Airtac PBJ Adjustable Pen-Type Cylinder PBJ12X150-10S
The AirTAC Airtac PBJ Adjustable Pen-Type Cylinder PBJ12X150-10S 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 150mm stroke with a 10mm fine-adjustable window — settable from 140 to 150mm, so you set the end position without changing hardware.

About the Airtac PBJ Adjustable Pen-Type Cylinder PBJ12X150-10S
The AirTAC PBJ12X150-10S is a JIS pen-size double-acting mini cylinder with a 12mm bore and a 10mm adjustable window. A rear adjuster screw shortens the retract end, giving an effective stroke range of 140-150mm. You set the exact length right on the machine without ordering new hardware. The extend end remains fixed. It features a built-in piston magnet for position sensing.
The SUS304 stainless body and Ø5mm rod provide a slim profile for tight jigs. A fixed TPU bumper cushions the end caps.

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.

Is the Airtac PBJ Adjustable Pen-Type Cylinder PBJ12X150-10S the Right Cylinder?
Remember the rear screw only adjusts the retract position; the extend end is fixed. Always re-tighten the lock nut after setting your 140-150mm range to prevent vibration drift. Confirm your bore, nominal stroke, window, S magnet, and mounting choice before ordering.
Quick checklist
- ✓ Need to fine-tune the end position on site
- ✓ Retract end sits within 140–150 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 PBJ12X150-10S FAQ
The effective stroke range is 140-150mm. At 0.5MPa, push force is 56.5N and pull is 46.7N. At the maximum 0.7MPa, push is 79.1N and pull is 65.4N. The air port is M5x0.8 and the rod-end thread is M10x1.0.
The rear M5x0.8 screw shortens the retract end only; the extend end is fixed. You must re-tighten the lock nut after setting to prevent vibration drift. The S model includes a built-in piston magnet compatible with AirTAC reed or electronic switches.
