Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X150-50
The AirTAC Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X150-50 is a double-acting pen-size mini cylinder with a rear adjuster screw that shortens the retract end of the stroke. 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 PBJ16X150-50
The AirTAC PBJ16X150-50 is a double-acting, single-rod pen-size mini cylinder with a 50mm adjustable stroke window. A rear adjuster screw shortens the retract end, giving an effective stroke range of 100-150mm. The extend end remains fixed. Output force equals a standard PB cylinder of the same bore, delivering 100.5N push and 90.7N pull at 0.5MPa.
The slim body features a SUS304 stainless barrel and a fixed TPU bumper at each end. The M5x0.8 air port and M10x1.0 rod-end thread match the 16mm bore standard. For vertical lifting, plan for about 5.1kg of real work mass with a 2:1 safety margin at 0.5MPa. The Ø5mm rod is built for coaxial thrust, so over this 150mm length add an external guide to prevent side-load wear.

| Rod diameter | Ø5 mm |
| Nominal stroke | 150 mm |
| Adjustable window | 50 mm (100–150 mm) |
| Adjuster thread | M5×0.8 |
| Port size | M5×0.8 |
|---|---|
| Operating pressure | 0.15 – 0.7 MPa |
| Proof pressure | 1.2 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 50 – 800 mm/s |
| Cushion | Elastic bumper (both ends) |

The adjuster shortens only the retract end; the extend end is fixed. Force is unchanged from the standard PB double-acting cylinder. Confirm the set position against the product label before installation.
Theoretical Output Force (Ø16mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 100.5 N | 90.7 N |
| 0.7 MPa (max) | 140.7 N | 126.9 N |
Adjusting the stroke does not change output force — these are the same values as the standard PB double-acting cylinder of the same bore. Size with a friction margin.

Where the Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X150-50 Is Used
Variable-Depth Insertion
Dial in exact press-in depths for different product variants on the same jig using the 100-150mm effective range.
Changeover Fixtures
Quickly reset the retract length for new part heights without disassembling the cylinder or ordering new hardware.
Trial Stroke Stops
Fine-tune end positions during machine commissioning to find the exact travel before locking the nut.
Is the Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X150-50 the Right Cylinder?
To size correctly, compare this 16mm bore against its neighbours. Stepping down to a 12mm bore drops the 0.5MPa push force to 56.5N, whereas this 16mm unit provides 100.5N. If you need the maximum 140.7N push at 0.7MPa, this 16mm bore is the largest available in the series. Remember that only the retract position is field-settable; the extend end is fixed. Always re-tighten the lock nut after tuning the screw to prevent vibration drift. Confirm your ordering essentials: 16mm bore, 150mm nominal stroke, 50mm window, and any mount accessories.
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 The adjuster shortens the retract end only.
- 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 PBJ16X150-50 FAQ
The effective stroke range is 100-150mm. At 0.5MPa it provides 100.5N push and 90.7N pull. At the maximum 0.7MPa operating pressure, it provides 140.7N push and 126.9N pull.
The rear screw shortens the retract end only; the extend end is fixed. You must re-tighten the lock nut after setting to prevent vibration drift. A plain cylinder does not hold position on air loss, so use an external stop for fail-safe load holding.
