About the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X150-100S
The ACQJ40X150-100S is a double-acting, single-rod JIS compact cylinder featuring an external threaded stop with a lock nut that limits the extend stroke. You can fine-tune the extend end position directly on your machinery without swapping components. This unit provides a usable extend range of 50-150mm (a 150mm full stroke shortened by up to a 100mm window), while the retract stroke remains completely unaffected.
Because the adjuster only restricts travel length and not the internal piston area, the output force remains identical to a standard ACQ of the same bore. This long-stroke made-to-order variant exceeds the 100mm standard maximum for this bore size. It features a 16mm piston rod, an M8x1.25 female rod-end thread, and an M12x1.25 adjuster thread. The body incorporates fixed elastomer bumpers and magnetic-switch grooves, utilizing the built-in -S magnet to work seamlessly with reed or electronic solid-state sensors.

| Rod thread | M8×1.25 (F) / M14×1.5 (B) |
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.
Theoretical Output Force (Ø40mm)
| 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.

Where the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X150-100S Is Used
Machining Fixture Stops
Dial in the exact clamping reach on machining fixtures during setup or material changes, using the external stop to prevent over-travel.
Product Changeover Diverters
Adjust the extend length on packaging line diverters to accommodate different carton widths without replacing the cylinder.
Trial End Positions
Establish safe trial end positions on new automated machinery by limiting the rod extension until final clearances are verified.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X150-100S the Right Cylinder?
When sizing this 40mm bore actuator, note it delivers 628.3N of push force and 527.8N of pull force at 0.5 MPa. If your application requires less force, stepping down to a 32mm bore yields 402.1N of push, whereas moving up to a 50mm bore provides 981.8N. A standard fixed-stroke ACQ is sufficient if your end position never varies. To order this adjustable version correctly, confirm the 40mm bore, the 150mm full stroke, the 100mm adjustment window, the -S magnet option, and the female rod thread.
Quick checklist
- ✓ Need on-machine end-position tuning?
- ✓ Full stroke and adjust window (mm)
- ✓ Force at your working pressure
- ✓ Magnet (S) for sensors?
- ✓ Female (blank) or male (B) rod thread
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Lock the adjuster nut after setting the stop.
- check The stop limits the EXTEND stroke only.
- check Avoid side load on the short piston rod.
- check Installation by qualified personnel per AirTAC docs.
Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X150-100S FAQ
This cylinder provides 628.3N push and 527.8N pull at 0.5 MPa, 879.6N push at 0.7 MPa, and a maximum push of 128 kgf at 1.0 MPa. The usable extend range is 50-150mm, created by subtracting the 100mm adjustment window from the 150mm full stroke.
No, the adjuster only changes the stroke length, keeping the force identical to a standard ACQ of the same bore. The cylinder uses fixed elastomer bumpers at both ends for end-of-stroke deceleration rather than an adjustable air cushion.
