About the Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X75-75S
The AirTAC PBJ16X75-75S is a double-acting, double-rod pen-size mini cylinder featuring a 75mm adjustable stroke window. A rear adjuster screw and lock nut shorten the retract end, giving an effective range of 0-75mm. You can set the exact stroke on the machine without ordering new hardware. The extend end remains fixed.
The Ø5mm piston rod has an M10x1.0 end thread, and the air port is M5x0.8. A built-in magnet works with reed or electronic switches. The slim SUS304 stainless body includes a fixed TPU bumper at each end. For real work, plan for a safe load of about 60N, which accounts for seal friction.

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.

Trial Stop Positioning
Fine-tune the backstop distance on testing jigs to find the exact contact point.
Is the Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X75-75S the Right Cylinder?
Remember that only the retract end is adjustable. After setting your 0-75mm range, re-tighten the lock nut so vibration does not drift the screw. The thin Ø5mm rod is for coaxial thrust, so add an external guide for off-axis loads. Confirm your bore, stroke, window, magnet, and mount before ordering.
Quick checklist
- ✓ Need to fine-tune the end position on site
- ✓ Retract end sits within 0–75 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 PBJ16X75-75S FAQ
The effective stroke range is 0-75mm.
A rear M5x0.8 adjuster screw shortens the retract end while the extend end stays fixed. You must re-tighten the lock nut after setting to prevent drift. The built-in magnet is compatible with reed or electronic switches.
