Airtac PSB Single Acting Compact Cylinder PSB10X40SCB
The AirTAC Airtac PSB Single Acting Compact Cylinder PSB10X40SCB is a single acting, push type (spring return) pen-size mini cylinder with a Ø10mm bore and 40mm 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 PSB10X40SCB
The AirTAC PSB10X40SCB is a JIS pen-size single-acting push cylinder with a 10 mm bore and 40 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, needing only one solenoid line for simpler tubing. It provides 29.8 N of net push at 0.5 MPa and 45.5 N at 0.7 MPa.
Built with a SUS304 stainless barrel and rod, the slim mini body fits tight jigs and light end-of-arm tooling. The CB double clevis accommodates pivoting loads, and the built-in magnet (-S) supports reed or electronic switches. For practical sizing, plan for a safe working load of about 18 N (roughly 60% of the 0.5 MPa rating), which can vertically lift around 1.5 kg with a 2:1 margin.
Airtac PSB Single Acting Compact Cylinder PSB10X40SCB Technical Specifications
| Model | Airtac PSB Single Acting Compact Cylinder PSB10X40SCB |
|---|---|
| Series | PSB JIS pen-size mini cylinder |
| Bore size | Ø10 mm |
| Rod diameter | Ø4 mm |
| Stroke | 40 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 PSB10X40SCB Is Used
Part Ejector
Pushes lightweight stamped parts off a conveyor belt; the spring safely pulls the rod back if the air supply fails.
Carton Flap Folder
Extends to fold small cardboard flaps during case packing, using the CB clevis to pivot smoothly with the mechanism.
Clamp Release
Acts as a fail-safe clamp release on a light assembly fixture, defaulting to an open position upon air loss.
Is the Airtac PSB Single Acting Compact Cylinder PSB10X40SCB the Right Cylinder?
This 10 mm bore yields 29.8 N net push at 0.5 MPa. If your task needs less force, the Ø6 model offers 10.6 N; for heavier pushes, the Ø12 provides 42.9 N. Remember the internal spring sets a 0.2 MPa minimum pressure before motion begins, and the rod stays retracted without live air. The fixed TPU bumper decelerates the last few millimeters of travel, but with real tooling mass at mid-to-high speed, meter-out the exhaust or add an external shock absorber.
When ordering, verify your stroke (40 mm here, within the 60 mm single-acting limit), the -S magnet for sensing, and the CB double clevis mount. Because the Ø4 mm rod is slender, use an external guide or linear bearing over this 40 mm stroke to prevent off-axis side 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 PSB10X40SCB FAQ
The net usable push force is 29.8 N at 0.5 MPa and 45.5 N at the 0.7 MPa maximum. Because an internal spring returns the rod, a minimum pressure of 0.2 MPa is required before the piston moves, and the rod fails safe to the retracted position on air loss.
The -S suffix indicates a built-in piston magnet compatible with reed or electronic switches. Cushioning is handled by a fixed TPU bumper at each end; it is not adjustable, so for heavy tooling mass at higher speeds, you should meter-out the exhaust or add an external shock absorber.
