Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X30-20SFA
The AirTAC Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X30-20SFA 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 30mm stroke with a 20mm fine-adjustable window — settable from 10 to 30mm, so you set the end position without changing hardware.

About the Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X30-20SFA
The AirTAC PBJ16X30-20SFA is a double-acting, double-rod pen-size mini cylinder with a 20mm adjustable window. A rear M5x0.8 adjuster screw shortens the retract end, giving an effective stroke range of 10-30mm. The FA mounting bracket provides a secure front interface, while the built-in magnet works with reed or electronic switches.
The Ø5mm stainless rod and barrel offer corrosion resistance in tight jigs. A fixed TPU bumper cushions each end. Because adjusting the back position does not alter internal pressure areas, thrust remains identical to the baseline hardware. The slim body uses an M5x0.8 air port.

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 PBJ16X30-20SFA Is Used
Variable-Depth Insertion
Dial in precise pressing depths on the fly without swapping hardware, using the 10-30mm retract tuning to test multiple insertion heights.
Changeover Fixtures
Rapidly adapt end-of-arm tooling for different product sizes by adjusting the back position via the M5x0.8 rear screw.
Trial Stop Positioning
Set exact retract stops during machine commissioning to find the optimal operating length before finalizing the layout.
Is the Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X30-20SFA the Right Cylinder?
The rear screw tunes the retract end only; the extend end remains fixed. Always re-tighten the lock nut after dialing in the 10-30mm range to prevent vibration drift. Confirm your ordering essentials: 16mm bore, 30mm nominal stroke, 20mm window, S magnet, and FA mount.
Quick checklist
- ✓ Need to fine-tune the end position on site
- ✓ Retract end sits within 10–30 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 PBJ16X30-20SFA FAQ
The effective stroke range is 10-30mm. 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 rear M5x0.8 screw shortens the retract end only; the extend end is fixed. You must re-tighten the lock nut after setting to stop vibration drift. The FA bracket provides a rigid front mounting face for secure fixture attachment.
