Airtac PSBR Single Acting Square Head Compact Cylinder PSBR8X60SU
The AirTAC Airtac PSBR Single Acting Square Head Compact Cylinder PSBR8X60SU 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 PSBR8X60SU
The AirTAC PSBR8X60SU is a single-acting push, spring-return pen-size mini cylinder. Air entering the M5x0.8 port extends the rod, while an internal spring retracts it on air loss for fail-safe retraction. It supplies 18.7 N of net push at 0.5 MPa and 28.7 N at 0.7 MPa.
This 60mm stroke model mounts directly via its front-cover M4x0.7 thread, saving space in tight jigs. The SUS316L stainless barrel resists corrosion in damp environments. A fixed TPU bumper decelerates the rod at stroke ends, and the built-in magnet (-S) supports reed or electronic switches. The U suffix provides a 90-degree side inlet for flat plumbing.

|---|---|
| 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 PSBR8X60SU Is Used
Panel Pusher
Extends to push lightweight panels or cards into a slot, with the spring safely retracting the rod if compressed air drops.
Part Ejector
Uses the direct front-mount thread to bolt over a conveyor, ejecting small parts using the 90-degree side inlet for flat plumbing.
Clamp Release
Applies 18.7 N of push force at 0.5 MPa to release a small holding clamp, returning home automatically via the internal spring.
Is the Airtac PSBR Single Acting Square Head Compact Cylinder PSBR8X60SU the Right Cylinder?
At the maximum 60mm stroke limit for this bore, the PSBR8X60SU provides 18.7 N net push at 0.5 MPa. If you need less force, the Ø6 bore offers 10.6 N at 0.5 MPa; for more power, step up to the Ø10 bore which yields 29.8 N.
The direct M4x0.7 front-cover thread bolts straight to your fixture without extra brackets. Remember the spring sets a 0.2 MPa minimum pressure before motion begins. Because the rod is only Ø4 mm, add an external guide or linear bearing over this long 60mm stroke to prevent side-load damage.
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 PSBR8X60SU FAQ
The net push force is 18.7 N at 0.5 MPa and 28.7 N at 0.7 MPa (maximum pressure). Because it is spring-return, a minimum pressure of 0.2 MPa is required before the rod moves, and the spring holds the rod retracted on air loss.
It mounts directly via the front-cover M4x0.7 thread. The built-in magnet (-S) works with AirTAC reed or electronic switches. The SUS316L stainless barrel provides excellent corrosion resistance for damp environments.
