Airtac PBJ Adjustable Pen-Type Cylinder PBJ10X150-30S
The AirTAC Airtac PBJ Adjustable Pen-Type Cylinder PBJ10X150-30S is a double-acting pen-size mini cylinder with a rear adjuster screw that shortens the retract end of the stroke. On a Ø10mm 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 PBJ10X150-30S
The AirTAC PBJ10X150-30S is a double-acting, single-rod pen-size mini cylinder with a 30mm adjustable stroke window. A rear adjuster screw and lock nut shorten the retract end, giving an effective stroke range of 120 to 150mm. The extend end remains fixed. Output force matches a standard PB body of the same bore, delivering about 39.3N push at 0.5MPa. This 150mm length is a non-standard, made-to-order stroke for the 10mm bore.
The slim SUS304 stainless body saves space on tight jigs. It uses an M5x0.8 port and an M8x1.0 rod-end thread. A fixed TPU bumper cushions the last few millimeters of travel. The built-in piston magnet works with reed or electronic switches. Because the rod is only Ø4mm, add an external guide for off-axis loads over this long stroke.

| Nominal stroke | 150 mm |
| Adjustable window | 30 mm (120–150 mm) |
| Adjuster thread | M4×0.7 |
| 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 (Ø10mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 39.3 N | 33.0 N |
| 0.7 MPa (max) | 55.0 N | 46.2 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 PBJ10X150-30S Is Used
Changeover Fixtures
Dial in the exact retract stop during machine changeover without machining new spacers or ordering replacement cylinders.
Trial Insertion Stops
Fine-tune insertion depth on test assemblies. Back out the adjuster screw to find the perfect seating position.
Variable Depth Probes
Set precise sensing heights across different product variants. The 120-150mm range handles tall test profiles.
Is the Airtac PBJ Adjustable Pen-Type Cylinder PBJ10X150-30S the Right Cylinder?
Plan for a safe working load of roughly 24N, which is about 60% of the 39.3N theoretical push at 0.5MPa. For vertical lifts, expect to raise about 2kg with a 2:1 safety margin. If you need less force, dropping to a smaller bore is an option; if your fixture requires more thrust, stepping up to the 12mm bore gives 56.5N push at 0.5MPa.
Remember that only the retract position is field-adjustable. Set your distance, then re-tighten the lock nut on the M4x0.7 adjuster thread so vibration does not drift the screw. Confirm your ordering essentials: 10mm bore, 150mm nominal stroke, 30mm window, S magnet, and mounting.
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 PBJ10X150-30S FAQ
The effective stroke range is 120 to 150mm. Force equals a standard PB 10mm bore: 39.3N push and 33N pull at 0.5MPa. At the maximum 0.7MPa operating pressure, it provides 55N push and 46.2N pull.
The rear M4x0.7 screw shortens only the retract end; the extend end is fixed. Re-tighten the lock nut after setting to prevent drift. A plain cylinder does not hold position on air loss, so use an external rod lock for fail-safe holding.
