Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X80-40
The AirTAC Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X80-40 is a double-acting pen-size mini cylinder with a rear adjuster screw that shortens the retract end of the stroke. 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.

About the Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X80-40
The AirTAC PBJ16X80-40 is a double-acting, single-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.
Output force equals a standard PB of the same 16mm bore, delivering 100.5N push and 90.7N pull at 0.5MPa. The slim SUS304 stainless body has a fixed TPU bumper at each end. Plan for a safe working load of about 60N (roughly 60% of the 0.5MPa push figure) to account for seal friction and smooth travel.

|---|---|
| Series | PBJ JIS pen-size adjustable-stroke cylinder |
| Bore size | Ø16 mm |
| Rod diameter | Ø5 mm |
| Nominal stroke | 80 mm |
| Adjustable window | 40 mm (40–80 mm) |
| Adjuster thread | M5×0.8 |
| Port size | M5×0.8 |
|---|---|
| Operating pressure | 0.15 – 0.7 MPa |
| Proof pressure | 1.2 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 50 – 800 mm/s |
| Cushion | Elastic bumper (both ends) |
| Max standard stroke | Up to 200 mm |
The adjuster shortens only the retract end; the extend end is fixed. Force is unchanged from the standard PB double-acting cylinder. Confirm the set position against the product label before installation.
Theoretical Output Force (Ø16mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 100.5 N | 90.7 N |
| 0.7 MPa (max) | 140.7 N | 126.9 N |
Adjusting the stroke does not change output force — these are the same values as the standard PB double-acting cylinder of the same bore. Size with a friction margin.

Where the Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X80-40 Is Used
Variable-Depth Insertion
Dial in the retract stop from 40 to 80mm to test different insertion depths on trial assemblies before finalizing the fixture.
Quick Changeover Fixtures
Swap product families and re-set the rear screw length on the fly, avoiding the need to physically replace cylinders between batches.
Adjustable Probe Stops
Set precise back positions for testing stations where the required probe travel distance varies by component height.
Is the Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X80-40 the Right Cylinder?
This 16mm bore provides 100.5N push at 0.5MPa. If you need less force, stepping down to a 12mm bore yields 56.5N push; stepping up is not available as 16mm is the largest pen-size option. 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
- ✓ Need to fine-tune the end position on site
- ✓ Retract end sits within 40–80 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 The adjuster shortens the retract end only.
- 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 PBJ16X80-40 FAQ
The effective stroke range is 40-80mm. At 0.5MPa it provides 100.5N push and 90.7N pull. At the maximum 0.7MPa operating pressure, it provides 140.7N push and 126.9N pull.
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.
