Airtac PSBR Single Acting Square Head Compact Cylinder PSBR6X50R
The AirTAC Airtac PSBR Single Acting Square Head Compact Cylinder PSBR6X50R 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, 50mm stroke; the return spring resets the rod when air is released.

About the Airtac PSBR Single Acting Square Head Compact Cylinder PSBR6X50R
The AirTAC PSBR6X50R is a JIS pen-size single-acting push cylinder with a 50 mm stroke. Air entering the M5x0.8 port extends the rod, while an internal spring retracts it. This fail-safe design ensures the rod pulls home on air loss, needing only one solenoid line. It delivers 10.6 N of net push at 0.5 MPa.
A DIRECT front-cover M3x0.5 thread allows straight bolt-on mounting to your fixture, saving space. The SUS316L stainless barrel suits damp environments, and a fixed TPU bumper cushions the stroke ends. Plan for a safe working load of about 6 N (roughly 60% of the 0.5 MPa rating) to account for seal friction and smooth travel.
Airtac PSBR Single Acting Square Head Compact Cylinder PSBR6X50R Technical Specifications
| Model | Airtac PSBR Single Acting Square Head Compact Cylinder PSBR6X50R |
|---|---|
| Series | PSBR JIS pen-size front-mount cylinder |
| Bore size | Ø6 mm |
| Rod diameter | Ø3 mm |
| Stroke | 50 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 PSBR6X50R Is Used
Small Part Ejection
Pushes lightweight plastic parts out of a machining nest. The fail-safe retract ensures the ejector clears the workspace if compressed air drops.
Panel Pusher
Acts as a compact pusher for thin electronic panels. The direct M3x0.5 front mount threads directly into tight assembly jigs without brackets.
Clamp Release
Releases a lightweight holding clamp via spring return. The single solenoid line simplifies wiring while providing a safe retracted state.
Is the Airtac PSBR Single Acting Square Head Compact Cylinder PSBR6X50R 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, stepping down is not an option as this is the smallest diameter. If you need more power, moving up to the 8 mm bore yields 18.7 N at 0.5 MPa. The internal spring sets a 0.3 MPa minimum pressure before motion begins.
The DIRECT front-cover M3x0.5 thread mounts straight to the jig without extra brackets. The R axial back cover provides in-line plumbing. The thin Ø3 mm piston rod handles coaxial thrust well, but over this 50 mm stroke you should add an external guide for any off-axis loads.
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 PSBR6X50R FAQ
It provides 10.6 N net push at 0.5 MPa and 16.3 N at 0.7 MPa. The internal return spring requires a 0.3 MPa minimum pressure before the rod extends. It is single-acting push, so the spring holds the rod retracted on air loss.
It mounts directly via a front-cover M3x0.5 thread, separate from the M5x0.8 air port. The barrel is SUS316L stainless steel for damp environments. This specific model has no magnet for position sensing.
