Airtac PSB Single Acting Compact Cylinder PSB10X40CB
The AirTAC Airtac PSB Single Acting Compact Cylinder PSB10X40CB 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 PSB10X40CB
The AirTAC PSB10X40CB is a JIS pen-size single-acting push cylinder with a 10 mm bore and 40 mm stroke. Air entering the M5x0.8 port extends the Ø4 mm rod, while an internal spring retracts it on exhaust. This fail-safe design ensures the rod returns home if air pressure drops. The CB double clevis back cover accommodates pivoting loads. You get 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 slim body, it fits tight jigs. A fixed TPU bumper cushions the stroke ends. Plan for a safe working load of roughly 18 N, which is about 60 percent of the 0.5 MPa rating. This accounts for seal friction and smooth travel. It can also lift about 1.5 kg vertically with a sane 2:1 margin.
Airtac PSB Single Acting Compact Cylinder PSB10X40CB Technical Specifications
| Model | Airtac PSB Single Acting Compact Cylinder PSB10X40CB |
|---|---|
| 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 PSB10X40CB Is Used
Pivoting Part Ejector
Uses the CB double clevis to swing and push finished metal parts off a machining center conveyor, relying on the spring to retract safely during air loss.
Carton Flap Folder
Extends to fold light cardboard flaps on a packaging line, with the fail-safe return preventing jams if the pneumatic supply stops.
Diverter Gate Actuator
Pushes a lightweight routing gate to sort small items on a logistics belt, benefiting from the slim stainless body in cramped spaces.
Is the Airtac PSB Single Acting Compact Cylinder PSB10X40CB the Right Cylinder?
This 10 mm bore yields 29.8 N net push at 0.5 MPa. Stepping down to a 6 mm bore drops the force to 10.6 N, while moving up to a 12 mm bore raises it to 42.9 N. The internal spring requires a minimum 0.2 MPa operating pressure before motion begins. The thin Ø4 mm rod handles coaxial thrust well, but over this 40 mm stroke you should add an external guide for any off-axis loads.
Confirm your ordering essentials: 10 mm bore, 40 mm stroke, no magnet, CB double clevis back cover, and any required mounting bracket. The fixed TPU bumper decelerates the last few millimeters of travel, so meter-out the exhaust or add an external shock absorber if cycling quickly with heavy tooling.
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 PSB10X40CB FAQ
The net push force is 29.8 N at 0.5 MPa and 45.5 N at 0.7 MPa. Because an internal spring opposes the air stroke, a minimum pressure of 0.2 MPa is required before the rod moves, and the spring retracts the rod on air loss.
It uses a fixed TPU bumper at each end to decelerate the last few millimeters of travel, which is not adjustable. The CB back cover provides a double clevis for pivoting loads, and this model lacks a sensor magnet.
