Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X30-30
The AirTAC Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X30-30 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 30mm stroke with a 30mm fine-adjustable window, so you set the end position without changing hardware.

About the Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X30-30
The AirTAC PBJ16X30-30 is a double-acting, double-rod pen-size mini cylinder with a 30 mm adjustable stroke window. A rear adjuster screw and lock nut shorten the retract end, giving an effective stroke range of 0-30 mm. The extend end remains fixed. It features a stainless steel barrel and rod, plus a fixed TPU bumper at each end. The air port is M5x0.8.
Tuning the length on the machine avoids re-ordering hardware for changeovers. For safe practice, plan for about 60 N of real work at 0.5 MPa to account for seal friction. The thin Ø5 mm rod handles 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 PBJ16X30-30 Is Used
Changeover Fixtures
Dial in the exact retract end-stop during product changeovers on a shared jig, setting the depth anywhere from 0 to 30 mm without swapping cylinders.
Trial Insertion Stops
Nail prototype insertion depths on light end-of-arm tooling by trimming the back position incrementally until the press fit is perfect.
Variable Depth Pressing
Adjust the retract margin on a compact assembly station to press pins to varying depths against a fixed bottomed extend position.
Is the Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X30-30 the Right Cylinder?
Remember that only the retract position is adjustable here; the extend end is fixed. After setting your 0-30 mm range, re-tighten the lock nut because vibration can drift an unlocked screw. Confirm ordering essentials: bore 16, stroke 30, window 30, and your preferred LB or FA mount.
Quick checklist
- ✓ Need to fine-tune the end position on site
- ✓ Retract end sits within 0–30 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 PBJ16X30-30 FAQ
The effective stroke range is 0-30 mm.
A rear M5x0.8 adjuster screw shortens the retract end only; the extend end is fixed. Re-tighten the lock nut after setting to prevent vibration drift. A plain cylinder does not hold position on air loss—the piston drifts, so use an external stop for a fail-safe hold.
