The AirTAC Airtac PBJ Adjustable Pen-Type Cylinder PBJ12X100-10S is a double-acting, double-rod pen-size mini cylinder whose rear rod carries a stroke adjuster. On a Ø12mm bore it gives a nominal 100mm stroke with a 10mm fine-adjustable window — settable from 90 to 100mm, so you set the end position without changing hardware.
The AirTAC PBJ12X100-10S is a JIS pen-size double-acting mini cylinder with a 10mm adjustable-stroke window. A rear M5x0.8 adjuster screw shortens the retract end, giving an effective stroke of 90-100mm. The extend end remains fixed.
The slim SUS304 stainless body integrates a piston magnet for reed or electronic switches. It uses an M5x0.8 air port and a fixed TPU bumper at each end. The Ø5mm rod handles coaxial thrust; over this 100mm stroke, add an external guide if side loads are present.

PBJ is a double-rod cylinder: the rear rod carries the stroke adjuster, which sets the stroke end within the adjustable window. Confirm the set position against the product label before installation.
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 46.7 N | 46.7 N |
| 0.7 MPa (max) | 65.4 N | 65.4 N |
The rear rod passes through the rear cover, so both piston faces lose rod area: push is shown at the annular-area value (conservative), lower than a single-rod PB push of the same bore. Size with a friction margin.

Dial in the exact 90-100mm retract position during product changeovers without machining new stop spacers.
Fine-tune the end-of-stroke position during prototype testing to find the optimal insertion depth.
Adjust the back position on the fly for light-duty press tasks that require slight depth variations.
Remember that only the retract position is field-settable, so verify your extend end layout. Always re-tighten the lock nut after setting the 90-100mm range to prevent vibration drift. Confirm your ordering essentials: 12mm bore, 100mm nominal stroke, 10mm window, S magnet, and any LB or FA mounts.
Quick checklist
The effective stroke range is 90-100mm. At 0.5 MPa, push force is 56.5N and pull force is 46.7N. At the maximum 0.7 MPa operating pressure, push is 79.1N and pull is 65.4N.
A rear screw shortens only the retract end, while the extend end is fixed. You must re-tighten the lock nut after setting to prevent vibration drift. A plain cylinder does not hold its load on air loss; the piston drifts and the fixed TPU bumper only decelerates near the stroke end. Use an external rod lock for fail-safe holding.
