Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X200-75SB
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X200-75SB 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 ACQJ32X200-75SB
The AirTAC ACQJ32X200-75SB is a double-acting, single-rod JIS compact cylinder built for adjustable extend strokes. An external M12x1.25 threaded stop and lock nut limits the outward travel. You can tune the usable extend range from 125mm up to the full 200mm directly on your equipment, while the retract stroke remains completely unaffected. Because the piston area stays constant, output force equals a standard ACQ of the same bore. This unit delivers a push force of 402.1N at 0.5MPa and 562.9N at 0.7MPa.
As a long-stroke variant, this 200mm model exceeds the 100mm standard maximum for the 32mm bore, making it a made-to-order solution for applications needing extended reach. The unit includes a male M14x1.5 piston rod end (-B) that couples directly to your load, and a built-in magnet (-S) for position sensing. It operates at pressures from 0.15 to 1.0MPa and relies on fixed NBR elastomer bumpers at each end for deceleration. Note that a plain compact cylinder drifts on air loss; use an external rod lock or pilot-operated check valve if you require fail-safe load holding.

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 ACQJ32X200-75SB Is Used
Machining Center Changeover
Dial in the extend stop during product changeover on a CNC fixture, shifting the 125 to 200mm outward travel to match new part depths without machining new spacers.
Conveyor Sorting Diverter
Set precise diversion points on a packaging line by adjusting the external stop, allowing rapid reconfiguration for varying box sizes on the fly.
Assembly Press Testing
Probe trial end positions on an assembly press by tweaking the lock nut, finding the exact contact pressure before committing to a fixed final stroke length.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X200-75SB the Right Cylinder?
If you need less force, the adjacent 25mm bore yields a 245.4N push at 0.5MPa. For heavier drives, step up to the 40mm bore, which provides a 628.3N push at 0.5MPa. If your machine design never requires stroke adjustments, a fixed-stroke ACQ cylinder will suffice. When ordering this unit, verify the 32mm bore, 200mm full stroke, 75mm adjuster window, the -S magnet for electronic or reed switches, and the -B male rod thread.
Quick checklist

- ✓ 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 ACQJ32X200-75SB FAQ
This long-stroke cylinder has a 200mm full stroke with a 75mm adjustable window, giving a usable extend range of 125 to 200mm. It generates a push force of 402.1N and a pull force of 301.6N at 0.5MPa, 562.9N push at 0.7MPa, and a maximum push of 82kgf at 1.0MPa.
The external M12x1.25 threaded stop with lock nut physically limits how far the rod extends, shortening the outward stroke without changing the piston area, so force remains identical to a standard ACQ. The cylinder uses fixed NBR elastomer bumpers at each end for deceleration rather than adjustable air cushions, and the -S magnet works with reed or solid-state electronic switches.
