The AirTAC Airtac PSB Single Acting Compact Cylinder PSB12X10SU is a single acting, push type (spring return) pen-size mini cylinder with a Ø12mm bore and 10mm stroke. A single air port drives the push stroke; the built-in return spring resets the rod when air is released, so only one solenoid line is needed.
The AirTAC PSB12X10SU is a JIS pen-size single-acting push cylinder, meaning air entering the M5x0.8 port extends the rod while an internal spring retracts it. This fail-safe design ensures the rod returns home if air pressure drops. It provides 42.9 N of net push at 0.5 MPa and 65.5 N at 0.7 MPa.
The SUS304 stainless barrel and slim body fit tight jigs, while the U option provides a 90-degree side inlet for flat plumbing. A fixed TPU bumper decelerates the stroke at each end. The built-in -S magnet supports reed or electronic switches for position sensing.

|---|---|
| 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. Forces below are the NET spring-deducted values from the AirTAC thrust table. Confirm against the product label before installation.
| Pressure | Net push force |
|---|---|
| 0.5 MPa | 42.9 N |
| 0.7 MPa (max) | 65.5 N |
These are the usable push forces after the return spring is subtracted, taken directly 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.

Pushes finished metal parts out of a CNC machining center using a compact 10mm stroke that retracts safely on air loss.
Acts as a spring-return diverter on a packaging line, blocking items briefly before the fail-safe retract clears the path.
Holds a cardboard carton stationary for labeling, then releases the clamp instantly when the solenoid exhausts.
This 12mm bore generates 42.9 N net push at 0.5 MPa. Stepping down, the 10mm bore offers 29.8 N; stepping up, the 16mm bore provides 74.8 N. The internal spring sets a 0.2 MPa minimum pressure before motion begins. Plan for a safe working load of about 26 N, or lifting roughly 2.2 kg vertically with a 2:1 margin.
Confirm your ordering essentials: 12mm bore, 10mm stroke, S magnet, U side inlet, and mounting brackets. The Ø5 mm rod handles coaxial thrust well, but add an external guide for off-axis loads. At high speeds with heavy tooling, the TPU bumper may bottom out, so meter-out the exhaust or add a shock absorber.
Quick checklist
It delivers 42.9 N net push at 0.5 MPa and 65.5 N at 0.7 MPa. Because the internal spring opposes the air stroke, a minimum operating pressure of 0.2 MPa is required before the rod moves, and the rod fails safe to the retracted position on air loss.
The -S suffix indicates a built-in piston magnet for reed or electronic switches. Cushioning relies on a fixed TPU bumper at each end, which is not adjustable. For heavy tooling mass at high speeds, meter-out the exhaust or add an external shock absorber.
