Airtac PSBR Single Acting Square Head Compact Cylinder PSBR6X30SR
The AirTAC Airtac PSBR Single Acting Square Head Compact Cylinder PSBR6X30SR is a single acting, push type (spring return) pen-size mini cylinder with direct front-cover mounting (M3×0.5 thread). A single air port drives the push stroke on a Ø6mm bore, 30mm stroke; the return spring resets the rod when air is released.

About the Airtac PSBR Single Acting Square Head Compact Cylinder PSBR6X30SR
The AirTAC PSBR6X30SR is a JIS pen-size single-acting push cylinder with a 6mm bore and 30mm 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 about 10.6 N of net push at 0.5 MPa.
You bolt this slim mini body straight to a fixture via the direct M3x0.5 front-cover thread, saving space. The SUS316L stainless barrel suits damp environments. A fixed TPU bumper cushions the stroke ends. The built-in magnet (-S) works with reed or electronic switches for position sensing.
Airtac PSBR Single Acting Square Head Compact Cylinder PSBR6X30SR Technical Specifications
| Model | Airtac PSBR Single Acting Square Head Compact Cylinder PSBR6X30SR |
|---|---|
| Series | PSBR JIS pen-size front-mount cylinder |
| Bore size | Ø6 mm |
| Rod diameter | Ø3 mm |
| Stroke | 30 mm |
| Acting type | Single acting, push type (spring return) |
| Front-mount thread | M3×0.5 |
| Port size | M5×0.8 |
|---|---|
| Operating pressure | 0.3 – 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 (M3×0.5); barrel is SUS316L. Forces below are NET spring-deducted values. Confirm against the product label.
Net Push Force (Ø6mm)
| Pressure | Net push force |
|---|---|
| 0.5 MPa | 10.6 N |
| 0.7 MPa (max) | 16.3 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 PSBR6X30SR Is Used
Small Part Ejector
Uses the fail-safe retract to push light components off a machining bed, returning home when air pressure drops.
Panel Pusher
Bolts directly via the M3x0.5 front thread to index thin electronic panels in tight assembly jigs without needing brackets.
Clamp Release
Applies 10.6 N of net push at 0.5 MPa to overcome a light spring clamp, releasing delicate parts held during a process.
Is the Airtac PSBR Single Acting Square Head Compact Cylinder PSBR6X30SR the Right Cylinder?
This 6mm bore provides 10.6 N net push at 0.5 MPa and 16.3 N at 0.7 MPa. If you need less force, step down to the 8mm bore variant (wait, 6mm is the smallest, so you must step UP to the 8mm bore for 18.7 N at 0.5 MPa). This accounts for seal friction and smooth travel.
The internal return spring sets a 0.3 MPa minimum pressure before motion begins. The thin Ø3 mm rod handles coaxial thrust well, but over long strokes or off-axis loads, add an external guide or linear bearing to prevent side load damage. Confirm the direct M3x0.5 front mount and R axial inlet suit your jig.
Quick checklist
- ✓ Net push force at your working pressure
- ✓ Bolt directly through the front cover (M3×0.5)
- ✓ 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 0.3 – 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 PSBR6X30SR FAQ
It delivers 10.6 N net push at 0.5 MPa and 16.3 N at 0.7 MPa maximum. The return spring requires a minimum 0.3 MPa air pressure to extend the rod, and the cylinder fails safe retracted on air loss.
It mounts directly via the front-cover M3x0.5 thread, separate from the M5x0.8 air port. The -S suffix indicates a built-in piston magnet compatible with reed or electronic switches for position confirmation.
