Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X200-75B
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X200-75B 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 ACQJ32X200-75B
The ACQJ32X200-75B is a double-acting JIS compact cylinder built for applications requiring precise extend positioning. It features a 32mm bore and a 200mm full stroke, making it a long-stroke made-to-order variant since it exceeds the standard 100mm maximum for this bore size. An external M12x1.25 threaded stop with a lock nut limits the rod extension, providing a usable extend range of 125-200mm without changing parts. The retract stroke remains completely unaffected.
Because the adjuster only alters travel length and not piston area, output force stays identical to a standard ACQ of the same bore. You get 402.1N push and 301.6N pull at 0.5MPa. This male-rod (-B) version uses an M14x1.5 thread to couple directly to your load. It relies on a fixed NBR elastomer bumper at each end for end-of-stroke deceleration and includes sensor grooves, though this specific SKU ships without a magnet.
Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X200-75B Technical Specifications
| Model | Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X200-75B |

| 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 ACQJ32X200-75B Is Used
Machining Fixture Stops
Dial in the extend position of clamping arms on a CNC machining center during product changeovers, using the external stop to accommodate different part widths without swapping cylinders.
Sorting Diverter Arms
Adjust the reach of a diverter gate on a packaging conveyor line to handle varying box sizes, ensuring positive contact without repositioning the cylinder mount.
Press Fit Depth Control
Fine-tune the downward extend stroke on an assembly press to set precise insert depths for trial runs, preventing over-travel before committing to a fixed stop.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X200-75B the Right Cylinder?
Selecting this 32mm bore cylinder provides 562.9N of push force at 0.7MPa. If you need less force, stepping down to a 25mm bore yields 245.4N push at 0.5MPa, while moving up to a 40mm bore provides 628.3N push at 0.5MPa. A standard fixed-stroke ACQ is sufficient if your extend end position never requires adjustment. Confirm your ordering essentials: 32mm bore, 200mm full stroke, 75mm adjustable window, male M14x1.5 rod thread, and no magnet. Note that a plain cylinder does not hold its load on air loss; install an external rod lock or pilot-operated check valve for fail-safe holding.
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 ACQJ32X200-75B FAQ
This 32mm bore cylinder 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 200mm, and with the 75mm adjustment window, the usable extend range is 125-200mm. The retract stroke remains fixed at 200mm.
An external M12x1.25 threaded stop with a lock nut mechanically limits how far the rod extends, shortening the stroke without changing the piston area, so force remains identical to a standard ACQ. The cylinder uses fixed NBR elastomer bumpers at both ends for deceleration rather than adjustable air cushions. This specific model ships without a sensor magnet but retains body grooves for adding reed or solid-state switches.
