Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X50-10S
The AirTAC Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X50-10S 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 50mm stroke with a 10mm fine-adjustable window — settable from 40 to 50mm, so you set the end position without changing hardware.

About the Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X50-10S
The AirTAC PBJ16X50-10S is a double-acting, double-rod pen-size mini cylinder with a 10mm adjustable stroke window. A rear adjuster screw shortens the retract end, giving an effective stroke range of 40-50mm. The extend end remains fixed.
The Ø16mm bore uses an M5x0.8 port and a Ø5mm stainless steel rod. This -S model includes a built-in piston magnet for reed or electronic switches. A fixed TPU bumper cushions each end. The thin rod handles coaxial thrust; use an external guide for side loads.

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.

Set precise insertion depth on light end-of-arm tooling using the 40-50mm range.
Is the Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X50-10S the Right Cylinder?
This makes the Ø16mm the right choice when the smaller bore lacks power. Remember that only the retract end is adjustable, so verify your extend position is fixed. Always re-tighten the lock nut after setting the stroke to prevent vibration drift.
Confirm ordering essentials: 16mm bore, 50mm nominal stroke, 10mm window, S magnet, and mounting option. The air port is M5x0.8. Max standard stroke for this bore is 200mm.
Quick checklist
- ✓ Need to fine-tune the end position on site
- ✓ Retract end sits within 40–50 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 PBJ16X50-10S FAQ
The effective stroke range is 40-50mm. At 0.5MPa, push is 100.5N and pull is 90.7N. At the 0.7MPa maximum, push is 140.7N and pull is 126.9N.
The rear screw shortens only the retract end; the extend end is fixed. Re-tighten the lock nut after setting to prevent drift. The -S model has a built-in magnet for reed or electronic switches.
