Airtac PSBR Single Acting Square Head Compact Cylinder PSBR12X10SR
The AirTAC Airtac PSBR Single Acting Square Head Compact Cylinder PSBR12X10SR 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 PSBR12X10SR
The AirTAC PSBR12X10SR is a JIS pen-size single-acting push cylinder with a built-in magnet and axial R back cover inlet. Feeding air to the M5x0.8 port extends the rod, while an internal spring retracts it automatically. This fail-safe design ensures the rod returns home on air loss, requiring only one solenoid line. It delivers 42.9 N of net push at 0.5 MPa.
The direct M5x0.8 front-cover mounting thread bolts straight to your fixture, saving space in tight jigs. The SUS316L stainless barrel shrinks the footprint for light end-of-arm tooling. A fixed TPU bumper cushions the stroke ends. For real-world sizing, plan for a safe working load of about 26 N (roughly 60 percent of the 0.5 MPa rating) to account for seal friction.

|---|---|
| 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 PSBR12X10SR Is Used
Short-Stroke Part Ejector
Uses the 10 mm extension to push small finished parts out of a machining chuck reliably on air release.
Panel Push-off Mechanism
Bolts via the front M5x0.8 thread to eject thin electronic panels from a test socket without lateral stress.
Fail-Safe Clamp Release
Applies spring-retracted holding force that safely releases a delicate workpiece if the pneumatic air supply drops.
Is the Airtac PSBR Single Acting Square Head Compact Cylinder PSBR12X10SR the Right Cylinder?
This 12 mm bore provides 42.9 N net push at 0.5 MPa and 65.5 N at the 0.7 MPa maximum. If your payload is lighter, the 10 mm bore version offers 29.8 N at 0.5 MPa. For heavier tooling, the 16 mm bore yields 74.8 N. The internal spring sets a 0.2 MPa minimum pressure before motion begins. The built-in magnet supports reed or electronic switches for position sensing.
The direct front-cover M5x0.8 thread handles mounting without extra brackets. The axial R back cover inlet keeps plumbing in-line. The thin Ø5 mm rod is built for coaxial thrust, so over the 10 mm stroke or under off-axis loads, add an external guide to prevent side load. The fixed TPU bumper only decelerates the last few mm, so meter-out the exhaust if moving real mass at higher speeds.
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 PSBR12X10SR FAQ
The net push force is 42.9 N at 0.5 MPa and 65.5 N at the 0.7 MPa maximum. Because it is single-acting push with a return spring, it requires a minimum pressure of 0.2 MPa to overcome the spring before the rod moves.
It mounts directly via the M5x0.8 front-cover thread. On air loss, the internal spring holds the rod retracted in a fail-safe home position, but it is not a mid-position lock or brake. The SUS316L barrel provides corrosion resistance.
