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

About the Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X40-10S
The AirTAC PBJ16X40-10S is a JIS pen-size double-acting mini cylinder with a 10mm adjustable stroke window, yielding an effective range of 30-40mm. A rear M5x0.8 adjuster screw shortens the retract end, letting you dial in the exact length during commissioning without buying new hardware. The extend end remains fixed.
The slim body features a SUS304 stainless barrel and rod, a fixed TPU bumper at each end, and a built-in magnet for position sensing. The air port is M5x0.8.

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 PBJ16X40-10S Is Used
Changeover Fixtures
Quickly dial in the 30-40mm retract length on the rear screw when swapping part families on a multi-product line, skipping custom spacers.
Trial Stops
Fine-tune the stopping position during prototype runs or depth checks, locking the nut once the exact 30-40mm window is proven.
Is the Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X40-10S the Right Cylinder?
Remember that only the retract position is field-settable, so verify your extend-end layout allows for the fixed stroke. Always re-tighten the lock nut after setting the M5x0.8 adjuster to prevent vibration drift.
Confirm your ordering essentials: 16mm bore, 40mm nominal stroke, 10mm window, S magnet, and mounting option.
Quick checklist
- ✓ Need to fine-tune the end position on site
- ✓ Retract end sits within 30–40 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 PBJ16X40-10S FAQ
The effective stroke range is 30-40mm. At 0.5MPa, push force is 100.5N and pull force is 90.7N. At the maximum 0.7MPa operating pressure, push is 140.7N and pull is 126.9N.
A rear M5x0.8 screw adjusts only the retract end, shortening the stroke up to 10mm; the extend end is fixed. You must re-tighten the lock nut after setting to prevent vibration drift. The -S suffix means a built-in piston magnet works with AirTAC reed or electronic switches.
