The AirTAC Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X40-10 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 40mm stroke with a 10mm fine-adjustable window — settable from 30 to 40mm, so you set the end position without changing hardware.
The AirTAC PBJ16X40-10 is a double-acting, adjustable-stroke pen-size mini cylinder. A rear adjuster screw shortens the retract end, giving an effective stroke range of 30-40mm. The extend end remains fixed.
The SUS304 stainless barrel and rod provide a slim profile for tight jigs. It features a fixed TPU bumper at each end and uses an M5x0.8 air port. The Ø5mm rod handles coaxial thrust; use 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.
| 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.

Fixed body — no separate back-cover code. Mounting accessories: LB, FA. Related PB-family variants: PB (fixed stroke), PBD (double rod), PBR (front-mount).
Dial in the 30-40mm retract length during product changeovers to hit new stops without machining replacement pins.
Fine-tune the back position for prototype testing, locking the nut once the exact 30-40mm motion is proven.
The M5x0.8 port matches the bore size.
Remember that only the retract position is field-settable. You must re-tighten the lock nut after tuning to prevent vibration drift. Confirm your ordering essentials: 16mm bore, 40mm nominal stroke, 10mm adjuster window, no magnet, and your preferred LB or FA mount.
Quick checklist
The effective stroke range is 30-40mm. Force is identical to a standard PB cylinder.
A rear M5x0.8 adjuster screw shortens the retract end by up to 10mm, while the extend end stays fixed. You must re-tighten the lock nut after setting to prevent vibration drift.
