Airtac PBJ Adjustable Pen-Type Cylinder PBJ12X15-10S
The AirTAC Airtac PBJ Adjustable Pen-Type Cylinder PBJ12X15-10S is a double-acting pen-size mini cylinder with a rear adjuster screw that shortens the retract end of the stroke. On a Ø12mm bore it gives a nominal 15mm stroke with a 10mm fine-adjustable window — settable from 5 to 15mm, so you set the end position without changing hardware.

About the Airtac PBJ Adjustable Pen-Type Cylinder PBJ12X15-10S
The AirTAC PBJ12X15-10S is a JIS pen-size double-acting mini cylinder with a 12mm bore and a built-in magnet. A rear adjuster screw shortens the retract end, giving an effective stroke range of 5 to 15mm. You set the exact length on the machine without changing hardware. The extend end remains fixed.
Output force matches the standard PB series, delivering 56.5N push at 0.5MPa. The slim body features a SUS304 stainless barrel and a fixed TPU bumper. Plan for a safe working load of about 34N at 0.5MPa, which lets you lift roughly 2.9kg vertically with a 2:1 margin.

The adjuster shortens only the retract end; the extend end is fixed. Force is unchanged from the standard PB double-acting cylinder. Confirm the set position against the product label before installation.
Theoretical Output Force (Ø12mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 56.5 N | 46.7 N |
| 0.7 MPa (max) | 79.1 N | 65.4 N |
Adjusting the stroke does not change output force — these are the same values as the standard PB double-acting cylinder of the same bore. Size with a friction margin.

Where the Airtac PBJ Adjustable Pen-Type Cylinder PBJ12X15-10S Is Used
Changeover Fixtures
Dial in the exact retract stop during product changeovers without swapping physical spacers.
Trial Insertion Stops
Fine-tune insertion depth on test parts directly at the jig until the perfect position locks in.
Vertical Lift Jigs
Lift light components up to 2.9kg vertically using the magnetic piston for solid-state sensing.
Is the Airtac PBJ Adjustable Pen-Type Cylinder PBJ12X15-10S the Right Cylinder?
For lighter tasks, the 10mm bore offers 39.3N push at 0.5MPa. If you need more force, the 16mm bore provides 100.5N push. This 12mm bore gives 56.5N push and 46.7N pull at 0.5MPa. Remember that only the back position is adjustable. You must re-tighten the lock nut after setting the screw to prevent vibration drift. Confirm your bore, stroke, window, magnet, and mount before ordering. The air port is M5x0.8.
Quick checklist
- ✓ Need to fine-tune the end position on site
- ✓ Retract end sits within 5–15 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 The adjuster shortens the retract end only.
- 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 PBJ12X15-10S FAQ
The effective stroke range is 5-15mm. Force is 56.5N push and 46.7N pull at 0.5MPa, and 79.1N push and 65.4N pull at the 0.7MPa maximum.
The M5x0.8 rear screw shortens only the retract end; the extend end is fixed. Re-tighten the lock nut after setting to prevent drift. The built-in magnet works with reed or electronic switches.
