Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X40-30
The AirTAC Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X40-30 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 40mm stroke with a 30mm fine-adjustable window — settable from 10 to 40mm, so you set the end position without changing hardware.

About the Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X40-30
The AirTAC PBJ16X40-30 is a double-acting, pen-size mini cylinder featuring a 30mm adjustable-stroke window. A rear adjuster screw with a lock nut shortens the retract end, providing an effective stroke range of 10 to 40mm. This allows on-machine tuning without ordering new hardware. The extend end remains fixed.
The Ø16mm body uses an M5x0.8 port, a Ø5mm stainless rod, and a fixed TPU bumper at each end.

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 PBJ16X40-30 Is Used
Changeover Fixtures
Dial in the exact retract position on the fly when swapping product families, eliminating the downtime of physically swapping cylinders or spacers.
Trial Insertion Stops
Fine-tune the penetration depth during prototype testing. Set the stroke from 10mm up to 40mm to find the perfect insertion force without tooling changes.
Variable Depth Pressing
Adjust the retract end to press components to varying depths on a single station. The fixed TPU bumper ensures consistent end-of-stroke deceleration.
Is the Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X40-30 the Right Cylinder?
For sizing context, dropping to a Ø12mm bore reduces push force to 56.5N at 0.5MPa, while this Ø16mm unit provides 100.5N. Remember that only the retract position is settable; the extend end is fixed. Always re-tighten the lock nut after setting to prevent vibration drift.
Confirm your ordering essentials: 16mm bore, 40mm nominal stroke, 30mm adjuster window, no magnet, and your preferred mounting option. The rear adjuster uses an M5x0.8 thread.
Quick checklist
- ✓ Need to fine-tune the end position on site
- ✓ Retract end sits within 10–40 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 PBJ16X40-30 FAQ
The effective stroke range is 10-40mm.
A rear M5x0.8 adjuster screw shortens the retract end by up to 30mm, while the extend end remains fixed. You must re-tighten the lock nut after setting your desired length to prevent vibration drift.
