Airtac PSB Single Acting Compact Cylinder PSB6X30R
The AirTAC Airtac PSB Single Acting Compact Cylinder PSB6X30R is a single acting, push type (spring return) pen-size mini cylinder with a Ø6mm bore and 30mm 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 PSB6X30R
The AirTAC PSB6X30R is a single-acting push pen cylinder that extends its Ø3 mm rod using one M5x0.8 air line, while a built-in spring handles the retract stroke. It delivers 10.6 N of net push at 0.5 MPa and 16.3 N at 0.7 MPa. This fail-safe design ensures the rod pulls back automatically if air pressure drops, keeping your workspace clear.
Built with a SUS304 stainless barrel and a slim mini body, it fits easily into tight jigs and light end-of-arm tooling. A fixed TPU bumper cushions the stroke ends. For practical sizing, plan for a safe working load of about 6 N, which accounts for seal friction and smooth travel.
Airtac PSB Single Acting Compact Cylinder PSB6X30R Technical Specifications
| Model | Airtac PSB Single Acting Compact Cylinder PSB6X30R |
|---|---|
| Series | PSB JIS pen-size mini cylinder |
| Bore size | Ø6 mm |
| Rod diameter | Ø3 mm |
| Stroke | 30 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 (Ø6mm)
| Pressure | Net push force |
|---|---|
| 0.5 MPa | 10.6 N |
| 0.7 MPa (max) | 16.3 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 PSB6X30R Is Used
Small Part Ejection
Pushes lightweight molded plastic parts out of a machining fixture. The spring-return design guarantees the ejector clears the workspace when air is removed.
Package Diverter Gate
Acts as a lightweight routing flap on a packaging line. Its slim pen-size body mounts flush between conveyor rollers without blocking product flow.
Lab Test Actuator
Provides a precise push force for engaging micro-switches or sensors on a test bench. The single air line simplifies valving and tubing setup.
Is the Airtac PSB Single Acting Compact Cylinder PSB6X30R the Right Cylinder?
When sizing this 6 mm bore unit against its neighbors, note it provides 10.6 N net push at 0.5 MPa. Stepping down to the Ø4 yields just 4.1 N, while moving up to the Ø10 offers 29.8 N. The internal return spring requires a minimum operating pressure of 0.2 MPa before the rod will move. Confirm your ordering essentials: 6 mm bore, 30 mm stroke, no magnet, R axial inlet, and your preferred mounting bracket.
Because the rod is only Ø3 mm, it is built for coaxial thrust rather than side loading. Over this 30 mm stroke, add an external guide or linear bearing if your application involves off-axis forces to prevent rod bending.
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 PSB6X30R FAQ
The net push force is 10.6 N at 0.5 MPa and 16.3 N at 0.7 MPa (maximum pressure). Because the internal spring opposes the air stroke, a minimum operating pressure of 0.2 MPa is required before the rod extends. The spring automatically retracts the rod on air loss.
It uses a fixed TPU bumper at each end to decelerate the stroke over the last few millimeters. This bumper is not adjustable and will bottom out under high speeds with heavy tooling mass. In those cases, meter-out the exhaust or add an external shock absorber.
