Airtac PSBR Single Acting Square Head Compact Cylinder PSBR6X40SR
The AirTAC Airtac PSBR Single Acting Square Head Compact Cylinder PSBR6X40SR 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, 40mm stroke; the return spring resets the rod when air is released.

About the Airtac PSBR Single Acting Square Head Compact Cylinder PSBR6X40SR
The AirTAC PSBR6X40SR is a JIS pen-size single-acting push cylinder with a 6 mm bore and 40 mm stroke. Air entering the M5x0.8 port extends the slim Ø3 mm rod, while an internal spring ensures fail-safe retraction upon air loss. It supplies 10.6 N of net push at 0.5 MPa. The SUS316L stainless barrel suits damp or washdown environments, and a fixed TPU bumper cushions the stroke ends.
This model features a built-in piston magnet (-S) for solid-state or reed switch tracking. You bolt it directly to a fixture via the front-cover M3x0.5 thread, eliminating extra brackets. Plan for a safe working load of roughly 6 N (about 60% of the 0.5 MPa rating) to account for friction. The spring sets a 0.3 MPa minimum pressure before motion begins.
Airtac PSBR Single Acting Square Head Compact Cylinder PSBR6X40SR Technical Specifications
| Model | Airtac PSBR Single Acting Square Head Compact Cylinder PSBR6X40SR |
|---|---|
| Series | PSBR JIS pen-size front-mount cylinder |
| Bore size | Ø6 mm |
| Rod diameter | Ø3 mm |
| Stroke | 40 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 PSBR6X40SR Is Used
Panel Pusher
Uses the 10.6 N net push to nudge lightweight electrical panels out of a test nest, with the spring safely pulling the 3 mm rod back when air drops.
Part Eject
Bolts directly via the M3x0.5 front thread to a conveyor side rail to flick small plastic parts off the belt, relying on the fail-safe retract to clear the line.
Clamp Release
Fits into tight machining jigs to push a small holding clamp open; the SUS316L barrel handles coolant splashes while the magnet tracks position.
Is the Airtac PSBR Single Acting Square Head Compact Cylinder PSBR6X40SR the Right Cylinder?
Selecting the PSBR6X40SR means you need compact, single-line actuation. Stepping up to the Ø8 bore yields 18.7 N of net push at 0.5 MPa, while stepping down is unavailable as Ø6 is the smallest option. This Ø6 bore provides 10.6 N at 0.5 MPa and 16.3 N at the 0.7 MPa maximum. With a 2:1 safety margin, it lifts about 0.5 kg vertically.
The direct M3x0.5 front-cover thread mounts straight to your jig, and the R axial back cover inlet keeps plumbing in-line. Because the rod is only 3 mm thick, use an external guide for any off-axis loads. Confirm your solenoid wiring and the fail-safe spring-retract behavior before ordering.
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 PSBR6X40SR FAQ
It provides 10.6 N of net push at 0.5 MPa and 16.3 N at the 0.7 MPa maximum. The internal return spring requires a minimum of 0.3 MPa before the rod begins to move, and the cylinder fails safely retracted on air loss.
It mounts directly via the front-cover M3x0.5 thread, saving space without extra brackets. The -S suffix indicates a built-in piston magnet compatible with AirTAC reed or electronic switches. The SUS316L stainless barrel provides corrosion resistance.
