Airtac PSB Single Acting Compact Cylinder PSB10X50SU
The AirTAC Airtac PSB Single Acting Compact Cylinder PSB10X50SU is a single acting, push type (spring return) pen-size mini cylinder with a Ø10mm bore and 50mm 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 PSB10X50SU
The AirTAC PSB10X50SU is a JIS pen-size single-acting push cylinder, meaning air entering one M5x0.8 port extends the rod while an internal spring retracts it. This fail-safe design ensures the rod returns home if air pressure drops. It supplies 29.8 N of net push at 0.5 MPa and 45.5 N at 0.7 MPa.
The slim SUS304 stainless body fits tight jigs, and the U suffix denotes a 90-degree side inlet for flat plumbing. A fixed TPU bumper cushions the stroke ends. Because the return spring sets a 0.2 MPa minimum operating pressure, the rod will not move below that threshold.
Airtac PSB Single Acting Compact Cylinder PSB10X50SU Technical Specifications
| Model | Airtac PSB Single Acting Compact Cylinder PSB10X50SU |
|---|---|
| Series | PSB JIS pen-size mini cylinder |
| Bore size | Ø10 mm |
| Rod diameter | Ø4 mm |
| Stroke | 50 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 (Ø10mm)
| Pressure | Net push force |
|---|---|
| 0.5 MPa | 29.8 N |
| 0.7 MPa (max) | 45.5 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 PSB10X50SU Is Used
Part Ejector
Pushes finished plastic parts off a conveyor belt; the spring safely retracts the pin if the airline loses pressure.
Carton Flap Folder
Extends to fold small cardboard flaps during case packing, relying on the compact 90-degree side inlet to fit narrow frames.
Clamp Release
Acts as a fail-safe clamp release on a light assembly fixture, holding parts retracted during an emergency air cutoff.
Is the Airtac PSB Single Acting Compact Cylinder PSB10X50SU the Right Cylinder?
This 10 mm bore provides 29.8 N net push at 0.5 MPa. Stepping down to a 6 mm bore yields 10.6 N, while moving up to a 12 mm bore offers 42.9 N. Plan for a safe working load of roughly 18 N, which is about 60 percent of the rated 0.5 MPa figure to account for friction.
With a 50 mm stroke, the slender Ø4 mm rod requires an external guide or linear bearing to prevent side-loading damage. The S suffix adds a piston magnet for position sensing with reed or electronic switches. Confirm your ordering code covers the bore, stroke, magnet, U side inlet, 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 PSB10X50SU FAQ
The net push force is 29.8 N at 0.5 MPa and 45.5 N at 0.7 MPa. Because the internal return spring opposes the air stroke, a minimum operating pressure of 0.2 MPa is required before the rod moves.
The fixed TPU bumper decelerates the rod over the last few millimeters of travel. At higher speeds with real tooling mass, meter-out the exhaust or add an external shock absorber. The S suffix provides a built-in magnet for reed or electronic switches.
