Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X60-40S
The AirTAC PBJ Adjustable Pen-Type Cylinder PBJ16X60-40S 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 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.
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.

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 PBJ16X60-40S 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
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?
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 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 PBJ16X60-40S 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.
