Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X80-100SB
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X80-100SB 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 ACQJ32X80-100SB
The AirTAC ACQJ32X80-100SB is a double-acting JIS compact cylinder with an external threaded stop and lock nut that limits the extend end position. It features a 32mm bore, an 80mm full stroke, and a 100mm adjustment window, yielding a usable extend range of 0-80mm. The retract stroke remains completely unaffected by this mechanism. Equipped with a male M14x1.5 piston rod end, it couples directly to your load.
Because the piston area is unchanged, the output force is identical to a standard ACQ of this bore, delivering 402.1N push at 0.5 MPa. The cylinder body uses fixed elastomer NBR bumpers at each end for deceleration rather than adjustable air cushions. It includes a built-in piston magnet for use with reed or electronic solid-state switches.

| Model | Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X80-100SB |
|---|---|
| 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 ACQJ32X80-100SB Is Used
Machining Fixture Stops
Dial in the exact extend reach on a CNC machining fixture to accommodate different raw part lengths without swapping out cylinder hardware.
Product Changeover Diverter
Quickly reposition a conveyor sorting gate for new packaging formats by turning the external M12x1.25 adjuster screw to shift the extend endpoint.
Carton Sealing Press
Set precise trial end positions on a packaging press to verify contact force before finalizing the stroke length for a new box size.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X80-100SB the Right Cylinder?
When sizing this 32mm bore actuator, note that a smaller 25mm bore provides 245.4N push at 0.5 MPa, while a larger 40mm bore yields 628.3N. If your extend end position is permanently fixed and never requires tuning, a standard ACQ32 cylinder without the external adjuster will suffice. To order, confirm the 32mm bore, 80mm full stroke, 100mm adjustment window, the -S magnet for sensing, and the -B male M14x1.5 rod 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 ACQJ32X80-100SB FAQ
The usable extend range is 0-80mm (80mm full stroke minus the 100mm window). Force is identical to a standard ACQ: 402.1N push and 301.6N pull at 0.5 MPa, 562.9N push at 0.7 MPa, and a maximum push of 82 kgf at 1.0 MPa.
An external threaded stop with a lock nut limits only the extend stroke length, leaving the retract stroke unaffected; force is unchanged because piston area remains the same. The cylinder uses fixed NBR bumpers for deceleration, but it will not hold its load on air loss, so an external rod lock or pilot-operated check valve is required for fail-safe holding.
