The AirTAC Airtac PBJ Adjustable Pen-Type Cylinder PBJ12X100-30 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 30mm fine-adjustable window — settable from 70 to 100mm, so you set the end position without changing hardware.
The AirTAC PBJ12X100-30 is a double-acting, double-rod pen-size mini cylinder with a 30mm adjustable window. A rear screw and lock nut shorten the retract end, giving an effective stroke range of 70-100mm. The extend end remains fixed.
The Ø12mm bore uses an M5x0.8 port and an M10x1.0 rod-end thread. A fixed TPU bumper cushions each end.

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.

Fixed body — no separate back-cover code. Mounting accessories: LB, FA. Related PB-family variants: PB (fixed stroke), PBD (double rod), PBR (front-mount).
Dial in the retract stop between 70-100mm when swapping product families on a shared jig, eliminating hardware changes.
Fine-tune the back position during prototyping to find the exact insertion depth before locking the nut down.
Adjust the retract end on the fly for cartons of different heights, relying on the fixed TPU bumper for end-of-travel deceleration.
If you need less force, the 10mm bore offers 39.3N; for more power, the 16mm bore gives 100.5N. Remember that only the retract position is field-settable; the extend end is fixed. Always re-tighten the lock nut after tuning to prevent vibration drift.
Confirm your ordering essentials: bore, stroke, window, magnet, and mount. This model has no magnet. The thin Ø5mm rod handles coaxial thrust well, but over long strokes or with off-axis loads, add an external linear bearing to prevent side-load damage.
Quick checklist
At 0.5MPa, push force is 56.5N and pull force is 46.7N. At the maximum 0.7MPa, push is 79.1N and pull is 65.4N. The nominal stroke is 100mm, and the rear adjuster provides an effective range of 70-100mm.
The M5x0.8 rear screw shortens only the retract end of the stroke; the extend end is fixed. You must re-tighten the lock nut after setting your desired position to prevent vibration drift.
