Airtac PBJ Adjustable Pen-Type Cylinder PBJ12X150-100S
The AirTAC Airtac PBJ Adjustable Pen-Type Cylinder PBJ12X150-100S 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 100mm fine-adjustable window — settable from 50 to 150mm, so you set the end position without changing hardware.

About the Airtac PBJ Adjustable Pen-Type Cylinder PBJ12X150-100S
The AirTAC PBJ12X150-100S is a double-acting, double-rod pen-size mini cylinder with a 12mm bore and a 150mm nominal stroke. A rear adjuster screw and lock nut shorten the retract end, giving an effective stroke range of 50 to 150mm. You can set the exact length on the machine without changing hardware. The extend end remains fixed. The air port is M5x0.8, and the rod-end thread is M10x1.0.
The SUS304 stainless barrel and slim body fit tight jigs and light end-of-arm tooling. A fixed TPU bumper decelerates the last few millimeters of travel at both ends. Because the rod is only 5mm thick, add an external guide or linear bearing over this long stroke to prevent side-load damage. Good practice loads a cylinder to about 60% of its theoretical force, so plan for roughly 34N of real work at 0.5MPa.

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 PBJ12X150-100S Is Used
Changeover Fixtures
Dial in the retract stop from 50 to 150mm during product changeovers to avoid machining new hard stops.
Trial Stops
Set a temporary end position for prototype testing, then lock the nut to hold the exact 12mm bore position.
Variable-Depth Insert
Adjust the retract depth on the fly for inserting different part heights without swapping the cylinder.
Is the Airtac PBJ Adjustable Pen-Type Cylinder PBJ12X150-100S the Right Cylinder?
For this PBJ12X150-100S, remember that only the retract position is field-settable; the extend end is fixed. After dialing in your 50-150mm range, re-tighten the lock nut on the M5x0.8 adjuster thread so vibration does not drift the setting. Confirm your ordering essentials: 12mm bore, 150mm stroke, 100mm window, S magnet, and your mount choice.
Quick checklist
- ✓ Need to fine-tune the end position on site
- ✓ Retract end sits within 50–150 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 PBJ12X150-100S FAQ
The effective stroke range is 50 to 150mm.
The rear M5x0.8 screw shortens the retract end only; the extend end is fixed. Re-tighten the lock nut after setting to prevent drift. The -S suffix means a built-in piston magnet works with AirTAC reed or electronic switches.
