Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X90-75SB
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X90-75SB 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 ACQJ32X90-75SB
The AirTAC ACQJ32X90-75SB is a double-acting JIS compact cylinder featuring an external threaded stop and lock nut that restricts the extend end position. With a 90mm full stroke and a 75mm adjustment window, the usable extend range spans 15-90mm. The retract stroke remains completely unaffected by this mechanism. An M12x1.25 adjuster thread enables precise on-machine tuning without swapping components.
Because the piston area is unchanged, force output equals a standard ACQ of the same bore: 402.1N push and 301.6N pull at 0.5MPa, or 562.9N push at 0.7MPa. The unit includes a male M14x1.5 rod thread for direct load coupling, a PT1/8 port, and fixed elastomer bumpers at both ends. The -S magnet allows tracking via reed or solid-state switches installed in the body grooves.

| 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 |

| 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 ACQJ32X90-75SB Is Used
Machining Fixture Stops
Dial in the exact clamping reach on a CNC fixture during first-article inspection, shortening the extend stroke from 90mm down to 15mm as needed.
Packaging Changeover
Adapt cardboard folding mechanisms to different carton depths rapidly by turning the external stop nut, avoiding complete cylinder removal.
Assembly Press Trials
Test varying insertion depths for bearing presses on a test rig, relying on the 82kgf maximum push capacity to seat components.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X90-75SB the Right Cylinder?
When sizing this 32mm bore unit, consider the 25mm bore offering 245.4N push or the 40mm bore delivering 628.3N push at 0.5MPa. If your application requires a fixed end position every cycle, a standard ACQ cylinder is sufficient. To order this adjustable version correctly, confirm the 32mm bore, 90mm full stroke, 75mm window, the -S magnet, and the -B male rod end.
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 ACQJ32X90-75SB FAQ
It delivers 402.1N push and 301.6N pull at 0.5MPa, 562.9N push at 0.7MPa, and a maximum push of 82kgf at 1.0MPa. The full stroke is 90mm with a 75mm window, giving a usable extend range of 15-90mm.
The external M12x1.25 threaded stop limits the extend stroke length without altering piston area, so force remains identical to a standard ACQ. Fixed elastomer bumpers handle end-of-stroke deceleration, and the -S magnet works with reed or electronic switches in the body grooves.
