Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X75-10B
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X75-10B 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 ACQJ32X75-10B
The AirTAC ACQJ32X75-10B is a double-acting JIS compact cylinder featuring a 32mm bore and a 75mm full stroke. An external threaded stop with a lock nut limits the extend end position, providing a usable extend range of 65-75mm. The retract stroke remains completely unaffected. This on-machine tuning capability allows you to dial in the exact end position without swapping out parts.
Because the piston area stays the same, the output force is identical to a standard ACQ of this bore. The rod end uses an M14x1.5 male thread for direct load coupling, while the M12x1.25 adjuster thread sets the stop. The body incorporates fixed NBR elastomer bumpers at each end for end-of-stroke deceleration and includes sensor grooves, though this specific configuration ships without a magnet.

| Series | ACQJ JIS compact adjustable-stroke cylinder |
| Bore size | Ø32 mm |
| Full stroke | 75 mm |
| Adjuster thread | M12×1.25 |
| Port size | PT1/8 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.15 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 30 – 500 mm/s |
| 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 ACQJ32X75-10B Is Used
Machining Fixture Stops
Dial in the exact clamping reach on a CNC machining fixture during first-article inspection, shortening the extend stroke by up to 10mm without disassembling the tooling.
Carton Forming Adjustments
Accommodate varying package sizes on a packaging line by fine-tuning the cylinder's extend end position on the machine to handle different folding depths instantly.
Assembly Press Positioning
Set precise trial end positions for pressing bearings on an assembly line, allowing operators to tweak the 65-75mm stroke window to prevent over-travel on delicate parts.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X75-10B the Right Cylinder?
If your setup requires slightly less thrust, the 25mm bore provides 245.4N push at 0.5MPa, whereas stepping up to the 40mm bore yields 628.3N. Choose this 32mm bore if 402.1N push force at 0.5MPa fits your requirement. A fixed-stroke ACQ cylinder is sufficient if your extend position never needs field adjustments. When ordering, confirm the 75mm full stroke, 10mm window, male M14x1.5 rod thread, and whether you need the -S magnet option for reed or solid-state switches.
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 ACQJ32X75-10B FAQ
The usable extend range is 65-75mm (75mm full stroke minus the 10mm window). It delivers 402.1N push and 301.6N pull at 0.5MPa, 562.9N push at 0.7MPa, and a maximum push of 82kgf at 1.0MPa. The force is identical to a standard ACQ of the same bore.
An external M12x1.25 threaded stop with a lock nut limits the extend stroke only; the retract stroke is unaffected. The adjuster changes stroke length, not force. The cylinder uses fixed NBR elastomer bumpers, not adjustable air cushions. It will not hold a load on air loss, so use an external rod lock for fail-safe holding.
