Airtac PSB Single Acting Compact Cylinder PSB10X45U
The AirTAC Airtac PSB Single Acting Compact Cylinder PSB10X45U 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 PSB10X45U
The AirTAC PSB10X45U is a single-acting push pen cylinder that extends via one M5x0.8 air port and relies on an internal spring to retract. It supplies 29.8 N of net push at 0.5 MPa, reaching 45.5 N at the 0.7 MPa maximum. The U option provides a 90-degree side inlet for flat plumbing in confined spaces.
Built with a SUS304 stainless rod and barrel, this slim mini body handles tight, damp jigs. A fixed TPU bumper cushions the stroke ends. For real-world planning, target a safe working load of roughly 18 N. If lifting vertically, expect to move about 1.5 kg with a sane 2:1 margin.
Airtac PSB Single Acting Compact Cylinder PSB10X45U Technical Specifications
| Model | Airtac PSB Single Acting Compact Cylinder PSB10X45U |
|---|---|
| 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 PSB10X45U Is Used
Part Ejector
Pushes machined pins off a conveyor line; the spring safely pulls the retracted rod home when air drops.
Flap Folder
Extends to tuck carton flaps on a packaging line, using the 90-degree side inlet to keep tubing flat against the frame.
Clamp Release
Applies 29.8 N of thrust to hold a light workpiece, then releases instantly when the single solenoid exhausts.
Is the Airtac PSB Single Acting Compact Cylinder PSB10X45U the Right Cylinder?
This 10 mm bore generates 29.8 N net push at 0.5 MPa. Stepping down, the Ø6 bore yields 10.6 N; stepping up, the Ø12 bore provides 42.9 N. The internal spring sets a 0.2 MPa minimum pressure before motion begins and guarantees a fail-safe retract on air loss. The Ø4 mm rod is built for coaxial thrust, so over this 45 mm stroke or any off-axis load, add an external linear bearing to prevent side-load damage.
Confirm your ordering essentials: 10 mm bore, 45 mm stroke, no magnet, U side inlet, and your preferred mounting bracket. The fixed TPU bumper only decelerates the last few millimeters, so at higher speeds with real tooling mass, meter-out the exhaust or add an external shock absorber.
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 PSB10X45U FAQ
It delivers 29.8 N net push at 0.5 MPa and 45.5 N at 0.7 MPa maximum. Because the internal spring opposes the stroke, a minimum of 0.2 MPa is required before the rod moves. Loss of air causes a fail-safe retract.
Air to one port extends the rod, while exhaust allows the spring to retract it. The fixed TPU bumper decelerates the last few millimeters of travel but is not a lock. At high speeds with heavy tooling, meter-out the exhaust or use an external shock absorber.
