Airtac PSB Single Acting Compact Cylinder PSB16X25R
The AirTAC Airtac PSB Single Acting Compact Cylinder PSB16X25R is a single acting, push type (spring return) pen-size mini cylinder with a Ø16mm bore and 25mm 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 PSB16X25R
The AirTAC PSB16X25R is a 16 mm bore, single-acting push cylinder with a 25 mm stroke and an R axial inlet. Air entering the M5x0.8 port extends the rod, while an internal spring retracts it upon exhaust. This fail-safe design ensures the rod returns home if air pressure drops. It supplies 74.8 N of net push at 0.5 MPa and 115 N at 0.7 MPa.
The slim SUS304 stainless body fits tight jigs, and the M10x1.0 rod end handles secure tooling attachment. Because the return spring consumes energy, plan for a safe working load of about 45 N, which is roughly 60 percent of the 0.5 MPa rating. A fixed TPU bumper cushions the stroke ends, though heavy tooling mass may require external shock absorption.
Airtac PSB Single Acting Compact Cylinder PSB16X25R Technical Specifications
| Model | Airtac PSB Single Acting Compact Cylinder PSB16X25R |
|---|---|
| Series | PSB JIS pen-size mini cylinder |
| Bore size | Ø16 mm |
| Rod diameter | Ø5 mm |
| Stroke | 25 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 PSB16X25R Is Used
Part Ejection
Pushes finished plastic parts out of a molding fixture; the spring safely pulls the ejector pin back when air is cut.
Clamp Release
Holds a workpiece during machining, then retracts the stopper pin automatically on air loss to free the part.
Gate Diverter
Extends a deflector plate to route small packages on a packaging line, returning to home position via spring force.
Is the Airtac PSB Single Acting Compact Cylinder PSB16X25R the Right Cylinder?
This 16 mm bore provides the highest net push in the PSB series, stepping up from the 12 mm bore which yields 42.9 N at 0.5 MPa. It requires a minimum operating pressure of 0.2 MPa to overcome the spring before movement begins. The R suffix specifies the axial air inlet for in-line plumbing.
Confirm your ordering essentials: 16 mm bore, 25 mm stroke, no magnet, R back cover, and your preferred mounting bracket. The internal spring holds the rod retracted without live air, making it ideal for clamp-release and ejection tasks.
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 PSB16X25R FAQ
The net push force is 74.8 N at 0.5 MPa and 115 N at the 0.7 MPa maximum. It requires a minimum of 0.2 MPa to overcome the internal return spring and move the rod.
It uses a fixed TPU bumper at each end to decelerate the stroke over the last few millimeters. It is not an adjustable shock absorber, so at high speeds with heavy tooling you should meter-out the exhaust or add external damping.
