Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X60-40S
The AirTAC Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X60-40S 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 60mm stroke with a 40mm fine-adjustable window — settable from 20 to 60mm, so you set the end position without changing hardware.

About the Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X60-40S
The AirTAC PBJ16X60-40S is a JIS pen-size double-acting mini cylinder with a 40mm adjustable window. A rear adjuster screw shortens the retract end, giving an effective stroke range of 20-60mm. You set the exact length on the machine without ordering new hardware. The extend end remains fixed. Output force equals a standard PB cylinder of this bore, delivering 100.5N push and 90.7N pull at 0.5MPa.
The slim SUS304 stainless body saves space in tight jigs. A fixed TPU bumper cushions the last few millimeters of travel at each end. The built-in piston magnet works with reed or electronic switches. Plan for a safe working load of about 60N, which is roughly 60% of the 0.5MPa push figure, to account for seal friction and smooth travel.

| Model | Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X60-40S |
|---|---|
| Series | PBJ JIS pen-size adjustable-stroke cylinder |
| Bore size | Ø16 mm |
| Rod diameter | Ø5 mm |
| Nominal stroke | 60 mm |
| Adjustable window | 40 mm (20–60 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 PBJ16X60-40S Is Used
Changeover Fixtures
Dial in the retract stroke from 20 to 60mm on the machine to switch product sizes without machining new stop collars.
Variable-Depth Insertion
Set precise press-in depths for different connectors using the rear screw, keeping the extend end fixed for a repeatable touch position.
Vertical Lift Jigs
Lifts about 5.1kg vertically with a 2:1 safety margin at 0.5MPa. Add an external guide for off-axis loads to protect the 5mm rod.
Is the Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X60-40S the Right Cylinder?
For sizing, the 12mm bore neighbor provides 56.5N push at 0.5MPa, while the 16mm bore gives 100.5N. If your load is under 56.5N, the smaller bore saves space; if you need closer to 100.5N, this 16mm unit is correct. Remember that the rear screw only adjusts the retract position. The extend end is fixed. Always re-tighten the lock nut after setting your stroke to prevent vibration drift. Confirm your ordering essentials: 16mm bore, 60mm nominal stroke, 40mm window, S magnet, and any LB or FA mount.
Quick checklist
- ✓ Need to fine-tune the end position on site
- ✓ Retract end sits within 20–60 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 PBJ16X60-40S FAQ
The effective stroke range is 20-60mm. At 0.5MPa, push force is 100.5N and pull is 90.7N. At the maximum 0.7MPa operating pressure, push is 140.7N and pull is 126.9N. The air port is M5x0.8 and the rod-end thread is M10x1.0.
A rear M5x0.8 adjuster screw shortens the retract end by up to 40mm. 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. Use an external rod lock for fail-safe holding.
