Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X200-20S
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X200-20S 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 ACQJ32X200-20S
The AirTAC ACQJ32X200-20S is a double-acting, single-rod JIS compact cylinder built for applications requiring precise extend positioning. Featuring a 32mm bore and a 200mm stroke, this long-stroke variant is manufactured to order, exceeding the standard 100mm maximum for this bore size. An external M12x1.25 threaded stop and lock nut mechanism allows you to fine-tune the extend end position on the machine without swapping components. The usable extend range spans 180 to 200mm, while the retract stroke remains completely unaffected.
Because the adjuster only limits travel length, the piston area stays the same, meaning output force is identical to a standard ACQ of this size. At 0.5 MPa, it delivers 402.1N of push force and 301.6N of pull force. The body incorporates magnetic-switch grooves, and the included -S piston magnet is fully compatible with both reed and electronic solid-state sensors. Deceleration is handled by fixed NBR elastomer bumpers at each end rather than adjustable air cushions.

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 ACQJ32X200-20S Is Used
Variable Gauge Stops
Dial in exact extend distances from 180 to 200mm on packaging machines that process varying carton widths, enabling rapid product changeover without mechanical rebuilds.
Trial End Positions
Perfect for prototype assembly stations where the final extend stop coordinate is unknown, allowing technicians to tweak the M12x1.25 adjuster screw until the optimal tool contact point is found.
Long-Reach Clamping
Securely clamp parts in automated welding fixtures requiring a 200mm reach, relying on the 402.1N push force while backing off the stroke slightly to accommodate different material thicknesses.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X200-20S the Right Cylinder?
Selecting this 32mm bore actuator involves matching your force and travel requirements; it provides 402.1N push at 0.5 MPa. If your application needs less force, the next size down (25mm bore) yields 245.4N push, whereas stepping up to a 40mm bore provides 628.3N. A fixed-stroke standard ACQ cylinder is sufficient if you do not need end-position tuning. Note that the 200mm stroke makes this a made-to-order long-stroke unit. When ordering, confirm the 32mm bore, 200mm full stroke, 20mm adjuster window, the -S magnet option, and the default female M8x1.25 rod-end thread. The port size is PT1/8.
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 ACQJ32X200-20S FAQ
This 32mm bore cylinder delivers 402.1N push and 301.6N pull at 0.5 MPa, 562.9N push at 0.7 MPa, and a maximum push of 82 kgf at 1.0 MPa. The full stroke is 200mm, but the external M12x1.25 threaded stop provides a 20mm adjustment window, allowing the usable extend range to be set anywhere from 180 to 200mm. The retract stroke remains unaffected.
No, the adjuster changes only the extend travel length, not the piston area, so the output force remains identical to a standard ACQ of the same bore. Deceleration is managed by fixed NBR elastomer bumpers at both ends rather than adjustable air cushions. For high-speed or high-energy loads, adding an external shock absorber is recommended. Additionally, the -S magnet works with reed or solid-state switches, but note that a plain cylinder will not hold its load on air loss without an external rod lock.
