Airtac PBJ Adjustable Pen-Type Cylinder PBJ10X100-20
The AirTAC Airtac PBJ Adjustable Pen-Type Cylinder PBJ10X100-20 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 20mm fine-adjustable window — settable from 80 to 100mm, so you set the end position without changing hardware.

About the Airtac PBJ Adjustable Pen-Type Cylinder PBJ10X100-20
The AirTAC PBJ10X100-20 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) shortens the retract end, giving an effective stroke range of 80-100 mm. You can tune the length directly on the machine without ordering new hardware. The extend end remains fixed. Output force equals a standard PB cylinder of the same bore, delivering 39.3 N push at 0.5 MPa.
Built with a SUS304 stainless barrel and rod, this slim body saves space in tight jigs. It features a fixed TPU bumper at each end and uses an M5x0.8 air port. Because the rod is only 4 mm thick, use an external guide for off-axis loads over this long stroke. Plan for a safe working load of about 24 N, which is roughly 60 percent of the 0.5 MPa push rating.

| Bore size | Ø10 mm |
| Rod diameter | Ø4 mm |
| Nominal stroke | 100 mm |
| Adjustable window | 20 mm (80–100 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.

Is the Airtac PBJ Adjustable Pen-Type Cylinder PBJ10X100-20 the Right Cylinder?
This 10 mm bore provides 39.3 N push at 0.5 MPa. If you need less force, the smaller bore options offer lower thrust; if your fixture requires more power, step up to the 12 mm bore for 56.5 N. Remember that only the retract position is adjustable on this unit. You must re-tighten the lock nut after setting your 80-100 mm range to prevent vibration drift. Confirm your ordering essentials: bore, stroke, window, mount, and magnet. This specific model ships without a sensor magnet.
Quick checklist
- ✓ Need to fine-tune the end position on site
- ✓ Retract end sits within 80–100 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 PBJ10X100-20 FAQ
The effective stroke range is 80-100 mm. At 0.5 MPa it provides 39.3 N push and 33 N pull. At the maximum 0.7 MPa operating pressure, it provides 55 N push and 46.2 N pull.
A rear screw shortens only the retract end of the stroke; the extend end is fixed. After setting your desired position, you must re-tighten the lock nut to prevent vibration drift.
