Airtac PSBR Single Acting Square Head Compact Cylinder PSBR12X15U
The AirTAC Airtac PSBR Single Acting Square Head Compact Cylinder PSBR12X15U 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 PSBR12X15U
The AirTAC PSBR12X15U 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. This fail-safe design ensures the rod returns home on air loss. It delivers 42.9N net push at 0.5 MPa and 65.5N at 0.7 MPa.
The DIRECT front-cover M5x0.8 thread bolts straight to your fixture, saving space without extra brackets. The SUS316L stainless barrel resists corrosion in damp environments. A fixed TPU bumper cushions the stroke ends.

|---|---|
| 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 PSBR12X15U Is Used
Part Ejector
Pushes light machined parts off a conveyor line with 42.9N net force, retracting automatically when air stops.
Panel Pusher
Extends to index thin electronic panels using the direct front-cover thread for tight jig integration.
Clamp Release
Overcomes a spring-loaded clamp to release a workpiece, returning to a safe retracted state on air loss.
Is the Airtac PSBR Single Acting Square Head Compact Cylinder PSBR12X15U the Right Cylinder?
This 12mm bore provides 42.9N net push at 0.5 MPa. If you need less force, the 10mm bore offers 29.8N; for more power, the 16mm bore yields 74.8N. The internal return spring sets a 0.2 MPa minimum pressure before motion begins. The U back cover provides a 90-degree side air inlet for flat plumbing.
The slim Ø5mm rod handles coaxial thrust well, but add an external guide for off-axis loads. This model lacks a sensor magnet. Confirm the direct front-cover M5x0.8 mounting thread matches your bolt size and engagement depth.
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 PSBR12X15U FAQ
The net push force is 42.9N at 0.5 MPa and 65.5N at 0.7 MPa. The internal return spring requires a minimum of 0.2 MPa before the rod extends. The rod fail-safe retracts on air loss.
It mounts directly via the front-cover M5x0.8 thread. The U back cover features a 90-degree side air inlet port (also M5x0.8) for flat routing. The SUS316L barrel suits damp environments.
