The AirTAC Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X90-30 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 90mm stroke with a 30mm fine-adjustable window — settable from 60 to 90mm, so you set the end position without changing hardware.
The AirTAC PBJ16X90-30 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 60-90mm. You can tune the travel on the machine during commissioning without ordering new hardware. The extend end remains fixed.
Output force matches the standard PB body exactly, free of any penalty from the adjuster. The bore is 16mm, the air port is M5x0.8, and the rod-end thread is M10x1.0. A fixed TPU bumper decelerates the last few mm of travel.

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).
Switch product families on a line by dialing the retract stroke from 60 to 90mm instead of rebuilding the jig.
Set provisional end positions during prototyping to find the exact insertion depth before locking the nut.
Press parts to different depths on the same tool by adjusting the rear screw within the 30mm window.
Stepping down to a 12mm bore drops the push force to 56.5N, while moving up to a larger body increases it further. Pick the 16mm size if the 12mm capacity is insufficient. Remember that only the retract position is settable; the extend end is fixed. After dialing in the 60-90mm range, re-tighten the lock nut so vibration cannot drift the M5x0.8 adjuster screw. Confirm your ordering essentials: 16mm bore, 90mm nominal stroke, 30mm window, no magnet, and your mounting choice.
The Ø5mm rod is built for coaxial thrust. Over this 90mm stroke or with off-axis loads, add an external guide or linear bearing to prevent side load damage. This plain cylinder does not hold position on air loss; the piston drifts. Use an external stop or rod lock for a fail-safe hold.
Quick checklist
The effective stroke range is 60-90mm.
A rear M5x0.8 screw shortens the retract end up to 30mm, while the extend end is fixed. You must re-tighten the lock nut after setting to prevent vibration drift.
