Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X65-10S
The AirTAC Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X65-10S 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 65mm stroke with a 10mm fine-adjustable window — settable from 55 to 65mm, so you set the end position without changing hardware.

About the Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X65-10S
The AirTAC PBJ16X65-10S is a double-acting, single-rod pen-size mini cylinder with a 10mm adjustable stroke window. A rear adjuster screw and lock nut let you shorten the retract end, yielding an effective stroke range of 55-65mm. 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 built-in magnet works with reed or electronic switches.
This JIS pen-size body features a SUS304 stainless rod and barrel, plus a fixed TPU bumper at each end. The M5x0.8 air port and M10x1.0 rod-end thread match standard PB hardware. Because the Ø5mm rod is designed for coaxial thrust, you should add an external guide for any off-axis loads over long strokes. The fixed bumper only decelerates the last few millimeters, so meter-out the exhaust or use an external shock absorber when cycling heavy tooling at high speeds.

| Bore size | Ø16 mm |
| Rod diameter | Ø5 mm |
| Nominal stroke | 65 mm |
| Adjustable window | 10 mm (55–65 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 |

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 PBJ16X65-10S Is Used
Insertion Depth Tuning
Dial in exact press-in depths for pins or plugs during prototype runs. Adjust the retract from 55 to 65mm on the machine without swapping hardware.
Changeover Fixtures
Quickly reposition the end-of-stroke stop when switching product families on a shared jig. The rear screw allows fast, tool-free length adjustments.
Vertical Lift Stops
Set precise lift heights for light actuators. With a 2:1 safety margin, this cylinder lifts about 5.1kg vertically, and the lock nut holds the setting.
Is the Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X65-10S the Right Cylinder?
Selecting this 16mm bore model gives you 100.5N of push force at 0.5MPa. If your application requires less force, stepping down to a 12mm bore provides 56.5N. For heavier demands, moving up is an option, though 16mm is the largest pen-size in this family. Remember that only the retract position is field-adjustable; the extend stroke is fixed. After setting your 55-65mm range, re-tighten the lock nut to prevent vibration drift. Confirm your ordering essentials: 16mm bore, 65mm nominal stroke, 10mm window, S magnet, and any LB or FA mounts.
Quick checklist
- ✓ Need to fine-tune the end position on site
- ✓ Retract end sits within 55–65 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 PBJ16X65-10S FAQ
At 0.5MPa, push force is 100.5N and pull is 90.7N. At the maximum 0.7MPa, push is 140.7N and pull is 126.9N. The nominal stroke is 65mm with a 10mm adjustable window, giving an effective stroke range of 55-65mm.
The rear M5x0.8 adjuster screw shortens only the retract end; the extend end is fixed. You must re-tighten the lock nut after setting to prevent vibration drift. The built-in magnet works with reed or electronic switches and does not alter the cylinder's force output.
