Airtac PSBR Single Acting Square Head Compact Cylinder PSBR8X60SR
The AirTAC Airtac PSBR Single Acting Square Head Compact Cylinder PSBR8X60SR 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 PSBR8X60SR
The AirTAC PSBR8X60SR is a single-acting push-type pen cylinder featuring a 60mm stroke and a built-in piston magnet. Air entering the M5x0.8 port extends the rod, while an internal spring retracts it upon air release. This fail-safe design ensures the rod returns home if pneumatic pressure drops, requiring only one solenoid line for operation. It supplies 18.7 N of net push at 0.5 MPa.
The direct front-cover M4x0.7 mounting thread allows straight integration into tight fixtures without extra brackets. A slim SUS316L stainless barrel resists corrosion in damp environments. The fixed TPU bumper decelerates the rod at stroke ends, but with heavy tooling mass at mid-to-high speeds, you should meter-out the exhaust or add an external shock absorber.
Airtac PSBR Single Acting Square Head Compact Cylinder PSBR8X60SR Technical Specifications
| Model | Airtac PSBR Single Acting Square Head Compact Cylinder PSBR8X60SR |
|---|---|
| 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 PSBR8X60SR Is Used
Panel Pusher
Uses the direct front-cover thread to bolt straight onto a jig, pushing light panels forward before a spring safely retracts the rod on air loss.
Part Ejector
Ejects small machined components from a conveyor line with 18.7 N of net push, relying on the axial R inlet to keep pneumatic plumbing compact.
Clamp Release
Momentarily pushes a holding clamp open to release a finished part, with the internal spring ensuring the clamp resets if the air supply fails.
Is the Airtac PSBR Single Acting Square Head Compact Cylinder PSBR8X60SR the Right Cylinder?
This 8mm bore provides 18.7 N net push at 0.5 MPa and 28.7 N at the 0.7 MPa maximum. If your task needs less force, the 6mm bore yields 10.6 N at 0.5 MPa. If you need more power, stepping up to the 10mm bore gives 29.8 N at 0.5 MPa. The R axial inlet keeps plumbing in-line, and the direct front mount saves space.
The single-acting spring holds the rod retracted on air loss. The Ø4mm rod handles coaxial thrust well, but over this 60mm stroke or under off-axis loads, add an external guide or linear bearing to prevent side load. Confirm your M4x0.7 front-mount thread engagement 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 PSBR8X60SR FAQ
The net usable push force is 18.7 N at 0.5 MPa and 28.7 N at the 0.7 MPa maximum. The internal return spring sets a 0.2 MPa minimum pressure before the rod moves, and the cylinder fails safe to the retracted position on air loss.
The -S suffix indicates a built-in piston magnet compatible with AirTAC reed or electronic switches for position sensing. It mounts directly via the front-cover M4x0.7 thread, while the R back cover provides an axial air inlet for in-line plumbing.
