Airtac PBJ Adjustable Pen-Type Cylinder PBJ12X100-10
The AirTAC Airtac PBJ Adjustable Pen-Type Cylinder PBJ12X100-10 is a double-acting pen-size mini cylinder with a rear adjuster screw that shortens the retract end of the stroke. On a Ø12mm bore it gives a nominal 100mm stroke with a 10mm fine-adjustable window — settable from 90 to 100mm, so you set the end position without changing hardware.

About the Airtac PBJ Adjustable Pen-Type Cylinder PBJ12X100-10
The AirTAC PBJ12X100-10 is a double-acting, single-rod pen-size mini cylinder featuring a 10mm adjustable stroke window. A rear M5x0.8 adjuster screw shortens the retract end, yielding an effective stroke range of 90-100mm without changing hardware. The extend end remains fixed. Output force equals a standard PB body, delivering 56.5N push and 46.7N pull at 0.5MPa. The bore is 12mm, the piston rod is Ø5mm, and the air port is M5x0.8.
Built with a SUS304 stainless barrel and rod, this slim cylinder saves space in tight jigs. A fixed TPU bumper decelerates the last few millimeters of travel. Because the bumper is not a lock, the piston drifts on air loss; use an external stop for fail-safe holding. Plan for a safe working load of about 34N at 0.5MPa to account for seal friction and smooth travel.

| Nominal stroke | 100 mm |
| Adjustable window | 10 mm (90–100 mm) |
| Adjuster thread | M5×0.8 |
| Port size | M5×0.8 |
|---|---|
| Operating pressure | 0.15 – 0.7 MPa |
| Proof pressure | 1.2 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 50 – 800 mm/s |

The adjuster shortens only the retract end; the extend end is fixed. Force is unchanged from the standard PB double-acting cylinder. Confirm the set position against the product label before installation.
Theoretical Output Force (Ø12mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 56.5 N | 46.7 N |
| 0.7 MPa (max) | 79.1 N | 65.4 N |
Adjusting the stroke does not change output force — these are the same values as the standard PB double-acting cylinder of the same bore. Size with a friction margin.

Where the Airtac PBJ Adjustable Pen-Type Cylinder PBJ12X100-10 Is Used
Trial Stop Positioning
Dial in the exact retract distance during prototype runs. Adjust the 90-100mm window on the machine to find the optimal stop point before finalizing your fixture design.
Changeover Fixtures
Switch product variants quickly without swapping cylinder hardware. Turn the rear screw to shorten the retract stroke and accommodate different part heights on the same line.
Variable-Depth Insertion
Press or insert components to varying depths. Set the precise retract endpoint for delicate operations, relying on the 56.5N push force at 0.5MPa for consistent placement.
Is the Airtac PBJ Adjustable Pen-Type Cylinder PBJ12X100-10 the Right Cylinder?
This 12mm bore provides 56.5N push at 0.5MPa. If you need less force, the 10mm bore offers 39.3N push; for more thrust, the 16mm bore provides 100.5N push. Remember that only the retract position is field-settable; the extend end is fixed. After dialing in the 90-100mm range, re-tighten the lock nut to prevent vibration drift. Confirm your ordering essentials: bore, stroke, window, magnet, and mount.
The Ø5mm piston rod is built for coaxial thrust. Over the 100mm stroke, avoid side loading by adding an external guide or linear bearing. At higher speeds with real tooling mass, the fixed TPU bumper can bottom out, so meter-out the exhaust or fit an external shock absorber.
Quick checklist
- ✓ Need to fine-tune the end position on site
- ✓ Retract end sits within 90–100 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 The adjuster shortens the retract end only.
- 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 PBJ12X100-10 FAQ
The effective stroke range is 90-100mm. 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. Adjusting the stroke does not alter these force figures.
A rear M5x0.8 adjuster screw shortens the retract end of the stroke, while the extend end remains fixed. You set the effective stroke between 90 and 100mm, then re-tighten the lock nut to prevent vibration drift. This mechanism does not hold position on air loss.
