The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X5-10B is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø40mm bore and 5mm full stroke. Turn the stop to fine-tune the end position on the machine without changing parts.
The AirTAC ACQJ40X5-10B is a double-acting JIS compact cylinder with an external threaded stop and lock nut that limits the extend end position. With a 5mm full stroke and a 10mm adjustment window, the usable extend range is 0-5mm. The retract stroke remains completely unaffected. An M12x1.25 adjuster thread allows precise on-machine tuning without swapping parts.
Because the piston area stays the same, force is identical to a standard ACQ of this bore. You get 628.3N push and 527.8N pull at 0.5MPa. The 16mm rod features an M14x1.5 male thread for direct load coupling. The body includes fixed NBR elastomer bumpers at both ends and integrated sensor grooves, though this specific unit ships without a magnet.

Specifications follow the official AirTAC ACQJ datasheet. The adjustable stop shortens the EXTEND stroke only; the piston area — and therefore the force — is the same as a standard ACQ of this bore. Adjustable window options: 10/20/30/40/50/75/100 mm.
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 kgf | |
Force equals a standard ACQ of the same bore — the adjuster changes stroke length, not piston area. Actual usable force is lower due to friction; size with a safety margin.

For a 40mm bore, this cylinder yields 628.3N push and 527.8N pull at 0.5MPa, with a maximum push of 128kgf at 1.0MPa. Stepping down to a 32mm bore provides 402.1N push, while a 50mm bore offers 981.8N push at 0.5MPa. If your application requires a fixed 5mm extend position every time without variation, a standard ACQ40X5 will suffice. When ordering this adjustable version, confirm the 40mm bore, 5mm full stroke, 10mm window, male M14x1.5 rod thread, and the absence of a magnet.
Quick checklist
The usable extend range is 0-5mm (5mm full stroke minus up to 10mm). It delivers 628.3N push and 527.8N pull at 0.5MPa, 879.6N push at 0.7MPa, and a max push of 128kgf at 1.0MPa. The retract stroke is unaffected by the adjuster.
No, the external M12x1.25 threaded stop only changes the extend stroke length, not the piston area, so force remains identical to a standard ACQ. The cylinder uses fixed NBR bumpers for deceleration and ships without a sensor magnet. It will not hold a load on air loss without an external rod lock.
