Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X75-40S
The AirTAC Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X75-40S is a double-acting, double-rod pen-size mini cylinder whose rear rod carries a stroke adjuster. On a Ø16mm bore it gives a nominal 75mm stroke with a 40mm fine-adjustable window — settable from 35 to 75mm, so you set the end position without changing hardware.

About the Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X75-40S
The AirTAC PBJ16X75-40S is a double-acting, double-rod pen-size mini cylinder with a 40 mm adjustable window. A rear screw and lock nut shorten the retract end, yielding an effective stroke range of 35-75 mm. The extend end remains fixed. The M5x0.8 air port and SUS304 stainless build fit tight jigs.
The built-in magnet supports reed or electronic switches. Because the thin Ø5 mm piston rod handles coaxial thrust, add an external guide for off-axis loads. The fixed TPU bumper decelerates the last few mm; at high speeds with real mass, meter-out the exhaust.

PBJ is a double-rod cylinder: the rear rod carries the stroke adjuster, which sets the stroke end within the adjustable window. Confirm the set position against the product label before installation.
Theoretical Output Force (Ø16mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 90.7 N | 90.7 N |
| 0.7 MPa (max) | 126.9 N | 126.9 N |
The rear rod passes through the rear cover, so both piston faces lose rod area: push is shown at the annular-area value (conservative), lower than a single-rod PB push of the same bore. Size with a friction margin.

Where the Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X75-40S Is Used
Variable-Depth Insertion
Dial in precise press depths on the fly. The 35-75 mm retract window lets you test multiple insertion heights during commissioning without swapping cylinders.
Quick Changeover Fixtures
Adapt pick-and-place tooling to new part sizes rapidly. Turn the rear M5x0.8 adjuster to shift the back position, then lock the nut for repeatable cycles.
Trial Stop Positioning
Set exact end-of-stroke stops for delicate components. The fixed TPU bumper absorbs final impact while the screw brings the retract point exactly where needed.
Is the Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X75-40S the Right Cylinder?
Stepping down to a 12 mm bore drops push to 56.5 N, while no larger bore exists in the PBJ series. The rear adjuster tunes the retract end only; set your length, then re-tighten the lock nut so vibration does not drift the screw. Confirm ordering essentials: 16 mm bore, 75 mm nominal stroke, 40 mm window, S magnet, and any LB or FA mount.
Quick checklist
- ✓ Need to fine-tune the end position on site
- ✓ Retract end sits within 35–75 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 Double rod: the rear rod carries the stroke adjuster.
- 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 PBJ16X75-40S FAQ
The effective stroke range is 35-75 mm. At 0.5 MPa, push is 100.5 N and pull is 90.7 N. At the 0.7 MPa maximum, push is 140.7 N and pull is 126.9 N. Adjusting the stroke does not alter these forces.
A rear screw shortens the retract end only; the extend end is fixed. You set the position, then re-tighten the lock nut to prevent vibration drift. The built-in S magnet works with reed or electronic switches.
