Airtac PBJ Adjustable Pen-Type Cylinder PBJ12X150-75S
The AirTAC Airtac PBJ Adjustable Pen-Type Cylinder PBJ12X150-75S 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 75mm fine-adjustable window — settable from 75 to 150mm, so you set the end position without changing hardware.

About the Airtac PBJ Adjustable Pen-Type Cylinder PBJ12X150-75S
The AirTAC PBJ12X150-75S is a double-acting, double-rod pen-size mini cylinder with a 75mm adjustable stroke window. A rear M5x0.8 adjuster screw and lock nut shorten the retract end, giving an effective stroke range of 75mm to 150mm. The extend end remains fixed. The -S suffix denotes a built-in piston magnet for reed or electronic switches.
The slim SUS304 stainless body and Ø5mm rod suit tight jigs and end-of-arm tooling. Air connects via an M5x0.8 port. A fixed TPU bumper cushions each end. Because the rod is only 5mm thick over a long stroke, add an external linear bearing for any off-axis loads. The bumper only decelerates the final few millimeters, so meter-out the exhaust or use an external shock absorber when driving heavy tooling at high speed.

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 PBJ12X150-75S Is Used
Changeover Fixtures
Dial in the retract stop during product changeovers without machining new hard stops or ordering replacement cylinders.
Variable-Depth Insertion
Tune the 75-150mm stroke on the machine to press parts to exact depths during prototyping or batch variations.
Is the Airtac PBJ Adjustable Pen-Type Cylinder PBJ12X150-75S the Right Cylinder?
If your task needs less force, the 10mm bore yields 39.3N; if you need more, step up to the 16mm bore for 100.5N. To set your travel, turn the rear M5x0.8 adjuster screw to dial in the 75-150mm range, then re-tighten the lock nut so machine vibration does not drift the setting. Remember that only the retract position moves while the extend end stays fixed. Confirm your ordering essentials: 12mm bore, 150mm nominal stroke, 75mm window, S magnet, and any LB or FA mount.
Quick checklist
- ✓ Need to fine-tune the end position on site
- ✓ Retract end sits within 75–150 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 PBJ12X150-75S FAQ
The effective stroke range is 75mm to 150mm. Adjusting the travel does not alter these force figures.
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. A plain cylinder does not hold position on air loss, as the piston drifts and the fixed TPU bumper only decelerates near the end. Use an external rod lock for fail-safe holding.
