Airtac PBJ Adjustable Pen-Type Cylinder PBJ10X100-30S
The AirTAC Airtac PBJ Adjustable Pen-Type Cylinder PBJ10X100-30S 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 30mm fine-adjustable window — settable from 70 to 100mm, so you set the end position without changing hardware.

About the Airtac PBJ Adjustable Pen-Type Cylinder PBJ10X100-30S
The AirTAC PBJ10X100-30S is a double-acting, single-rod pen-size mini cylinder with a 10 mm bore and a 100 mm nominal stroke. A rear adjuster screw (M4x0.7 thread) with a lock nut lets you trim the retract end, providing an effective stroke range of 70-100 mm. You can dial in the exact length on the machine without ordering new hardware. Output force stays identical to a standard PB body, delivering about 39.3 N push at 0.5 MPa.
The slim SUS304 stainless body saves space in tight jigs, and the M5x0.8 air port matches the bore. Because the rod is only Ø4 mm, you should add an external guide or linear bearing over this long 100 mm stroke to prevent side-load damage. The -S suffix means a built-in piston magnet is fitted for position sensing with reed or electronic switches. A fixed TPU bumper decelerates the last few mm of travel.

| Series | PBJ JIS pen-size adjustable-stroke cylinder |
| Bore size | Ø10 mm |
| Rod diameter | Ø4 mm |
| Nominal stroke | 100 mm |
| Adjustable window | 30 mm (70–100 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 PBJ10X100-30S Is Used
Variable-Depth Insertion
Tune the retract stop on the fly for different part heights during press-fit or insertion tasks without swapping out the entire actuator.
Changeover Fixtures
Speed up product changeovers on packaging lines by simply turning the rear screw to adjust the effective stroke to the new format.
Trial Stop Positioning
Use the 70-100 mm range to test and set exact end-of-stroke positions during prototype tooling setup before finalizing hard stops.
Is the Airtac PBJ Adjustable Pen-Type Cylinder PBJ10X100-30S the Right Cylinder?
Select this 10 mm bore actuator when you need field-tunable positioning between 70 and 100 mm. If your task requires less push, moving down is not an option within this series, but sizing up to a 12 mm bore raises the 0.5 MPa push force to 56.5 N. Remember that only the back position is adjustable; the extend end remains fixed. After setting your desired length, re-tighten the lock nut firmly, as vibration can drift an unlocked screw.
Confirm your ordering essentials: 10 mm bore, 100 mm nominal stroke, 30 mm window, built-in magnet (S), and your preferred mounting style. For practical sizing, plan for a safe working load of about 24 N (roughly 60% of the 39.3 N theoretical push at 0.5 MPa) to account for seal friction. This equates to lifting about 2 kg vertically with a sane 2:1 margin.
Quick checklist
- ✓ Need to fine-tune the end position on site
- ✓ Retract end sits within 70–100 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 PBJ10X100-30S FAQ
The effective stroke range is 70-100 mm. At 0.5 MPa, the push force is 39.3 N and the pull force is 33 N. At the maximum operating pressure of 0.7 MPa, the push force is 55 N and the pull force is 46.2 N. Adjusting the stroke does not change these force figures.
A rear screw shortens the retract end only; the extend end is fixed. You must re-tighten the lock nut after setting to prevent vibration drift. A plain PB-type cylinder does not hold its load on air loss—the piston drifts, and the fixed TPU bumper only decelerates near stroke end. Use an external rod lock for fail-safe holding.
