Airtac PSBR Single Acting Square Head Compact Cylinder PSBR10X50U
The AirTAC Airtac PSBR Single Acting Square Head Compact Cylinder PSBR10X50U 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, 50mm stroke; the return spring resets the rod when air is released.

About the Airtac PSBR Single Acting Square Head Compact Cylinder PSBR10X50U
The AirTAC PSBR10X50U is a JIS pen-size single-acting push cylinder with a 50 mm stroke. Air entering the M5x0.8 port extends the rod, while an internal spring retracts it. This fail-safe design ensures the rod pulls back on air loss. It delivers 29.8 N of net push at 0.5 MPa, with the return spring force already deducted.
You mount it directly via the front-cover M4x0.7 thread, saving space in tight jigs. The SUS316L stainless barrel provides corrosion resistance. 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 | 50 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 PSBR10X50U Is Used
Panel Pusher
Extends to push a lightweight panel into a fixture, with the spring safely retracting the rod when air drops.
Part Ejector
Uses the direct front mount to bolt over a belt and eject small parts using the 29.8 N push force.
Clamp Release
Applies thrust to release a small spring clamp, relying on the fail-safe retract to reset the tool.
Is the Airtac PSBR Single Acting Square Head Compact Cylinder PSBR10X50U the Right Cylinder?
This 10 mm bore provides 29.8 N net push at 0.5 MPa and 45.5 N at 0.7 MPa. If you need less force, the 8 mm bore yields 18.7 N at 0.5 MPa. For heavier tasks, the 12 mm bore offers 42.9 N. The internal spring sets a 0.2 MPa minimum pressure before motion begins.
The U suffix adds a 90-degree side inlet for flat plumbing. The direct front-cover M4x0.7 thread bolts straight to your fixture. The 50 mm stroke is well within the 60 mm limit for this bore. Over this length, the 4 mm rod needs an external guide to prevent side load damage.
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 PSBR10X50U FAQ
It provides 29.8 N net push at 0.5 MPa and 45.5 N at 0.7 MPa. The return spring requires a minimum 0.2 MPa air pressure to extend the rod.
It mounts directly via the front-cover M4x0.7 thread. The U suffix indicates a 90-degree side air inlet on the back cover, while the main air port remains M5x0.8.
