Airtac PBJ Adjustable Pen-Type Cylinder PBJ10X150-50S
The AirTAC Airtac PBJ Adjustable Pen-Type Cylinder PBJ10X150-50S 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 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 PBJ10X150-50S
The AirTAC PBJ10X150-50S is a double-acting, adjustable-stroke pen-size mini cylinder with a built-in magnet. A rear adjuster screw and lock nut shorten the retract end, giving an effective stroke range of 100-150 mm from a 150 mm nominal length. The extend end remains fixed. Force is identical to a standard PB cylinder of this bore, delivering about 39.3 N push at 0.5 MPa.
This 10 mm bore variant features a Ø4 mm piston rod, an M5x0.8 air port, and a fixed TPU bumper at each end. Because the 150 mm stroke exceeds the 100 mm max standard for this bore, it is a non-standard, made-to-order length. The slim SUS304 stainless body suits tight jigs. The built-in magnet works with reed or electronic switches.

| Bore size | Ø10 mm |
| Rod diameter | Ø4 mm |
| Nominal stroke | 150 mm |
| Adjustable window | 50 mm (100–150 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 PBJ10X150-50S Is Used
Changeover Fixtures
Dial in the retract stop from 100 to 150 mm when switching product families on a shared jig, avoiding hardware swaps.
Trial Stops
Set intermediate retract positions during prototype testing to find the exact engagement distance before finalizing hard stops.
Variable Depth Insertion
Adjust the back position on the machine to tune insertion depths without needing to reorder a different fixed-length cylinder.
Is the Airtac PBJ Adjustable Pen-Type Cylinder PBJ10X150-50S the Right Cylinder?
When sizing, the 10 mm bore gives 39.3 N push at 0.5 MPa, sitting below the 12 mm bore (56.5 N) and above smaller mini sizes. Good practice loads a cylinder to about 60% of theoretical force, so plan for roughly 24 N of real work at 0.5 MPa. For vertical lifts, this equates to lifting about 2 kg safely with a 2:1 margin. Remember that only the retract end is adjustable; re-tighten the lock nut after setting to prevent vibration drift.
Because the thin Ø4 mm rod is meant for coaxial thrust, adding an external guide or linear bearing is recommended over this long 150 mm stroke to prevent side-load wear. The fixed TPU bumper only decelerates the last few mm; at mid speeds with real tooling mass, meter-out the exhaust or add an external shock absorber. Confirm ordering essentials: 10 mm bore, 150 mm stroke, 50 mm window, magnet, and mounting.
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 PBJ10X150-50S FAQ
The effective stroke range is 100-150 mm. At 0.5 MPa, push is 39.3 N and pull is 33 N. At the maximum 0.7 MPa operating pressure, push is 55 N and pull is 46.2 N.
A rear M4x0.7 adjuster screw shortens the retract end while the extend end stays fixed; re-tighten the lock nut after setting. A plain cylinder does not hold its load on air loss or when the valve is centered, so an external stop or rod lock is required for fail-safe holding.
