The AirTAC Airtac PSBR Single Acting Square Head Compact Cylinder PSBR12X15SU 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.
The AirTAC PSBR12X15SU is a JIS pen-size single-acting push cylinder that extends via one M5x0.8 air port and retracts via an internal spring. It supplies 42.9 N of net push at 0.5 MPa, with the return spring force already deducted. A fail-safe design ensures the rod pulls home on air loss, requiring just one solenoid line.
The direct M5x0.8 front-cover thread bolts straight to your jig, saving space, while the SUS316L stainless barrel suits damp environments. It includes a built-in magnet for position sensing and a fixed TPU bumper.

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.
| 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.

|---|---|
| 12 | Bore size in mm. |
| ×15 | 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 (M5×0.8). Related PBR-family variants: PBR (double acting), PTBR (single-acting pull).
Pushes light machined clips out of a fixture using 42.9 N of net force, with the spring safely pulling the rod back when air pressure drops.
Bolts directly via the M5x0.8 front thread to nudge thin electronic panels into place, while the SUS316L barrel handles humid cleanroom air.
Uses the single-acting push stroke to overcome a light mechanical latch, relying on the fail-safe retract design to open the clamp on air loss.
This 12 mm bore provides 42.9 N net push at 0.5 MPa and 65.5 N at 0.7 MPa. If you need less force, the 10 mm bore yields 29.8 N at 0.5 MPa; for heavier tasks, the 16 mm bore offers 74.8 N. The internal spring sets a 0.2 MPa minimum pressure before motion begins. The U suffix adds a 90-degree side inlet for flat plumbing, and the S suffix enables reed or electronic switches.
The direct front-mount M5x0.8 thread eliminates extra brackets. Because the 5 mm rod is slender, use an external guide for off-axis loads. The fixed TPU bumper only decelerates the last few millimeters, so meter-out the exhaust if moving heavy tooling at mid speed.
Quick checklist
The net push force is 42.9 N at 0.5 MPa and 65.5 N at the 0.7 MPa maximum. Because it is spring-return, a minimum pressure of 0.2 MPa is required to overcome the spring before the rod extends.
It mounts directly via an M5x0.8 thread on the front cover, removing the need for separate brackets. The S suffix indicates a built-in piston magnet compatible with reed or electronic switches for precise position detection.
