Airtac PSBR Single Acting Square Head Compact Cylinder PSBR6X20R
The AirTAC Airtac PSBR Single Acting Square Head Compact Cylinder PSBR6X20R 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, 20mm stroke; the return spring resets the rod when air is released.

About the Airtac PSBR Single Acting Square Head Compact Cylinder PSBR6X20R
The AirTAC PSBR6X20R is a single-acting push-type pen cylinder featuring a direct M3x0.5 front-cover mounting thread. Air entering the M5x0.8 port extends the rod, while an internal spring retracts it on air loss for fail-safe retraction. It supplies about 10.6 N of net push at 0.5 MPa.
Built with a SUS316L stainless barrel and a slim 6 mm body, it saves space in tight jigs. The fixed TPU bumper decelerates the rod near stroke ends. For smooth operation, plan for a safe working load of roughly 6 N, which is about 60 percent of the rated force.
Airtac PSBR Single Acting Square Head Compact Cylinder PSBR6X20R Technical Specifications
| Model | Airtac PSBR Single Acting Square Head Compact Cylinder PSBR6X20R |
|---|---|
| Series | PSBR JIS pen-size front-mount cylinder |
| Bore size | Ø6 mm |
| Rod diameter | Ø3 mm |
| Stroke | 20 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 PSBR6X20R Is Used
Micro Part Ejector
Uses the spring-return push to eject small molded components from a die, ensuring the rod safely retracts if air pressure drops.
Panel Pusher
Extends to nudge lightweight electronic panels into a test socket, relying on the 6.4 N safe working load for gentle contact.
Lab Valve Trigger
Cycles a delicate sampling valve in a compact analytical rig where the SUS316L barrel handles damp environments.
Is the Airtac PSBR Single Acting Square Head Compact Cylinder PSBR6X20R 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, review the PSBR series limits, but if you need more power, step up to the 8 mm bore yielding 18.7 N at 0.5 MPa. The internal spring requires a minimum 0.3 MPa pressure before motion begins.
The direct M3x0.5 front-mount thread bolts straight to your fixture, and the R axial inlet handles in-line plumbing. It lacks a sensor magnet. Ensure your load stays coaxial, as the 3 mm rod is for thrust, not side load.
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 PSBR6X20R FAQ
It delivers 10.6 N net push at 0.5 MPa and 16.3 N at 0.7 MPa. Because it is spring-return, a minimum 0.3 MPa is required to overcome the spring and move the rod.
It mounts directly via the front-cover M3x0.5 thread. The R back cover provides an axial air inlet for in-line plumbing, separate from the front mount.
