Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X75-30B
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X75-30B 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 ACQJ32X75-30B
The AirTAC ACQJ32X75-30B is a double-acting JIS compact cylinder featuring a 32mm bore and a 75mm full stroke. An external M12x1.25 threaded stop with a lock nut lets you fine-tune the extend end position on the machine, providing a usable extend range of 45-75mm. The retract stroke remains completely unaffected by this adjustment.
Because the piston area is unchanged, output force is identical to a standard ACQ of this bore. You get 402.1N push and 301.6N pull at 0.5MPa. This unit includes a male M14x1.5 rod-end thread for direct load coupling, fixed NBR elastomer bumpers at both ends, and a PT1/8 port. The body features sensor grooves, though this specific SKU ships without a magnet.

| Port size | PT1/8 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.15 – 1.0 MPa |
| Proof pressure | 1.5 MPa |

| 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 ACQJ32X75-30B Is Used
Machining Fixture Stops
Dial in the exact extend position for varying part lengths on a CNC lathe loader without machining new stop collars.
Carton Changeover
Quickly reposition the extend stroke during packaging line format changes to accommodate different box widths.
Press Trial Positions
Set precise trial end positions on light assembly presses, testing clamping depth before finalizing mechanical stops.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X75-30B the Right Cylinder?
When sizing this 32mm bore, stepping down to a 25mm bore yields 245.4N push at 0.5MPa, while stepping up to a 40mm bore provides 628.3N push. If your extend position never needs field adjustment, a fixed-stroke ACQ cylinder is simpler and suffices. To order this adjustable version correctly, confirm the 32mm bore, 75mm full stroke, 30mm adjustment window, the male M14x1.5 rod thread, and that no magnet (-S) is required.
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 ACQJ32X75-30B FAQ
The usable extend range is 45-75mm (75mm full stroke minus the 30mm adjustment window). Force is identical to a standard ACQ: 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 retract stroke remains unaffected.
An external M12x1.25 threaded stop with a lock nut limits the extend stroke length without changing the piston area, so force is unchanged. The cylinder uses fixed NBR elastomer bumpers at each end, not adjustable air cushions. The body has sensor grooves, but this model ships without a magnet.
