The AirTAC Airtac PBJ Adjustable Pen-Type Cylinder PBJ10X160-20S 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.
The AirTAC PBJ10X160-20S is a double-acting, single-rod pen-size mini cylinder with a 20mm adjustable-stroke window. A rear screw and lock nut shorten the retract end, giving an effective stroke range of 140-160mm. The extend end remains fixed. Output force equals a standard PB cylinder of the same bore, delivering 39.3N push at 0.5MPa. This 160mm stroke exceeds the 100mm max standard for this 10mm bore, making it a made-to-order item.
The slim SUS304 stainless body saves space in tight jigs. A fixed TPU bumper decelerates the piston at both ends. The -S denotes a built-in piston magnet for reed or electronic switches. The Ø4mm rod is built for coaxial thrust; over long 160mm strokes, add an external guide to prevent side-load wear. Air port is M5x0.8.

| 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 |

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.
| 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.

Fixed body — no separate back-cover code. Mounting accessories: LB, FA. Related PB-family variants: PB (fixed stroke), PBD (double rod), PBR (front-mount).
Dial in the retract stop from 140 to 160mm during product changeovers without machining new hard stops.
Fine-tune the return position on test rigs to find the exact travel before committing to a fixed length.
Adjust the back position for varying part heights in light-duty insertion or pressing jigs.
For sizing, the neighbouring 12mm bore gives 56.5N push, while the smaller 8mm bore gives less force. This 10mm bore yields 39.3N push at 0.5MPa. Good practice loads a cylinder to 60-70% of theoretical force, so plan for a safe working load of about 24N. For vertical lifts, expect to lift about 2kg with a 2:1 safety margin. Remember only the retract end is adjustable; re-tighten the lock nut after setting to prevent vibration drift. Confirm ordering essentials: 10mm bore, 160mm stroke, 20mm window, S magnet, and mounting.
Quick checklist
At 0.5MPa it gives 39.3N push and 33N pull. At the 0.7MPa maximum it gives 55N push and 46.2N pull. The effective adjustable stroke range is 140-160mm (nominal 160mm minus up to 20mm).
The M4x0.7 rear screw shortens only the retract end; the extend end is fixed. Re-tighten the lock nut after setting to stop vibration drift. The -S built-in piston magnet works with reed or electronic switches.
