Airtac PSBR Single Acting Square Head Compact Cylinder PSBR6X25SR
The AirTAC Airtac PSBR Single Acting Square Head Compact Cylinder PSBR6X25SR 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, 25mm stroke; the return spring resets the rod when air is released.

About the Airtac PSBR Single Acting Square Head Compact Cylinder PSBR6X25SR
The AirTAC PSBR6X25SR is a single-acting push pen cylinder that extends via one M5x0.8 air port and retracts via an internal spring. It delivers 10.6 N of net push at 0.5 MPa, providing fail-safe retraction on air loss. A built-in piston magnet enables position sensing with reed or electronic switches.
This slim mini body features a SUS316L stainless barrel and bolts directly via its front-cover M3x0.5 thread. The fixed TPU bumper decelerates the stroke end. Plan for a safe working load of about 6 N (60% of the 0.5 MPa rating) to account for seal friction.
Airtac PSBR Single Acting Square Head Compact Cylinder PSBR6X25SR Technical Specifications
| Model | Airtac PSBR Single Acting Square Head Compact Cylinder PSBR6X25SR |
|---|---|
| Series | PSBR JIS pen-size front-mount cylinder |
| Bore size | Ø6 mm |
| Rod diameter | Ø3 mm |
| Stroke | 25 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 PSBR6X25SR Is Used
Panel Pusher
Uses the 10.6 N push stroke to index thin panels forward in a compact assembly jig.
Part Ejector
Spring-return fail-safe action keeps the rod clear on air loss, preventing jams at the test station exit.
Clamp Release
Direct M3x0.5 front-mount thread secures the body tightly to release small electronic components.
Is the Airtac PSBR Single Acting Square Head Compact Cylinder PSBR6X25SR the Right Cylinder?
This 6 mm bore provides 10.6 N net push at 0.5 MPa and 16.3 N at 0.7 MPa. If your task needs less force, note there is no smaller bore in this series, so verify your minimum pressure requirement. If you need more power, stepping up to the 8 mm bore yields 18.7 N at 0.5 MPa. The direct front mount and spring-return fail-safe design simplify jig integration.
Confirm the 25 mm stroke fits your cycle. The R axial inlet handles in-line plumbing, while the thin Ø3 mm rod requires an external guide for off-axis loads. Above mid-speed with tooling mass, meter-out the exhaust because the fixed TPU bumper only absorbs the final few millimeters.
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 PSBR6X25SR FAQ
It provides 10.6 N net push at 0.5 MPa and 16.3 N at 0.7 MPa. The internal return spring sets a 0.3 MPa minimum pressure before the rod moves, and the cylinder fails safely retracted on air loss.
It bolts directly via a front-cover M3x0.5 thread into your fixture. The -S suffix indicates a built-in piston magnet compatible with reed or electronic switches, and the SUS316L barrel suits damp environments.
