Airtac PSB Single Acting Compact Cylinder PSB6X20R
The AirTAC Airtac PSB Single Acting Compact Cylinder PSB6X20R is a single acting, push type (spring return) pen-size mini cylinder with a Ø6mm bore and 20mm 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 PSB6X20R
The AirTAC PSB6X20R is a JIS pen-size single-acting push cylinder that extends its Ø3 mm rod via one M5x0.8 air port. A built-in spring retracts the piston on exhaust, ensuring the rod safely returns home if air pressure drops. It delivers 10.6 N of net push at 0.5 MPa and 16.3 N at 0.7 MPa.
Featuring a SUS304 stainless barrel and slim body, it fits tight spaces and damp jigs. The R axial inlet keeps plumbing in-line. A fixed TPU bumper decelerates the stroke ends. Plan for a safe working load of roughly 6 N to account for seal friction and smooth travel.
Airtac PSB Single Acting Compact Cylinder PSB6X20R Technical Specifications
| Model | Airtac PSB Single Acting Compact Cylinder PSB6X20R |
|---|---|
| Series | PSB JIS pen-size mini cylinder |
| Bore size | Ø6 mm |
| Rod diameter | Ø3 mm |
| Stroke | 20 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 PSB6X20R Is Used
Small Part Ejector
Pushes lightweight stamped electronics components out of a die with a compact 6 mm stroke.
Sorting Diverter
Acts as a spring-return gate to deflect small plastic bottles on a packaging line.
Clamp Release
Holds a delicate workpiece forward under air, then safely retracts when the valve exhausts.
Is the Airtac PSB Single Acting Compact Cylinder PSB6X20R the Right Cylinder?
This 6 mm bore provides 10.6 N net push at 0.5 MPa. Stepping down to the Ø4 variant yields 4.1 N, while stepping up to Ø10 offers 29.8 N. Choose this model when your push requirement falls in that lower range. Remember the internal spring sets a 0.2 MPa minimum pressure before motion begins.
Confirm your ordering essentials: 6 mm bore, 20 mm stroke, no magnet, R axial back cover, and any LB, FA, or CJ mount. The thin 3 mm rod handles coaxial thrust well, but add an external guide for off-axis loads.
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 PSB6X20R FAQ
The net push force is 10.6 N at 0.5 MPa and 16.3 N at 0.7 MPa. Because an internal spring opposes the air stroke, a minimum of 0.2 MPa is required before the rod moves. The spring ensures fail-safe retraction upon air loss.
It uses a fixed TPU bumper at each end to decelerate the stroke. It is not adjustable. At higher speeds with real tooling mass, meter-out the exhaust or add an external shock absorber to prevent bottoming out.
