Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X150-50S
The AirTAC Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X150-50S 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 150mm stroke with a 50mm fine-adjustable window — settable from 100 to 150mm, so you set the end position without changing hardware.

About the Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X150-50S
The AirTAC PBJ16X150-50S is a double-acting, double-rod pen-size mini cylinder with a 50mm adjustable stroke window. A rear M5x0.8 adjuster screw and lock nut shorten the retract end, giving an effective stroke range of 100-150mm. The extend end remains fixed. The M5x0.8 air port and Ø5mm rod are paired with a fixed TPU bumper at each end.
This SUS304 stainless build includes a built-in piston magnet for reed or electronic switches. The slim body saves space in tight jigs. The thin Ø5mm rod handles coaxial thrust; over long strokes add an external guide to prevent side-load wear.

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 PBJ16X150-50S Is Used
Changeover Fixtures
Dial in the exact retract distance from 100 to 150mm during product changeovers without machining new stops or reordering cylinders.
Trial Insertion Stops
Fine-tune insertion depths on test jigs. The rear adjuster lets you tweak the back position while the forward extend stroke remains fixed.
Variable Depth Pressing
Set precise end-of-stroke positions for light pressing tasks. The built-in magnet works with reed or electronic switches for position confirmation.
Is the Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X150-50S the Right Cylinder?
Remember that only the retract position is tunable from 100 to 150mm, while the extend end is fixed. Always re-tighten the lock nut after setting the rear screw to prevent vibration drift. Confirm your ordering essentials: 16mm bore, 150mm nominal stroke, 50mm window, S magnet, and mounting accessories.
The fixed TPU bumper only decelerates the last few millimeters of travel. At mid-to-high speeds with real tooling mass, the bumper can bottom out, so meter-out the exhaust or fit an external shock absorber. A plain cylinder does not hold position on air loss; use an external stop for fail-safe load holding.
Quick checklist
- ✓ Need to fine-tune the end position on site
- ✓ Retract end sits within 100–150 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 PBJ16X150-50S FAQ
The nominal stroke is 150mm with a 50mm adjustable window, yielding an effective stroke range of 100-150mm. Force is unchanged from a standard PB cylinder of the same bore.
A rear M5x0.8 adjuster screw shortens the retract end of the stroke, while the extend end stays fixed. You set the effective length on the machine, then must re-tighten the lock nut to prevent vibration drift. The built-in S magnet is compatible with reed or electronic switches.
