Airtac PSBR Single Acting Square Head Compact Cylinder PSBR8X60R
The AirTAC Airtac PSBR Single Acting Square Head Compact Cylinder PSBR8X60R is a single acting, push type (spring return) pen-size mini cylinder with direct front-cover mounting (M4×0.7 thread). A single air port drives the push stroke on a Ø8mm bore, 60mm stroke; the return spring resets the rod when air is released.

About the Airtac PSBR Single Acting Square Head Compact Cylinder PSBR8X60R
The AirTAC PSBR8X60R is a single-acting push pen cylinder with a 60mm stroke. Air entering the M5x0.8 port extends the rod, while an internal spring retracts it. This fail-safe design ensures the rod returns home on air loss. It delivers 18.7N of net push at 0.5 MPa.
The direct M4x0.7 front-cover thread bolts straight to your fixture, saving space in tight jigs. The SUS316L stainless barrel resists corrosion in damp environments. A fixed TPU bumper decelerates the rod at stroke ends. For this 8mm bore, plan for a safe working load of about 11N, which lifts roughly 1kg vertically with a 2:1 margin.
Airtac PSBR Single Acting Square Head Compact Cylinder PSBR8X60R Technical Specifications
| Model | Airtac PSBR Single Acting Square Head Compact Cylinder PSBR8X60R |
|---|---|
| Series | PSBR JIS pen-size front-mount cylinder |
| Bore size | Ø8 mm |
| Rod diameter | Ø4 mm |
| Stroke | 60 mm |
| Acting type | Single acting, push type (spring return) |
| Front-mount thread | M4×0.7 |
| Port size | M5×0.8 |
|---|---|
| Operating pressure | 0.2 – 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 (M4×0.7); barrel is SUS316L. Forces below are NET spring-deducted values. Confirm against the product label.
Net Push Force (Ø8mm)
| Pressure | Net push force |
|---|---|
| 0.5 MPa | 18.7 N |
| 0.7 MPa (max) | 28.7 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 PSBR8X60R Is Used
Panel Pusher
Extends to push a lightweight panel into a clip. The fail-safe retract ensures the arm clears the workspace if air pressure drops.
Part Ejector
Uses the 60mm stroke to knock small parts off a line. The direct M4x0.7 front mount bolts right to the conveyor frame.
Clamp Release
Pushes a small latch to free a clamped part. The SUS316L barrel handles splash coolant in machining areas.
Is the Airtac PSBR Single Acting Square Head Compact Cylinder PSBR8X60R the Right Cylinder?
This 8mm bore provides 18.7N net push at 0.5 MPa and 28.7N at 0.7 MPa. If you need less force, the 6mm bore offers 10.6N at 0.5 MPa. For heavier tasks, the 10mm bore yields 29.8N. The internal spring sets a 0.2 MPa minimum pressure before motion begins.
The 4mm rod is built for coaxial thrust. Over this 60mm stroke, add an external guide to prevent side loading. The R back cover provides an axial air inlet for in-line plumbing. Confirm the M4x0.7 front-mount thread matches your fixture.
Quick checklist
- ✓ Net push force at your working pressure
- ✓ Bolt directly through the front cover (M4×0.7)
- ✓ 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 0.2 – 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 PSBR8X60R FAQ
The net push force is 18.7N at 0.5 MPa and 28.7N at 0.7 MPa. Because it is spring-return, a minimum pressure of 0.2 MPa is required to overcome the spring and move the rod.
It mounts directly via the M4x0.7 thread on the front cover. The R back cover provides an axial air inlet for in-line plumbing, separate from the M5x0.8 port.
