Airtac PSBR Single Acting Square Head Compact Cylinder PSBR12X60SU
The AirTAC Airtac PSBR Single Acting Square Head Compact Cylinder PSBR12X60SU 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 PSBR12X60SU
The AirTAC PSBR12X60SU is a JIS pen-size single-acting push cylinder with a 12mm bore and 60mm 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, requiring only one solenoid line. It supplies 42.9 N of net push at 0.5 MPa and 65.5 N at 0.7 MPa.
The body features a SUS316L stainless barrel for durability in damp environments. You mount it directly via the front-cover M5x0.8 thread, saving space in tight jigs. A fixed TPU bumper decelerates the stroke, and the built-in magnet (-S) works with reed or electronic switches. The U back cover provides a 90-degree side inlet for flat plumbing.

| 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 PSBR12X60SU Is Used
Panel Pusher
Uses the 42.9 N push stroke to index light panels on a line, with the fail-safe spring retracting the rod if air drops.
Part Eject
Pushes small machined parts off a conveyor belt; the direct front mount bolts straight to the machine frame.
Clamp Release
Extends to unseat a holding clamp, relying on the internal spring to withdraw the 5mm rod for safe reset.
Is the Airtac PSBR Single Acting Square Head Compact Cylinder PSBR12X60SU the Right Cylinder?
This 12mm bore provides 42.9 N net push at 0.5 MPa. If sizing down, the 10mm bore yields 29.8 N; if sizing up, the 16mm bore yields 74.8 N. Plan for a safe working load of about 26 N (roughly 60 percent of the 0.5 MPa rating) to account for seal friction. This equates to lifting about 2.2 kg vertically with a 2:1 margin.
The internal return spring sets a 0.2 MPa minimum pressure before motion begins. The direct front-cover thread eliminates brackets, and the fail-safe spring holds the rod retracted. The 5mm rod is built for coaxial thrust, so add an external guide for off-axis loads over this 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 PSBR12X60SU FAQ
The net push force is 42.9 N at 0.5 MPa and 65.5 N at 0.7 MPa. Because it is spring-return, the internal spring sets a 0.2 MPa minimum pressure before the rod moves. The rod fails safe to the retracted position on air loss.
It mounts directly via the front-cover M5x0.8 thread. The U back cover provides a 90-degree side air inlet. The built-in -S magnet works with AirTAC reed or electronic switches for position detection.
