Airtac PSB Single Acting Compact Cylinder PSB16X40R
The AirTAC Airtac PSB Single Acting Compact Cylinder PSB16X40R is a single acting, push type (spring return) pen-size mini cylinder with a Ø16mm bore and 40mm 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 PSB16X40R
The AirTAC PSB16X40R is a JIS pen-size single-acting push cylinder with a 40 mm stroke. Air entering the M5x0.8 axial port extends the rod, while an internal spring retracts it on exhaust. This fail-safe design ensures the rod returns home if air pressure drops, needing only one solenoid line for simpler tubing. It provides 74.8 N of net push at 0.5 MPa and 115 N at 0.7 MPa.
Built with a SUS304 stainless barrel and a slim mini body, it fits tight jigs and light end-of-arm tooling. The Ø5 mm piston rod has an M10x1.0 end thread. A fixed TPU bumper at each end decelerates motion over the last few millimeters. 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 PSB16X40R Technical Specifications
| Model | Airtac PSB Single Acting Compact Cylinder PSB16X40R |
|---|---|
| Series | PSB JIS pen-size mini cylinder |
| Bore size | Ø16 mm |
| Rod diameter | Ø5 mm |
| Stroke | 40 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 PSB16X40R Is Used
Part Ejection
Pushes machined aluminum brackets off a conveyor belt. The spring-return design keeps the retracted position safe during an air loss event.
Flap Folding
Extends to fold cardboard flaps on a packaging line. One solenoid line simplifies wiring, while the fixed TPU bumper softens the extend stop.
Clamp Release
Applies 45 N of safe holding force to secure a plastic housing during ultrasonic welding, then springs back to release the part.
Is the Airtac PSB Single Acting Compact Cylinder PSB16X40R the Right Cylinder?
This 16 mm bore provides 74.8 N net push at 0.5 MPa. Stepping down to the 12 mm bore yields 42.9 N, while this 16 mm model offers the highest force in the pen-size range. The internal spring sets a 0.2 MPa minimum operating pressure before motion begins. Because the spring constantly opposes air, the rod stays retracted during air loss.
The thin Ø5 mm rod handles coaxial thrust but needs an external guide for off-axis loads over this 40 mm stroke. The R suffix specifies an axial air inlet. Confirm your ordering essentials: bore, stroke, lack of a sensor magnet, and mounting brackets.
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 PSB16X40R FAQ
The net push force is 74.8 N at 0.5 MPa and 115 N at the 0.7 MPa maximum. The internal return spring requires a minimum of 0.2 MPa before the rod can extend. If air is lost, the spring pulls the rod back to the retracted position.
Air drives the rod out, and the spring retracts it, requiring only one air line. A fixed TPU bumper at each end cushions the last few millimeters of travel. At high speeds with heavy tooling mass, meter-out the exhaust or add an external shock absorber, as the bumper is not adjustable.
