Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X90-30
The AirTAC Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X90-30 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 90mm stroke with a 30mm fine-adjustable window — settable from 60 to 90mm, so you set the end position without changing hardware.

About the Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X90-30
The AirTAC PBJ16X90-30 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 60-90mm. You can tune the travel on the machine during commissioning without ordering new hardware. The extend end remains fixed.
Output force matches the standard PB body exactly, free of any penalty from the adjuster. It provides 100.5N push and 90.7N pull at 0.5MPa. The bore is 16mm, the air port is M5x0.8, and the rod-end thread is M10x1.0. A fixed TPU bumper decelerates the last few mm of travel. Plan for a safe working load of about 60N, which is roughly 60% of the 0.5MPa push rating, to account for seal friction and smooth travel.

| Series | PBJ JIS pen-size adjustable-stroke cylinder |
| Bore size | Ø16 mm |
| Rod diameter | Ø5 mm |
| Nominal stroke | 90 mm |
| Adjustable window | 30 mm (60–90 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 PBJ16X90-30 Is Used
Changeover Fixtures
Switch product families on a line by dialing the retract stroke from 60 to 90mm instead of rebuilding the jig.
Trial Stops
Set provisional end positions during prototyping to find the exact insertion depth before locking the nut.
Variable Insertion
Press parts to different depths on the same tool by adjusting the rear screw within the 30mm window.
Is the Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X90-30 the Right Cylinder?
This 16mm bore yields 100.5N push at 0.5MPa. Stepping down to a 12mm bore drops the push force to 56.5N, while moving up to a larger body increases it further. Pick the 16mm size if the 12mm capacity is insufficient. Remember that only the retract position is settable; the extend end is fixed. After dialing in the 60-90mm range, re-tighten the lock nut so vibration cannot drift the M5x0.8 adjuster screw. Confirm your ordering essentials: 16mm bore, 90mm nominal stroke, 30mm window, no magnet, and your mounting choice.
The Ø5mm rod is built for coaxial thrust. Over this 90mm stroke or with off-axis loads, add an external guide or linear bearing to prevent side load damage. This plain cylinder does not hold position on air loss; the piston drifts. Use an external stop or rod lock for a fail-safe hold.
Quick checklist
- ✓ Need to fine-tune the end position on site
- ✓ Retract end sits within 60–90 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 PBJ16X90-30 FAQ
The effective stroke range is 60-90mm. At 0.5MPa it delivers 100.5N push and 90.7N pull. At the 0.7MPa maximum, it provides 140.7N push and 126.9N pull.
A rear M5x0.8 screw shortens the retract end up to 30mm, while the extend end is fixed. You must re-tighten the lock nut after setting to prevent vibration drift.
