Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X150-30S
The AirTAC Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X150-30S 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 30mm fine-adjustable window — settable from 120 to 150mm, so you set the end position without changing hardware.

About the Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X150-30S
The AirTAC PBJ16X150-30S is a double-acting, single-rod pen-size mini cylinder with a 30mm adjustable window. A rear M5x0.8 adjuster screw and lock nut shorten the retract end, giving an effective stroke range of 120-150mm. The extend end remains fixed. Output force matches a standard PB body, delivering 100.5N push and 90.7N pull at 0.5MPa without any penalty for adjusting the length.
The slim SUS304 stainless body saves space in tight jigs. It features a fixed TPU bumper at each end and a built-in piston magnet for reed or electronic switches. For real-world work, plan for a safe working load of about 60N (roughly 60% of the 0.5MPa push figure) to account for seal friction and smooth travel.
Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X150-30S Technical Specifications
| Model | Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X150-30S |
|---|---|
| Series | PBJ JIS pen-size adjustable-stroke cylinder |
| Bore size | Ø16 mm |
| Rod diameter | Ø5 mm |
| Nominal stroke | 150 mm |
| Adjustable window | 30 mm (120–150 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) |
| Max standard stroke | Up to 200 mm |
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 PBJ16X150-30S Is Used
Variable-Depth Insertion
Dial in exact press depths for different parts on the same line. Set the retract stop from 120 to 150mm to swap profiles quickly without ordering new hardware.
Changeover Fixtures
Adapt test stands to new product lengths rapidly. The rear screw lets operators tune the back position on the machine, cutting changeover time during production shifts.
Trial Stop Positioning
Find the optimal end-of-stroke location during prototype runs. Lock the nut once the perfect 120-150mm retract distance is found for repeatable cycling.
Is the Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X150-30S the Right Cylinder?
This 16mm bore provides 100.5N push at 0.5MPa. Stepping down to a 12mm bore drops push to 56.5N, while no larger pen-size option exists in this series. Remember that only the retract position is tunable; 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, 30mm window, S magnet, and mounting choice. The M5x0.8 air port and M10x1.0 rod-end thread are fixed by the bore. Over this 150mm stroke, the Ø5mm rod is slender—add an external guide or linear bearing for off-axis loads to avoid side load damage.
Quick checklist
- ✓ Need to fine-tune the end position on site
- ✓ Retract end sits within 120–150 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 PBJ16X150-30S FAQ
It delivers 100.5N push and 90.7N pull at 0.5MPa, and 140.7N push and 126.9N pull at the 0.7MPa maximum. The nominal stroke is 150mm, and the 30mm adjustable window gives an effective stroke range of 120-150mm.
A rear M5x0.8 screw shortens the retract end only; the extend end is fixed. You must re-tighten the lock nut after setting to stop vibration drift. The S suffix means a built-in piston magnet is present for position sensing with reed or electronic switches.
