Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X75-10B
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X75-10B is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø40mm 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 ACQJ40X75-10B
The AirTAC ACQJ40X75-10B is a JIS double-acting compact cylinder with a 40mm bore and 75mm full stroke. An external threaded stop and lock nut lets you fine-tune the extend end position on the machine, yielding a usable extend range of 65 to 75mm. The retract stroke remains fixed at 75mm. Because the piston area is unchanged, the output force is identical to a standard ACQ of this bore.
This unit features a male M14x1.5 piston rod end that couples directly to your load. It includes a fixed elastomer bumper at each end for end-of-stroke deceleration rather than an adjustable air cushion. The body retains magnetic-switch grooves, though this specific SKU ships without a magnet. Operating pressure spans 0.15 to 1.0 MPa, and the rod diameter is 16mm.

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 ACQJ40X75-10B Is Used
Product Changeover Stops
Adjust the extend stop up to 10mm when switching between part families on a machining line, avoiding physical spacer changes.
Variable Press Fixtures
Dial in the exact clamping reach for different material thicknesses directly at the press without swapping cylinders.
Trial End Positions
Set precise extend endpoints during machine prototyping to test engagement distances before finalizing hard stops.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X75-10B the Right Cylinder?
If you need slightly less push force, the 32mm bore yields 402.1N push at 0.5 MPa, while stepping up to the 50mm bore provides 981.8N. A fixed-stroke ACQ suffices if your end position never varies. To order this adjustable version, confirm the 40mm bore, 75mm full stroke, 10mm window, the male rod thread, and whether you require the magnet option. The standard port is PT1/8.
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 ACQJ40X75-10B FAQ
The push force is 628.3N and pull is 527.8N at 0.5MPa, with a push of 879.6N at 0.7MPa and a max push of 128kgf at 1.0MPa. The full stroke is 75mm, and the 10mm window gives a usable extend range of 65 to 75mm.
The external M12x1.25 threaded stop with lock nut limits how far the rod extends, shortening the extend stroke only. The retract stroke is unaffected, and because the piston area is unchanged, the force remains identical to a standard ACQ. Fixed elastomer bumpers handle deceleration, so add an external shock absorber for high-energy loads.
