Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X75-50
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X75-50 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 ACQJ32X75-50
The AirTAC ACQJ32X75-50 is a double-acting JIS compact cylinder with a 32mm bore and 75mm full stroke. An external threaded stop with a lock nut limits the extend end position, yielding a usable forward range of 25-75mm. The retract stroke remains unaffected by this adjustment.
Because the piston area is unchanged, output force equals a standard ACQ of this size, delivering 402.1N push and 301.6N pull at 0.5 MPa. The body features sensor grooves for magnetic switches, though this specific SKU ships without a magnet. Fixed NBR elastomer bumpers handle end-of-stroke deceleration.

| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.15 – 1.0 MPa |
| Proof pressure | 1.5 MPa |

| 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 ACQJ32X75-50 Is Used
Machining Fixture Stops
Dial in the exact clamping reach on a CNC milling vise without fabricating custom spacer plates.
Carton Size Changeover
Rapidly modify the folding stroke depth on packaging lines when switching between different box dimensions.
Press Trial Positions
Safely test new bending depths on a light-duty metal forming press by limiting the forward travel.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X75-50 the Right Cylinder?
When sizing, a 25mm bore yields 245.4N push while a 40mm bore provides 628.3N at 0.5 MPa. If your setup never requires altering the extend endpoint, a fixed-stroke ACQ32X75 is simpler. To order, confirm the 32mm bore, 75mm full stroke, 50mm window, female M8x1.25 rod thread, and PT1/8 port.
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 ACQJ32X75-50 FAQ
It provides 402.1N push and 301.6N pull at 0.5 MPa, 562.9N push at 0.7 MPa, and a maximum push of 82kgf at 1.0 MPa. The usable extend range is 25-75mm (75mm full stroke minus a 50mm window).
An M12x1.25 external threaded stop with a lock nut physically limits how far the rod extends. It changes stroke length only, so force remains identical to a standard ACQ. Fixed NBR bumpers decelerate the piston at both ends.
