Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X150-30
The AirTAC Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X150-30 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 30mm fine-adjustable window — settable from 120 to 150mm, so you set the end position without changing hardware.

About the Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X150-30
The AirTAC PBJ16X150-30 is a double-acting, single-rod pen-size mini cylinder with a 30mm adjustable window. A rear screw and lock nut trim the retract end, giving an effective stroke range of 120-150mm. The extend end remains fixed. Output force stays identical to a standard PB body of the same bore, delivering 100.5N push and 90.7N pull at 0.5MPa. The slim SUS304 stainless body saves space in tight jigs.
This 16mm bore unit uses an M5x0.8 air port and an M10x1.0 rod-end thread. A fixed TPU bumper cushions the final few millimeters of travel at each end. For practical sizing, plan for a safe working load of about 60N, which is roughly 60% of the 0.5MPa theoretical push force. The Ø5mm piston rod handles coaxial thrust; over this long 150mm stroke, add an external guide to prevent side-load deflection.

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 PBJ16X150-30 Is Used
Changeover Fixtures
Dial in the exact retract distance when switching product families on a shared fixture, avoiding the need to swap physical spacers.
Trial Insertion Stops
Fine-tune insertion depth during process development, letting engineers test multiple positions rapidly before locking the nut.
Variable Depth Pressing
Adjust the rear screw to modify the end-of-stroke position for pressing parts of varying heights without changing the cylinder.
Is the Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X150-30 the Right Cylinder?
Selecting this model gives a 120-150mm stroke range. If you need less force, the 12mm bore variant provides 56.5N push at 0.5MPa. If your application requires more power, you would need to step outside the pen-size format. Remember that only the retract position is settable; the extend end is fixed. After dialing in your length, re-tighten the lock nut so vibration does not drift the screw. Confirm your ordering essentials: 16mm bore, 150mm nominal stroke, 30mm window, no magnet, and your preferred mount.
Quick checklist
- ✓ Need to fine-tune the end position on site
- ✓ Retract end sits within 120–150 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 PBJ16X150-30 FAQ
The effective stroke range is 120-150mm. At 0.5MPa, push force is 100.5N and pull force is 90.7N. At the maximum 0.7MPa operating pressure, push is 140.7N and pull is 126.9N.
A rear M5x0.8 adjuster screw shortens 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.
