Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X200-75S
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X200-75S is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø32mm bore and 200mm 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 ACQJ32X200-75S
The AirTAC ACQJ32X200-75S is a double-acting, single-rod JIS compact cylinder engineered as a long-stroke, made-to-order variant (standard max for this bore is 100mm). It features an external M12x1.25 threaded stop with a lock nut on the extend side, allowing you to fine-tune the usable extend range from 125mm up to the full 200mm without swapping parts. The retract stroke remains completely unaffected.
Because the piston area is unchanged, output force is identical to a standard ACQ of the same size: 402.1N push and 301.6N pull at 0.5MPa. The unit includes a fixed elastomer NBR bumper at each end for end-of-stroke deceleration, and the -S magnet enables compatibility with both reed and solid-state electronic switches via its integrated grooves.

| Model | Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X200-75S |
|---|---|
| Series | ACQJ JIS compact adjustable-stroke cylinder |
| Bore size | Ø32 mm |
| Full stroke | 200 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 ACQJ32X200-75S Is Used
Machining Center Clamps
Dial in the exact 125-200mm clamping reach on CNC fixtures during product changeover without machining new stop collars.
Packaging Line Diverters
Adjust the extend position on the fly to handle varying carton widths on a packaging conveyor, utilizing the full 200mm stroke when needed.
Assembly Press Stops
Set precise end positions for trial runs on automated assembly presses, relying on the 402.1N push force at 0.5MPa to move tooling.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X200-75S the Right Cylinder?
This 32mm bore actuator provides 402.1N push at 0.5MPa, sitting between the smaller 25mm (245.4N) and larger 40mm (628.3N) options. Choose this specific long-stroke model when a 200mm extension is mandatory and you need on-machine adjustability; if the full 200mm reach is not required, a standard ACQJ32X100-75S might offer a shorter overall depth. Confirm your ordering essentials: 32mm bore, 200mm full stroke, 75mm adjuster 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 ACQJ32X200-75S FAQ
This 32mm bore cylinder generates 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 200mm, but the external adjuster allows you to shorten the extend stroke by up to 75mm, giving a usable extend range of 125-200mm.
An external M12x1.25 threaded stop with a lock nut mechanically limits how far the rod extends, allowing on-machine tuning without changing parts. The adjuster only changes the stroke length, so the force remains identical to a standard ACQ. The cylinder uses a fixed elastomer bumper for deceleration and the -S magnet works with reed or solid-state switches.
