Airtac PBJ Adjustable Pen-Type Cylinder PBJ10X160-20
The AirTAC Airtac PBJ Adjustable Pen-Type Cylinder PBJ10X160-20 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 160mm stroke with a 20mm fine-adjustable window — settable from 140 to 160mm, so you set the end position without changing hardware.

About the Airtac PBJ Adjustable Pen-Type Cylinder PBJ10X160-20
The AirTAC PBJ10X160-20 is a double-acting, single-rod pen-size mini cylinder with a 20mm adjustable stroke window. A rear adjuster screw shortens the retract end, giving an effective stroke range of 140-160mm. Force matches a standard PB of the same bore, delivering about 39.3N push at 0.5MPa.
This 160mm stroke exceeds the 100mm max standard for a 10mm bore, making it a non-standard or made-to-order item. The slim SUS304 stainless body uses an M5x0.8 port and a fixed TPU bumper. Because the rod is only 4mm thick, add an external guide for long strokes to prevent side-load deflection.

| Model | Airtac PBJ Adjustable Pen-Type Cylinder PBJ10X160-20 |
|---|---|
| Series | PBJ JIS pen-size adjustable-stroke cylinder |
| Bore size | Ø10 mm |
| Rod diameter | Ø4 mm |
| Nominal stroke | 160 mm |
| Adjustable window | 20 mm (140–160 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 PBJ10X160-20 Is Used
Changeover Fixtures
Dial in the exact 140-160mm retract position during product changeovers without machining new hard stops.
Trial Stops
Fine-tune the end position on test rigs to find the optimal depth before locking the nut down.
Variable Depth Insertion
Adjust insertion depth on the fly for different part heights using the rear screw, keeping force constant.
Is the Airtac PBJ Adjustable Pen-Type Cylinder PBJ10X160-20 the Right Cylinder?
Size both ways against the 10mm bore: dropping to a smaller bore lowers force, while stepping up to a 12mm bore yields 56.5N push at 0.5MPa. Keep this 39.3N model if that force is sufficient. Remember that only the retract end is adjustable; the extend end remains fixed. Always re-tighten the lock nut after setting the M4x0.7 adjuster to prevent vibration drift. Confirm ordering essentials: 10mm bore, 160mm stroke, 20mm window, no magnet, and mount choice.
Quick checklist
- ✓ Need to fine-tune the end position on site
- ✓ Retract end sits within 140–160 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 PBJ10X160-20 FAQ
Effective stroke is 140-160mm. At 0.5MPa it pushes 39.3N and pulls 33N. At the 0.7MPa maximum it pushes 55N and pulls 46.2N.
The rear M4x0.7 screw shortens only the retract end; the extend end is fixed. Re-tighten the lock nut after setting. A plain cylinder does not hold position on air loss, so add an external rod lock for fail-safe holding.
