Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X200-75S
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X200-75S is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø40mm 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 ACQJ40X200-75S
The AirTAC ACQJ40X200-75S is a double-acting, JIS compact pneumatic cylinder featuring an external threaded stop and lock nut that limits the extend end position. This long-stroke made-to-order variant provides a total stroke of 200mm with a 75mm adjustment window, allowing the usable extend range to be fine-tuned anywhere between 125mm and 200mm directly on your equipment. The retract stroke remains completely unaffected by this mechanism.
Because the adjustment only restricts travel length and leaves piston area unchanged, output force is identical to a standard ACQ of the same bore. At 0.5 MPa you get 628.3 N of push force and 527.8 N of pull force. The bore 40 body includes fixed NBR elastomer bumpers at both ends for end-of-stroke deceleration, and the integrated -S piston magnet supports position sensing with either reed or electronic solid-state switches.

| 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 |

| 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 (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 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 ACQJ40X200-75S Is Used
Machining Fixture Clamping
Dial in the exact clamping reach on a CNC machining fixture across 125-200mm without fabricating custom spacer blocks for varying part heights.
Product Changeover Diverter
Rapidly reposition a conveyor sorting diverter stop during packaging line product changeovers by simply turning the external M12x1.25 adjuster nut.
Assembly Press Stroke Setup
Establish safe trial end positions on an automated assembly press, preventing over-travel and tool damage during new component run-in.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X200-75S the Right Cylinder?
When sizing this 40mm bore, dropping down to a 32mm bore yields 402.1 N push at 0.5 MPa, while stepping up to a 50mm bore provides 981.8 N push. If your extend endpoint is permanently fixed and never requires tweaking, a standard non-adjustable ACQ cylinder will suffice. To order this adjustable version correctly, confirm the 40mm bore, the 200mm full stroke, the 75mm window, the -S magnet option, and your required rod-end thread (default female M8x1.25). Keep in mind this 200mm stroke is a long-stroke configuration, exceeding the 100mm standard maximum for this bore size.
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 ACQJ40X200-75S FAQ
This 40mm bore cylinder delivers 628.3 N push and 527.8 N pull at 0.5 MPa, 879.6 N push at 0.7 MPa, and a maximum push of 128 kgf at 1.0 MPa. It features a 200mm full stroke with a 75mm adjustable window, providing a usable extend range of 125-200mm.
The external M12x1.25 threaded stop limits only the extend travel distance, meaning the output force remains identical to a standard ACQ cylinder. End-of-stroke deceleration is handled by fixed NBR elastomer bumpers at both ends; for high-energy loads at long strokes, consider adding an external shock absorber or slowing the approach speed.
