Airtac PSBR Single Acting Square Head Compact Cylinder PSBR12X30U
The AirTAC Airtac PSBR Single Acting Square Head Compact Cylinder PSBR12X30U 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, 30mm stroke; the return spring resets the rod when air is released.

About the Airtac PSBR Single Acting Square Head Compact Cylinder PSBR12X30U
The AirTAC PSBR12X30U is a JIS pen-size single-acting push cylinder that extends via one M5x0.8 air port and retracts automatically via an internal spring. It supplies 42.9 N of net push at 0.5 MPa, climbing to 65.5 N at the 0.7 MPa maximum. A 90-degree side inlet keeps pneumatic plumbing flat against your fixture.
You bolt this actuator straight to a tool using the direct M5x0.8 front-cover mounting thread, eliminating separate brackets. The SUS316L stainless barrel shrinks the envelope for tight jigs, while a fixed TPU bumper cushions the stroke ends. Plan for roughly 26 N of actual work output, as the thin Ø5 mm rod is built strictly for coaxial thrust rather than side loading.
Airtac PSBR Single Acting Square Head Compact Cylinder PSBR12X30U Technical Specifications

|---|---|
| Series | PSBR JIS pen-size front-mount cylinder |
| Bore size | Ø12 mm |
| Rod diameter | Ø5 mm |
| Stroke | 30 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 PSBR12X30U Is Used
Panel Pusher
Drives lightweight electronic panels forward out of a test nest using 42.9 N net push, with the spring returning the rod safely when air drops.
Part Ejector
Pushes machined pins off a conveyor line; the direct M5x0.8 front mount threads right into the machine frame to save build space.
Clamp Release
Overcomes a holding mechanism to unclamp parts, relying on the fixed TPU bumper to soften the impact at the end of the 30 mm travel.
Is the Airtac PSBR Single Acting Square Head Compact Cylinder PSBR12X30U the Right Cylinder?
This 12 mm bore with a 30 mm stroke outputs 42.9 N net push at 0.5 MPa. If you need less force, the Ø10 bore provides 29.8 N at the same pressure; stepping up to the Ø16 bore yields 74.8 N. The internal spring dictates a 0.2 MPa minimum pressure before motion begins and guarantees the rod springs back to a fail-safe retracted position on air loss.
Secure the cylinder via the direct M5x0.8 front-cover thread, ensuring proper bolt engagement. This specific configuration includes a U-style 90-degree side inlet for flat routing and lacks a sensor magnet. If your application requires powered extension and retraction, consider the PBR double-acting series instead.
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 PSBR12X30U FAQ
It delivers 42.9 N of net usable push at 0.5 MPa and 65.5 N at the 0.7 MPa maximum. Because it is spring-return, a minimum of 0.2 MPa is required to overcome the spring before the rod extends.
The actuator bolts directly via an M5x0.8 front-cover thread, removing the need for brackets. The SUS316L stainless barrel provides corrosion resistance in a slim pen-size body, and the U-style back cover offers a 90-degree side inlet for flat pneumatic routing.
