Airtac PBJ Adjustable Pen-Type Cylinder PBJ12X100-40
The AirTAC Airtac PBJ Adjustable Pen-Type Cylinder PBJ12X100-40 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 100mm stroke with a 40mm fine-adjustable window — settable from 60 to 100mm, so you set the end position without changing hardware.

About the Airtac PBJ Adjustable Pen-Type Cylinder PBJ12X100-40
The AirTAC PBJ12X100-40 is a double-acting, double-rod pen-size mini cylinder with a 40mm adjustable stroke window. A rear adjuster screw shortens the retract end, giving an effective stroke range of 60-100mm. The extend end is fixed.
The slim SUS304 stainless body saves space in tight jigs. A fixed TPU bumper cushions both ends. The Ø5mm rod is for coaxial thrust, so add an external guide for off-axis loads over this long stroke.

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 PBJ12X100-40 Is Used
Changeover Fixtures
Dial in the exact retract distance from 60 to 100mm when switching between product families on a single base plate.
Trial Stops
Set precise end positions during prototype testing without machining new hard stops or ordering alternate cylinders.
Variable Depth Insertion
Screw the rear adjuster in or out to change the retract point for pressing parts to different depths on the fly.
Is the Airtac PBJ Adjustable Pen-Type Cylinder PBJ12X100-40 the Right Cylinder?
The air port is M5x0.8 and the rod-end thread is M10x1.0. Only the retract end is adjustable; re-tighten the lock nut after setting to prevent vibration drift. Confirm your bore, nominal stroke, 40mm window, and mounting accessories.
Quick checklist
- ✓ Need to fine-tune the end position on site
- ✓ Retract end sits within 60–100 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 PBJ12X100-40 FAQ
The effective stroke range is 60-100mm. At 0.5MPa the push force is 56.5N and the pull force is 46.7N. At the maximum 0.7MPa operating pressure, the push force is 79.1N and the pull force is 65.4N.
The M5x0.8 adjuster screw shortens only the retract end of the stroke; the extend end remains fixed. You must re-tighten the lock nut after setting your desired length to prevent vibration drift.
