Airtac PSBR Single Acting Square Head Compact Cylinder PSBR10X20SU
The AirTAC Airtac PSBR Single Acting Square Head Compact Cylinder PSBR10X20SU is a single acting, push type (spring return) pen-size mini cylinder with direct front-cover mounting (M4×0.7 thread). A single air port drives the push stroke on a Ø10mm bore, 20mm stroke; the return spring resets the rod when air is released.

About the Airtac PSBR Single Acting Square Head Compact Cylinder PSBR10X20SU
The AirTAC PSBR10X20SU is a JIS pen-size single-acting push cylinder with a 10mm bore and 20mm stroke. Air entering the M5x0.8 port extends the rod, while an internal spring retracts it. This fail-safe design ensures the rod returns home on air loss, requiring only one solenoid line. It supplies 29.8N of net push at 0.5 MPa and 45.5N at 0.7 MPa.
You mount it directly via the front-cover M4x0.7 thread, saving space in tight fixtures. The SUS316L stainless barrel resists corrosion in damp environments. A fixed TPU bumper cushions the stroke ends. The built-in magnet (-S) supports reed or electronic switches, and the U back cover provides a 90-degree side inlet for flat plumbing. Plan for a safe working load of about 18N (60% of the 0.5MPa rating) to account for friction.

|---|---|
| Series | PSBR JIS pen-size front-mount cylinder |
| Bore size | Ø10 mm |
| Rod diameter | Ø4 mm |
| Stroke | 20 mm |
| Acting type | Single acting, push type (spring return) |
| Front-mount thread | M4×0.7 |
| Port size | M5×0.8 |
|---|---|
| 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. Front cover carries the mounting thread (M4×0.7); barrel is SUS316L. Forces below are NET spring-deducted values. Confirm against the product label.
Net Push Force (Ø10mm)
| Pressure | Net push force |
|---|---|
| 0.5 MPa | 29.8 N |
| 0.7 MPa (max) | 45.5 N |
These are usable push forces after the return spring is subtracted, 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 PSBR Single Acting Square Head Compact Cylinder PSBR10X20SU Is Used
Part Ejection
Uses the spring-return push to eject small machined parts from a fixture, ensuring the arm safely retracts if air pressure drops.
Panel Pusher
Extends to push a lightweight panel into a test socket, with the direct front mount keeping the overall jig profile extremely slim.
Clamp Release
Applies 29.8N of thrust to open a small packaging clamp, relying on the spring to hold the clamp closed during air loss.
Is the Airtac PSBR Single Acting Square Head Compact Cylinder PSBR10X20SU the Right Cylinder?
For a 10mm bore, this model yields 29.8N net push at 0.5 MPa. Stepping down to an 8mm bore gives 18.7N, while moving up to a 12mm bore provides 42.9N. Size your payload accordingly, keeping in mind the return spring sets a 0.2 MPa minimum pressure before motion begins. The direct front-mount thread simplifies installation without extra brackets.
When ordering, confirm the 20mm stroke fits your travel needs. The 90-degree side inlet (U) helps route tubing in confined spaces. Remember the thin 4mm rod is built for coaxial thrust; if your application involves off-axis loads or longer strokes, add an external guide or linear bearing to prevent side-load damage.
Quick checklist
- ✓ Net push force at your working pressure
- ✓ Bolt directly through the front cover (M4×0.7)
- ✓ Only one air line / solenoid needed
- ✓ Fail-safe retract on air loss
- ✓ Magnet (S) for sensors?
- ✓ Stroke ≤ 60 mm (single-acting limit)
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 Match bolt size and engagement to the front thread.
- check Do not add an external return mechanism.
- check Keep the load coaxial; avoid side load on the thin rod.
Airtac PSBR Single Acting Square Head Compact Cylinder PSBR10X20SU FAQ
The net push force is 29.8N at 0.5 MPa and 45.5N at the 0.7 MPa maximum. Because it is single-acting push with a return spring, it requires a minimum of 0.2 MPa to overcome the spring and extend the rod.
It mounts directly via an M4x0.7 thread on the front cover, eliminating separate brackets. The built-in magnet works with reed or electronic switches for position sensing, and the SUS316L barrel handles damp environments.
