Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X80-30
The AirTAC Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X80-30 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 PBJ16X80-30
The AirTAC PBJ16X80-30 is a double-acting, single-rod pen-size mini cylinder with a 30mm adjustable window. A rear adjuster screw and lock nut shorten the retract end, giving an effective stroke range of 50-80mm. Tuning the length on the machine avoids reordering hardware for changeovers. The extend end remains fixed. Output matches a standard PB of this 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. The M5x0.8 air port and M10x1.0 rod-end thread keep fixtures compact. The thin Ø5mm rod handles coaxial thrust; over long strokes add an external guide to prevent side-load wear. The bumper only decelerates the last few millimetres, so at high speeds with real tooling mass, meter-out the exhaust or add a shock absorber.

| Model | Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X80-30 |
|---|---|
| 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 PBJ16X80-30 Is Used
Changeover Fixtures
Dial in the retract stop from 50 to 80mm during product changeovers without machining new hard stops.
Trial Insertion Stops
Fine-tune the depth of a press fit in test jigs, locking the nut once the perfect position is found.
Variable Lift Stations
Lift roughly 5.1kg vertically at 0.5MPa, adjusting the upstroke distance to clear varying part heights.
Is the Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X80-30 the Right Cylinder?
Size this 16mm bore against its neighbours: a 12mm bore gives 56.5N push at 0.5MPa, while a larger 20mm bore offers higher force. This 16mm model provides 100.5N push at 0.5MPa. Plan for a safe working load of roughly 60N, which is about 60% of the theoretical force, to account for seal friction. For vertical lifts, expect to raise about 5.1kg with a 2:1 safety margin.
Remember the rear screw only adjusts the retract position; the extend end is fixed. Re-tighten the lock nut after setting to prevent vibration drift. Confirm your ordering essentials: 16mm bore, 80mm nominal stroke, 30mm window, no magnet, and mounting choice.
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 PBJ16X80-30 FAQ
It delivers 100.5N push and 90.7N pull at 0.5MPa, and 140.7N push and 126.9N pull at the 0.7MPa maximum. The nominal stroke is 80mm with a 30mm window, yielding an effective range of 50-80mm.
The rear screw shortens the retract end only; the extend end is fixed. You set the stroke from 50 to 80mm and then re-tighten the lock nut to prevent vibration drift. The cylinder does not hold position on air loss without an external stop.
