Airtac PBJ Adjustable Pen-Type Cylinder PBJ10X80-50
The AirTAC Airtac PBJ Adjustable Pen-Type Cylinder PBJ10X80-50 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 50mm fine-adjustable window — settable from 30 to 80mm, so you set the end position without changing hardware.

About the Airtac PBJ Adjustable Pen-Type Cylinder PBJ10X80-50
The AirTAC PBJ10X80-50 is a double-acting, single-rod pen-size mini cylinder with a 50mm adjustable-stroke window. A rear adjuster screw and lock nut shorten the retract end, giving an effective stroke range of 30-80mm. You can tune the travel directly on the machine during commissioning. The extend end remains fixed.
Output force matches the standard PB body, meaning the adjuster carries zero force penalty. It delivers about 39.3N push at 0.5MPa. The air port is M5x0.8, and the rod-end thread is M8x1.0. A fixed TPU bumper decelerates the last few millimeters of travel. The Ø4mm stainless rod suits coaxial thrust; add an external guide for off-axis loads.

| Series | PBJ JIS pen-size adjustable-stroke cylinder |
| Bore size | Ø10 mm |
| Rod diameter | Ø4 mm |
| Nominal stroke | 80 mm |
| Adjustable window | 50 mm (30–80 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 PBJ10X80-50 Is Used
Changeover Fixtures
Dial in the exact retract distance when swapping product families on a shared jig, using the 30-80mm window to avoid machining new stops.
Trial Insertion Stops
Set precise insertion depths during R&D or process development, tweaking the rear screw to test different engagement lengths on the fly.
Variable Depth Push
Adjust the retract stroke to push varying package flap sizes or labels without replacing the cylinder body across different SKU runs.
Is the Airtac PBJ Adjustable Pen-Type Cylinder PBJ10X80-50 the Right Cylinder?
This 10mm bore provides 39.3N push and 33N pull at 0.5MPa. If you need less force, the series lacks a smaller bore, so consider a different AirTAC family. If you need more force, step up to the 12mm bore for 56.5N push. Remember that only the retract position is settable here; the extend end is fixed. After dialing in your 30-80mm range, re-tighten the lock nut so vibration does not drift the screw. Confirm ordering essentials: 10mm bore, 80mm nominal stroke, 50mm window, no magnet, and your mounting choice.
For sizing, plan for a safe working load of roughly 24N, which is about 60% of the 39.3N rated push at 0.5MPa. For vertical lifts, expect to lift about 2kg with a sane 2:1 margin. This plain cylinder does not hold position on air loss; the piston drifts without live pressure, so use an external stop for fail-safe holding.
Quick checklist
- ✓ Need to fine-tune the end position on site
- ✓ Retract end sits within 30–80 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 PBJ10X80-50 FAQ
The effective stroke range is 30-80mm. At 0.5MPa it provides 39.3N push and 33N pull. At the maximum 0.7MPa operating pressure it provides 55N push and 46.2N pull. Adjusting the travel does not alter these forces.
The M4x0.7 rear screw shortens only the retract end; the extend end is fixed. You must re-tighten the lock nut after setting to prevent vibration drift. A plain cylinder does not hold its load on air loss—the piston drifts and the fixed TPU bumper only decelerates near stroke end.
