Airtac PSB Single Acting Compact Cylinder PSB10X20SCB
The AirTAC Airtac PSB Single Acting Compact Cylinder PSB10X20SCB is a single acting, push type (spring return) pen-size mini cylinder with a Ø10mm bore and 20mm 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 PSB10X20SCB
The AirTAC PSB10X20SCB is a JIS pen-size single-acting push cylinder with a 10 mm bore and 20 mm stroke. Air entering the single M5x0.8 port extends the Ø4 mm rod, while an internal spring ensures fail-safe retraction upon exhaust. You gain simplified valving and tubing since only one solenoid line is necessary. This stainless steel unit provides 29.8 N of net push at 0.5 MPa.
It includes a built-in piston magnet for position sensing and a CB double clevis back cover for pivoting loads. A fixed TPU bumper cushions the stroke ends. For practical sizing, plan for a safe working load of roughly 18 N, which accounts for seal friction and smooth travel.
Airtac PSB Single Acting Compact Cylinder PSB10X20SCB Technical Specifications
| Model | Airtac PSB Single Acting Compact Cylinder PSB10X20SCB |
|---|---|
| Series | PSB JIS pen-size mini cylinder |
| Bore size | Ø10 mm |
| Rod diameter | Ø4 mm |
| Stroke | 20 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 PSB10X20SCB Is Used
Part Ejection Arm
Pushes finished metal stamps off a machining bed; the spring safely pulls the ejector pin back if the air supply drops.
Pivoting Diverter Gate
Uses the CB double clevis to swing a lightweight guide flap, routing small plastic parts down a secondary packaging lane.
Clamp Release Mechanism
Applies 29.8 N of thrust to hold a thin composite sheet, automatically releasing tension when the single solenoid de-energizes.
Is the Airtac PSB Single Acting Compact Cylinder PSB10X20SCB the Right Cylinder?
This 10 mm bore yields 29.8 N net push at 0.5 MPa and 45.5 N at 0.7 MPa. If your task needs less force, stepping down to the Ø6 model provides 10.6 N at 0.5 MPa; moving up to the Ø12 bore offers 42.9 N. Remember the internal spring sets a 0.2 MPa minimum pressure before motion begins. The thin Ø4 mm rod handles coaxial thrust well, but add an external guide if facing off-axis loads over this 20 mm stroke.
When ordering, confirm the 10 mm bore, 20 mm stroke, S magnet for electronic or reed switches, and the CB double clevis mount. The fixed TPU bumper adequately decelerates light tooling, yet meter-out the exhaust or add an external shock absorber if cycling rapidly with heavier masses.
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 PSB10X20SCB FAQ
The net usable 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 before the piston moves.
The S suffix indicates a built-in piston magnet compatible with AirTAC reed or electronic switches. Cushioning relies on a fixed TPU bumper at each end, which decelerates the last few millimeters of travel but is not adjustable.
