Airtac PSBR Single Acting Square Head Compact Cylinder PSBR12X60R
The AirTAC Airtac PSBR Single Acting Square Head Compact Cylinder PSBR12X60R 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, 60mm stroke; the return spring resets the rod when air is released.

About the Airtac PSBR Single Acting Square Head Compact Cylinder PSBR12X60R
The AirTAC PSBR12X60R is a JIS pen-size single-acting push cylinder with a 12mm bore and 60mm stroke. It generates 42.9 N of net push at 0.5 MPa and 65.5 N at 0.7 MPa. A built-in return spring ensures the rod retracts safely on air loss. The R suffix designates an axial air inlet for inline plumbing.
This model mounts directly via its front-cover M5x0.8 thread, eliminating brackets to save space. The slim SUS316L stainless barrel suits damp environments, while a fixed TPU bumper cushions the stroke ends. Plan for a safe working load of about 26 N (roughly 60% of the 0.5 MPa rating) to account for seal friction.

| Stroke | 60 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 PSBR12X60R Is Used
Part Ejection
Pushes finished parts out of a machining fixture using 42.9 N of force, with the spring automatically pulling the rod back to clear the workspace.
Panel Pusher
Extends 60mm to index lightweight panels along a guide rail, relying on the direct front-cover thread for tight jig integration.
Clamp Release
Overcomes a holding mechanism to release a workpiece, defaulting to a locked retract state during compressed air dropouts.
Is the Airtac PSBR Single Acting Square Head Compact Cylinder PSBR12X60R the Right Cylinder?
When sizing this 12mm bore unit, compare it to adjacent options. The 10mm version yields 29.8 N at 0.5 MPa, while the 16mm bore provides 74.8 N. This PSBR12X60R sits comfortably in the middle at 42.9 N. For vertical lifts, expect to raise about 2.2 kg safely with a 2:1 margin. The 60mm stroke is well within the 75mm maximum for this bore.
Remember the M5x0.8 air port is separate from the identical M5x0.8 front-mounting thread. Because the 5mm rod is slender over a 60mm extension, use an external guide to prevent side loading. Confirm your axial inlet orientation and front-mount engagement before ordering.
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 PSBR12X60R FAQ
The net push force is 42.9 N at 0.5 MPa and 65.5 N at 0.7 MPa. Because it is spring-return, a minimum pressure of 0.2 MPa is required before the rod can extend.
It mounts directly via an M5x0.8 thread on the front cover. The R suffix indicates an axial back cover inlet, and the separate air port is also M5x0.8.
