The AirTAC Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X75-75 is a double-acting pen-size mini cylinder with a rear adjuster screw that shortens the retract end of the stroke. On a Ø16mm bore it gives a nominal 75mm stroke with a 75mm fine-adjustable window, so you set the end position without changing hardware.
The AirTAC PBJ16X75-75 is a JIS pen-size double-acting mini cylinder with a 75mm adjustable-stroke window. A rear adjuster screw and lock nut shorten the retract end, giving an effective stroke range of 0-75mm. You can tune the exact length on the machine without ordering new hardware. The extend end remains fixed.
Force is identical to a standard PB cylinder of the same bore, delivering 100.5N push and 90.7N pull at 0.5MPa. The slim SUS304 stainless body includes a fixed TPU bumper at each end and uses an M5x0.8 port. Plan for a safe working load of about 60N, which allows for seal friction and smooth travel.
| Model | Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X75-75 |
|---|---|
| Series | PBJ JIS pen-size adjustable-stroke cylinder |
| Bore size | Ø16 mm |
| Rod diameter | Ø5 mm |
| Nominal stroke | 75 mm |
| Adjustable window | 75 mm (0–75 mm) |
| Adjuster thread | M5×0.8 |
| 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 200 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.
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 100.5 N | 90.7 N |
| 0.7 MPa (max) | 140.7 N | 126.9 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).
Rapidly tune the retract length for different part heights on a single jig without swapping out the entire cylinder.
Dial in the exact end-of-stroke position during prototype testing to find the optimal travel distance.
Adjust the retraction depth on the fly for pressing or inserting operations with varying material thicknesses.
This 16mm bore provides 100.5N push at 0.5MPa. If you need less force, the 12mm bore offers 56.5N push; if you need more, the 16mm bore is the largest available in this pen-size series. Remember that only the retract end is adjustable, so verify your extend position is fixed before layout.
After setting your stroke, re-tighten the lock nut to prevent vibration drift. Confirm your ordering essentials: 16mm bore, 75mm stroke, 75mm window, and your required LB or FA mount. This unit has no magnet.
Quick checklist
The effective stroke range is 0-75mm. At 0.5MPa, push force is 100.5N and pull force is 90.7N. At the maximum 0.7MPa operating pressure, push is 140.7N and pull is 126.9N.
A rear M5x0.8 adjuster 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.
