Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X80-10
The AirTAC Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X80-10 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 10mm fine-adjustable window — settable from 70 to 80mm, so you set the end position without changing hardware.

About the Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X80-10
The AirTAC PBJ16X80-10 is a double-acting, single-rod pen-size mini cylinder with an adjustable stroke. A rear M5x0.8 adjuster screw and lock nut shorten the retract end, giving an effective stroke range of 70-80 mm from a nominal 80 mm. The extend end remains fixed. Output force is identical to a standard PB cylinder of this bore, delivering 100.5 N push at 0.5 MPa.
This 16 mm bore actuator features a Ø5 mm stainless steel rod, an M10x1.0 rod-end thread, and an M5x0.8 air port. A fixed TPU bumper at each end decelerates the last few mm of travel. Because the bumper is not a lock or brake, it cannot hold a load without live air pressure; plan for an external stop if you need fail-safe holding. The slim body saves space in tight jigs and light end-of-arm tooling.

|---|---|
| Series | PBJ JIS pen-size adjustable-stroke cylinder |
| Bore size | Ø16 mm |
| Rod diameter | Ø5 mm |
| Nominal stroke | 80 mm |
| Adjustable window | 10 mm (70–80 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 PBJ16X80-10 Is Used
Changeover Fixtures
Dial in the retract end from 70 to 80 mm during product changeovers without swapping hardware.
Trial Stops
Set precise end-of-stroke positions for prototype testing and dial in the exact 70-80 mm retract depth.
Variable-Depth Insertion
Tune the retract stop on the fly for pressing parts to varying depths on the same assembly jig.
Is the Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X80-10 the Right Cylinder?
For sizing, plan your real work for about 60 N of thrust at 0.5 MPa, which is roughly 60% of the theoretical 100.5 N push figure after accounting for seal friction. If you need to lift a part vertically, this actuator handles about 5.1 kg safely with a 2:1 margin. Stepping down to a 12 mm bore drops the 0.5 MPa push to 56.5 N, while moving up is required for heavier loads. Remember that only the retract position is tunable; the extend end is fixed. After setting your 70-80 mm stroke, re-tighten the lock nut so vibration does not drift the screw. Confirm your ordering essentials: 16 mm bore, 80 mm nominal stroke, 10 mm window, magnet, and mount.
Quick checklist
- ✓ Need to fine-tune the end position on site
- ✓ Retract end sits within 70–80 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 PBJ16X80-10 FAQ
The effective stroke range is 70-80 mm. At 0.5 MPa, push force is 100.5 N and pull is 90.7 N. At the maximum 0.7 MPa operating pressure, push is 140.7 N and pull is 126.9 N.
The rear M5x0.8 screw shortens only the retract end of the stroke, while the extend end remains fixed. You must re-tighten the lock nut after setting your desired length to prevent vibration drift.
