Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X80-75S
The AirTAC Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X80-75S 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 80mm stroke with a 75mm fine-adjustable window — settable from 5 to 80mm, so you set the end position without changing hardware.

About the Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X80-75S
The AirTAC PBJ16X80-75S is a double-acting, pen-size mini cylinder with an adjustable stroke. A rear adjuster screw and lock nut shorten the retract end, giving an effective stroke range of 5-80 mm. The extend end remains fixed.
The body features a SUS304 stainless barrel and a slim profile for tight jigs. It includes a fixed TPU bumper at each end and a built-in magnet (-S) for position sensing. Good practice loads a cylinder to roughly 60% of its theoretical force; plan for about 60 N of real work at 0.5 MPa. The thin Ø5 mm piston rod handles coaxial thrust, so add an external guide for off-axis loads.

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 PBJ16X80-75S Is Used
Changeover Fixtures
Dial in the exact retract distance when swapping part families on a single fixture, using the 5-80 mm range to avoid machining new stops.
Trial Stops
Set precise end positions during prototyping to find the optimal insertion depth before committing to a hard mechanical stop.
Variable-Depth Insertion
Adjust the back position for different material thicknesses on the fly, keeping the extend stroke fixed for consistent contact.
Is the Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X80-75S the Right Cylinder?
Stepping down to a 12 mm bore drops the push to 56.5 N, while a larger 20 mm bore offers more force if needed. The M5x0.8 port and M10x1.0 rod-end thread are fixed by the bore. Remember that only the retract position is settable; the extend end is fixed.
After dialing in your 5-80 mm range, re-tighten the lock nut to prevent vibration drift. To order, confirm the 16 mm bore, 80 mm nominal stroke, 75 mm window, the -S magnet for reed or electronic switches, and your mounting choice.
Quick checklist
- ✓ Need to fine-tune the end position on site
- ✓ Retract end sits within 5–80 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 PBJ16X80-75S FAQ
The effective stroke range is 5-80 mm. Force is unchanged from a standard PB 16 mm bore: push is 100.5 N and pull is 90.7 N at 0.5 MPa. At the 0.7 MPa maximum, push is 140.7 N and pull is 126.9 N.
A rear M5x0.8 adjuster screw shortens the retract end by up to 75 mm, while the extend end is fixed. You must re-tighten the lock nut after setting to prevent vibration drift. A plain cylinder does not hold position on air loss; use an external stop for fail-safe holding.
