Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X75-75S
The AirTAC Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X75-75S 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 75mm stroke with a 75mm fine-adjustable window, so you set the end position without changing hardware.

About the Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X75-75S
The AirTAC PBJ16X75-75S is a double-acting, single-rod pen-size mini cylinder featuring a 75mm adjustable stroke window. A rear adjuster screw and lock nut shorten the retract end, giving an effective range of 0-75mm. You can set the exact stroke on the machine without ordering new hardware. The extend end remains fixed.
Output force matches a standard PB cylinder of the same bore, giving 100.5N push and 90.7N pull at 0.5MPa. The Ø5mm piston rod has an M10x1.0 end thread, and the air port is M5x0.8. A built-in magnet works with reed or electronic switches. The slim SUS304 stainless body includes a fixed TPU bumper at each end. For real work, plan for a safe load of about 60N, which accounts for seal friction.

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.

Trial Stop Positioning
Fine-tune the backstop distance on testing jigs to find the exact contact point.
Is the Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X75-75S the Right Cylinder?
This 16mm bore provides 100.5N push at 0.5MPa. If you need less force, the 12mm bore gives 56.5N push; if you need more, you would step up to a larger profile. Remember that only the retract end is adjustable. After setting your 0-75mm range, re-tighten the lock nut so vibration does not drift the screw. The thin Ø5mm rod is for coaxial thrust, so add an external guide for off-axis loads. Confirm your bore, stroke, window, magnet, and mount before ordering.
Quick checklist
- ✓ Need to fine-tune the end position on site
- ✓ Retract end sits within 0–75 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 PBJ16X75-75S FAQ
The effective stroke range is 0-75mm. At 0.5MPa it provides 100.5N push and 90.7N pull. At the maximum 0.7MPa it provides 140.7N push and 126.9N pull.
A rear M5x0.8 adjuster screw shortens the retract end while the extend end stays fixed. You must re-tighten the lock nut after setting to prevent drift. The built-in magnet is compatible with reed or electronic switches.
