Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X75-75B
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X75-75B 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 ACQJ32X75-75B
The AirTAC ACQJ32X75-75B 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 limits the extend end position, providing a usable extend range of 0-75mm. You can fine-tune the forward stroke directly on the machine without swapping parts, while the retract stroke remains unaffected.
Because the adjuster only alters travel length and not piston area, output force stays identical to a standard ACQ of this size. At 0.5 MPa it delivers 402.1N push and 301.6N pull. This variant includes a male M14x1.5 rod-end thread for direct load coupling, fixed NBR elastomer bumpers at both ends, and a PT1/8 port. It ships without a magnet, though the body retains sensor grooves.

|---|---|
| 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 ACQJ32X75-75B Is Used
Machining Fixture Stops
Dial in the exact extend position of a 32mm bore clamping pin on a CNC mill during part-changeover without machining new spacers.
Carton Forming Arms
Adjust the push-out depth of a folding flap on a packaging line to handle varying box sizes on the fly within the 0-75mm window.
Press Fit Probing
Set trial end positions for a light-duty assembly press, relying on the 402.1N push force to seat components precisely.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X75-75B the Right Cylinder?
When sizing this unit, stepping down to a 25mm bore yields 245.4N push @0.5MPa, whereas moving up to a 40mm bore provides 628.3N push. Choose the 32mm bore if your fixture requires up to 82kgf max push at 1.0MPa. If your application never needs end-position changes, a fixed-stroke ACQ cylinder is sufficient. For this adjustable model, confirm the 75mm full stroke, the 75mm window, the lack of a magnet, and the male rod thread when ordering.
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 ACQJ32X75-75B FAQ
This 32mm bore cylinder has a usable extend range of 0-75mm. It outputs 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 because the adjuster changes stroke length only.
An external M12x1.25 threaded stop with a lock nut mechanically limits the extend travel. The retract stroke is unaffected, and fixed elastomer bumpers decelerate the piston at both ends. A plain compact cylinder does not hold its load if air is lost; for a fail-safe hold, install an external rod lock or pilot-operated check valve.
