Airtac PBJ Adjustable Pen-Type Cylinder PBJ12X100-40S
The AirTAC Airtac PBJ Adjustable Pen-Type Cylinder PBJ12X100-40S 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 PBJ12X100-40S
The AirTAC PBJ12X100-40S is a double-acting, double-rod pen-size mini cylinder with a 40mm adjustable window. A rear M5x0.8 adjuster screw and lock nut shorten the retract end, giving an effective stroke range of 60 to 100mm. The extend end remains fixed.
The Ø5mm stainless rod and barrel suit tight jigs and light end-of-arm tooling. A fixed TPU bumper cushions each end. Because the rod is slender, use an external guide for off-axis loads over long strokes.

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 PBJ12X100-40S Is Used
Changeover Fixtures
Dial in the retract distance from 60 to 100mm during product changeovers without swapping out the entire actuator hardware.
Trial Insertion Stops
Fine-tune the penetration depth on test jigs by turning the rear screw, hitting the exact 60-100mm target before locking down.
Variable Depth Pressing
Set precise end positions for light pressing tasks, relying on the fixed TPU bumper to cushion the last few millimeters of travel.
Is the Airtac PBJ Adjustable Pen-Type Cylinder PBJ12X100-40S the Right Cylinder?
If you need less force, the 10mm bore offers 39.3N; if you need more, the 16mm bore provides 100.5N. Remember that only the retract position is field-settable; the extend end is fixed. Always re-tighten the lock nut after setting the rear screw, as vibration can drift an unlocked adjuster. Confirm your ordering essentials: 12mm bore, 100mm stroke, 40mm window, S magnet, and any LB or FA mount.
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 PBJ12X100-40S FAQ
The effective stroke range is 60 to 100mm. The air port is M5x0.8.
The rear M5x0.8 screw shortens only the retract end; the extend end is fixed. Re-tighten the lock nut after setting to prevent vibration drift. The S option provides a built-in piston magnet for reed or electronic switches.
