Airtac PSBR Single Acting Square Head Compact Cylinder PSBR12X15SR
The AirTAC Airtac PSBR Single Acting Square Head Compact Cylinder PSBR12X15SR 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, 15mm stroke; the return spring resets the rod when air is released.

About the Airtac PSBR Single Acting Square Head Compact Cylinder PSBR12X15SR
The AirTAC PSBR12X15SR is a JIS pen-size single-acting push cylinder with a 12mm bore and 15mm stroke. Air entering the M5x0.8 port extends the rod, while an internal spring retracts it on air release. This fail-safe design ensures the rod returns home if pressure drops. It delivers 42.9 N of net push at 0.5 MPa, with the spring force already deducted.
You mount this actuator directly via its front-cover M5x0.8 thread, saving space in tight assemblies. The SUS316L stainless barrel resists corrosion in damp environments. A built-in magnet (-S) supports reed or electronic switches for position sensing. The fixed TPU bumper decelerates the rod near the stroke ends. Plan for a safe working load of about 26 N, which is roughly 60 percent of the 0.5 MPa rating, to account for seal friction.
Airtac PSBR Single Acting Square Head Compact Cylinder PSBR12X15SR Technical Specifications
| Model | Airtac PSBR Single Acting Square Head Compact Cylinder PSBR12X15SR |
|---|---|
| Series | PSBR JIS pen-size front-mount cylinder |
| Bore size | Ø12 mm |
| Rod diameter | Ø5 mm |
| Stroke | 15 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 PSBR12X15SR Is Used
Short-Stroke Part Ejector
Pushes lightweight machined parts off a conveyor line using 42.9 N net force, with the spring safely retracting the rod when air is cut.
Panel Push-off Station
Uses the direct M5x0.8 front-mount thread to bolt directly into a tight jig, extending 15mm to separate thin electronic panels.
Clamp Release Mechanism
Applies targeted push force to disengage a holding clamp, relying on the fail-safe spring return to reset the tooling instantly.
Is the Airtac PSBR Single Acting Square Head Compact Cylinder PSBR12X15SR the Right Cylinder?
This 12mm bore provides 42.9 N net push at 0.5 MPa and 65.5 N at the 0.7 MPa maximum. If you need less force, the 10mm bore offers 29.8 N at 0.5 MPa. For heavier tasks, the 16mm bore yields 74.8 N at 0.5 MPa. The internal spring sets a 0.2 MPa minimum pressure before motion begins.
The direct front-cover M5x0.8 thread simplifies fixture mounting without extra brackets. The R axial inlet keeps plumbing in-line. With a 15mm stroke, the Ø5 mm rod handles coaxial thrust well, but avoid side loads. The spring holds the rod retracted safely on air loss. Confirm your port size and thread engagement 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 PSBR12X15SR FAQ
It provides 42.9 N net push at 0.5 MPa and 65.5 N at 0.7 MPa maximum. The internal return spring requires a minimum 0.2 MPa air pressure to extend the rod, and the cylinder fails safely retracted on air loss.
It mounts directly via the front-cover M5x0.8 thread. The -S suffix indicates a built-in piston magnet compatible with reed or electronic switches. The SUS316L stainless barrel provides excellent corrosion resistance.
