Airtac PBJ Adjustable Pen-Type Cylinder PBJ10X100-75
The AirTAC Airtac PBJ Adjustable Pen-Type Cylinder PBJ10X100-75 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 100mm stroke with a 75mm fine-adjustable window — settable from 25 to 100mm, so you set the end position without changing hardware.

About the Airtac PBJ Adjustable Pen-Type Cylinder PBJ10X100-75
The AirTAC PBJ10X100-75 is a double-acting, single-rod pen-size mini cylinder with a 75mm adjustable-stroke window. A rear adjuster screw and lock nut shorten the retract end, giving an effective stroke range of 25-100mm. The extend end is fixed. Output force matches a standard PB cylinder of the same bore, delivering 39.3N push and 33N pull at 0.5MPa.
The slim SUS304 stainless body saves space on tight jigs. The M5x0.8 air port is fixed by the 10mm bore. A fixed TPU bumper decelerates the last few mm at each end. Because the rod is a slender 4mm, add an external guide for off-axis loads over this long 100mm stroke.

|---|---|
| Series | PBJ JIS pen-size adjustable-stroke cylinder |
| Bore size | Ø10 mm |
| Rod diameter | Ø4 mm |
| Nominal stroke | 100 mm |
| Adjustable window | 75 mm (25–100 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 PBJ10X100-75 Is Used
Changeover Fixtures
Dial in the retract length from 25 to 100mm during product changeovers without machining new stops.
Trial Insertion Stops
Fine-tune insertion depth on test jigs by turning the rear screw, then lock the nut for the run.
Variable Depth Press
Set exact retract positions for pressing varied pins on a single compact pen-size body.
Is the Airtac PBJ Adjustable Pen-Type Cylinder PBJ10X100-75 the Right Cylinder?
Size both ways against the 10mm bore: dropping to a smaller bore lowers force, while stepping up to a 12mm bore gives 56.5N push at 0.5MPa. This 10mm bore provides 39.3N push at 0.5MPa. Good practice loads a cylinder to 60-70% of theoretical force, so plan for about 24N of real work at 0.5MPa. Vertically, it lifts about 2kg with a 2:1 margin.
Only the retract end is adjustable; the extend position is fixed. Re-tighten the lock nut after setting to stop vibration drift. Confirm ordering essentials: 10mm bore, 100mm nominal stroke, 75mm window, no magnet, and any LB or FA mount.
Quick checklist
- ✓ Need to fine-tune the end position on site
- ✓ Retract end sits within 25–100 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 PBJ10X100-75 FAQ
Force equals a standard PB 10mm bore: 39.3N push and 33N pull at 0.5MPa, or 55N push and 46.2N pull at the 0.7MPa maximum. The 75mm window gives an effective stroke range of 25-100mm.
The M4x0.7 rear screw shortens the retract end only; the extend end is fixed. Re-tighten the lock nut after setting to prevent vibration drift. A plain cylinder does not hold position on air loss, so use an external stop for a fail-safe hold.
