The AirTAC Airtac PSBR Single Acting Square Head Compact Cylinder PSBR10X50SR is a single acting, push type (spring return) pen-size mini cylinder with direct front-cover mounting (M4×0.7 thread). A single air port drives the push stroke on a Ø10mm bore, 50mm stroke; the return spring resets the rod when air is released.
The AirTAC PSBR10X50SR is a JIS pen-size single-acting push cylinder with a 50 mm stroke. Air entering the M5x0.8 port extends the rod, while an internal spring retracts it automatically. This fail-safe design ensures the rod returns home on air loss. It delivers 29.8 N of net push at 0.5 MPa, with the return spring force already deducted.
The slim SUS316L stainless body bolts directly to your fixture via the front-cover M4x0.7 thread, saving space in tight assemblies. A built-in magnet (-S) enables position sensing with reed or electronic switches. The fixed TPU bumper absorbs end-of-stroke impacts, and the R axial inlet keeps plumbing perfectly in line.

| Stroke | 50 mm |
| Acting type | Single acting, push type (spring return) |
| Front-mount thread | M4×0.7 |
| 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 60 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 (M4×0.7); barrel is SUS316L. Forces below are NET spring-deducted values. Confirm against the product label.
| Pressure | Net push force |
|---|---|
| 0.5 MPa | 29.8 N |
| 0.7 MPa (max) | 45.5 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.

|---|---|
| 10 | Bore size in mm. |
| ×50 | Stroke length in mm. |
| S | Built-in magnet for magnetic-switch position sensing (omit = no magnet). |
| U / R | Back cover: U 90° side inlet or R axial inlet (bore-dependent). |
Mounting: direct front-cover thread (M4×0.7). Related PBR-family variants: PBR (double acting), PTBR (single-acting pull).
Extends to push a lightweight panel into a machining nest, with the spring safely retracting the 4 mm rod when air is removed.
Mounts via the front M4x0.7 thread over a belt to push finished parts off the line, relying on fail-safe retract to clear the path.
Holds a workpiece by extending against it, then releases instantly on air loss as the spring pulls the rod back to clear the fixture.
This 10 mm bore provides 29.8 N net push at 0.5 MPa and 45.5 N at the 0.7 MPa maximum. If you need less force, the 8 mm bore yields 18.7 N at 0.5 MPa; for heavier jobs, the 12 mm bore offers 42.9 N. The internal spring requires a minimum 0.2 MPa pressure to overcome its resistance before motion begins.
The direct front-cover M4x0.7 thread mounts straight to your tooling. The 50 mm stroke is well within the 60 mm single-acting limit for this bore. Because the rod is a slender 4 mm, add an external guide for off-axis loads over this long stroke. Confirm you need the R axial inlet and the built-in magnet when ordering.
Quick checklist
It provides 29.8 N net push at 0.5 MPa and 45.5 N at the 0.7 MPa maximum. The internal return spring sets a 0.2 MPa minimum pressure needed before the rod can extend, ensuring fail-safe retraction on air loss.
It mounts directly via the front-cover M4x0.7 thread, eliminating brackets for compact jigs. The -S suffix indicates a built-in piston magnet compatible with reed or electronic switches. The SUS316L barrel suits damp environments.
