Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X150-75
The AirTAC Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X150-75 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 75mm fine-adjustable window — settable from 75 to 150mm, so you set the end position without changing hardware.

About the Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X150-75
The AirTAC PBJ16X150-75 is a double-acting, double-rod pen-size mini cylinder featuring a 75mm adjustable window. A rear adjuster screw with an M5x0.8 thread shortens the retract end, yielding an effective stroke range of 75-150mm. You can tune the stroke on the machine without swapping hardware. The extend end remains fixed. The air port is M5x0.8 and the rod-end thread is M10x1.0.
The slim SUS304 stainless body includes 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 PBJ16X150-75 Is Used
Changeover Fixtures
Dial in the retract stop from 75 to 150mm to adapt jig depth for different product runs without machining new hard stops.
Trial Insertion Stops
Fine-tune the penetration depth on test assemblies by adjusting the rear screw, locking the nut once the optimal travel is found.
Is the Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X150-75 the Right Cylinder?
When sizing, consider the neighbouring bores for your force needs. Remember that only the retract position is settable; the extend end is fixed. After dialing in your 75-150mm range, re-tighten the lock nut to prevent vibration drift. Confirm your ordering essentials: 16mm bore, 150mm nominal stroke, 75mm window, and mounting accessories (LB/FA).
Because the Ø5mm rod is slender, adding an external guide or linear bearing is recommended for this long 150mm stroke to prevent side-load deflection. The fixed TPU bumper only decelerates the final few millimeters, so meter-out the exhaust or use an external shock absorber when cycling at high speed with heavy tooling.
Quick checklist
- ✓ Need to fine-tune the end position on site
- ✓ Retract end sits within 75–150 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 PBJ16X150-75 FAQ
The effective stroke range is 75-150mm. At 0.5MPa the push force is 100.5N and the pull force is 90.7N. At the maximum 0.7MPa operating pressure, the push force is 140.7N and the pull force is 126.9N.
The rear M5x0.8 adjuster 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—the piston drifts and the fixed TPU bumper only decelerates near the stroke end, so use an external stop for fail-safe holding.
