Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X75-50
The AirTAC Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X75-50 is a double-acting, double-rod pen-size mini cylinder whose rear rod carries a stroke adjuster. On a Ø16mm bore it gives a nominal 75mm stroke with a 50mm fine-adjustable window — settable from 25 to 75mm, so you set the end position without changing hardware.

About the Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X75-50
The AirTAC PBJ16X75-50 is a double-acting, double-rod pen-size mini cylinder featuring a 50 mm adjustable stroke window. A rear adjuster screw and lock nut shorten the retract end, giving an effective stroke range of 25-75 mm. This on-machine tuning lets you dial in the exact return position during commissioning without swapping hardware. The extend end remains fixed.
The Ø5 mm piston rod and barrel are SUS304 stainless, and a fixed TPU bumper cushions each end. The air port is M5x0.8, and the rod-end thread is M10x1.0.

PBJ is a double-rod cylinder: the rear rod carries the stroke adjuster, which sets the stroke end within the adjustable window. Confirm the set position against the product label before installation.
Theoretical Output Force (Ø16mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 90.7 N | 90.7 N |
| 0.7 MPa (max) | 126.9 N | 126.9 N |
The rear rod passes through the rear cover, so both piston faces lose rod area: push is shown at the annular-area value (conservative), lower than a single-rod PB push of the same bore. Size with a friction margin.

Where the Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X75-50 Is Used
Changeover Fixtures
Dial in the retract length from 25 to 75 mm during product changeovers to hit different stop depths without machining new pins.
Trial Insertion Stops
Test variable insertion depths on delicate assemblies by turning the rear screw, then lock the nut for repeatable cycles.
Is the Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X75-50 the Right Cylinder?
Remember that only the retract end is adjustable, so verify your extend length is acceptable before ordering.
After setting your 25-75 mm effective stroke, re-tighten the lock nut on the M5x0.8 adjuster thread to prevent vibration drift. Confirm your ordering essentials: 16 mm bore, 75 mm nominal stroke, 50 mm window, no magnet, and your preferred LB or FA mount.
Quick checklist
- ✓ Need to fine-tune the end position on site
- ✓ Retract end sits within 25–75 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 Double rod: the rear rod carries the stroke adjuster.
- 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 PBJ16X75-50 FAQ
The effective stroke range is 25-75 mm.
A rear screw shortens the retract end while the extend end stays fixed. After setting the length, re-tighten the lock nut to prevent drift. A plain cylinder does not hold position on air loss; the piston drifts and the fixed TPU bumper only decelerates near the stroke end, so use an external rod lock for fail-safe holding.
