Airtac PSBR Single Acting Square Head Compact Cylinder PSBR12X15R
The AirTAC Airtac PSBR Single Acting Square Head Compact Cylinder PSBR12X15R 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, 15mm stroke; the return spring resets the rod when air is released.

About the Airtac PSBR Single Acting Square Head Compact Cylinder PSBR12X15R
The AirTAC PSBR12X15R is a single-acting push pen cylinder that extends via one M5x0.8 air port and retracts via an internal spring. It provides 42.9 N of net push at 0.5 MPa and 65.5 N at 0.7 MPa. The return spring ensures the rod moves safely back home on air loss, requiring only a single solenoid line.
You bolt this slim SUS316L stainless mini body straight to a fixture via the direct M5x0.8 front-cover thread. A fixed TPU bumper cushions the last few millimeters of travel. Plan for a safe working load of about 26 N, which is roughly 60 percent of the 0.5 MPa rating, to account for seal friction.

| Stroke | 15 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 PSBR12X15R Is Used
Part Ejector
Pushes machined pins out of a chuck using 42.9 N net force, with the spring pulling the rod back to clear the workspace.
Panel Pusher
Extends 15mm to nudge a lightweight electronic panel into a test nest, bolted directly via the M5x0.8 front thread.
Clamp Release
Overcomes a mechanical latch to release a clamped part, relying on the fail-safe retract to reset the latch on air loss.
Is the Airtac PSBR Single Acting Square Head Compact Cylinder PSBR12X15R the Right Cylinder?
This 12mm bore, 15mm stroke model offers 42.9 N net push at 0.5 MPa. Stepping down to the 10mm bore drops the usable push to 29.8 N, while moving up to the 16mm bore raises it to 74.8 N. Choose this size if your fixture needs moderate ejection force within a tight pen-size envelope.
The direct M5x0.8 front-mount thread integrates the mounting point into the front cover, eliminating separate brackets. The R back cover provides an axial air inlet for inline plumbing. The internal spring sets a 0.2 MPa minimum pressure before the rod moves, and the rod fails safe in the retracted position.
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 PSBR12X15R FAQ
The net push force is 42.9 N at 0.5 MPa and 65.5 N at 0.7 MPa. Because an internal spring returns the rod, a minimum pressure of 0.2 MPa is required before the cylinder extends.
The cylinder bolts directly to a fixture using an M5x0.8 front-cover thread, saving space without extra brackets. The SUS316L stainless barrel resists corrosion in damp environments, and the R cover provides an axial air inlet.
