Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X200-50
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X200-50 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 ACQJ32X200-50
This double-acting single-rod JIS compact cylinder features an external threaded stop with a lock nut that limits the EXTEND end position. You can fine-tune the extend travel on the machine across a 150-200mm usable range (the 200mm full stroke minus up to a 50mm window) without swapping parts. The RETRACT stroke remains completely unaffected. Because the piston area is unchanged, the output force equals a standard ACQ of the same bore.
As a long-stroke made-to-order variant, the 200mm stroke exceeds the 100mm standard maximum for a 32mm bore, extending into the 100-300mm long-stroke range. It includes a fixed NBR elastomer bumper at each end for end-of-stroke deceleration rather than an adjustable air cushion. The body features magnetic-switch grooves, though this specific unit ships without a magnet. Operating pressure is 0.15-1.0 MPa, and the PT1/8 port pairs with a 16mm rod.

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 ACQJ32X200-50 Is Used
Machining Fixture Clamps
Dial in the exact clamping reach on a CNC fixture during product-changeover, shortening the extend stroke from 200mm down to 150mm to accommodate different part heights.
Adjustable Transfer Stops
Act as a diverter or end-stop on a packaging conveyor, where the external lock nut allows operators to tweak the extended stop position for varying carton lengths on the fly.
Assembly Press Positioning
Establish trial end positions on an assembly press, testing insertion depths precisely on the machine before locking the M12x1.25 adjuster thread for production runs.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X200-50 the Right Cylinder?
When sizing this actuator, the 32mm bore yields 402.1N of push force at 0.5 MPa. Stepping down to a 25mm bore drops the push force to 245.4N, while stepping up to a 40mm bore increases it to 628.3N. If your application never requires end-position adjustments, a fixed-stroke ACQ cylinder suffices. To order this adjustable version correctly, confirm the 32mm bore, 200mm full stroke, 50mm window, female M8x1.25 rod-end thread, and PT1/8 porting.
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 ACQJ32X200-50 FAQ
It provides 402.1N push and 301.6N pull force at 0.5 MPa, 562.9N push at 0.7 MPa, and a maximum push force of 82kgf at 1.0 MPa. The usable extend range is 150-200mm (the 200mm full stroke minus up to a 50mm window).
No. The external stop limits the extend stroke length only, leaving the retract stroke unaffected. Because the piston area remains the same, the output force is identical to a standard ACQ. The unit relies on a fixed elastomer bumper for deceleration and does not hold loads on air loss.
