Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X150-20
The AirTAC PBJ Adjustable Pen-Type Cylinder PBJ16X150-20 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 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, double-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.
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. Over long strokes, the thin rod needs an external guide to prevent side load.

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 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.
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 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 PBJ16X150-20 FAQ
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.
