Airtac PBJ Adjustable Pen-Type Cylinder PBJ12X15-10
The AirTAC Airtac PBJ Adjustable Pen-Type Cylinder PBJ12X15-10 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 15mm stroke with a 10mm fine-adjustable window — settable from 5 to 15mm, so you set the end position without changing hardware.

About the Airtac PBJ Adjustable Pen-Type Cylinder PBJ12X15-10
The AirTAC PBJ12X15-10 is a double-acting, double-rod pen-size mini cylinder with a 10mm adjustable stroke window. A rear adjuster screw and lock nut shorten the retract end, giving an effective stroke range of 5-15mm.
The extend end is fixed, meaning only the back position is tunable. The slim body features a SUS304 stainless barrel and rod, plus a fixed TPU bumper at each end. The integrated air port is M5x0.8. After setting your desired length, re-tighten the lock nut to prevent vibration drift.

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.
Theoretical Output Force (Ø12mm)
| 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.

Where the Airtac PBJ Adjustable Pen-Type Cylinder PBJ12X15-10 Is Used
Changeover Fixtures
Dial in the exact retract position when switching between product variants on a shared assembly jig, avoiding hardware swaps.
Trial Stops
Fine-tune the stopping point in 5-15mm increments during prototyping to find the optimal mechanical engagement depth.
Variable Insertion Depth
Set precise press-in distances for different components on the same line without changing out the entire actuator.
Is the Airtac PBJ Adjustable Pen-Type Cylinder PBJ12X15-10 the Right Cylinder?
This 12mm bore bridges that gap perfectly.
Remember that only the retract position is adjustable; the extend end is fixed. The Ø5mm rod is built for coaxial thrust, so add an external guide if your application involves off-axis loads. Confirm your ordering essentials: 12mm bore, 15mm nominal stroke, 10mm window, magnet option, and mounting hardware.
Quick checklist
- ✓ Need to fine-tune the end position on site
- ✓ Retract end sits within 5–15 mm
- ✓ Force at your working pressure
- ✓ Magnet (S) for sensors?
- ✓ Access to the rear adjuster screw
- ✓ Keep the load coaxial — avoid side load
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 0.7 MPa operating pressure.
- check Set the adjuster, then re-lock the check nut.
- check Double rod: the rear rod carries the stroke adjuster.
- check Keep the load coaxial; avoid side load on the thin rod.
- check Do not dismantle the front or back cover.
Airtac PBJ Adjustable Pen-Type Cylinder PBJ12X15-10 FAQ
The effective stroke range is 5-15mm. At 0.5MPa, the push force is 56.5N and the pull force is 46.7N. At the maximum operating pressure of 0.7MPa, the push force is 79.1N and the pull force is 65.4N.
A rear M5x0.8 adjuster screw shortens the retract end of the stroke up to 10mm, while the extend end remains fixed. This adjustment does not change the force, which equals a standard PB cylinder. Always re-tighten the lock nut after setting the position to prevent vibration drift.
