Airtac PSBR Single Acting Square Head Compact Cylinder PSBR10X40SU
The AirTAC Airtac PSBR Single Acting Square Head Compact Cylinder PSBR10X40SU 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, 40mm stroke; the return spring resets the rod when air is released.

About the Airtac PSBR Single Acting Square Head Compact Cylinder PSBR10X40SU
The AirTAC PSBR10X40SU is a JIS pen-size single-acting push cylinder with a 40 mm stroke. Air entering the M5x0.8 port extends the rod, while an internal spring retracts it. You get 29.8 N of net push at 0.5 MPa, rising to 45.5 N at the 0.7 MPa maximum. The fail-safe design holds the rod retracted on air loss.
A direct M4x0.7 front-cover mounting thread bolts straight to your fixture, saving space. The SUS316L stainless barrel suits damp environments, and a fixed TPU bumper cushions the stroke ends. The built-in magnet (-S) works with reed or electronic switches, while the U back cover provides a 90-degree side air inlet.

|---|---|
| Series | PSBR JIS pen-size front-mount cylinder |
| Bore size | Ø10 mm |
| Rod diameter | Ø4 mm |
| Stroke | 40 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 PSBR10X40SU Is Used
Panel Pusher
Extends to push a lightweight panel into a fixture, with the internal spring retracting the rod safely when air drops.
Part Ejector
Uses the direct M4x0.7 front mount to bolt straight over a belt, ejecting small parts using 29.8 N of push force.
Clamp Release
Overcomes a spring clamp to release a part, relying on the SUS316L barrel for washdown environments.
Is the Airtac PSBR Single Acting Square Head Compact Cylinder PSBR10X40SU the Right Cylinder?
This 10 mm bore provides 29.8 N net push at 0.5 MPa. Stepping down, the 8 mm bore yields 18.7 N; stepping up, the 12 mm bore yields 42.9 N. The direct M4x0.7 front mount and fail-safe spring retract suit compact assemblies. The thin 4 mm rod requires an external guide for off-axis loads over this 40 mm stroke.
Confirm the M5x0.8 air port and the 90-degree side inlet fit your plumbing. The fixed TPU bumper handles light loads, but meter-out the exhaust if moving real mass at higher speeds.
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 PSBR10X40SU FAQ
The net push force is 29.8 N at 0.5 MPa and 45.5 N at 0.7 MPa. The internal return spring sets a 0.2 MPa minimum pressure before the rod moves, and the cylinder fails safe to the retracted position on air loss.
It mounts directly via an M4x0.7 thread on the front cover, eliminating extra brackets. The -S suffix indicates a built-in piston magnet compatible with reed or electronic switches, and the U cover provides a 90-degree side inlet.
