Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X90-10S
The AirTAC Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X90-10S 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 90mm stroke with a 10mm fine-adjustable window — settable from 80 to 90mm, so you set the end position without changing hardware.

About the Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X90-10S
The AirTAC PBJ16X90-10S is a double-acting, single-rod pen-size mini cylinder with a 10mm adjustable window. A rear M5x0.8 adjuster screw and lock nut shorten the retract end, giving an effective stroke range of 80-90mm. The extend end remains fixed. Output force is identical to a standard PB body, delivering 100.5N push and 90.7N pull at 0.5MPa. The M5x0.8 air port and Ø5mm rod keep the unit compact.
Built with a SUS304 stainless barrel and rod, this slim cylinder saves space in tight jigs. It includes a fixed TPU bumper at each end and a built-in piston magnet for position sensing. For real-world sizing, plan for a safe working load of about 60N (roughly 60% of the 0.5MPa push figure) to account for seal friction. This equates to lifting about 5.1kg vertically with a sane 2:1 margin.

| Rod diameter | Ø5 mm |
| Nominal stroke | 90 mm |
| Adjustable window | 10 mm (80–90 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 PBJ16X90-10S Is Used
Variable-Depth Insertion
Dial in the 80-90mm retract stop to set precise insertion depths for pressing pins or plugs without machining new hard stops.
Changeover Fixtures
Quickly retune the back position when switching between product variants on a shared jig, saving hardware swap time.
Trial Stop Positioning
Use the rear M5x0.8 adjuster screw to find the optimal end-of-stroke location during prototype runs before locking the nut.
Is the Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X90-10S the Right Cylinder?
This 16mm bore provides 100.5N push at 0.5MPa. If you need less force, stepping down to a 12mm bore yields 56.5N push; stepping up is not applicable as 16mm is the largest PBJ bore. Remember that only the back position is tunable—the extend end is fixed. Always re-tighten the lock nut after setting your 80-90mm range to prevent vibration drift. Confirm your ordering essentials: 16mm bore, 90mm nominal stroke, 10mm window, S magnet, and any LB or FA mount.
The thin Ø5mm rod handles coaxial thrust well, but over long strokes or off-axis loads you should add an external guide or linear bearing to prevent side-load damage. A plain pneumatic body does not hold position on air loss, so install an external stop if fail-safe holding is required.
Quick checklist
- ✓ Need to fine-tune the end position on site
- ✓ Retract end sits within 80–90 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 PBJ16X90-10S FAQ
The effective stroke range is 80-90mm. At 0.5MPa it provides 100.5N push and 90.7N pull. At the maximum 0.7MPa operating pressure, it provides 140.7N push and 126.9N pull. Adjusting the stroke does not alter these forces.
A rear screw shortens the retract end only; the extend end is fixed. You must re-tighten the lock nut after setting your desired length to prevent vibration drift. The built-in S magnet works with AirTAC reed or electronic switches for position sensing.
