Airtac PSBR Single Acting Square Head Compact Cylinder PSBR12X75U
The AirTAC Airtac PSBR Single Acting Square Head Compact Cylinder PSBR12X75U is a single acting, push type (spring return) pen-size mini cylinder with direct front-cover mounting (M5×0.8 thread). A single air port drives the push stroke on a Ø12mm bore, 75mm stroke; the return spring resets the rod when air is released.

About the Airtac PSBR Single Acting Square Head Compact Cylinder PSBR12X75U
The AirTAC PSBR12X75U is a single-acting push pen cylinder with a 75mm stroke and 12mm bore. It provides 42.9N net push at 0.5 MPa and 65.5N at 0.7 MPa. A built-in spring retracts the rod when air stops, ensuring a fail-safe home position on air loss.
You bolt it directly via the front-cover M5x0.8 thread, saving space in tight jigs. The SUS316L stainless barrel resists corrosion in damp environments. Air enters the M5x0.8 port to extend the rod, while a fixed TPU bumper cushions the stroke ends.

|---|---|
| Series | PSBR JIS pen-size front-mount cylinder |
| Bore size | Ø12 mm |
| Rod diameter | Ø5 mm |
| Stroke | 75 mm |
| Acting type | Single acting, push type (spring return) |
| Front-mount thread | M5×0.8 |
| 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 75 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 (M5×0.8); barrel is SUS316L. Forces below are NET spring-deducted values. Confirm against the product label.
Net Push Force (Ø12mm)
| Pressure | Net push force |
|---|---|
| 0.5 MPa | 42.9 N |
| 0.7 MPa (max) | 65.5 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 PSBR12X75U Is Used
Part Ejection
Uses the 42.9N push to eject small machined components from a fixture, with the spring ensuring safe retraction.
Panel Pusher
Front-mounts directly via the M5x0.8 thread to push lightweight panels into a test slot, saving jig space.
Clamp Release
Extends 75mm to release a conveyor clamp on air supply, defaulting to a secure closed state during air loss.
Is the Airtac PSBR Single Acting Square Head Compact Cylinder PSBR12X75U the Right Cylinder?
This 12mm bore yields 42.9N net push at 0.5 MPa. Stepping down to a 10mm bore gives 29.8N, while a 16mm bore offers 74.8N. Match your load to these figures. The internal return spring sets a 0.2 MPa minimum pressure before motion begins.
The direct M5x0.8 front-cover thread mounts flush to your fixture. This PSBR12X75U variant features a U code for a 90-degree side air inlet. It has no magnet; add an S suffix if you need electronic or reed switch sensing.
Quick checklist
- ✓ Net push force at your working pressure
- ✓ Bolt directly through the front cover (M5×0.8)
- ✓ Only one air line / solenoid needed
- ✓ Fail-safe retract on air loss
- ✓ Magnet (S) for sensors?
- ✓ Stroke ≤ 75 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 PSBR12X75U FAQ
The net push force is 42.9N at 0.5 MPa and 65.5N at 0.7 MPa. Because it is spring-return, a minimum pressure of 0.2 MPa is required to overcome the spring and extend the rod.
It mounts directly via an M5x0.8 front-cover thread. The barrel is SUS316L stainless steel for damp environments, and a fixed TPU bumper cushions the ends. This U variant has a 90-degree side inlet.
