Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X80-50
The AirTAC Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X80-50 is a double-acting, double-rod pen-size mini cylinder whose rear rod carries a stroke adjuster. On a Ø16mm bore it gives a nominal 80mm stroke with a 50mm fine-adjustable window — settable from 30 to 80mm, so you set the end position without changing hardware.

About the Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X80-50
The AirTAC PBJ16X80-50 is a double-acting, double-rod pen-size mini cylinder with an adjustable stroke. A rear adjuster screw and lock nut shorten the retract end, giving an effective stroke range of 30 to 80 mm. The extend end remains fixed.
The slim SUS304 stainless body uses an M5x0.8 air port and an M10x1.0 rod-end thread. A fixed TPU bumper decelerates the last few mm of travel. The thin Ø5 mm piston rod is built for coaxial thrust, so add an external guide for off-axis loads.

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 (Ø16mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 90.7 N | 90.7 N |
| 0.7 MPa (max) | 126.9 N | 126.9 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 PBJ16X80-50 Is Used
Changeover Fixtures
Dial in the exact retract distance on the machine during product changeovers, saving time by avoiding hardware swaps.
Trial Stop Positioning
Set precise end-of-stroke stops for prototype testing, allowing quick adjustments to find the optimal process length.
Variable-Depth Insertion
Regulate the penetration depth of pins or plugs on assembly lines, easily tuning the 30 to 80 mm window on site.
Is the Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X80-50 the Right Cylinder?
Remember that only the retract position is field-settable—the extend end is fixed. Re-tighten the lock nut after setting the screw, as vibration can drift an unlocked adjuster.
Confirm your ordering essentials: 16 mm bore, 80 mm nominal stroke, 50 mm adjustable window, no magnet, and your preferred mounting. The fixed TPU bumper only decelerates near stroke end; at high speeds with heavy tooling, meter-out the exhaust or add an external shock absorber. A plain PBJ does not hold position on air loss, so use an external stop for fail-safe load holding.
Quick checklist
- ✓ Need to fine-tune the end position on site
- ✓ Retract end sits within 30–80 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 PBJ16X80-50 FAQ
The effective stroke range is 30 to 80 mm. At 0.5 MPa, the push force is 100.5 N and the pull force is 90.7 N. At the maximum 0.7 MPa operating pressure, the push force is 140.7 N and the pull force is 126.9 N.
The rear M5x0.8 adjuster screw shortens the retract end of the stroke, while the extend end remains fixed. You must re-tighten the lock nut after setting your desired length to prevent vibration drift. This cylinder has no sensor magnet.
