Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X60-20
The AirTAC Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X60-20 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 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, double-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.
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.

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 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?
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 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 PBJ16X60-20 FAQ
The effective stroke range is 40-60mm. 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.
