Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X80-30
The AirTAC Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X80-30 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 30mm fine-adjustable window — settable from 50 to 80mm, so you set the end position without changing hardware.

About the Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X80-30
The AirTAC PBJ16X80-30 is a double-acting, double-rod pen-size mini cylinder with a 30mm adjustable window. A rear adjuster screw and lock nut shorten the retract end, giving an effective stroke range of 50-80mm. Tuning the length on the machine avoids reordering hardware for changeovers. The extend end remains fixed.
The slim SUS304 stainless body includes a fixed TPU bumper at each end. The M5x0.8 air port and M10x1.0 rod-end thread keep fixtures compact. The thin Ø5mm rod handles coaxial thrust; over long strokes add an external guide to prevent side-load wear. The bumper only decelerates the last few millimetres, so at high speeds with real tooling mass, meter-out the exhaust or add a shock absorber.

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 PBJ16X80-30 Is Used
Changeover Fixtures
Dial in the retract stop from 50 to 80mm during product changeovers without machining new hard stops.
Trial Insertion Stops
Fine-tune the depth of a press fit in test jigs, locking the nut once the perfect position is found.
Is the Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X80-30 the Right Cylinder?
Remember the rear screw only adjusts the retract position; the extend end is fixed. Re-tighten the lock nut after setting to prevent vibration drift. Confirm your ordering essentials: 16mm bore, 80mm nominal stroke, 30mm window, no magnet, and mounting choice.
Quick checklist
- ✓ Need to fine-tune the end position on site
- ✓ Retract end sits within 50–80 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 PBJ16X80-30 FAQ
The nominal stroke is 80mm with a 30mm window, yielding an effective range of 50-80mm.
The rear screw shortens the retract end only; the extend end is fixed. You set the stroke from 50 to 80mm and then re-tighten the lock nut to prevent vibration drift. The cylinder does not hold position on air loss without an external stop.
