Airtac PSB Single Acting Compact Cylinder PSB10X50U
The AirTAC Airtac PSB Single Acting Compact Cylinder PSB10X50U 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 PSB10X50U
The AirTAC PSB10X50U is a JIS pen-size single-acting push cylinder with a 50 mm stroke. Air entering the single M5x0.8 port extends the Ø4 mm rod, while an internal spring retracts it upon exhaust. 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, with the return spring force already deducted.
The U suffix denotes a 90-degree side inlet for flat plumbing in confined spaces. A fixed TPU bumper cushions the stroke ends. Because the return spring sets a minimum operating pressure of 0.2 MPa, the rod requires this threshold to move. The slim SUS304 stainless body suits damp or tight jigs, and the M8x1.0 rod-end thread handles standard mounting.
Airtac PSB Single Acting Compact Cylinder PSB10X50U Technical Specifications
| Model | Airtac PSB Single Acting Compact Cylinder PSB10X50U |
|---|---|
| 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 PSB10X50U Is Used
Part Ejection
Pushes machined pins off a conveyor belt; the spring safely pulls the rod back when air is cut.
Flap Folding
Extends to fold cardboard flaps on a packaging line, relying on the 90-degree side inlet for tight clearances.
Clamp Release
Actuates a brief hold-down clamp on an assembly fixture, returning to a safe retracted state on air loss.
Is the Airtac PSB Single Acting Compact Cylinder PSB10X50U the Right Cylinder?
This 10 mm bore provides 29.8 N net push at 0.5 MPa and 45.5 N at 0.7 MPa maximum. If your task needs less force, the 6 mm bore offers 10.6 N at 0.5 MPa; for heavier loads, the 12 mm bore yields 42.9 N at 0.5 MPa. Plan for a safe working load of roughly 18 N, which is about 60 percent of the 0.5 MPa rating, to account for seal friction.
With a 50 mm stroke, the slender Ø4 mm rod needs an external guide or linear bearing to prevent side-loading damage. Confirm your ordering essentials: 10 mm bore, 50 mm stroke, no magnet, U side inlet, and your preferred mounting bracket.
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 PSB10X50U FAQ
It delivers 29.8 N net push at 0.5 MPa and 45.5 N at 0.7 MPa maximum. The internal spring requires a minimum 0.2 MPa to extend the rod, and it fails safe to the retracted position on air loss.
It uses a fixed TPU bumper at each end to decelerate the last few millimeters of travel. Because it is not adjustable, metering out the exhaust or adding an external shock absorber is recommended at higher speeds with heavy tooling mass.
