is 74.8 N at 0.5 MPa and 115 N at the 0.7 MPa maximum. The return spring creates resistance, so a minimum of 0.2 MPa is required before the rod extends. If air loss occurs, the spring fail-safe retracts the rod automatically.
It uses a fixed TPU bumper at the stroke ends to decelerate motion over the last few millimeters. Because it is not adjustable, you should meter-out the exhaust or add an external shock absorber when cycling at high speeds with heavy tooling mass to prevent bottoming out.
