About the Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X30-30S
The AirTAC PBJ16X30-30S is a double-acting, double-rod pen-size mini cylinder featuring a 30mm adjustable stroke window. A rear M5x0.8 adjuster screw shortens the retract end, yielding an effective stroke range of 0-30mm without changing hardware. The extend end is fixed.
Built with a SUS304 stainless barrel and rod, this slim 16mm bore unit integrates a piston magnet for position sensing. It uses an M5x0.8 air port and a fixed TPU bumper at each end.

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 PBJ16X30-30S Is Used
Variable-Depth Insertion
Dial in precise pressing depths from 0 to 30mm on the fly for pins or plugs without swapping out the physical cylinder hardware.
Changeover Fixtures
Adapt a single jig to multiple part families quickly by turning the rear adjuster screw to set the exact retract position required.
Trial Stop Positioning
Use the built-in magnet for confirmation while tweaking the back position during prototype runs to find the optimal stopping point.
Is the Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X30-30S the Right Cylinder?
The rear screw alters only the back position; the extend end remains fixed. Always re-tighten the lock nut after setting your 0-30mm range to prevent vibration drift. Confirm ordering essentials: bore, stroke, window, S magnet, and mounting.
The Ø5mm rod handles coaxial thrust well, but add an external guide for off-axis loads. Because the fixed TPU bumper only decelerates the last few millimeters, meter-out the exhaust or add a shock absorber when cycling real tooling mass at high speeds.
Quick checklist
- ✓ Need to fine-tune the end position on site
- ✓ Retract end sits within 0–30 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 PBJ16X30-30S FAQ
The effective stroke range is 0-30mm. At the 0.7MPa maximum, push is 140.7N and pull is 126.9N. These figures exactly match a standard PB cylinder of the same bore.
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 prevent vibration drift. The S suffix indicates a built-in piston magnet compatible with AirTAC reed or electronic switches.
