The AirTAC Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X150-50 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 150mm stroke with a 50mm fine-adjustable window — settable from 100 to 150mm, so you set the end position without changing hardware.
The AirTAC PBJ16X150-50 is a double-acting, double-rod pen-size mini cylinder with a 50mm adjustable stroke window. A rear adjuster screw shortens the retract end, giving an effective stroke range of 100-150mm. The extend end remains fixed.
The slim body features a SUS304 stainless barrel and a fixed TPU bumper at each end. The M5x0.8 air port and M10x1.0 rod-end thread match the 16mm bore standard. The Ø5mm rod is built for coaxial thrust, so over this 150mm length add an external guide to prevent side-load wear.

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 exact press-in depths for different product variants on the same jig using the 100-150mm effective range.
Quickly reset the retract length for new part heights without disassembling the cylinder or ordering new hardware.
Fine-tune end positions during machine commissioning to find the exact travel before locking the nut.
To size correctly, compare this 16mm bore against its neighbours. Stepping down to a 12mm bore drops the 0.5MPa push force to 56.5N, whereas this 16mm unit provides 100.5N. Remember that only the retract position is field-settable; the extend end is fixed. Always re-tighten the lock nut after tuning the screw to prevent vibration drift. Confirm your ordering essentials: 16mm bore, 150mm nominal stroke, 50mm window, and any mount accessories.
Quick checklist
The effective stroke range is 100-150mm.
The rear screw shortens the retract end only; the extend end is fixed. You must re-tighten the lock nut after setting to prevent vibration drift. A plain cylinder does not hold position on air loss, so use an external stop for fail-safe load holding.
