Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X80-75S
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X80-75S is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø32mm bore and 80mm 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 ACQJ32X80-75S
The AirTAC ACQJ32X80-75S is a double-acting JIS compact cylinder featuring an external M12x1.25 threaded stop with a lock nut. This mechanism limits the extend travel, allowing you to dial in the end position directly on your machinery. You get a usable extend range of 5 to 80 mm, while the retract stroke remains completely unaffected.
Because the piston area stays constant, output force is identical to a standard ACQ of the same bore. You retain the 402.1 N push and 301.6 N pull at 0.5 MPa. The 32 mm bore uses a PT1/8 port, a 16 mm rod, and includes a built-in magnet (-S) compatible with reed or solid-state switches. Fixed NBR elastomer bumpers absorb impact at both ends without needing adjustment.

| Series | ACQJ JIS compact adjustable-stroke cylinder |
| Bore size | Ø32 mm |
| Full stroke | 80 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 |

| 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 ACQJ32X80-75S Is Used
Machining Fixture Clamps
Dial in the exact clamping reach on a CNC machining center when raw material thickness varies, preventing over-travel without swapping hardware.
Product Changeover Stops
Adjust the extend end stop rapidly on a packaging line when switching between different carton sizes, minimizing machine setup time.
Prototype Probe Positioning
Fine-tune the extension distance for a testing probe assembly during R&D trials to find the optimal contact point against new components.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X80-75S the Right Cylinder?
Selecting this 32 mm bore actuator means sizing for your primary force requirement; it delivers 402.1 N push at 0.5 MPa. If your load is lighter, stepping down to a 25 mm bore yields 245.4 N push, whereas moving up to a 40 mm bore provides 628.3 N. Choose this adjustable variant when you need 5 to 80 mm of extend travel but require on-the-fly position tuning; a fixed-stroke ACQ is sufficient if your end stop never changes. Confirm your ordering details: 32 mm bore, 80 mm full stroke, 75 mm adjuster window, female M8x1.25 rod end, and the -S magnet.
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 ACQJ32X80-75S FAQ
The usable extend range is 5 to 80 mm (an 80 mm full stroke shortened by up to a 75 mm window). It generates a push of 402.1 N and pull of 301.6 N at 0.5 MPa, 562.9 N push at 0.7 MPa, and a maximum push of 82 kgf at 1.0 MPa.
No, the external M12x1.25 stop only limits travel length; the force remains identical to a standard ACQ because piston area is unchanged. Deceleration is handled by fixed NBR elastomer bumpers at both ends, not an adjustable air cushion.
