Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X80-75
The AirTAC Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X80-75 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 75mm fine-adjustable window — settable from 5 to 80mm, so you set the end position without changing hardware.

About the Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X80-75
The AirTAC PBJ16X80-75 is a double-acting, double-rod pen-size mini cylinder with an 80 mm nominal stroke and a 75 mm adjustable window. A rear screw and lock nut shorten the retract end, giving an effective stroke range of 5-80 mm. The extend end remains fixed. The M5x0.8 port and SUS304 stainless build ensure reliable operation.
This adjustable design lets you fine-tune travel directly on the machine without ordering new hardware. The fixed TPU bumper decelerates the piston near stroke end. For higher speeds with real tooling mass, meter-out the exhaust or add an external shock absorber. The Ø5 mm piston 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.
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 PBJ16X80-75 Is Used
Variable-Depth Pressing
Dial in exact insertion depths on the fly. The 5-80 mm retract window allows quick changes between part variants without swapping cylinders.
Changeover Fixtures
Adapt clamping positions rapidly during product changeovers. Field-set the stroke to match new workpiece dimensions directly on the machine.
Trial Stop Positioning
Set precise end-of-stroke stops for prototyping and test rigs. The rear adjuster screw allows incremental tuning without hardware modifications.
Is the Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X80-75 the Right Cylinder?
Stepping down to a 12 mm bore drops push to 56.5 N, while a larger 20 mm bore yields higher force.
Remember that only the retract position is adjustable; the extend end is fixed. Always re-tighten the lock nut after setting the rear M5x0.8 adjuster screw to prevent vibration drift. Confirm your ordering essentials: 16 mm bore, 80 mm stroke, 75 mm window, and any mounting options (LB/FA).
Quick checklist
- ✓ Need to fine-tune the end position on site
- ✓ Retract end sits within 5–80 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 PBJ16X80-75 FAQ
The effective stroke range is 5-80 mm.
A rear M5x0.8 adjuster screw shortens the retract end, while the extend end remains fixed. You must re-tighten the lock nut after setting your desired travel to prevent vibration drift.
