Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X80-30S
The AirTAC Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X80-30S 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 80mm stroke with a 30mm fine-adjustable window — settable from 50 to 80mm, so you set the end position without changing hardware.

About the Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X80-30S
The AirTAC PBJ16X80-30S is a double-acting, single-rod pen-size mini cylinder with a 30mm adjustable stroke window. A rear M5x0.8 adjuster screw shortens the retract end, giving an effective stroke range of 50-80mm. The extend end remains fixed. Output force equals a standard PB of this bore, delivering 100.5N push at 0.5MPa with no penalty for the adjustment feature.
The slim body uses a SUS304 stainless rod and barrel, fitting tight jigs and light end-of-arm tooling. A fixed TPU bumper cushions each end. The -S suffix adds a built-in piston magnet for position sensing. For real work at 0.5MPa, plan for a safe working load of about 60N (roughly 60% of the theoretical force) to account for seal friction.

| Model | Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X80-30S |
|---|---|
| Series | PBJ JIS pen-size adjustable-stroke cylinder |
| Bore size | Ø16 mm |
| Rod diameter | Ø5 mm |
| Nominal stroke | 80 mm |
| Adjustable window | 30 mm (50–80 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.
Theoretical Output Force (Ø16mm)
| 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.

Where the Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X80-30S Is Used
Changeover Fixtures
Dial in the retract position from 50 to 80mm during product family changeovers without machining new stop collars or ordering alternate cylinders.
Trial Insertion Stops
Gradually tune the back position for variable-depth press fits, protecting delicate components during first-off prototype assembly.
Vertical Lift Jigs
Lifts about 5.1kg vertically with a 2:1 safety margin at 0.5MPa; adjust the retract to accommodate varying part heights without repositioning sensors.
Is the Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X80-30S the Right Cylinder?
This 16mm bore provides 100.5N push and 90.7N pull at 0.5MPa. Stepping down to a 12mm bore drops push to 56.5N, while a larger bore exceeds this frame size. The air port is M5x0.8 and the rod-end thread is M10x1.0. Remember that only the retract position is settable; the extend end is fixed. Always re-tighten the lock nut after tuning the stroke to prevent vibration drift.
When ordering, confirm the bore, 80mm nominal stroke, 30mm window, S magnet, and any LB or FA mounting hardware. The Ø5mm rod handles coaxial thrust; add an external linear guide for off-axis loads. Note that a plain cylinder drifts on air loss, so use an external stop for fail-safe holding.
Quick checklist
- ✓ Need to fine-tune the end position on site
- ✓ Retract end sits within 50–80 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 PBJ16X80-30S FAQ
The effective stroke range is 50-80mm. At 0.5MPa it gives 100.5N push and 90.7N pull. At the 0.7MPa maximum, it gives 140.7N push and 126.9N pull.
The rear M5x0.8 screw shortens the retract end only; the extend end is fixed. Re-tighten the lock nut after setting to prevent vibration drift. The built-in magnet works with AirTAC reed or electronic switches.
