Airtac PBJ Adjustable Pen-Type Cylinder PBJ10X150-40S
The AirTAC Airtac PBJ Adjustable Pen-Type Cylinder PBJ10X150-40S 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 40mm fine-adjustable window — settable from 110 to 150mm, so you set the end position without changing hardware.

About the Airtac PBJ Adjustable Pen-Type Cylinder PBJ10X150-40S
The AirTAC PBJ10X150-40S is a double-acting, single-rod pen-size mini cylinder with a 40mm adjustable-stroke window. A rear M4x0.7 adjuster screw shortens the retract end, giving an effective stroke range of 110-150mm. The extend end remains fixed. Output force equals a standard PB of the same 10mm bore, delivering 39.3N push at 0.5MPa without any penalty for the adjustment feature.
This unit includes a built-in piston magnet for position sensing with reed or electronic switches. The slim SUS304 stainless body saves space in tight jigs. Note that the 150mm length exceeds the 100mm max standard stroke for this bore, making it a made-to-order item. The Ø4mm rod is built for coaxial thrust, so over long strokes add an external guide to prevent side-load wear.

|---|---|
| Series | PBJ JIS pen-size adjustable-stroke cylinder |
| Bore size | Ø10 mm |
| Rod diameter | Ø4 mm |
| Nominal stroke | 150 mm |
| Adjustable window | 40 mm (110–150 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) |
| Max standard stroke | Up to 100 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 (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 PBJ10X150-40S Is Used
Variable-Depth Insertion
Dial in precise insertion depths on the machine without swapping cylinders, using the 110-150mm range to test different seating heights.
Changeover Fixtures
Quickly retune the retract position for new product runs, cutting setup time while maintaining the 39.3N push force at 0.5MPa.
Trial Stop Positioning
Set exact back-stops during prototyping. The fixed TPU bumper absorbs end-impact while the rear screw fine-tunes the resting length.
Is the Airtac PBJ Adjustable Pen-Type Cylinder PBJ10X150-40S the Right Cylinder?
When sizing this 10mm bore, consider the neighbours: a smaller bore lacks the force here, while a 12mm bore yields 56.5N push at 0.5MPa if you need more thrust. For this model, plan for a safe working load of about 24N (roughly 60% of the 0.5MPa figure) to overcome seal friction and ensure smooth travel. This equates to lifting about 2kg vertically with a 2:1 safety margin.
Remember that only the back 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: 10mm bore, 150mm nominal stroke, 40mm window, S magnet, and any LB or FA mount. The air port is M5x0.8.
Quick checklist
- ✓ Need to fine-tune the end position on site
- ✓ Retract end sits within 110–150 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 PBJ10X150-40S FAQ
The effective stroke range is 110-150mm. At 0.5MPa the push force is 39.3N and pull is 33N. At the maximum 0.7MPa operating pressure, push is 55N and pull is 46.2N. These forces match a standard PB cylinder of the same bore.
The rear M4x0.7 screw shortens only the retract end; the extend end is fixed. You must re-tighten the lock nut after setting to prevent vibration drift. The S suffix means a built-in piston magnet is fitted, allowing you to use reed or electronic switches for position detection.
