Airtac PSB Single Acting Compact Cylinder PSB10X50R
The AirTAC Airtac PSB Single Acting Compact Cylinder PSB10X50R is a single acting, push type (spring return) pen-size mini cylinder with a Ø10mm bore and 50mm 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 PSB10X50R
The AirTAC PSB10X50R is a JIS pen-size single-acting push cylinder with a 50 mm stroke. Air entering the 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. It provides 29.8 N of net push at 0.5 MPa and 45.5 N at 0.7 MPa.
Because the return spring constantly opposes the air stroke, a minimum operating pressure of 0.2 MPa is required before motion begins. The SUS304 stainless barrel and slim body fit easily into tight jigs. A fixed TPU bumper cushions the stroke ends, and the R axial inlet keeps plumbing perfectly in line. Plan for a safe working load of about 18 N, which accounts for seal friction and smooth travel.
Airtac PSB Single Acting Compact Cylinder PSB10X50R Technical Specifications
| Model | Airtac PSB Single Acting Compact Cylinder PSB10X50R |
|---|---|
| Series | PSB JIS pen-size mini cylinder |
| Bore size | Ø10 mm |
| Rod diameter | Ø4 mm |
| Stroke | 50 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 PSB10X50R Is Used
Part Ejector
Pushes finished metal parts off a machining fixture; the spring safely pulls the rod back if the air supply fails.
Gate Diverter
Acts as a lightweight sorting gate on a packaging line, extending to redirect items and retracting to allow normal flow.
Clamp Release
Holds a workpiece by extending a pin; removing air pressure instantly retracts the pin to free the component.
Is the Airtac PSB Single Acting Compact Cylinder PSB10X50R 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 output to 10.6 N, whereas moving up to a 12 mm bore raises it to 42.9 N. The internal spring holds the rod retracted without live air, making it ideal for clamp-release or part-eject duties. Remember the spring sets a 0.2 MPa minimum pressure before the rod moves. When ordering, confirm the 50 mm stroke, the R axial inlet, and whether you need an LB, FA, or CJ 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 PSB10X50R 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 returns the rod, a minimum operating pressure of 0.2 MPa is required to overcome the spring and move the piston.
It uses a fixed TPU bumper at each end to decelerate the stroke over the last few millimeters. The bumper is not adjustable. At higher speeds with heavy tooling mass, meter-out the exhaust or add an external shock absorber to prevent bottoming out.
