Airtac PSB Single Acting Compact Cylinder PSB10X40SR
The AirTAC Airtac PSB Single Acting Compact Cylinder PSB10X40SR 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 PSB10X40SR
The AirTAC PSB10X40SR is a JIS pen-size single-acting push cylinder that extends via one M5x0.8 air port and retracts via a built-in return spring. It delivers 29.8 N of net push at 0.5 MPa, providing a fail-safe retracted state whenever air pressure drops. This single-line design cuts tubing and valving costs compared to double-acting units.
Built with a SUS304 stainless steel rod and barrel, the slim mini body fits tight jigs and damp environments. The 4 mm rod handles coaxial thrust, while the fixed TPU bumper cushions the last few millimeters of travel. Plan for a safe working load of about 18 N (roughly 60 percent of the 0.5 MPa rating) to account for seal friction.
Airtac PSB Single Acting Compact Cylinder PSB10X40SR Technical Specifications
| Model | Airtac PSB Single Acting Compact Cylinder PSB10X40SR |
|---|---|
| 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 PSB10X40SR Is Used
Part Ejector
Pushes stamped metal parts off a conveyor line. The spring-return design ensures the ejector arm safely pulls back if the main air supply fails.
Carton Flap Folder
Extends to fold small cardboard flaps during case packing. Its compact pen-size body slides easily into tight packaging machinery frames.
Clamp Release
Applies 18 N of safe holding force to secure light components on an assembly jig. Exhausting the air automatically retracts the clamp for quick unloading.
Is the Airtac PSB Single Acting Compact Cylinder PSB10X40SR 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 you need less force, the 6 mm bore offers 10.6 N at 0.5 MPa; for heavier tasks, the 12 mm bore yields 42.9 N. The internal spring requires a minimum of 0.2 MPa before the rod moves and automatically pulls the rod home on air loss.
When ordering, confirm the 40 mm stroke, the S suffix for the piston magnet (compatible with reed or electronic switches), the R axial inlet, and your mounting bracket. For vertical lifts, expect to raise about 1.5 kg safely using a 2:1 margin. Because the 4 mm rod is slender over a 40 mm stroke, add an external linear guide for any off-axis loads.
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 PSB10X40SR FAQ
It provides 29.8 N of net push 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 also guarantees a fail-safe retracted position upon air loss.
The S suffix indicates a built-in piston magnet for use with AirTAC reed or electronic switches. Cushioning relies on a fixed TPU bumper at each end that decelerates the last few millimeters of travel. For high-speed cycles with heavy tooling, meter-out the exhaust or add an external shock absorber.
