Airtac PSBR Single Acting Square Head Compact Cylinder PSBR12X75SU
The AirTAC Airtac PSBR Single Acting Square Head Compact Cylinder PSBR12X75SU 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 PSBR12X75SU
The AirTAC PSBR12X75SU is a single-acting push pen cylinder with a 75mm stroke. Air entering the M5x0.8 port extends the rod, while an internal spring retracts it on air loss for fail-safe retraction. It provides 42.9N of net push at 0.5MPa and 65.5N at 0.7MPa.
This 12mm bore model bolts directly to a fixture via its front-cover M5x0.8 thread, saving space in tight jigs. The SUS316L stainless barrel suits damp environments, and the U back cover provides a 90-degree side inlet. A fixed TPU bumper decelerates the rod at stroke ends. Plan for a safe working load of about 26N, which is roughly 60 percent of the 0.5MPa rating.

|---|---|
| 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 PSBR12X75SU Is Used
Panel Pusher
Extends 75mm to push a lightweight panel out of a fixture, relying on the spring to retract the rod safely when air drops.
Part Ejector
Uses 42.9N of net push at 0.5MPa to kick small parts off a line, with the front M5x0.8 thread bolting directly to the frame.
Clamp Release
Overcomes a light clamping force to release a part, using the 90-degree side inlet to keep plumbing flat against the machine.
Is the Airtac PSBR Single Acting Square Head Compact Cylinder PSBR12X75SU the Right Cylinder?
This 12mm bore provides 42.9N net push at 0.5MPa. Stepping down to a 10mm bore yields 29.8N, while moving up to a 16mm bore offers 74.8N. Choose this model when your fixture needs moderate push force and fail-safe spring retraction.
The direct front-cover M5x0.8 thread mounts straight to your tool, and the U option routes air from the side. The internal spring requires a minimum 0.2MPa to move. Confirm the 75mm stroke matches your travel, and note the built-in magnet works with reed or electronic switches.
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 PSBR12X75SU FAQ
It delivers 42.9N of net push at 0.5MPa and 65.5N at 0.7MPa. Because a return spring is built in, a minimum pressure of 0.2MPa is required before the rod moves, and the cylinder fails safe to the retracted position on air loss.
It mounts directly via the front-cover M5x0.8 thread. The built-in magnet works with reed or electronic switches. The SUS316L stainless barrel resists moisture, and the U back cover provides a 90-degree side air inlet.
