Airtac PSB Single Acting Compact Cylinder PSB10X45CB
The AirTAC Airtac PSB Single Acting Compact Cylinder PSB10X45CB is a single acting, push type (spring return) pen-size mini cylinder with a Ø10mm 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 PSB10X45CB
The AirTAC PSB10X45CB is a JIS pen-size single-acting push cylinder with a 45 mm stroke. Air entering the single M5x0.8 port extends the Ø4 mm rod, while an internal spring retracts it upon exhaust release. This fail-safe design ensures the rod returns home if air pressure drops, needing only one solenoid line for simpler tubing. It supplies 29.8 N of net push at 0.5 MPa.
Built with a SUS304 stainless barrel and a CB double clevis back cover, this slim mini body suits pivoting loads in tight jigs. The fixed TPU bumper decelerates the stroke at each end. For a 45 mm extension, the thin rod handles coaxial thrust well, but add an external guide for any off-axis loads to prevent side-load damage.
Airtac PSB Single Acting Compact Cylinder PSB10X45CB Technical Specifications
| Model | Airtac PSB Single Acting Compact Cylinder PSB10X45CB |
|---|---|
| Series | PSB JIS pen-size mini cylinder |
| Bore size | Ø10 mm |
| Rod diameter | Ø4 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 (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 PSB10X45CB Is Used
Pivoting Part Ejector
Uses the CB double clevis to swing rejected components off a conveyor belt, relying on the spring to retract the pin safely during an air loss event.
Carton Flap Folder
Pushes small cardboard flaps down on a packaging line, where the single air line lowers pneumatic complexity and the fail-safe return prevents jams.
Light Duty Gate Actuator
Opens a small diverter gate on a factory sorter, with the fixed TPU bumper softening the impact at the end of the 45 mm travel.
Is the Airtac PSB Single Acting Compact Cylinder PSB10X45CB the Right Cylinder?
Selecting the PSB10X45CB gives 29.8 N net push at 0.5 MPa and 45.5 N at the 0.7 MPa maximum. If your task needs less force, the Ø6 bore yields 10.6 N; for heavier work, the Ø12 bore provides 42.9 N. A built-in spring sets a 0.2 MPa minimum pressure before motion begins. Plan for a safe working load of about 18 N, which is roughly 60 percent of the 0.5 MPa rating.
The CB double clevis accommodates pivoting articulation. When ordering, confirm the 10 mm bore, 45 mm stroke, and your mounting bracket. This unit lacks a sensor magnet; choose the -S suffix if you require position detection.
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 PSB10X45CB 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 extends. The spring automatically retracts the rod if air is removed.
No. Without continuous air pressure, the return spring pulls the rod fully back to the retracted position. It is not a locking brake. Additionally, the fixed TPU bumper only decelerates the last few millimeters of travel, so meter-out the exhaust or add an external shock absorber when moving heavy tooling mass at higher speeds.
