Airtac PBJ Adjustable Pen-Type Cylinder PBJ10X80-10
The AirTAC Airtac PBJ Adjustable Pen-Type Cylinder PBJ10X80-10 is a double-acting pen-size mini cylinder with a rear adjuster screw that shortens the retract end of the stroke. On a Ø10mm bore it gives a nominal 80mm stroke with a 10mm fine-adjustable window — settable from 70 to 80mm, so you set the end position without changing hardware.

About the Airtac PBJ Adjustable Pen-Type Cylinder PBJ10X80-10
The AirTAC PBJ10X80-10 is a double-acting, single-rod pen-size mini cylinder with an adjustable stroke. A rear M4x0.7 adjuster screw lets you shorten the retract end, providing an effective stroke range of 70-80 mm. The extend end remains fixed. Output force equals a standard PB cylinder of the same bore, delivering about 39.3 N push at 0.5 MPa with zero penalty for adding adjustability.
Built with a SUS304 stainless rod and barrel, the slim 10 mm body saves space in tight jigs. The M5x0.8 air port and fixed TPU bumper suit compact automation. Because the rod is only Ø4 mm, use an external guide for off-axis loads over long strokes. The bumper only decelerates the last few mm, so meter-out the exhaust or add a shock absorber when cycling real tooling mass at higher speeds.

|---|---|
| Series | PBJ JIS pen-size adjustable-stroke cylinder |
| Bore size | Ø10 mm |
| Rod diameter | Ø4 mm |
| Nominal stroke | 80 mm |
| Adjustable window | 10 mm (70–80 mm) |
| Adjuster thread | M4×0.7 |
| 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 100 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 (Ø10mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 39.3 N | 33.0 N |
| 0.7 MPa (max) | 55.0 N | 46.2 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 PBJ10X80-10 Is Used
Variable-Depth Insertion
Dial in precise press depths for different parts on the same line. The 70-80 mm retract window allows quick changeover without swapping cylinders.
Changeover Fixtures
Adapt pick-and-place stops rapidly during product changeovers. Field-set the exact retract position to match new part heights instantly.
Trial Stop Positioning
Fine-tune end-of-stroke limits during prototype runs. Adjust the rear screw to find the optimal motion profile before finalizing hard stops.
Is the Airtac PBJ Adjustable Pen-Type Cylinder PBJ10X80-10 the Right Cylinder?
This 10 mm bore provides 39.3 N push at 0.5 MPa. If you need less force, a smaller option lacks the power, while a 12 mm bore gives 56.5 N push. For sizing, plan for a safe working load of roughly 24 N (about 60% of the 0.5 MPa figure) to account for friction. Vertically, it lifts about 2 kg with a 2:1 margin.
Remember that only the retract 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: 10 mm bore, 80 mm nominal stroke, 10 mm window, no magnet, and mounting choice.
Quick checklist
- ✓ Need to fine-tune the end position on site
- ✓ Retract end sits within 70–80 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 PBJ10X80-10 FAQ
The effective stroke range is 70-80 mm. Force is unchanged from a standard PB cylinder: 39.3 N push and 33 N pull at 0.5 MPa, or 55 N push and 46.2 N pull at the 0.7 MPa maximum.
A rear M4x0.7 screw shortens the retract end only; the extend end is fixed. Re-tighten the lock nut after setting to prevent vibration drift. The cylinder does not hold position on air loss—the piston drifts—so use an external rod lock for fail-safe holding.
