The AirTAC Airtac PSBR Single Acting Square Head Compact Cylinder PSBR6X50SR is a single acting, push type (spring return) pen-size mini cylinder with direct front-cover mounting (M3×0.5 thread). A single air port drives the push stroke on a Ø6mm bore, 50mm stroke; the return spring resets the rod when air is released.
The AirTAC PSBR6X50SR is a single-acting push pen cylinder with a 50 mm stroke. Air entering the M5x0.8 port extends the rod, while an internal spring retracts it. This fail-safe design ensures the rod returns home on air loss. It delivers about 10.6 N net push at 0.5 MPa.
The direct M3x0.5 front-cover mounting thread bolts straight to your fixture, saving space in tight jigs. The SUS316L stainless barrel suits damp environments. A fixed TPU bumper cushions the stroke ends. The built-in magnet works with reed or electronic switches.

| 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 (M3×0.5); barrel is SUS316L. Forces below are NET spring-deducted values. Confirm against the product label.
| Pressure | Net push force |
|---|---|
| 0.5 MPa | 10.6 N |
| 0.7 MPa (max) | 16.3 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.

|---|---|
| 6 | 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 (M3×0.5). Related PBR-family variants: PBR (double acting), PTBR (single-acting pull).
Uses the fail-safe retract to push light electronic components out of a machining fixture, ensuring the rod clears when air pressure drops.
Bolts directly via the M3x0.5 front thread to push a thin sensor panel into a test slot, saving space in compact testing arrays.
Employs the SUS316L barrel and slim body to actuate a low-force fluidic valve in damp laboratory enclosures without adding bulk.
This 6 mm bore provides 10.6 N net push at 0.5 MPa and 16.3 N at 0.7 MPa. Sizing both ways: a smaller bore is unavailable, while stepping up to an 8 mm bore yields 18.7 N at 0.5 MPa.
The return spring sets a 0.3 MPa minimum pressure before motion. The Ø3 mm rod is for coaxial thrust; over this 50 mm stroke, add an external guide to prevent side load. Confirm the M3x0.5 front-mount thread and R axial inlet for your plumbing.
Quick checklist
It provides 10.6 N net push at 0.5 MPa and 16.3 N at 0.7 MPa. Because it is spring-return, a minimum pressure of 0.3 MPa is required before the rod moves, and it fails safely retracted on air loss.
It mounts directly via a front-cover M3x0.5 thread. The included -S magnet is compatible with AirTAC reed or electronic switches for position sensing.
