About the Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X50-50
The AirTAC PBJ16X50-50 is a double-acting, double-rod pen-size mini cylinder with a 50mm adjustable window. A rear adjuster screw and lock nut shorten the retract end, giving an effective stroke range of 0-50mm. The extend end remains fixed.
The slim body features a SUS304 stainless rod and barrel, plus a fixed TPU bumper at each end. The M5x0.8 port and M10x1.0 rod-end thread keep installation simple.

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.

Variable-Depth Insertion
Tune the retract distance to control insertion depth for varying component lengths.
Is the Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X50-50 the Right Cylinder?
Remember that only the retract position is field-settable; the extend end is fixed. Always re-tighten the lock nut after tuning to prevent vibration drift.
Confirm your ordering essentials: 16mm bore, 50mm nominal stroke, 50mm adjuster window, and whether you need an LB or FA mount. This variant lacks a sensor magnet.
Quick checklist
- ✓ Need to fine-tune the end position on site
- ✓ Retract end sits within 0–50 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 PBJ16X50-50 FAQ
The effective stroke range is 0-50mm.
The M5x0.8 rear screw shortens only the retract end; the extend end is fixed. After setting your desired position, you must re-tighten the lock nut to prevent vibration drift.
