Airtac PSBR Single Acting Square Head Compact Cylinder PSBR10X30U
The AirTAC Airtac PSBR Single Acting Square Head Compact Cylinder PSBR10X30U 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, 30mm stroke; the return spring resets the rod when air is released.

About the Airtac PSBR Single Acting Square Head Compact Cylinder PSBR10X30U
The AirTAC PSBR10X30U is a JIS pen-size single-acting push cylinder with a 10 mm bore and 30 mm 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. It supplies 29.8 N of net push at 0.5 MPa and 45.5 N at 0.7 MPa.
A direct M4x0.7 front-cover mounting thread bolts straight to your fixture, saving space in tight assemblies. The SUS316L stainless barrel suits damp environments, and a fixed TPU bumper cushions the stroke ends. Plan for a safe working load of about 18 N (roughly 60 percent of the 0.5 MPa rating) to account for seal friction.
Airtac PSBR Single Acting Square Head Compact Cylinder PSBR10X30U Technical Specifications
| Model | Airtac PSBR Single Acting Square Head Compact Cylinder PSBR10X30U |
|---|---|
| Series | PSBR JIS pen-size front-mount cylinder |
| Bore size | Ø10 mm |
| Rod diameter | Ø4 mm |
| Stroke | 30 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 PSBR10X30U Is Used
Panel Pusher
Uses the M4x0.7 front-mount thread to bolt directly onto a jig, pushing light panels into a locating slot with 29.8 N of net force.
Part Ejector
Extends 30 mm to knock small parts off a conveyor line, relying on the internal spring to retract safely if compressed air drops.
Clamp Release
Fits into a narrow pen-size pocket to hold a workpiece via spring return, releasing the clamp only when 0.5 MPa air pressure is applied.
Is the Airtac PSBR Single Acting Square Head Compact Cylinder PSBR10X30U the Right Cylinder?
When sizing this 10 mm bore unit against its neighbors, the smaller Ø8 bore yields 18.7 N net push at 0.5 MPa, while the larger Ø12 bore provides 42.9 N at the same pressure. Choose this model if 29.8 N at 0.5 MPa fits your requirement. The spring sets a 0.2 MPa minimum pressure before motion begins. Confirm your ordering code includes the U designation for the 90-degree side air inlet and the direct M4x0.7 front-mount thread.
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 PSBR10X30U FAQ
The net push force is 29.8 N at 0.5 MPa and 45.5 N at 0.7 MPa. Because it is spring-return, a minimum pressure of 0.2 MPa is required before the rod begins to move, and the rod fails safe to the retracted position on air loss.
It mounts directly via an M4x0.7 thread on the front cover, eliminating separate brackets. The barrel is constructed from SUS316L stainless steel for durability in damp environments. This specific model does not include a sensor magnet.
