Airtac PBJ Adjustable Pen-Type Cylinder PBJ10X100-40S
The AirTAC Airtac PBJ Adjustable Pen-Type Cylinder PBJ10X100-40S 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 40mm fine-adjustable window — settable from 60 to 100mm, so you set the end position without changing hardware.

About the Airtac PBJ Adjustable Pen-Type Cylinder PBJ10X100-40S
The AirTAC PBJ10X100-40S 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 and lock nut shorten the retract end, giving an effective stroke range of 60-100 mm. The extend end remains fixed. Force is identical to a standard PB cylinder, delivering about 39.3 N of push at 0.5 MPa. The M5x0.8 air port and Ø4 mm stainless steel rod keep the body slim for tight jigs.
The built-in magnet works with reed or electronic switches. Because the rod is only Ø4 mm, you should add an external guide or linear bearing for off-axis loads over this long stroke. The fixed TPU bumper decelerates motion only in the final few millimeters. For higher speeds with real tooling mass, meter-out the exhaust or add an external shock absorber.

| Bore size | Ø10 mm |
| Rod diameter | Ø4 mm |
| Nominal stroke | 100 mm |
| Adjustable window | 40 mm (60–100 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 PBJ10X100-40S Is Used
Changeover Fixtures
Dial in the exact retract distance from 60 to 100 mm during product changeovers without machining new stop blocks or ordering alternate cylinders.
Trial Stops
Set precise end positions for prototype testing and validation jigs, locking the M4x0.7 adjuster nut firmly once the ideal travel is found.
Variable Depth Insertion
Tune the extend-and-return depth for light insertion tasks, using the 39.3 N push at 0.5 MPa to seat parts without overtravel.
Is the Airtac PBJ Adjustable Pen-Type Cylinder PBJ10X100-40S the Right Cylinder?
This 10 mm bore provides 39.3 N push and 33 N pull at 0.5 MPa. If you need less force, there is no smaller PBJ bore, so consider a different series entirely. If your fixture requires more power, step up to the 12 mm bore, which offers 56.5 N push at 0.5 MPa. Remember that only the retract position is field-adjustable; the extend end is fixed. Always re-tighten the lock nut after setting the 60-100 mm range to prevent vibration drift. Confirm your ordering essentials: bore, stroke, window, magnet (S), and mount.
Quick checklist
- ✓ Need to fine-tune the end position on site
- ✓ Retract end sits within 60–100 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 PBJ10X100-40S FAQ
At 0.5 MPa, push force is 39.3 N and pull force is 33 N. At the maximum 0.7 MPa operating pressure, push is 55 N and pull is 46.2 N. The nominal stroke is 100 mm, and the rear adjuster provides an effective stroke range of 60-100 mm by shortening the retract end only.
A rear M4x0.7 screw shortens the retract end, while the extend end remains fixed. You must re-tighten the lock nut after setting your desired length to prevent vibration drift. The -S suffix indicates a built-in piston magnet compatible with reed or electronic switches for position sensing.
