Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X55-10S
The AirTAC Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X55-10S 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 55mm stroke with a 10mm fine-adjustable window — settable from 45 to 55mm, so you set the end position without changing hardware.

About the Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X55-10S
The AirTAC PBJ16X55-10S is a double-acting, double-rod pen-size mini cylinder featuring a 10mm adjustable stroke window. A rear M5x0.8 adjuster screw shortens the retract end, giving an effective stroke range of 45 to 55 mm. The extend end remains fixed. The -S suffix means a built-in piston magnet for electronic or reed switch sensing.
This 16mm bore actuator uses an M5x0.8 air port and an M10x1.0 rod-end thread. The slim SUS304 stainless body includes a fixed TPU bumper at each end to decelerate motion.

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 PBJ16X55-10S Is Used
Changeover Fixtures
Quickly tune the 45-55mm retract length on the machine for different part heights without swapping hardware.
Variable-Depth Insertion
Dial in the exact press depth for delicate pins or plugs, using the rear screw to fine-tune the end position.
Trial Stroke Stops
Test clamping positions safely by shortening the stroke during prototyping, then extending it to the final 55mm.
Is the Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X55-10S the Right Cylinder?
Choose the larger bore if your payload exceeds 60 N of real work. Remember that only the retract position is field-settable; the extend stop is fixed. Always re-tighten the lock nut after tuning to prevent vibration drift.
Confirm your ordering essentials: 16mm bore, 55mm nominal stroke, 10mm window, S magnet, and any LB or FA mount. The Ø5mm rod handles coaxial thrust well, but add an external linear guide for off-axis loads to prevent rod bending.
Quick checklist
- ✓ Need to fine-tune the end position on site
- ✓ Retract end sits within 45–55 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 PBJ16X55-10S FAQ
The effective stroke range is 45 to 55 mm. The 16mm bore uses an M5x0.8 port.
A rear M5x0.8 screw shortens only the retract end of the stroke; the extend end is fixed. You must re-tighten the lock nut after setting to prevent vibration drift. The cylinder does not hold position on air loss, so use an external stop for fail-safe load holding.
