Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X75-75
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X75-75 is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø32mm bore and 75mm full stroke. Turn the stop to fine-tune the end position on the machine without changing parts.

About the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X75-75
The AirTAC ACQJ32X75-75 is a double-acting JIS compact cylinder with an external threaded stop and lock nut that limits the extend end position. With a full stroke of 75 mm and a 75 mm adjustment window, the usable extend range runs from 0 mm up to 75 mm. The retract stroke remains completely unaffected by this mechanism.
Because the piston area is unchanged, output force equals a standard ACQ of the same 32 mm bore, delivering 402.1 N push at 0.5 MPa. The body features fixed elastomer bumpers at both ends and integrated magnetic-switch grooves. It uses a PT1/8 port and a 16 mm piston rod with an M8x1.25 female rod-end thread.

| 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 (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 302 N |
| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 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 ACQJ32X75-75 Is Used
Product Changeover Stops
Adjust the extend end position on a packaging line when switching carton sizes, using the external M12x1.25 adjuster to dial in the new reach without disassembling the tooling.
Trial End Positions
Fine-tune the clamping reach on a machining fixture during first-article runs, testing different extend lengths from 0 to 75 mm to find the exact contact point.
Setup-Varying Fixtures
Modify the pusher depth on an assembly station for varying part heights, relying on the fixed elastomer bumper to absorb the impact at the adjusted end position.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X75-75 the Right Cylinder?
This 32 mm bore provides 402.1 N push and 301.6 N pull at 0.5 MPa. If your setup needs less force, the 25 mm bore yields 245.4 N push, while the 40 mm bore offers 628.3 N push for heavier demands. A fixed-stroke ACQ suffices if your extend position never varies. When ordering, confirm the 75 mm full stroke, 75 mm window, female rod thread, and whether a magnet (-S) is needed for sensors.
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 ACQJ32X75-75 FAQ
This 32 mm bore cylinder provides 402.1 N push and 301.6 N pull at 0.5 MPa, 562.9 N push at 0.7 MPa, and a maximum push of 82 kgf at 1.0 MPa. The full stroke is 75 mm with a 75 mm adjustment window, giving a usable extend range of 0-75 mm. The retract stroke remains fixed at its full length.
An external M12x1.25 threaded stop with a lock nut limits the extend stroke so you can tune the end position on the machine without swapping parts. This adjuster changes the stroke length only, leaving the output force identical to a standard ACQ. Deceleration is handled by fixed elastomer bumpers at both ends, not an adjustable air cushion.
