The AirTAC Airtac PBJ Adjustable Pen-Type Cylinder PBJ16X45-10S 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 45mm stroke with a 10mm fine-adjustable window — settable from 35 to 45mm, so you set the end position without changing hardware.
The AirTAC PBJ16X45-10S is a double-acting, double-rod pen-size mini cylinder with a 10mm adjustable stroke window. A rear adjuster screw with an M5x0.8 thread shortens the retract end, giving an effective stroke range of 35-45mm. The extend end remains fixed.
It features a SUS304 stainless steel barrel and rod, a slim 16mm body, and a fixed TPU bumper at each end. The -S suffix indicates a built-in piston magnet for position sensing. The air port is M5x0.8, and the rod-end thread is M10x1.0. For safe sizing, plan for about 60N of real work at 0.5MPa, which is roughly 60% of the theoretical push force to account for seal friction.

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.
| 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.

Dial in the exact retract position from 35 to 45mm during product changeovers without machining new stop blocks.
Micro-adjust the insertion depth on test jigs to find the optimal position before finalizing the assembly hardware.
Set precise pressing depths on light-duty end-of-arm tooling using the rear screw, leaving the extend stroke fixed.
Remember that only the retract position is field-adjustable; the extend end is fixed. Always re-tighten the lock nut after setting the 35-45mm range to prevent vibration drift. Confirm your ordering essentials: 16mm bore, 45mm nominal stroke, 10mm window, S magnet, and mounting choice.
Quick checklist
The effective stroke range is 35-45mm. 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. The piston rod is Ø5mm, the port is M5x0.8, and the rod-end thread is M10x1.0.
The rear M5x0.8 adjuster screw shortens the retract end only, while the extend end remains fixed. You must re-tighten the lock nut after setting to prevent vibration drift. The built-in magnet (-S) works with both AirTAC reed and electronic solid-state switches for position sensing.
