Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X90-20S
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X90-20S is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø32mm bore and 90mm 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 ACQJ32X90-20S
The AirTAC ACQJ32X90-20S is a double-acting JIS compact cylinder with an external threaded stop and lock nut on the rod-end side that limits how far the rod extends. You can fine-tune the extend end position on the machine without changing parts, yielding a usable extend range of 70-90 mm. The retract stroke remains unaffected. An M12x1.25 adjuster thread handles the stroke reduction.
Because the piston area is unchanged, the force is identical to a standard ACQ of this bore, delivering 402.1 N push and 301.6 N pull at 0.5 MPa. The cylinder body features fixed elastomer bumpers at each end and magnetic-switch grooves. The included -S magnet works with reed or electronic solid-state switches.
Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X90-20S Technical Specifications
| Model | Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X90-20S |
|---|---|
| Series | ACQJ JIS compact adjustable-stroke cylinder |
| Bore size | Ø32 mm |
| Full stroke | 90 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 ACQJ32X90-20S Is Used
Machining Fixture Stops
Dial in the extend position during product-changeover on a CNC lathe without machining custom spacers.
Assembly Line Clamps
Tune the clamping depth on automated assembly stations to accommodate varying part heights quickly.
Carton Sealing Arms
Adjust the folding arm end-point on packaging equipment to match different carton profiles on the fly.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X90-20S the Right Cylinder?
If your setup needs less push, the next bore down is 25 mm, providing 245.4 N push at 0.5 MPa. For heavier loads, stepping up to a 40 mm bore yields 628.3 N push at 0.5 MPa. A fixed-stroke ACQ suffices if your end position never varies. Confirm ordering essentials: 32 mm bore, 90 mm full stroke, 20 mm window, -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 ACQJ32X90-20S FAQ
Force is identical to a standard ACQ: push is 402.1 N and pull is 301.6 N at 0.5 MPa, push is 562.9 N at 0.7 MPa, and max push is 82 kgf at 1.0 MPa. The full stroke is 90 mm with a 20 mm window, giving a usable extend range of 70-90 mm. The external adjuster has an M12x1.25 thread.
An external threaded stop with a lock nut limits the extend stroke only; the retract stroke is unaffected and force remains unchanged. The cylinder uses fixed elastomer bumpers at each end, not adjustable air cushions. The -S magnet enables detection using reed or electronic solid-state switches.
