Airtac PSBR Single Acting Square Head Compact Cylinder PSBR6X15SR
The AirTAC Airtac PSBR Single Acting Square Head Compact Cylinder PSBR6X15SR 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, 15mm stroke; the return spring resets the rod when air is released.

About the Airtac PSBR Single Acting Square Head Compact Cylinder PSBR6X15SR
The AirTAC PSBR6X15SR is a single-acting push pen cylinder that extends via one M5x0.8 air port and retracts via an internal spring, ensuring a fail-safe home position if air pressure drops. It supplies 10.6 N of net push at 0.5 MPa and 16.3 N at 0.7 MPa. The return spring dictates a 0.3 MPa minimum operating pressure before motion begins.
You mount this slim SUS316L stainless body straight to a fixture using the direct M3x0.5 front-cover thread, saving space in compact jigs. A fixed TPU bumper cushions the stroke ends, while the built-in magnet (-S) supports reed or electronic switches for position sensing.
Airtac PSBR Single Acting Square Head Compact Cylinder PSBR6X15SR Technical Specifications
| Model | Airtac PSBR Single Acting Square Head Compact Cylinder PSBR6X15SR |
|---|---|
| Series | PSBR JIS pen-size front-mount cylinder |
| Bore size | Ø6 mm |
| Rod diameter | Ø3 mm |
| Stroke | 15 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 PSBR6X15SR Is Used
Panel Pusher
Uses the 10.6 N push stroke to nudge lightweight electronic panels into a test socket, with the spring safely retracting the 3 mm rod when air is removed.
Part Ejector
Ejects small machined components from a tight jig via the direct M3x0.5 front mount, saving space where a bulkier bracket cannot fit.
Clamp Release
Overcomes a light spring clamp to release a delicate workpiece, relying on the SUS316L barrel for damp or washdown environments.
Is the Airtac PSBR Single Acting Square Head Compact Cylinder PSBR6X15SR the Right Cylinder?
For this 6 mm bore, the 10.6 N net push at 0.5 MPa yields a safe working load of roughly 6 N (about 60% of rated force) to account for seal friction. In vertical lift tasks with a 2:1 safety margin, expect to lift about 0.5 kg. If your application needs less force, note that this is the smallest available bore; stepping up to the 8 mm bore raises the 0.5 MPa push to 18.7 N.
The 3 mm rod provides coaxial thrust but is slender, so add an external guide for off-axis loads over the 15 mm stroke. Confirm your plumbing uses the R axial inlet and that your fixture matches the M3x0.5 front thread.
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 PSBR6X15SR FAQ
It delivers 10.6 N of net push at 0.5 MPa and 16.3 N at 0.7 MPa. Because it is single-acting push with a return spring, it requires a minimum operating pressure of 0.3 MPa to extend the rod.
It mounts directly via an M3x0.5 thread on the front cover, eliminating separate brackets. The built-in magnet (-S) works with AirTAC reed or electronic switches for position detection.
