Airtac PSBR Single Acting Square Head Compact Cylinder PSBR12X10SU
The AirTAC Airtac PSBR Single Acting Square Head Compact Cylinder PSBR12X10SU is a single acting, push type (spring return) pen-size mini cylinder with direct front-cover mounting (M5×0.8 thread). A single air port drives the push stroke on a Ø12mm bore, 10mm stroke; the return spring resets the rod when air is released.

About the Airtac PSBR Single Acting Square Head Compact Cylinder PSBR12X10SU
The AirTAC PSBR12X10SU is a JIS pen-size single-acting push cylinder with a 12mm bore and 10mm stroke. It supplies 42.9N of net push at 0.5MPa. A built-in return spring pulls the rod back on air loss, making the unit fail-safe retracted and requiring only one solenoid line. The SUS316L stainless barrel suits damp or washdown environments.
You bolt this actuator straight to a fixture via its direct M5x0.8 front-cover thread, saving space and eliminating extra brackets. Air enters the M5x0.8 port to extend the rod, while a fixed TPU bumper decelerates the last few millimeters of travel. The -S option adds a piston magnet for reed or electronic switches.

|---|---|
| Series | PSBR JIS pen-size front-mount cylinder |
| Bore size | Ø12 mm |
| Rod diameter | Ø5 mm |
| Stroke | 10 mm |
| Acting type | Single acting, push type (spring return) |
| Front-mount thread | M5×0.8 |
| 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 75 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 (M5×0.8); barrel is SUS316L. Forces below are NET spring-deducted values. Confirm against the product label.
Net Push Force (Ø12mm)
| Pressure | Net push force |
|---|---|
| 0.5 MPa | 42.9 N |
| 0.7 MPa (max) | 65.5 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 PSBR12X10SU Is Used
Panel Pusher
Uses the spring-return push stroke to nudge lightweight panels into a fixture, automatically retracting when air cuts out.
Part Ejector
Ejects small machined parts off a belt with 42.9N of force, relying on the fail-safe retract to clear the path on air loss.
Clamp Release
Bolts via the front M5x0.8 thread to release a secondary clamp, using the single solenoid line for simple wiring.
Is the Airtac PSBR Single Acting Square Head Compact Cylinder PSBR12X10SU the Right Cylinder?
This 12mm bore yields 42.9N net push at 0.5MPa (65.5N at the 0.7MPa maximum). If you need less force, the 10mm bore gives 29.8N at 0.5MPa; for heavier duty, the 16mm bore provides 74.8N. Plan for a safe working load of about 26N, which is roughly 60 percent of the 0.5MPa rating, to account for seal friction. It lifts about 2.2kg vertically with a sane 2:1 margin.
The direct front-cover M5x0.8 thread mounts flush to your jig. The U suffix provides a 90-degree side inlet for flat plumbing. The thin 5mm rod handles coaxial thrust, so add an external guide for any off-axis loads. Confirm the 10mm stroke and your switch type before ordering.
Quick checklist
- ✓ Net push force at your working pressure
- ✓ Bolt directly through the front cover (M5×0.8)
- ✓ Only one air line / solenoid needed
- ✓ Fail-safe retract on air loss
- ✓ Magnet (S) for sensors?
- ✓ Stroke ≤ 75 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 PSBR12X10SU FAQ
The net push force is 42.9N at 0.5MPa and 65.5N at the 0.7MPa maximum. The internal return spring sets a 0.2MPa minimum pressure before the rod moves, and the cylinder fails safe retracted on air loss.
The front cover features a direct M5x0.8 mounting thread for straight fixture bolting. The U suffix adds a 90-degree side air inlet, and the S suffix provides a built-in piston magnet for position detection using reed or electronic switches.
