Airtac PSBR Single Acting Square Head Compact Cylinder PSBR8X60U
The AirTAC Airtac PSBR Single Acting Square Head Compact Cylinder PSBR8X60U 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 PSBR8X60U
The AirTAC PSBR8X60U is a single-acting push pen cylinder that extends via one M5x0.8 air port and retracts via an internal spring. It supplies 18.7 N of net push at 0.5 MPa, climbing to 28.7 N at the 0.7 MPa maximum. The fail-safe spring holds the rod retracted on air loss, simplifying wiring to one solenoid line.
You bolt the slim SUS316L stainless body straight to a fixture using the direct M4x0.7 front-cover thread. A fixed TPU bumper cushions the stroke ends. The thin Ø4 mm rod handles coaxial thrust only, so add an external guide for off-axis loads over this 60 mm stroke.

|---|---|
| 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 PSBR8X60U Is Used
Panel Pusher
Uses the 18.7 N push stroke to nudge lightweight electrical panels into a test rack. The fail-safe spring retract pulls the rod clear when air drops.
Part Ejector
Shoves small plastic parts off a belt line. The direct M4x0.7 front mount bolts right to the conveyor frame to save jig space.
Clamp Release
Pushes a holding jaw open against a mechanical spring. The single-acting design needs just one solenoid to control the release cycle.
Is the Airtac PSBR Single Acting Square Head Compact Cylinder PSBR8X60U the Right Cylinder?
This 8 mm bore yields 18.7 N net push at 0.5 MPa. If you need less force, the 6 mm option gives 10.6 N; if your jig requires more, step up to the 10 mm bore for 29.8 N. The internal spring sets a 0.2 MPa minimum pressure before motion begins.
The U suffix provides a 90-degree side air inlet for flat plumbing. The direct M4x0.7 front-cover thread mounts flush to your bracket. Confirm the 60 mm stroke matches your travel before ordering.
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 PSBR8X60U FAQ
It delivers 18.7 N of net push at 0.5 MPa and 28.7 N at the 0.7 MPa maximum. Because an internal spring returns the rod, a 0.2 MPa minimum pressure is required before the piston moves. The spring holds the rod retracted on air loss for fail-safe operation.
It mounts directly via an M4x0.7 thread on the front cover, eliminating separate brackets. The slim body features a SUS316L stainless barrel suited for damp environments. This specific model lacks a sensor magnet and uses a 90-degree side air inlet.
