Airtac PSB Single Acting Compact Cylinder PSB6X45SR
The AirTAC Airtac PSB Single Acting Compact Cylinder PSB6X45SR is a single acting, push type (spring return) pen-size mini cylinder with a Ø6mm bore and 45mm 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 PSB6X45SR
The AirTAC PSB6X45SR is a JIS pen-size single-acting push cylinder that extends via one M5x0.8 air port and retracts via an internal spring. It provides 10.6 N of net push at 0.5 MPa and 16.3 N at 0.7 MPa. Because the return spring constantly opposes the air stroke, these figures already reflect the usable force after spring deduction.
Featuring a built-in magnet for position sensing and an axial R back cover, this slim SUS304 stainless body fits tight spaces. The fail-safe design ensures the rod pulls home automatically if air pressure drops. Plan for a safe working load of roughly 6 N, which is about 60 percent of the 0.5 MPa rating, to account for seal friction.
Airtac PSB Single Acting Compact Cylinder PSB6X45SR Technical Specifications
| Model | Airtac PSB Single Acting Compact Cylinder PSB6X45SR |
|---|---|
| Series | PSB JIS pen-size mini cylinder |
| Bore size | Ø6 mm |
| Rod diameter | Ø3 mm |
| Stroke | 45 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 PSB6X45SR Is Used
Small Part Ejector
Pushes lightweight stamped electronics components out of a die on a packaging line, relying on the spring to retract safely when air stops.
Sorting Diverter Gate
Acts as a compact diverter arm on a narrow material handling belt, using the 10.6 N push force to flick small plastic parts into a secondary chute.
Lab Test Clamp
Secures thin glass slides or microfluidic chips during automated fluid dispensing, releasing them instantly upon air exhaust to prevent breakage.
Is the Airtac PSB Single Acting Compact Cylinder PSB6X45SR the Right Cylinder?
When sizing this 6 mm bore unit against adjacent options, stepping down to a 4 mm bore yields just 4.1 N of net push at 0.5 MPa, while moving up to a 10 mm bore provides 29.8 N. Choose this 45 mm stroke model when your application requires low-force actuation with a guaranteed spring-retracted hold.
Remember that the internal spring sets a 0.2 MPa minimum pressure before motion begins. The Ø3 mm rod is built for coaxial thrust, so over this 45 mm stroke add an external linear bearing if side loads are present. Confirm your ordering essentials: bore, stroke, S magnet, R axial inlet, and 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 PSB6X45SR FAQ
The net push force is 10.6 N at 0.5 MPa and 16.3 N at 0.7 MPa. The internal return spring requires a minimum of 0.2 MPa before the rod begins to move. If air loss occurs, the spring pulls the rod back to its fail-safe retracted position.
The -S suffix indicates a built-in piston magnet compatible with AirTAC reed or electronic switches. Cushioning is handled by a fixed TPU bumper that decelerates the rod over the last few millimeters; at high speeds with heavy tooling, meter-out the exhaust or add an external shock absorber.
