Airtac PSBR Single Acting Square Head Compact Cylinder PSBR12X60U
The AirTAC Airtac PSBR Single Acting Square Head Compact Cylinder PSBR12X60U 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, 60mm stroke; the return spring resets the rod when air is released.

About the Airtac PSBR Single Acting Square Head Compact Cylinder PSBR12X60U
The AirTAC PSBR12X60U is a single-acting push pen cylinder that extends via one M5x0.8 air port and retracts via an internal spring. It supplies about 42.9 N of net push at 0.5 MPa, rising to 65.5 N at the 0.7 MPa maximum. The fail-safe spring holds the rod retracted on air loss, simplifying wiring to one solenoid line.
You bolt this 12mm bore unit straight to a jig using the direct M5x0.8 front-cover thread. The SUS316L stainless barrel suits damp environments, while a fixed TPU bumper cushions the stroke ends. Plan for a safe working load of roughly 26 N, which accounts for seal friction and smooth travel.

| Series | PSBR JIS pen-size front-mount cylinder |
| Bore size | Ø12 mm |
| Rod diameter | Ø5 mm |
| Stroke | 60 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 PSBR12X60U Is Used
Part Ejector
Pushes machined pins out of a chuck using 42.9 N of thrust, with the spring pulling the rod back safely when air drops.
Panel Pusher
Cycles a light guard into place via the direct M5x0.8 front thread, fitting neatly into tight assembly jigs.
Clamp Release
Overrides a mechanical latch to free a workpiece, relying on the fail-safe retract to reset the mechanism.
Is the Airtac PSBR Single Acting Square Head Compact Cylinder PSBR12X60U the Right Cylinder?
This 12mm bore provides 42.9 N net push at 0.5 MPa. If you need less force, the 10mm bore yields 29.8 N; if you need more, the 16mm bore provides 74.8 N. The internal return spring sets a 0.2 MPa minimum pressure before motion begins.
The direct M5x0.8 front-mount thread eliminates separate brackets. This U variant features a 90-degree side inlet for flat plumbing. Confirm your load stays coaxial, as the 5mm rod needs an external guide for off-axis stress over the 60mm stroke.
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 PSBR12X60U FAQ
It delivers 42.9 N net push at 0.5 MPa and 65.5 N at 0.7 MPa maximum. Because an internal spring retracts the rod, a 0.2 MPa minimum pressure is required to overcome the spring before extension.
It mounts directly via an M5x0.8 thread on the front cover, requiring no separate bracket. The barrel is made of SUS316L stainless steel for corrosion resistance, and this model does not include a sensor magnet.
