The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X5-10 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 ACQJ40X5-10 is a double-acting JIS compact cylinder with a 5mm full stroke and a 40mm bore. An external threaded stop with a lock nut limits the extend end position, providing a usable extend range of 0-5mm. The retract stroke remains unaffected. Force output is identical to a standard ACQ of this bore, as the adjuster alters stroke length only.
This unit features a 16mm piston rod, a PT1/8 port, and a female M8x1.25 rod-end thread. The adjuster utilizes an M12x1.25 thread. Fixed elastomer NBR bumpers at both ends handle end-of-stroke deceleration. The body includes magnetic-switch grooves, though this specific configuration 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 |

| 0.7 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.

Dial in the exact clamping depth on machining fixtures. The external stop allows operators to tweak the 0-5mm extend position on the machine without swapping components.
Adjust end-of-stroke limits rapidly during packaging line format changes. The lock nut secures the new extend position quickly for varying carton sizes.
Test intermediate extend endpoints during automated assembly machine commissioning. Fine-tune the rod extension safely before locking down the final cycle.
When sizing this actuator, note the 40mm bore yields 628.3N push and 527.8N pull at 0.5MPa. Stepping down to a 32mm bore drops push force to 402.1N, while a 50mm bore increases it to 981.8N. If your application requires a fixed 5mm extend position without variation, a standard ACQ cylinder will suffice. To order, confirm the 40mm bore, 5mm full stroke, 10mm adjuster window, female rod thread, and that no magnet is required.
Quick checklist
This 40mm bore cylinder delivers 628.3N push and 527.8N pull at 0.5MPa, 879.6N push at 0.7MPa, and a maximum push of 128kgf at 1.0MPa. The full stroke is 5mm with a 10mm adjustment window, resulting in a usable extend range of 0-5mm.
The M12x1.25 threaded stop with lock nut physically limits how far the rod extends, shortening the stroke without changing the piston area. Therefore, force remains identical to a standard ACQ. The unit relies on fixed elastomer bumpers for deceleration and ships without a sensor magnet.
