The AirTAC Airtac PBJ Adjustable Pen-Type Cylinder PBJ12X150-30 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 150mm stroke with a 30mm fine-adjustable window — settable from 120 to 150mm, so you set the end position without changing hardware.
The AirTAC PBJ12X150-30 is a double-acting, double-rod pen-size mini cylinder with a 30mm adjustable window. A rear M5x0.8 adjuster screw shortens the retract end, giving an effective stroke range of 120-150mm. The extend end remains fixed.
The slim SUS304 stainless body saves space in tight jigs. A fixed TPU bumper cushions each end. The Ø5mm rod handles coaxial thrust; add an external guide for off-axis loads.

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 precise retract distances for pressing pins or plugs during prototype runs, using the rear screw to test multiple depths without swapping cylinders.
Switch product families on a packaging line quickly by adjusting the effective stroke from 120 to 150mm on the machine to accommodate different part heights.
Set exact back stops for delicate electronic components, fine-tuning the retract end position during commissioning until the optimal travel is found.
Stepping down to a 10mm bore yields 39.3N, while a 16mm bore offers 100.5N. Choose based on your exact force needs. The M5x0.8 port matches the bore size. Remember the rear screw only tunes the back position; the extend end is fixed.
After dialing in the 120-150mm range, re-tighten the lock nut to prevent vibration drift. Confirm your ordering essentials: 12mm bore, 150mm nominal stroke, 30mm window, and mounting choice (LB or FA). No magnet is specified here.
Quick checklist
The effective stroke range is 120-150mm. Adjusting the stroke does not alter these force figures.
The rear M5x0.8 screw shortens only the retract end of the stroke; the extend end is fixed. You set the desired length between 120mm and 150mm, then re-tighten the lock nut to prevent vibration drift. The piston does not hold position on air loss, so use an external stop for fail-safe holding.
