Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X75-20
The AirTAC Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X75-20 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 20mm fine-adjustable window — settable from 55 to 75mm, so you set the end position without changing hardware.

About the Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X75-20
The AirTAC PBJ16X75-20 is a double-acting, double-rod pen-size mini cylinder with a 20mm adjustable stroke window. A rear adjuster screw shortens the retract end, giving an effective stroke range of 55-75mm. The extend end remains fixed. The M5x0.8 air port and Ø5mm rod keep the body slim.
The SUS304 stainless barrel and fixed TPU bumper suit tight jigs and light end-of-arm tooling. The rear M5x0.8 adjuster lets you tune the retract length during commissioning.

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 PBJ16X75-20 Is Used
Changeover Fixtures
Dial in the exact retract distance when swapping product families on a shared jig, using the rear screw to hit 55-75mm without machining new stops.
Trial Stops
Fine-tune the end position during prototype runs, locking the nut once the optimal 55-75mm travel is found for the test rig.
Variable-Depth Insert
Set precise downward insertion depths for press-fit tasks, adjusting the retract end to accommodate different part heights on the fly.
Is the Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X75-20 the Right Cylinder?
The rear screw shortens the retract end only, so verify your layout has rear clearance. Re-tighten the lock nut after setting to prevent vibration drift. Confirm ordering essentials: bore, stroke, window, magnet S, and mount.
The thin Ø5mm rod handles coaxial thrust well. Over long strokes or off-axis loads, add an external guide or linear bearing to prevent side-load damage. A plain body does not hold position on air loss, so fit an external stop for fail-safe load holding.
Quick checklist
- ✓ Need to fine-tune the end position on site
- ✓ Retract end sits within 55–75 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 PBJ16X75-20 FAQ
The effective stroke range is 55-75mm. At 0.5MPa, push is 100.5N and pull is 90.7N. At the 0.7MPa maximum, push is 140.7N and pull is 126.9N. The air port is M5x0.8 and the rod-end thread is M10x1.0.
A rear M5x0.8 adjuster screw shortens the retract end only; the extend end is fixed. You set the travel from 55 to 75mm on the machine, then re-tighten the lock nut to prevent vibration drift. The fixed TPU bumper decelerates the last few mm, but at high speeds with real mass, meter-out the exhaust or add an external shock absorber.
