Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X90-30S
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X90-30S 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 ACQJ32X90-30S
The AirTAC ACQJ32X90-30S is a double-acting JIS compact cylinder with a 32mm bore and a 90mm full stroke. An external M12x1.25 threaded stop and lock nut lets you fine-tune the extend end position on the machine, yielding a usable extend range of 60-90mm. The retract stroke remains completely unaffected by this adjustment.
Because the piston area is unchanged, output force matches a standard ACQ exactly: 402.1N push and 301.6N pull at 0.5MPa. The body uses a fixed elastomer bumper at each end for end-of-stroke deceleration, and the included -S magnet works with reed or solid-state switches in the built-in sensor grooves.

| 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 ACQJ32X90-30S Is Used
Machining Fixture Stops
Dial in the extend position of clamping arms on a CNC mill fixture to accommodate raw part tolerances without swapping out cylinder hardware.
Packaging Format Changeover
Adjust the pusher rod end position on a carton sealing line to handle different box widths quickly during product family transitions.
Assembly Press Trials
Set trial extend endpoints for pressing bearings on an automated assembly rig, finding the exact travel distance before finalizing the mechanical stops.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X90-30S the Right Cylinder?
This 32mm bore provides 402.1N push at 0.5MPa, sitting between the 25mm bore (245.4N push) and the 40mm bore (628.3N push). If your extend endpoint never varies, a fixed-stroke ACQ cylinder is sufficient. When ordering, confirm the 32mm bore, 90mm full stroke, 30mm adjuster window, the -S magnet option, 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 ACQJ32X90-30S FAQ
At 0.5MPa it provides 402.1N push and 301.6N pull, with a 562.9N push at 0.7MPa and a maximum push of 82kgf at 1.0MPa. The 90mm full stroke features a 30mm adjustable window, giving a usable extend range of 60-90mm.
The external M12x1.25 threaded stop with lock nut limits the extend length only, meaning output force remains identical to a standard ACQ. The cylinder relies on fixed elastomer bumpers for deceleration, so for high kinetic energy loads you should add an external shock absorber.
