Airtac PBJ Adjustable Pen-Type Cylinder PBJ12X150-50S
The AirTAC Airtac PBJ Adjustable Pen-Type Cylinder PBJ12X150-50S 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 PBJ12X150-50S
The AirTAC PBJ12X150-50S is a double-acting, double-rod pen-size mini cylinder with a 50mm adjustable-stroke window. A rear adjuster screw and lock nut shorten 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. The built-in magnet (-S) works with reed or electronic switches.

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 PBJ12X150-50S Is Used
Changeover Fixtures
Set different retract stops for product changeovers directly on the machine, avoiding hardware swaps.
Trial Stops
Dial in the exact 100-150mm back position during prototype testing before locking the adjuster nut.
Variable Depth Insert
Adjust the retract distance for pressing parts of varying heights without needing multiple cylinders.
Is the Airtac PBJ Adjustable Pen-Type Cylinder PBJ12X150-50S the Right Cylinder?
Remember that only the retract position is field-settable; the extend end is fixed. Always re-tighten the M5x0.8 adjuster lock nut after setting to prevent vibration drift.
Confirm your ordering essentials: 12mm bore, 150mm nominal stroke, 50mm window, S for the internal magnet, and your mounting choice. The Ø5mm rod is built for coaxial thrust, so over this 150mm stroke add an external guide or linear bearing for any off-axis loads.
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 PBJ12X150-50S FAQ
The effective stroke range is 100-150mm.
A rear screw shortens only the retract end; the extend end is fixed. You set the length from 100 to 150mm on the machine, then re-tighten the lock nut to prevent vibration drift.
