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

About the Airtac PBJ Adjustable Pen-Type Cylinder PBJ10X80-30
The AirTAC PBJ10X80-30 is a double-acting, single-rod pen-size mini cylinder with a 30mm rear adjuster window, yielding an effective stroke range of 50-80mm. A rear screw and lock nut shorten the retract end for on-machine tuning, while the extend end remains fixed. It delivers 39.3N push and 33N pull at 0.5MPa, matching standard PB force exactly.
Built with a SUS304 stainless barrel and rod, this slim JIS body uses an M5x0.8 air port and an M8x1.0 rod-end thread. The fixed TPU bumper decelerates the last few mm of travel. For practical sizing, plan for a safe working load of about 24N (roughly 60% of the 0.5MPa push force), which equates to lifting about 2kg vertically with a 2:1 margin.

| Model | Airtac PBJ Adjustable Pen-Type Cylinder PBJ10X80-30 |
|---|---|
| Series | PBJ JIS pen-size adjustable-stroke cylinder |
| Bore size | Ø10 mm |
| Rod diameter | Ø4 mm |
| Nominal stroke | 80 mm |
| Adjustable window | 30 mm (50–80 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 PBJ10X80-30 Is Used
Changeover Fixtures
Dial in the retract distance from 50 to 80mm on the machine to switch product families without machining new stop collars.
Trial Insertion Stops
Fine-tune the retracted tooling height during R&D or process trials, locking the nut once the ideal insertion depth is found.
Variable Depth Pressing
Set precise end-of-stroke positions for light pressing tasks, using the 39.3N push force at 0.5MPa to seat delicate components.
Is the Airtac PBJ Adjustable Pen-Type Cylinder PBJ10X80-30 the Right Cylinder?
When sizing this 10mm bore, note the 12mm bore offers 56.5N push at 0.5MPa if you need more force, while the 10mm bore itself provides 39.3N. Remember that only the retract end is adjustable; the extend position is fixed. After setting your 50-80mm range, re-tighten the M4x0.7 lock nut to prevent vibration drift. Confirm your ordering essentials: bore, stroke, window, magnet (none here), and mount.
Quick checklist
- ✓ Need to fine-tune the end position on site
- ✓ Retract end sits within 50–80 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 PBJ10X80-30 FAQ
The effective stroke range is 50-80mm (nominal 80mm minus up to 30mm). Force is identical to a standard PB cylinder: 39.3N push and 33N pull at 0.5MPa, or 55N push and 46.2N pull at the 0.7MPa maximum.
A rear M4x0.7 adjuster screw shortens only the retract end of the stroke; the extend end is fixed. You must re-tighten the lock nut after setting your desired length to prevent vibration drift.
