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

About the Airtac PBJ Adjustable Pen-Type Cylinder PBJ12X150-50
The AirTAC PBJ12X150-50 is a double-acting, double-rod pen-size mini cylinder with a 50mm adjustable window. A rear M5x0.8 adjuster screw shortens the retract end, giving an effective stroke range of 100-150mm. The extend end remains fixed.
The slim SUS304 stainless body saves space in tight jigs. It uses an M5x0.8 air port and an M10x1.0 rod-end thread. A fixed TPU bumper decelerates the last few millimeters of travel.

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 PBJ12X150-50 Is Used
Variable-Depth Insertion
Dial in exact press depths for different parts on the same line. Set the retract from 100 to 150mm via the rear screw to switch profiles quickly without changing hardware.
Changeover Fixtures
Adapt pick-and-place tooling to new product lengths rapidly. The 50mm window allows operators to tune the retract end on the machine during setup.
Trial Stop Positioning
Find the optimal stopping point during prototyping. Adjust the back position incrementally, lock the nut, and test the cycle before finalizing the layout.
Is the Airtac PBJ Adjustable Pen-Type Cylinder PBJ12X150-50 the Right Cylinder?
Remember that only the retract position is adjustable from 100 to 150mm. The extend end is fixed. Always re-tighten the lock nut after setting the rear screw to prevent vibration drift.
Confirm your ordering essentials: 12mm bore, 150mm nominal stroke, 50mm window, no magnet, and mounting choice. The Ø5mm piston rod is built for coaxial thrust. Over this 150mm stroke, add an external guide or linear bearing to prevent side-load damage.
Quick checklist
- ✓ Need to fine-tune the end position on site
- ✓ Retract end sits within 100–150 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 PBJ12X150-50 FAQ
The effective stroke range is 100-150mm. Adjusting the stroke does not alter these forces.
A rear M5x0.8 screw shortens the retract end by up to 50mm. The extend end is fixed. You must re-tighten the lock nut after setting your desired length to prevent vibration drift. This model has no sensor magnet.
