Airtac PSBR Single Acting Square Head Compact Cylinder PSBR6X5R
The AirTAC Airtac PSBR Single Acting Square Head Compact Cylinder PSBR6X5R 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, 5mm stroke; the return spring resets the rod when air is released.

About the Airtac PSBR Single Acting Square Head Compact Cylinder PSBR6X5R
The AirTAC PSBR6X5R is a single-acting push-type pen cylinder that extends via air pressure and retracts via an internal spring. It provides 10.6 N of net push at 0.5 MPa, making it ideal for tiny ejection tasks. The fail-safe spring design ensures the rod pulls home on air loss.
This slim mini body features a SUS316L stainless barrel and bolts directly to a fixture via its M3x0.5 front-cover thread. Air enters through a separate M5x0.8 port, while a fixed TPU bumper cushions the stroke ends. Plan for a safe working load of roughly 6 N, which accounts for seal friction and smooth travel.

|---|---|
| Series | PSBR JIS pen-size front-mount cylinder |
| Bore size | Ø6 mm |
| Rod diameter | Ø3 mm |
| Stroke | 5 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 PSBR6X5R Is Used
Micro Part Ejection
Uses the short 5mm stroke to push small electronic components out of tight machining jigs with a reliable spring return.
Panel Pusher
Direct front-mounting secures the cylinder directly to a sub-plate to nudge lightweight panels into a sensing zone.
Clamp Release
Applies 10.6 N of thrust to overcome a light spring clamp, automatically retracting when air pressure drops.
Is the Airtac PSBR Single Acting Square Head Compact Cylinder PSBR6X5R the Right Cylinder?
For this 6mm bore, the 10.6 N net push at 0.5 MPa is the smallest available in the series. If your task requires slightly more force, stepping up to the 8mm bore yields 18.7 N of usable thrust. The Ø3 mm rod is built for coaxial thrust, so over its 5mm stroke you must avoid side loads and use an external guide for off-axis tooling.
Confirm the R axial inlet orientation fits your in-line plumbing. The direct front-cover mount saves space, but verify your M3x0.5 bolt engagement. Remember the internal spring sets a 0.3 MPa minimum pressure before motion begins.
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 PSBR6X5R FAQ
The PSBR6X5R provides 10.6 N of net push at 0.5 MPa and 16.3 N at 0.7 MPa. Because an internal spring returns the rod, a minimum pressure of 0.3 MPa is required before the cylinder can move.
It mounts directly via the M3x0.5 front-cover thread, eliminating separate brackets. The SUS316L stainless barrel resists damp environments, and air is supplied through an R axial inlet ported at M5x0.8.
