Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X200-75
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X200-75 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 ACQJ32X200-75
The AirTAC ACQJ32X200-75 is a double-acting JIS compact cylinder built as a long-stroke made-to-order variant, extending the standard 100mm maximum up to 200mm. It features an external M12x1.25 threaded stop with a lock nut that limits the extend end position. You get a usable extend range of 125-200mm, while the retract stroke remains completely unaffected.
Because the piston area is unchanged, output force stays identical to a standard ACQ of this bore, delivering 402.1N push and 301.6N pull at 0.5MPa. The body uses a fixed NBR elastomer bumper at each end rather than an adjustable air cushion, and includes sensor grooves, though this specific SKU ships without a magnet.

| 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 ACQJ32X200-75 Is Used
Machining Fixture Stops
Dial in the extend position on CNC machining fixtures during product-changeover, saving time by avoiding mechanical part swaps.
Sorting Diverter Arms
Adjust the pusher depth on packaging lines to handle varying carton sizes without reprogramming the machine logic.
Assembly Press Tacking
Set trial end positions on automated assembly presses to test engagement depths before finalizing a hard mechanical stop.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X200-75 the Right Cylinder?
When sizing this unit, stepping down to a 25mm bore yields 245.4N push, whereas moving up to a 40mm bore provides 628.3N push at 0.5MPa. If your extend end position never varies, a fixed-stroke ACQ cylinder is simpler and avoids the external adjuster hardware. To order correctly, confirm the 32mm bore, 200mm full stroke, 75mm window, female M8x1.25 rod end, and whether you require the S magnet option for electronic or reed switches.
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 ACQJ32X200-75 FAQ
It provides 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 with a 75mm window, yielding an adjustable extend range of 125-200mm.
The M12x1.25 threaded stop with lock nut mechanically limits the extend length, so force remains identical to a standard ACQ. The cylinder uses fixed NBR bumpers for end-of-stroke deceleration, but a plain ACQ will drift on air loss, requiring an external rod lock for fail-safe holding.
