Airtac PSB Single Acting Compact Cylinder PSB16X25SCB
The AirTAC Airtac PSB Single Acting Compact Cylinder PSB16X25SCB 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 PSB16X25SCB
The AirTAC PSB16X25SCB is a single-acting push pen cylinder that extends via one M5x0.8 air port and retracts via an internal spring. It provides 74.8 N of net push at 0.5 MPa, with the spring force already deducted. This fail-safe design ensures the rod returns home if air pressure drops.
Built with a SUS304 stainless barrel and a slim Ø5 mm rod, it suits tight jigs. The CB double clevis allows pivoting loads, and the -S suffix denotes a built-in magnet for electronic or reed switches. A fixed TPU bumper cushions the stroke ends.
Airtac PSB Single Acting Compact Cylinder PSB16X25SCB Technical Specifications
| Model | Airtac PSB Single Acting Compact Cylinder PSB16X25SCB |
|---|---|
| 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 PSB16X25SCB Is Used
CNC Part Ejector
Pushes finished aluminum parts out of a machining center. The spring-return design safely pulls the rod back if air fails, preventing collisions.
Package Diverter Gate
Actuates a sorting flap on a packaging line. The CB double clevis accommodates the pivot arc while the bumper absorbs the stroke impact.
Clamp Release Mechanism
Holds a workpiece during assembly and releases it when air is removed. The fail-safe retract ensures the clamp opens automatically during an emergency stop.
Is the Airtac PSB Single Acting Compact Cylinder PSB16X25SCB the Right Cylinder?
This 16 mm bore generates 74.8 N net push at 0.5 MPa. If you need less force, the 12 mm bore offers 42.9 N; if you need more, consider a double-acting PB cylinder. The internal spring sets a 0.2 MPa minimum pressure before motion begins. Plan for a safe working load of about 45 N, which is roughly 60 percent of the 0.5 MPa rating.
Confirm your ordering essentials: 16 mm bore, 25 mm stroke, -S magnet, CB double clevis, and any mounting brackets. The thin rod handles coaxial thrust, so add an external guide for 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 PSB16X25SCB FAQ
It delivers 74.8 N net push at 0.5 MPa and 115 N at 0.7 MPa maximum. The internal return spring requires a minimum of 0.2 MPa before the rod can extend.
It uses a fixed TPU bumper at each end to decelerate the last few millimeters of travel; for high speeds with heavy tooling, add an external shock absorber. The -S suffix means it has a built-in piston magnet compatible with AirTAC reed or electronic switches.
