Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X80-10S
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X80-10S 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 ACQJ32X80-10S
The AirTAC ACQJ32X80-10S is a double-acting JIS compact cylinder featuring an external threaded stop with a lock nut that limits the extend end position. You can fine-tune the usable extend range from 70 mm up to the full 80 mm on the machine, while the retract stroke remains unaffected. It includes a built-in piston magnet (-S) for position sensing.
Because the piston area is unchanged, output force is identical to a standard ACQ of the same bore, delivering 402.1 N push at 0.5 MPa. The unit uses a PT1/8 port, a 16 mm rod, and fixed elastomer bumpers at both ends for end-of-stroke deceleration.

| Model | Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X80-10S |
|---|---|
| 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 |
| 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 ACQJ32X80-10S Is Used
Machining Fixture Clamps
Dial in the exact clamping extension between 70 and 80 mm during setup to accommodate varying workpiece thicknesses without machining new stops.
Carton Sealing Heads
Adjust the extend end position on the fly to match different package heights, ensuring consistent sealing pressure across product changeovers.
Assembly Press Stations
Establish trial end positions for pressing bearings, tweaking the external stopper nut to find the perfect insertion depth before finalizing the cycle.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X80-10S the Right Cylinder?
When sizing this 32 mm bore unit, consider the neighbouring capacities: a 25 mm bore yields 245.4 N push at 0.5 MPa, while a 40 mm bore provides 628.3 N. If your extend endpoint never varies, a fixed-stroke ACQ cylinder is sufficient. For the ACQJ32X80-10S, confirm the 80 mm full stroke, the 10 mm adjuster window, the -S magnet, and the default female M8x1.25 rod-end thread.
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 ACQJ32X80-10S FAQ
The usable extend range is 70-80 mm (80 mm full stroke minus a 10 mm window). It generates 402.1 N push and 301.6 N pull at 0.5 MPa, 562.9 N push at 0.7 MPa, and a maximum push of 82 kgf at 1.0 MPa.
An external M12x1.25 threaded stop with a lock nut limits the extend stroke; the retract stroke is unaffected. The adjustment changes the stroke length only, so force remains identical to a standard ACQ. The cylinder uses fixed elastomer bumpers, and the -S magnet works with reed or electronic switches.
