Airtac PBJ Adjustable Pen-Type Cylinder PBJ12X10-10S
The AirTAC Airtac PBJ Adjustable Pen-Type Cylinder PBJ12X10-10S 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 10mm stroke with a 10mm fine-adjustable window, so you set the end position without changing hardware.

About the Airtac PBJ Adjustable Pen-Type Cylinder PBJ12X10-10S
The AirTAC PBJ12X10-10S is a double-acting, double-rod pen-size mini cylinder with a 10mm adjustable window. A rear M5x0.8 adjuster screw shortens the retract end, providing an effective stroke range of 0 to 10mm. The extend end is fixed. It features a built-in piston magnet for solid-state or reed switches.
The slim SUS304 stainless body saves space in tight jigs. A fixed TPU bumper cushions the last few millimeters of travel. The thin Ø5mm rod handles coaxial thrust; use an external guide for any off-axis loads.

| 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 |

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 PBJ12X10-10S Is Used
Changeover Fixtures
Dial in the exact retract length during product changeovers without swapping physical hardware.
Trial Stops
Fine-tune the back position for prototype testing and trial stops before finalizing a layout.
Variable Insert Depth
Adjust the effective stroke from 0 to 10mm for pressing tasks needing slight depth variations.
Is the Airtac PBJ Adjustable Pen-Type Cylinder PBJ12X10-10S the Right Cylinder?
Remember that only the back position is tunable—the extend end is fixed. Always re-tighten the lock nut after setting the rear screw to prevent vibration drift. Confirm your ordering essentials: 12mm bore, 10mm stroke, 10mm window, S magnet, and your preferred mounting option.
Note that a plain cylinder does not hold position on air loss; the piston drifts without live pressure. For fail-safe load holding, specify an external stop or rod lock. The air port for this 12mm bore is M5x0.8.
Quick checklist
- ✓ Need to fine-tune the end position on site
- ✓ Retract end sits within 0–10 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 PBJ12X10-10S FAQ
The effective stroke range is 0 to 10mm. At 0.5MPa, push force is 56.5N and pull is 46.7N. At the maximum 0.7MPa operating pressure, push is 79.1N and pull is 65.4N.
The rear M5x0.8 screw shortens only the retract end, while the extend end remains fixed. You must re-tighten the lock nut after setting your desired length to prevent vibration drift.
