Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X150-40S
The AirTAC Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X150-40S 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 40mm fine-adjustable window — settable from 110 to 150mm, so you set the end position without changing hardware.

About the Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X150-40S
The AirTAC PBJ16X150-40S is a double-acting, adjustable-stroke pen-size mini cylinder. A rear adjuster screw with an M5x0.8 thread shortens the retract end, giving an effective stroke range of 110-150mm. The extend end remains fixed. The air port is M5x0.8, and the rod-end thread is M10x1.0.
Built with a SUS304 stainless barrel and a slim 16mm body, it saves space in tight jigs. It includes a fixed TPU bumper at each end. The built-in magnet (-S) supports reed or electronic switches. Because the rod is a slender Ø5mm, use an external guide for off-axis loads over this long 150mm stroke.

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 PBJ16X150-40S Is Used
Changeover Fixtures
Dial in the exact retract length from 110mm to 150mm when switching product families on a shared jig, avoiding hardware swaps.
Trial Stops
Set precise intermediate end positions during R&D testing without ordering new cylinders, locking the nut once the correct depth is found.
Is the Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X150-40S the Right Cylinder?
Remember that only the retract end is field-adjustable from 110mm to 150mm, so set your exact back position and re-tighten the lock nut to prevent vibration drift. Confirm your ordering essentials: 16mm bore, 150mm nominal stroke, 40mm window, S magnet, and any LB or FA mounts.
Quick checklist
- ✓ Need to fine-tune the end position on site
- ✓ Retract end sits within 110–150 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 PBJ16X150-40S FAQ
The effective stroke range is 110-150mm. At 0.5MPa, push force is 100.5N and pull is 90.7N. At the maximum 0.7MPa operating pressure, push is 140.7N and pull is 126.9N.
A rear screw shortens the retract end only; the extend end is fixed. You must re-tighten the lock nut after setting to prevent vibration drift. A plain cylinder does not hold position on air loss, so an external rod lock is needed for fail-safe holding.
