Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X200-75
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X200-75 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 ACQJ40X200-75
The AirTAC ACQJ40X200-75 is a double-acting, JIS compact cylinder engineered as a long-stroke, made-to-order variant. It features an external threaded stop with a lock nut on the rod-end side, allowing you to precisely limit how far the rod extends. The usable extend range spans 125 to 200 mm, while the retract stroke remains completely unaffected. Because the piston area is unchanged, the output force is identical to a standard ACQ of this bore.
This 40 mm bore unit delivers 628.3 N of push force and 527.8 N of pull force at 0.5 MPa. It incorporates a fixed NBR elastomer bumper at each end for end-of-stroke deceleration rather than an adjustable air cushion. The body includes magnetic-switch grooves, though this specific configuration ships without a magnet. Operating speed ranges from 30 to 500 mm/s, and the PT1/8 port ensures reliable pneumatic supply.

| 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 ACQJ40X200-75 Is Used
Variable Depth Drilling
Dial in the exact drilling depth on multi-product machining fixtures by turning the external M12x1.25 stopper screw, avoiding the need to swap out cylinder bodies for different material thicknesses.
Package Changeover Diverter
Adjust the extend stroke on the fly when transitioning between varying carton sizes on a packaging line, ensuring the diverter gate meets exact positioning requirements without mechanical rebuilds.
Prototype Press Stops
Safely test new end positions on a light assembly press by limiting the extend stroke to 125 mm initially, then gradually increasing the window up to the full 200 mm as the process is validated.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X200-75 the Right Cylinder?
Selecting this 40 mm bore model provides 628.3 N push at 0.5 MPa. If your application requires less force, the adjacent 32 mm bore yields 402.1 N push, whereas stepping up to a 50 mm bore provides 981.8 N. If your extend position never varies, a fixed-stroke ACQ cylinder suffices. When ordering, confirm the 40 mm bore, the 200 mm full stroke, the 75 mm adjustment window, the female M8x1.25 rod thread, and the PT1/8 porting. Remember that this is a long-stroke variant exceeding the 100 mm standard maximum for this bore.
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 ACQJ40X200-75 FAQ
This 40 mm bore cylinder provides 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. The full stroke is 200 mm with a 75 mm adjustment window, yielding a usable extend range of 125-200 mm. The retract stroke is unaffected by the adjuster.
The external M12x1.25 threaded stop with a lock nut limits only the extend stroke length, meaning the output force remains identical to a standard ACQ cylinder. Deceleration is handled by a fixed NBR elastomer bumper at each end, not an adjustable air cushion. Note that this model ships without a sensor magnet, and a plain pneumatic cylinder will not hold its load on air loss without an external rod lock.
