Airtac PSBR Single Acting Square Head Compact Cylinder PSBR12X10R
The AirTAC Airtac PSBR Single Acting Square Head Compact Cylinder PSBR12X10R 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 PSBR12X10R
The AirTAC PSBR12X10R is a JIS pen-size single-acting push cylinder with a 12mm bore and 10mm 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 if air pressure drops. 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 suits damp environments, and a fixed TPU bumper decelerates the rod at stroke ends. Plan for a safe working load of about 26 N (60% of the 0.5 MPa rating) to account for seal friction.

| Model | Airtac PSBR Single Acting Square Head Compact Cylinder PSBR12X10R |
|---|---|
| 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 PSBR12X10R Is Used
Part Ejection
Uses the spring-return push to eject small machined parts from a fixture, guaranteeing the arm retracts safely when air is removed.
Panel Pusher
Bolts directly via the front M5x0.8 thread to push lightweight panels into a locating slot, saving jig space without extra brackets.
Clamp Release
Applies 42.9 N of net push to open a spring-loaded clamp, automatically releasing the workpiece upon air loss for safe unloading.
Is the Airtac PSBR Single Acting Square Head Compact Cylinder PSBR12X10R the Right Cylinder?
This 12mm bore provides 42.9 N net push at 0.5 MPa (65.5 N at 0.7 MPa). If you need less force, the 10mm bore offers 29.8 N at 0.5 MPa; for heavier duty, the 16mm bore yields 74.8 N. The R axial inlet allows inline plumbing, and the direct front mount eliminates extra brackets.
Remember the internal spring sets a 0.2 MPa minimum pressure before motion begins. The thin Ø5 mm rod is built for coaxial thrust, so add an external guide for off-axis loads. This unit has no magnet; order the -S variant if you need position sensing.
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 PSBR12X10R 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 of 0.2 MPa to overcome the spring and extend the rod.
It mounts directly via the M5x0.8 thread on the front cover, eliminating separate brackets. This R-variant features an axial air inlet for inline plumbing, and the SUS316L stainless barrel resists moisture.
