Airtac PBJ Adjustable Pen-Type Cylinder PBJ12X150-10
The AirTAC Airtac PBJ Adjustable Pen-Type Cylinder PBJ12X150-10 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 150mm stroke with a 10mm fine-adjustable window — settable from 140 to 150mm, so you set the end position without changing hardware.

About the Airtac PBJ Adjustable Pen-Type Cylinder PBJ12X150-10
The AirTAC PBJ12X150-10 is a JIS pen-size double-acting mini cylinder with a 10mm adjustable window. A rear M5x0.8 adjuster screw and lock nut shorten the retract end, giving an effective stroke range of 140-150mm. The extend end remains fixed. Output force matches a standard PB body, delivering 56.5N push and 46.7N pull at 0.5MPa.
The SUS304 stainless barrel and slim body fit tight jigs. It uses an M5x0.8 port and a fixed TPU bumper at each end. For vertical lifts, plan for about 2.9kg of payload with a 2:1 margin. The Ø5mm rod handles coaxial thrust; over this 150mm length, add an external guide to prevent side-load wear.

| Model | Airtac PBJ Adjustable Pen-Type Cylinder PBJ12X150-10 |
|---|---|
| Series | PBJ JIS pen-size adjustable-stroke cylinder |
| Bore size | Ø12 mm |
| Rod diameter | Ø5 mm |
| Nominal stroke | 150 mm |
| Adjustable window | 10 mm (140–150 mm) |
| Adjuster thread | M5×0.8 |
| Port size | M5×0.8 |
|---|---|
| Operating pressure | 0.15 – 0.7 MPa |
| Proof pressure | 1.2 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 50 – 800 mm/s |
| Cushion | Elastic bumper (both ends) |
| Max standard stroke | Up to 200 mm |
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 PBJ12X150-10 Is Used
Changeover Fixtures
Dial in the 140-150mm retract position during product family changeovers without machining new stops.
Trial Stops
Fine-tune the end position in test rigs to find the exact 140-150mm depth before finalizing a hard stop.
Variable Insertion
Adjust the back position for different insertion depths on light assembly tooling, keeping extend fixed.
Is the Airtac PBJ Adjustable Pen-Type Cylinder PBJ12X150-10 the Right Cylinder?
For sizing context, a 10mm bore yields 39.3N push at 0.5MPa, while a 16mm bore gives 100.5N. This 12mm unit provides a solid middle ground. Good practice loads a cylinder to roughly 60% of theoretical force, so expect about 34N of real work at 0.5MPa.
Remember that only the back position is tunable; the extend stroke is fixed. Re-tighten the lock nut after setting to prevent vibration drift. Confirm your bore, stroke, window, and mount before ordering.
Quick checklist
- ✓ Need to fine-tune the end position on site
- ✓ Retract end sits within 140–150 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 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 PBJ12X150-10 FAQ
The effective stroke is 140-150mm. It delivers 56.5N push and 46.7N pull at 0.5MPa, and 79.1N push and 65.4N pull at the 0.7MPa maximum.
The rear M5x0.8 screw shortens only the retract end; the extend end is fixed. You must re-tighten the lock nut after setting to prevent vibration drift.
