Airtac PSB Single Acting Compact Cylinder PSB4X10
The AirTAC Airtac PSB Single Acting Compact Cylinder PSB4X10 is a single acting, push type (spring return) pen-size mini cylinder with a Ø4mm bore and 10mm 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 PSB4X10
The AirTAC PSB4X10 is a single-acting push pen cylinder that extends via air pressure and retracts via an internal spring. It provides 4.1 N of net push at 0.5 MPa and 6.6 N at 0.7 MPa. Because the spring force is already subtracted, these are your true usable thrust figures. This design requires only one solenoid line, simplifying tubing and lowering valve costs.
Built with a slim bronze barrel and a stainless rod, it fits tight spaces and light end-of-arm tooling. The bore uses an M3x0.5 port for small tube fittings and an M4x0.7 rod-end thread. If air pressure drops, the spring ensures the rod fails safely back to its retracted home position. Note that this 4 mm bore variant has no end cushion or bumper.
Airtac PSB Single Acting Compact Cylinder PSB4X10 Technical Specifications
| Model | Airtac PSB Single Acting Compact Cylinder PSB4X10 |
|---|---|
| Series | PSB JIS pen-size mini cylinder |
| Bore size | Ø4 mm |
| Rod diameter | Ø2 mm |
| Stroke | 10 mm |
| Acting type | Single acting, push type (spring return) |
| Port size | M3×0.5 (tube) |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.3 – 0.7 MPa |
| Proof pressure | 1.2 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 50 – 500 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 (Ø4mm)
| Pressure | Net push force |
|---|---|
| 0.5 MPa | 4.1 N |
| 0.7 MPa (max) | 6.6 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 PSB4X10 Is Used
Micro Part Ejection
Pushes tiny molded components out of a machining fixture, relying on the spring to safely retract the pin when air is cut.
Lab Sample Sorter
Acts as a diverter for light vials on a diagnostic carousel, using a single air line to keep the control panel simple.
Small Part Clamp
Holds a delicate electronic substrate in place for a quick gluing operation, releasing automatically on air loss.
Is the Airtac PSB Single Acting Compact Cylinder PSB4X10 the Right Cylinder?
This 4 mm bore model offers 4.1 N net push at 0.5 MPa. If your task needs less force, you are at the smallest available size in this series. If you need more power, stepping up to the 6 mm bore yields 10.6 N at 0.5 MPa. The internal spring sets a minimum operating pressure of 0.3 MPa before the rod will move. Plan for a safe working load of about 2 N, which is roughly 60 percent of the rated thrust, to account for seal friction. When ordering, confirm the 10 mm stroke, the lack of a magnetic sensor, and your mounting bracket choice.
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 0.3 – 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 PSB4X10 FAQ
The net push force is 4.1 N at 0.5 MPa and 6.6 N at 0.7 MPa. The internal return spring requires a minimum operating pressure of 0.3 MPa to extend the rod. If air is lost, the spring pulls the rod back to a fail-safe retracted state.
This specific 4 mm bore model does not include a magnetic sensor option. It also lacks an end cushion or bumper, meaning the stroke ends with a hard metal stop. The thin 2 mm rod is designed for coaxial thrust, so avoid side loads and add an external guide if needed.
