Airtac PSBR Single Acting Square Head Compact Cylinder PSBR10X25SU
The AirTAC Airtac PSBR Single Acting Square Head Compact Cylinder PSBR10X25SU is a single acting, push type (spring return) pen-size mini cylinder with direct front-cover mounting (M4×0.7 thread). A single air port drives the push stroke on a Ø10mm bore, 25mm stroke; the return spring resets the rod when air is released.

About the Airtac PSBR Single Acting Square Head Compact Cylinder PSBR10X25SU
The AirTAC PSBR10X25SU is a JIS pen-size single-acting push cylinder with a 10 mm bore and 25 mm 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 air pressure drops. It delivers 29.8 N of net push at 0.5 MPa.
The direct M4x0.7 front-cover mounting thread bolts straight to your fixture, saving space in compact assemblies. The SUS316L stainless barrel resists corrosion in damp environments, and a fixed TPU bumper cushions the stroke ends.

|---|---|
| Series | PSBR JIS pen-size front-mount cylinder |
| Bore size | Ø10 mm |
| Rod diameter | Ø4 mm |
| Stroke | 25 mm |
| Acting type | Single acting, push type (spring return) |
| Front-mount thread | M4×0.7 |
| 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 60 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 (M4×0.7); barrel is SUS316L. Forces below are NET spring-deducted values. Confirm against the product label.
Net Push Force (Ø10mm)
| Pressure | Net push force |
|---|---|
| 0.5 MPa | 29.8 N |
| 0.7 MPa (max) | 45.5 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 PSBR10X25SU Is Used
Part Ejector
Pushes machined pins out of a fixture using 29.8 N of net force, with the spring safely retracting the rod when air is removed.
Panel Separator
Direct M4x0.7 front-mount thread secures the slim body between conveyor belts to push thin panels onto a diverter lane.
Clamp Release
Overcomes a light holding mechanism to release a clamped component, relying on the fail-safe retract to reset the tooling.
Is the Airtac PSBR Single Acting Square Head Compact Cylinder PSBR10X25SU the Right Cylinder?
When sizing this single-acting push model, compare the net forces of adjacent bores. Dropping to an 8 mm bore yields 18.7 N at 0.5 MPa, while stepping up to a 12 mm bore provides 42.9 N. The PSBR10X25SU sits comfortably in the middle at 29.8 N, making it ideal for moderate ejection tasks.
Remember the internal return spring sets a 0.2 MPa minimum pressure before motion begins. The direct front-mount thread simplifies installation, and the U suffix provides a 90-degree side inlet for flat plumbing. Confirm the M4x0.7 thread engagement on your fixture before ordering.
Quick checklist
- ✓ Net push force at your working pressure
- ✓ Bolt directly through the front cover (M4×0.7)
- ✓ Only one air line / solenoid needed
- ✓ Fail-safe retract on air loss
- ✓ Magnet (S) for sensors?
- ✓ Stroke ≤ 60 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 PSBR10X25SU FAQ
The net push force is 29.8 N at 0.5 MPa and 45.5 N at 0.7 MPa. Because it is single-acting push with a return spring, it requires a minimum pressure of 0.2 MPa to overcome the spring and extend the rod.
It mounts directly via an M4x0.7 thread on the front cover, eliminating extra brackets. The S suffix indicates a built-in piston magnet, allowing you to track position with reed or electronic switches.
