Airtac PSBR Single Acting Square Head Compact Cylinder PSBR12X30R
The AirTAC Airtac PSBR Single Acting Square Head Compact Cylinder PSBR12X30R 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 PSBR12X30R
The AirTAC PSBR12X30R is a single-acting push pen cylinder that extends via air and retracts via an internal spring, ensuring a fail-safe home position on air loss. It supplies 42.9 N of net push at 0.5 MPa and 65.5 N at 0.7 MPa. The SUS316L stainless barrel suits damp environments while keeping the body slim.
It mounts directly via the front-cover M5x0.8 thread, eliminating brackets to save jig space. Air enters the M5x0.8 port to extend the rod, while a fixed TPU bumper decelerates the stroke. Plan for a safe working load of roughly 26 N to account for seal friction and smooth travel.

| 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 PSBR12X30R Is Used
Part Ejection
Uses the spring-return push to eject small machined parts from a fixture, guaranteeing the arm pulls back safely if air pressure drops.
Panel Pusher
Advances a light panel into a test station using the direct front-cover thread for a low-profile block mount.
Clamp Release
Overcomes a light spring clamp to release a workpiece, automatically securing the part again upon air loss.
Is the Airtac PSBR Single Acting Square Head Compact Cylinder PSBR12X30R the Right Cylinder?
This 12 mm bore provides 42.9 N net push at 0.5 MPa. If you need less force, the 10 mm bore yields 29.8 N; for heavier pushing, the 16 mm bore offers 74.8 N. The internal spring demands a minimum 0.2 MPa to move the rod.
The direct M5x0.8 front-cover thread secures the cylinder without extra hardware. This R variant features an axial air inlet for in-line plumbing. The thin 5 mm rod handles coaxial thrust, so add an external guide for any off-axis loads.
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 PSBR12X30R FAQ
It delivers 42.9 N net push at 0.5 MPa and 65.5 N at 0.7 MPa. The internal return spring sets a 0.2 MPa minimum pressure before the rod moves, and the cylinder fails safely retracted on air loss.
It bolts directly to a fixture via the front-cover M5x0.8 thread. The SUS316L stainless barrel provides corrosion resistance for damp environments, and this model lacks a sensor magnet.
