Airtac PSBR Single Acting Square Head Compact Cylinder PSBR12X75SR
The AirTAC Airtac PSBR Single Acting Square Head Compact Cylinder PSBR12X75SR 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 PSBR12X75SR
The AirTAC PSBR12X75SR is a single-acting push, spring-return pen-size mini cylinder. It provides 42.9 N of net push at 0.5 MPa, utilizing a direct front-cover M5x0.8 mounting thread to bolt straight onto your fixture. An R axial inlet handles plumbing, while a single solenoid line extends the rod.
Fail-safe retracted on air loss, the internal spring pulls the rod home automatically. The SUS316L stainless barrel suits damp environments, and the built-in magnet (-S) supports reed or electronic switches. Because the return spring dictates a 0.2 MPa minimum pressure, the rod only moves when sufficient air is applied.
Airtac PSBR Single Acting Square Head Compact Cylinder PSBR12X75SR Technical Specifications
| Model | Airtac PSBR Single Acting Square Head Compact Cylinder PSBR12X75SR |
|---|---|
| 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 PSBR12X75SR Is Used
Panel Pusher
Extends to push lightweight panels out of a fixture, relying on the spring to retract safely when air is cut.
Part Ejector
Mounts via the front-cover thread to eject small parts off a conveyor line before the return spring resets the rod.
Clamp Release
Uses the single-acting push stroke to open a clamp, ensuring the mechanism defaults to a secure clamped state on air loss.
Is the Airtac PSBR Single Acting Square Head Compact Cylinder PSBR12X75SR the Right Cylinder?
This 12 mm bore at its 75 mm maximum stroke yields 42.9 N net push at 0.5 MPa (65.5 N at 0.7 MPa). Sizing both ways: a 10 mm bore offers 29.8 N, while a 16 mm bore provides 74.8 N at 0.5 MPa. Plan for a safe working load of roughly 26 N (about 60% of the 0.5 MPa figure) to account for seal friction.
For vertical lifts, expect to raise about 2.2 kg with a sane 2:1 safety margin. The Ø5 mm rod handles coaxial thrust well, but over this 75 mm stroke you should add an external guide for off-axis loads. Confirm the M5x0.8 air port and front-mount thread engagement during installation.
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 PSBR12X75SR FAQ
It delivers 42.9 N net push at 0.5 MPa and 65.5 N at 0.7 MPa maximum. Because it is single-acting push with a return spring, there is a 0.2 MPa minimum pressure required before the rod moves, and it fails safely retracted on air loss.
It mounts directly via an M5x0.8 front-cover thread, eliminating separate brackets. The -S suffix indicates a built-in piston magnet compatible with reed or electronic switches, and the SUS316L barrel provides corrosion resistance.
