Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X150-40
The AirTAC Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X150-40 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 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 PBJ16X150-40
The AirTAC PBJ16X150-40 is a double-acting, single-rod pen-size mini cylinder with a 40 mm adjustable stroke window. A rear M5x0.8 adjuster screw shortens the retract end, yielding an effective stroke range of 110-150 mm. The extend end remains fixed. Output force matches a standard PB body of the same bore, delivering 100.5 N push at 0.5 MPa without any penalty for the adjustment capability.
Built with a SUS304 stainless barrel and rod, this slim 16 mm bore cylinder saves space in tight jigs. It uses an M5x0.8 air port and a fixed TPU bumper at each end. For practical sizing, plan for a safe working load of about 60 N (roughly 60% of the 0.5 MPa rating) to account for seal friction and smooth travel.

| Model | Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X150-40 |
|---|---|
| Series | PBJ JIS pen-size adjustable-stroke cylinder |
| Bore size | Ø16 mm |
| Rod diameter | Ø5 mm |
| Nominal stroke | 150 mm |
| Adjustable window | 40 mm (110–150 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 PBJ16X150-40 Is Used
Variable-Depth Insertion
Dial in precise press depths for electronic pins or connectors during prototype runs, shifting the retract stop within the 110-150 mm window without swapping cylinders.
Quick Changeover Fixtures
Adapt pick-and-place end-of-arm tooling to new part heights rapidly by turning the rear screw, locking the nut, and resuming production immediately.
Trial Stop Positioning
Set temporary mechanical stops for testing component alignment in assembly jigs, fine-tuning the back position until the exact process length is proven.
Is the Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X150-40 the Right Cylinder?
When sizing this 16 mm bore unit, note the adjacent options: a 12 mm bore yields 56.5 N push, while stepping up is unnecessary here as 16 mm already provides 100.5 N at 0.5 MPa. Remember that the rear screw only tunes the back position; the extend stroke is fixed. Always re-tighten the lock nut after setting your 110-150 mm range to prevent vibration drift. Confirm your ordering essentials: 16 mm bore, 150 mm nominal stroke, 40 mm window, and any required LB or FA mount.
Because the rod is a slender Ø5 mm over a 150 mm stroke, it is built for coaxial thrust. Avoid side loads by adding an external guide or linear bearing for off-axis tooling. The fixed TPU bumper only decelerates the last few mm, so meter-out the exhaust or add an external shock absorber when cycling real tooling mass at higher speeds.
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 PBJ16X150-40 FAQ
The effective stroke range is 110-150 mm. At 0.5 MPa the push force is 100.5 N and pull is 90.7 N. At the maximum 0.7 MPa operating pressure, push is 140.7 N and pull is 126.9 N. These figures exactly match a standard PB cylinder of the same bore.
The rear M5x0.8 screw shortens only the retract end; the extend end is fixed. You must re-tighten the lock nut after setting to prevent vibration drift. A plain cylinder does not hold its load on air loss—the piston drifts and the bumper only decelerates near stroke end, so use an external stop for a fail-safe hold.
