Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X150-40
The AirTAC Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X150-40 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 PBJ16X150-40
The AirTAC PBJ16X150-40 is a double-acting, double-rod pen-size mini cylinder with a 40 mm adjustable stroke window. A rear M5x0.8 adjuster screw shortens the retract end, yielding an effective stroke range of 110-150 mm. The extend end remains fixed.
Built with a SUS304 stainless barrel and rod, this slim 16 mm bore cylinder saves space in tight jigs. It uses an M5x0.8 air port and a fixed TPU bumper at each end.

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 PBJ16X150-40 Is Used
Variable-Depth Insertion
Dial in precise press depths for electronic pins or connectors during prototype runs, shifting the retract stop within the 110-150 mm window without swapping cylinders.
Quick Changeover Fixtures
Adapt pick-and-place end-of-arm tooling to new part heights rapidly by turning the rear screw, locking the nut, and resuming production immediately.
Trial Stop Positioning
Set temporary mechanical stops for testing component alignment in assembly jigs, fine-tuning the back position until the exact process length is proven.
Is the Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X150-40 the Right Cylinder?
Remember that the rear screw only tunes the back position; the extend stroke is fixed. Always re-tighten the lock nut after setting your 110-150 mm range to prevent vibration drift. Confirm your ordering essentials: 16 mm bore, 150 mm nominal stroke, 40 mm window, and any required LB or FA mount.
Because the rod is a slender Ø5 mm over a 150 mm stroke, it is built for coaxial thrust. Avoid side loads by adding an external guide or linear bearing for off-axis tooling. The fixed TPU bumper only decelerates the last few mm, so meter-out the exhaust or add an external shock absorber when cycling real tooling mass at higher speeds.
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 PBJ16X150-40 FAQ
The effective stroke range is 110-150 mm. At 0.5 MPa the 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. These figures exactly match a standard PB cylinder of the same bore.
The rear M5x0.8 screw shortens only the retract end; the extend end is fixed. You must re-tighten the lock nut after setting to prevent vibration drift. A plain cylinder does not hold its load on air loss—the piston drifts and the bumper only decelerates near stroke end, so use an external stop for a fail-safe hold.
