Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X150-20
The AirTAC Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X150-20 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 150mm stroke with a 20mm fine-adjustable window — settable from 130 to 150mm, so you set the end position without changing hardware.

About the Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X150-20
The AirTAC PBJ16X150-20 is a double-acting, single-rod pen-size mini cylinder with an adjustable stroke. A rear adjuster screw and lock nut shorten the retract end, giving an effective stroke range of 130-150mm. The extend end remains fixed. Output force stays identical to a standard PB body of this bore, delivering 100.5N push and 90.7N pull at 0.5MPa.
This 16mm bore actuator features a Ø5mm piston rod, an M5x0.8 air port, and an M10x1.0 rod-end thread. The SUS304 stainless barrel and slim body fit tight jigs. A fixed TPU bumper cushions each end. For vertical lifting, plan for about 5.1kg with a 2:1 safety margin. Over long strokes, the thin rod needs an external guide to prevent side load.

| Model | Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X150-20 |
|---|---|
| Series | PBJ JIS pen-size adjustable-stroke cylinder |
| Bore size | Ø16 mm |
| Rod diameter | Ø5 mm |
| Nominal stroke | 150 mm |
| Adjustable window | 20 mm (130–150 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 PBJ16X150-20 Is Used
Changeover Fixtures
Dial in the exact retract position for part changeovers without machining new hard stops or ordering different cylinders.
Trial Stops
Use the 130-150mm range to test end positions during process development before finalizing mechanical limits.
Variable Insertion
Adjust insertion depth on the fly for different material thicknesses while keeping the same fixed extend stroke.
Is the Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X150-20 the Right Cylinder?
When sizing this 16mm bore actuator, compare it against neighbours. Dropping to a 12mm bore yields 56.5N push at 0.5MPa, while moving up is not applicable here as 16mm is the largest PBJ bore. The 16mm provides 100.5N push at 0.5MPa, with a recommended safe working load of roughly 60N for smooth travel.
Remember that only the retract position is field-settable; the extend end is fixed. Always re-tighten the lock nut after setting the 130-150mm range to prevent vibration drift. Confirm your ordering essentials: 16mm bore, 150mm nominal stroke, 20mm window, and any required mounts.
Quick checklist
- ✓ Need to fine-tune the end position on site
- ✓ Retract end sits within 130–150 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 PBJ16X150-20 FAQ
At 0.5MPa it provides 100.5N push and 90.7N pull. At the 0.7MPa maximum, it yields 140.7N push and 126.9N pull. The rear adjuster screw provides an effective stroke range of 130-150mm.
The rear M5x0.8 adjuster screw only shortens the retract end; the extend end is fixed. Re-tighten the lock nut after setting to prevent drift. This plain cylinder does not hold position on air loss, so use an external stop for fail-safe load holding.
