Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X75-30
The AirTAC Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X75-30 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 75mm stroke with a 30mm fine-adjustable window — settable from 45 to 75mm, so you set the end position without changing hardware.

About the Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X75-30
The AirTAC PBJ16X75-30 is a double-acting, double-rod pen-size mini cylinder with a 30mm adjustable window. A rear screw and lock nut shorten the retract end, giving an effective stroke range of 45-75mm. The extend end remains fixed. The M5x0.8 port and Ø5mm stainless rod handle pneumatic thrust efficiently.
Because tuning the screw trims only the back position, you can finalize travel on the machine without reordering hardware. The SUS304 barrel and fixed TPU bumper suit tight jigs and end-of-arm tooling.

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 PBJ16X75-30 Is Used
Changeover Fixtures
Dial in the 45-75mm retract position during product changeovers to align pressing tools without swapping out the entire cylinder body.
Trial Insertion Stops
Use the rear adjuster to test variable insertion depths on delicate components, backing off the stroke until the perfect contact force is found.
Variable Depth Pressing
Fine-tune the end-of-stroke position on light assembly lines to accommodate different material thicknesses on the fly.
Is the Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X75-30 the Right Cylinder?
For this 16mm bore, the Ø5mm rod is built for coaxial thrust, so over the 75mm stroke or under off-axis loads, add an external guide or linear bearing to prevent side-load wear. The thin rod is not for lateral forces.
Remember that only the retract end is settable; the extend position is fixed. Always re-tighten the lock nut after adjusting the rear M5x0.8 screw to prevent vibration drift. Confirm your ordering essentials: 16mm bore, 75mm nominal stroke, 30mm window, magnet option, and mount type.
Quick checklist
- ✓ Need to fine-tune the end position on site
- ✓ Retract end sits within 45–75 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 PBJ16X75-30 FAQ
The effective stroke range is 45-75mm. At 0.5MPa, the push force is 100.5N and the pull force is 90.7N. At the maximum 0.7MPa operating pressure, the push force is 140.7N and the pull force is 126.9N.
The rear M5x0.8 screw shortens only the retract end of the stroke; the extend end is fixed. You must re-tighten the lock nut after setting the desired length to prevent vibration drift. The cylinder does not hold position on air loss, so an external stop is needed for fail-safe load holding.
