Airtac PSBR Single Acting Square Head Compact Cylinder PSBR12X75R
The AirTAC Airtac PSBR Single Acting Square Head Compact Cylinder PSBR12X75R 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 PSBR12X75R
The AirTAC PSBR12X75R is a single-acting push pen cylinder with a 75mm stroke and a 12mm bore. 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 42.9N of net push at 0.5 MPa and 65.5N at 0.7 MPa.
The body features a SUS316L stainless barrel and a slim profile for tight jigs. You mount it directly via the front-cover M5x0.8 thread, eliminating extra brackets. A fixed TPU bumper cushions the stroke ends. For this 75mm travel, the thin Ø5mm rod requires an external guide to prevent side-load wear.

|---|---|
| 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 PSBR12X75R Is Used
Panel Pusher
Pushes lightweight panels out of a fixture using 42.9N net force, with the spring ensuring hands stay clear if air pressure drops.
Part Ejector
Ejects small machined parts off a conveyor line; the direct M5x0.8 front mount threads straight into the frame to save space.
Clamp Release
Momentarily pushes a clamp arm open to release a part, relying on the fail-safe retract to secure the clamp during air loss.
Is the Airtac PSBR Single Acting Square Head Compact Cylinder PSBR12X75R the Right Cylinder?
This 12mm bore provides 42.9N net push at 0.5 MPa. Stepping down to a 10mm bore yields 29.8N, while a 16mm bore offers 74.8N. Plan for a safe working load of about 26N, which is roughly 60% of the 0.5 MPa figure. This accounts for seal friction and smooth travel.
The internal spring sets a 0.2 MPa minimum pressure before motion begins. The R axial inlet keeps plumbing in-line. Because the rod is only Ø5mm over a 75mm stroke, add a linear bearing for off-axis loads. The fixed TPU bumper decelerates the last few millimeters; meter-out the exhaust if moving heavy tooling mass.
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 PSBR12X75R FAQ
It provides 42.9N net push at 0.5 MPa and 65.5N at 0.7 MPa. Because an internal spring returns the rod, a minimum pressure of 0.2 MPa is required to overcome the spring and extend the cylinder.
It mounts directly via the front-cover M5x0.8 thread. The R back cover provides an axial air inlet for in-line plumbing. The SUS316L stainless barrel suits damp environments, and this model has no sensor magnet.
