Airtac PSB Single Acting Compact Cylinder PSB10X5SU
The AirTAC Airtac PSB Single Acting Compact Cylinder PSB10X5SU is a single acting, push type (spring return) pen-size mini cylinder with a Ø10mm bore and 5mm 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 PSB10X5SU
The AirTAC PSB10X5SU is a JIS pen-size single-acting push cylinder that extends a Ø4 mm rod via one M5x0.8 air port, relying on a built-in spring to retract automatically. This single-line design cuts tubing complexity and ensures the rod safely pulls back if air pressure drops. It supplies 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 a slim body, it fits tight jigs and light end-of-arm tooling. The U suffix provides a 90-degree side inlet for flat plumbing. A fixed TPU bumper cushions the stroke ends, and the -S magnet supports reed or electronic switches for position sensing.
Airtac PSB Single Acting Compact Cylinder PSB10X5SU Technical Specifications
| Model | Airtac PSB Single Acting Compact Cylinder PSB10X5SU |
|---|---|
| Series | PSB JIS pen-size mini cylinder |
| Bore size | Ø10 mm |
| Rod diameter | Ø4 mm |
| Stroke | 5 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 PSB10X5SU Is Used
Short-Stroke Part Ejection
Uses the 5 mm stroke to kick small machined components out of a fixture quickly, with the spring ensuring the ejector retracts clear on air loss.
Sorting Diverter Gate
Pushes lightweight packages on a packaging line; the fail-safe retract keeps the gate open during an emergency stop to clear the belt path.
Clamp Release Mechanism
Applies 29.8 N of push at 0.5 MPa to hold a thin workpiece, then springs back automatically to release the part when the single solenoid de-energizes.
Is the Airtac PSB Single Acting Compact Cylinder PSB10X5SU the Right Cylinder?
This 10 mm bore generates 29.8 N net push at 0.5 MPa. Stepping down, a 6 mm bore yields 10.6 N, while stepping up to a 12 mm bore provides 42.9 N. Plan for a safe working load of roughly 18 N (about 60 percent of the 0.5 MPa rating) to account for friction. Vertically, it lifts about 1.5 kg with a 2:1 margin.
The internal spring mandates a 0.2-0.7 MPa minimum pressure before motion begins. The slender Ø4 mm rod handles coaxial thrust well but needs an external guide for any off-axis loads. Confirm your ordering essentials: 10 mm bore, 5 mm stroke, S magnet, U side inlet, and mounting bracket.
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 PSB10X5SU FAQ
It delivers 29.8 N of net push at 0.5 MPa and 45.5 N at 0.7 MPa maximum. Because the internal return spring opposes the air stroke, a minimum of 0.2 MPa is required before the rod begins to move, and the spring holds the rod retracted on air loss.
It uses a fixed TPU bumper to decelerate the stroke over the last few millimeters; at higher speeds with real tooling mass, meter-out the exhaust or add an external shock absorber. The -S option includes a built-in piston magnet compatible with AirTAC reed or electronic switches.
