Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X35-10
The AirTAC Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X35-10 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 35mm stroke with a 10mm fine-adjustable window — settable from 25 to 35mm, so you set the end position without changing hardware.

About the Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X35-10
The AirTAC PBJ16X35-10 is a double-acting, single-rod pen-size mini cylinder with a 10mm adjustable window. A rear M5x0.8 adjuster screw and lock nut shorten the retract end, giving an effective stroke range of 25-35mm. You set the exact return position on the machine without ordering new hardware. The extend end remains fixed. Output force equals a standard PB cylinder of the same bore, delivering 100.5N push and 90.7N pull at 0.5MPa. The M5x0.8 air port, Ø5mm rod, and M10x1.0 rod-end thread are fixed by the 16mm bore.
The slim SUS304 stainless body saves space in tight jigs. A fixed TPU bumper at each end decelerates the last few millimeters of travel. For practical sizing, plan for a safe working load of about 60N (roughly 60% of the 0.5MPa push figure) to account for seal friction. This computes to lifting about 5.1kg vertically with a sane 2:1 margin. The thin Ø5mm rod is built for coaxial thrust, so add an external guide for off-axis loads. At higher speeds with real tooling mass, the bumper may bottom out, requiring meter-out exhaust flow control or an external shock absorber.

| Rod diameter | Ø5 mm |
| Nominal stroke | 35 mm |
| Adjustable window | 10 mm (25–35 mm) |
| Adjuster thread | M5×0.8 |
| Port size | M5×0.8 |
|---|---|
| Operating pressure | 0.15 – 0.7 MPa |
| Proof pressure | 1.2 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 50 – 800 mm/s |
| Cushion | Elastic bumper (both ends) |
| Max standard stroke | Up to 200 mm |
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 PBJ16X35-10 Is Used
Changeover Fixtures
Dial in the exact 25-35mm retract position during product changeovers without swapping cylinders or machining new stop blocks.
Trial Stops
Fine-tune the return depth on test rigs to find the optimal engagement distance before finalizing a machine layout.
Variable-Depth Insert
Adjust the back position for different insertion depths on light-duty assembly tooling while maintaining 100.5N of push force.
Is the Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X35-10 the Right Cylinder?
To size correctly, consider the neighboring bores. Dropping to a 12mm bore gives 56.5N push at 0.5MPa, while stepping up is not available in this pen series, making the 16mm bore the top choice for maximum thrust. Remember that only the retract end is adjustable; the extend position is fixed. Always re-tighten the lock nut after setting the rear screw, as vibration can drift an unlocked mechanism. Confirm your ordering essentials: 16mm bore, 35mm nominal stroke, 10mm window, no magnet, and any LB or FA mounting accessories required.
Quick checklist
- ✓ Need to fine-tune the end position on site
- ✓ Retract end sits within 25–35 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 PBJ16X35-10 FAQ
The effective stroke range is 25-35mm (35mm nominal minus the 10mm window). Forces are 100.5N push and 90.7N pull at 0.5MPa, and 140.7N push and 126.9N pull at the 0.7MPa maximum operating pressure.
The M5x0.8 rear screw shortens only the retract end of the stroke, leaving the extend end fixed. You must re-tighten the lock nut after setting the desired position to prevent vibration drift. This adjustment changes stroke length without reducing the cylinder's output force.
