Airtac PSB Single Acting Compact Cylinder PSB10X40R
The AirTAC Airtac PSB Single Acting Compact Cylinder PSB10X40R 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 PSB10X40R
The AirTAC PSB10X40R is a JIS pen-size single-acting push cylinder with a 40 mm stroke. Air entering the M5x0.8 port extends the Ø4 mm rod, while an internal spring retracts it upon exhaust release. This fail-safe retracted state secures your tooling during air loss. The slim SUS304 stainless body fits tight jigs, and the unit delivers 29.8 N of net push at 0.5 MPa.
Because the return spring constantly opposes air pressure, a minimum of 0.2 MPa is required before motion begins. The fixed TPU bumper decelerates the rod over the last few millimeters of travel. Need pulling action instead? Choose the PTB series; for force in both directions without spring loss, select the double-acting PB cylinder.
Airtac PSB Single Acting Compact Cylinder PSB10X40R Technical Specifications
| Model | Airtac PSB Single Acting Compact Cylinder PSB10X40R |
|---|---|
| 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 PSB10X40R Is Used
Part Ejector
Pushes light machined components off a conveyor belt; the spring safely pulls the rod back if the airline drops.
Flap Folder
Extends to fold carton flaps on a packaging line, relying on the fail-safe retract to clear the path for the next box.
Clamp Release
Applies 29.8 N of push at 0.5 MPa to hold a small workpiece, automatically releasing pressure when air is removed.
Is the Airtac PSB Single Acting Compact Cylinder PSB10X40R the Right Cylinder?
This 10 mm bore provides 29.8 N net push at 0.5 MPa and 45.5 N at 0.7 MPa. If sizing adjacent models, the Ø6 bore yields 10.6 N at 0.5 MPa, while the Ø12 bore offers 42.9 N at 0.5 MPa. Plan for a safe working load of roughly 18 N, which is about 60 percent of the 0.5 MPa figure, to account for seal friction.
The internal spring ensures the rod retracts safely on air loss, but remember the thin Ø4 mm rod is built for coaxial thrust. Over this 40 mm stroke, add an external guide for any off-axis loads. Confirm your ordering essentials: 10 mm bore, 40 mm stroke, no magnet, R axial inlet, and standard mounting.
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 PSB10X40R FAQ
It provides a net push of 29.8 N at 0.5 MPa and 45.5 N at 0.7 MPa. Because the internal spring opposes motion, a minimum pressure of 0.2 MPa is required to extend the rod. The spring ensures fail-safe retraction upon air loss.
This model uses a fixed TPU bumper to decelerate the rod over the last few millimeters of travel; it is not an adjustable shock absorber. At higher speeds with real tooling mass, meter-out the exhaust. This specific unit does not include a sensor magnet.
