Airtac PBJ Adjustable Pen-Type Cylinder PBJ10X150-75
The AirTAC Airtac PBJ Adjustable Pen-Type Cylinder PBJ10X150-75 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 75mm fine-adjustable window — settable from 75 to 150mm, so you set the end position without changing hardware.

About the Airtac PBJ Adjustable Pen-Type Cylinder PBJ10X150-75
The AirTAC PBJ10X150-75 is a double-acting, single-rod pen-size mini cylinder featuring a rear adjuster screw that shortens the retract end. The effective stroke range is 75-150 mm (nominal 150 minus up to a 75 mm window), while the extend end remains fixed. Output force is identical to a standard PB of the same 10 mm bore, delivering 39.3 N push at 0.5 MPa. Because 150 mm exceeds the 100 mm max standard stroke for this bore, this configuration is non-standard and made-to-order.
The slim SUS304 stainless body saves space in tight jigs. A fixed TPU bumper decelerates the piston near stroke end, but over long strokes the thin Ø4 mm rod is strictly for coaxial thrust—add an external linear bearing if you encounter off-axis loads. The air port is M5x0.8 and the adjuster thread is M4x0.7. Plan for a safe working load of about 24 N (roughly 60% of the 0.5 MPa figure) to account for seal friction. Without live air pressure, the piston drifts, so an external rod lock is required for fail-safe holding.

| Model | Airtac PBJ Adjustable Pen-Type Cylinder PBJ10X150-75 |
|---|---|
| Series | PBJ JIS pen-size adjustable-stroke cylinder |
| Bore size | Ø10 mm |
| Rod diameter | Ø4 mm |
| Nominal stroke | 150 mm |
| Adjustable window | 75 mm (75–150 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 PBJ10X150-75 Is Used
Changeover Fixtures
Dial in the retract distance from 75 to 150 mm during product changeovers without machining new hard stops or ordering alternate cylinders.
Trial Insertion Stops
Fine-tune the depth of insertion pins on trial assemblies, locking the M4x0.7 nut once the perfect end position is found.
Variable Depth Pressing
Set precise retract endpoints for light-duty pressing tasks, relying on the 39.3 N push force at 0.5 MPa for consistent coaxial thrust.
Is the Airtac PBJ Adjustable Pen-Type Cylinder PBJ10X150-75 the Right Cylinder?
When sizing this 10 mm bore, note that stepping up to a 12 mm bore yields 56.5 N push at 0.5 MPa, while dropping down is not an option as 10 mm is the smallest available. This model provides 39.3 N push and 33 N pull at 0.5 MPa. Remember that the rear M4x0.7 screw only modifies the retract position; the extend end is fixed. After dialing in your 75-150 mm range, re-tighten the lock nut to prevent vibration drift. Confirm your ordering essentials: 10 mm bore, 150 mm stroke, 75 mm window, no magnet, and mounting choice.
Because the fixed TPU bumper only absorbs impact over the last few millimeters, high-speed cycling with heavy tooling mass will bottom it out. Meter-out the exhaust or install an external shock absorber for smooth deceleration. This plain PBJ does not use a sensor magnet.
Quick checklist
- ✓ Need to fine-tune the end position on site
- ✓ Retract end sits within 75–150 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 PBJ10X150-75 FAQ
This 10 mm bore cylinder delivers 39.3 N push and 33 N pull at 0.5 MPa, and 55 N push and 46.2 N pull at 0.7 MPa. The nominal stroke is 150 mm, but the rear adjuster screw provides an effective stroke range of 75-150 mm. The air port is M5x0.8.
A rear screw shortens the retract end, allowing you to set the effective stroke anywhere from 75 mm up to the full 150 mm. The extend end remains fixed. You must re-tighten the lock nut after setting your desired position to prevent vibration drift.
