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

About the Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X60-20
The AirTAC PBJ16X60-20 is a double-acting, single-rod pen-size mini cylinder with a 20mm adjustable window. A rear M5x0.8 adjuster screw and lock nut shorten the retract end, giving an effective stroke range of 40-60mm. The extend end remains fixed. Output force matches a standard PB body, delivering 100.5N push and 90.7N pull at 0.5MPa.
The slim SUS304 stainless body saves space in tight jigs. It uses an M5x0.8 air port and an M10x1.0 rod-end thread. A fixed TPU bumper decelerates the last few millimeters of travel. For lifting tasks, plan for a safe working load of about 60N, which lifts roughly 5.1kg vertically with a 2:1 margin.

| Model | Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X60-20 |
|---|---|
| Series | PBJ JIS pen-size adjustable-stroke cylinder |
| Bore size | Ø16 mm |
| Rod diameter | Ø5 mm |
| Nominal stroke | 60 mm |
| Adjustable window | 20 mm (40–60 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 PBJ16X60-20 Is Used
Variable-Depth Insertion
Dial in precise press depths during prototype runs. Set the retract from 60mm down to 40mm without swapping cylinders.
Changeover Fixtures
Adapt pick-and-place positions for different product sizes rapidly using the rear adjuster screw to tune the stroke.
Trial Stop Positioning
Set exact stopping points for testing new assemblies. Lock the nut firmly to maintain the 40-60mm range setting.
Is the Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X60-20 the Right Cylinder?
This 16mm bore provides 100.5N push at 0.5MPa. If you need less force, the 12mm bore offers 56.5N push; if you need more, consider external stops as 16mm is the largest pen-size option. Remember that only the back position is tunable, so verify your extend end layout.
Always re-tighten the lock nut after setting the rear screw to prevent vibration drift. Confirm your ordering essentials: 16mm bore, 60mm nominal stroke, 20mm window, and any mounting accessories like LB or FA. The thin Ø5mm rod handles coaxial thrust well, but add a linear bearing for off-axis loads.
Quick checklist
- ✓ Need to fine-tune the end position on site
- ✓ Retract end sits within 40–60 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 PBJ16X60-20 FAQ
The effective stroke range is 40-60mm. At 0.5MPa it provides 100.5N push and 90.7N pull. At the 0.7MPa maximum, it yields 140.7N push and 126.9N pull. Adjusting the stroke does not alter these force figures.
The rear M5x0.8 screw shortens only the retract end, while the extend end is fixed. You must re-tighten the lock nut after setting your desired length to prevent vibration drift. This cylinder does not have a sensor magnet.
