The AirTAC Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X80-40 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 40mm fine-adjustable window — settable from 40 to 80mm, so you set the end position without changing hardware.
The AirTAC PBJ16X80-40 is a double-acting, double-rod pen-size mini cylinder with a 40mm adjustable window. A rear M5x0.8 adjuster screw and lock nut shorten the retract end, giving an effective stroke range of 40-80mm. You tune the back position on the machine without buying new hardware. The extend end remains fixed.
The slim SUS304 stainless body has a fixed TPU bumper at each end.

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 retract stop from 40 to 80mm to test different insertion depths on trial assemblies before finalizing the fixture.
Swap product families and re-set the rear screw length on the fly, avoiding the need to physically replace cylinders between batches.
Set precise back positions for testing stations where the required probe travel distance varies by component height.
Remember that only the retract end is adjustable, so verify your extend position is fixed and correct.
The rod is a slender Ø5mm designed for coaxial thrust, so add an external guide or linear bearing for off-axis loads over this 80mm stroke. Confirm your ordering essentials: bore, stroke, window, and mounting (LB/FA). The air port is M5x0.8. Re-tighten the lock nut after setting the stroke to prevent vibration drift.
Quick checklist
The effective stroke range is 40-80mm.
A rear M5x0.8 screw shortens the retract end by up to 40mm, while the extend end is fixed. You must re-tighten the lock nut after setting your desired length to prevent vibration drift. This model does not include a sensor magnet.
