The AirTAC Airtac PSBR Single Acting Square Head Compact Cylinder PSBR6X30R 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, 30mm stroke; the return spring resets the rod when air is released.
The AirTAC PSBR6X30R is a single-acting push, spring-return pen-size mini cylinder. It supplies 10.6 N of net push at 0.5 MPa, extending when air enters the single M5x0.8 port. The internal spring automatically retracts the rod on air loss, ensuring a fail-safe retracted hold.
This model features a direct M3x0.5 front-cover mounting thread, allowing it to bolt straight into compact fixtures without extra brackets. The SUS316L stainless barrel suits damp or washdown environments, while the fixed TPU bumper decelerates the rod at stroke ends. Plan for a safe working load of about 6 N, which is roughly 60% of the rated force, to account for seal friction.

| 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 (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.

Mounting: direct front-cover thread (M3×0.5). Related PBR-family variants: PBR (double acting), PTBR (single-acting pull).
Pushes lightweight electrical panels into a test socket. The direct front mount saves space, while the spring safely retracts the pin if air pressure drops.
Ejects small plastic parts from a conveyor line. The SUS316L barrel handles humid factory air, and the fail-safe retract prevents jamming on air loss.
Releases a small machining clamp using 10.6 N of push. The fixed TPU bumper softens the extend stroke, protecting delicate workpieces from impact.
Choose the PSBR6X30R for light-duty pushing where a fail-safe retracted position is required. At 0.5 MPa it yields 10.6 N of net push; if your application requires slightly more force, stepping up to the Ø8 bore provides 18.7 N. Because the return spring sets a minimum operating pressure of 0.3 MPa, ensure your air supply can overcome this threshold before motion begins.
This cylinder mounts directly via its M3x0.5 front-cover thread, and the R axial inlet keeps plumbing in-line. The thin Ø3 mm piston rod is built for coaxial thrust; over this 30 mm stroke, add an external guide if the load is off-axis to prevent side loading. Confirm your ordering essentials: no magnet is included, and the back cover uses the R axial configuration.
Quick checklist
The net push force is 10.6 N at 0.5 MPa and 16.3 N at the maximum 0.7 MPa. Because it is a single-acting push cylinder with a return spring, it requires a minimum operating pressure of 0.3 MPa to extend the rod.
It mounts directly via an M3x0.5 thread on the front cover, eliminating the need for separate brackets. The barrel is made of SUS316L stainless steel, offering excellent corrosion resistance for compact jigs.
