Airtac PBJ Adjustable Pen-Type Cylinder PBJ12X150-30S
The AirTAC Airtac PBJ Adjustable Pen-Type Cylinder PBJ12X150-30S is a double-acting, double-rod pen-size mini cylinder whose rear rod carries a stroke adjuster. On a Ø12mm bore it gives a nominal 150mm stroke with a 30mm fine-adjustable window — settable from 120 to 150mm, so you set the end position without changing hardware.

About the Airtac PBJ Adjustable Pen-Type Cylinder PBJ12X150-30S
The AirTAC PBJ12X150-30S is a double-acting, double-rod pen-size mini cylinder with a 12 mm bore and a 150 mm nominal stroke. A rear adjuster screw and lock nut let you trim the retract end, yielding an effective stroke range of 120-150 mm without changing hardware. The extend end remains fixed. The air port is M5x0.8, and the rod-end thread is M10x1.0.
This -S variant includes a built-in piston magnet for reed or electronic switches. The slim SUS304 stainless body saves space in tight jigs. The fixed TPU bumper decelerates the last few mm of travel; at high speeds with real tooling mass, meter-out the exhaust or add an external shock absorber.

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 (Ø12mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 46.7 N | 46.7 N |
| 0.7 MPa (max) | 65.4 N | 65.4 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 PBJ12X150-30S Is Used
Variable-Depth Insertion
Dial in precise insertion depths on the machine without ordering new cylinders, using the 120-150 mm retract adjustment to test multiple part heights.
Changeover Fixtures
Switch product profiles rapidly by turning the rear screw to shorten the return stroke, perfectly adapting end-of-arm tooling to new dimensions.
Trial Stop Positioning
Set exact trial stop locations during commissioning, locking the nut once the ideal 120-150 mm effective length is found for the workpiece.
Is the Airtac PBJ Adjustable Pen-Type Cylinder PBJ12X150-30S the Right Cylinder?
The Ø5 mm rod handles coaxial thrust well, but over a 150 mm stroke or under off-axis loads, add an external linear bearing to prevent side-load wear.
Only the retract position is field-settable; the extend end is fixed. Always re-tighten the lock nut after setting the M5x0.8 adjuster screw to prevent vibration drift. Confirm your ordering essentials: 12 mm bore, 150 mm stroke, 30 mm window, S magnet, and mounting option.
Quick checklist
- ✓ Need to fine-tune the end position on site
- ✓ Retract end sits within 120–150 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 PBJ12X150-30S FAQ
At 0.5 MPa, the push force is 56.5 N and the pull force is 46.7 N. At the maximum 0.7 MPa operating pressure, push is 79.1 N and pull is 65.4 N. The effective stroke range is 120-150 mm, achieved by shortening the retract end up to 30 mm from the 150 mm nominal stroke.
A rear M5x0.8 adjuster screw shortens the retract end, while the extend end remains fixed. You must re-tighten the lock nut after setting to prevent vibration drift. The built-in magnet works with reed or electronic switches and does not alter the double-acting force.
