Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X125-75S
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X125-75S is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø160mm bore and 125mm full stroke. Turn the stop to fine-tune the end position on the machine without changing parts.

About the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X125-75S
The ACQJ160X125-75S is a double-acting JIS compact cylinder featuring a massive 160mm bore. An external M36x2.0 threaded stop and lock nut restricts the forward extend position, yielding a usable extension span of 50 to 125mm. The return stroke remains completely unaffected by this adjustment. Equipped with the -S magnet option, the integrated piston band works seamlessly with both reed and solid-state electronic switches for precise position sensing.
Because the adjuster solely alters travel length without modifying the piston face area, output force remains identical to a standard ACQ of this size. You get 10053.1N of push and 9424.8N of pull at 0.5MPa, scaling to 14074.3N push at 0.7MPa, with a maximum push capacity of 2050kgf at 1.0MPa. Deceleration relies on fixed NBR elastomer bumpers at both ends rather than adjustable air cushions, meaning external shock absorbers are recommended for high-energy loads.

| Adjuster thread | M36×2.0 |
| Port size | PT3/8 |
| 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 | M24×3.0 (F) / M36×1.5 (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 (Ø160mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 10053 N | 9425 N |
| 0.7 MPa | 14074 N | — |
| Max (@1.0 MPa) | 2050 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 ACQJ125~160 Adjustable Compact Cylinder ACQJ160X125-75S Is Used
Press Tooling Changeover
Adapt heavy stamping or press fixtures rapidly by dialing the extend stop between 50 and 125mm, accommodating varying material thicknesses without swapping mechanical spacers.
Large Assembly Presses
Dial in exact insertion depths for large automotive or appliance components on the machine floor, using the fixed NBR bumpers to handle the end-of-stroke impact.
Pallet Positioning Stops
Set precise end stops for heavy-duty pallet lifts or indexing conveyors, tweaking the rod extension in place to align with different pallet dimensions.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X125-75S the Right Cylinder?
Choosing this 160mm bore provides immense thrust when 0.5MPa yields 10053.1N push. If you need less force, dropping to the 140mm bore lowers push to 7696.9N, while stepping outside this big-bore compact series to a 100mm unit cuts push to 3927.0N. A fixed-stroke ACQ is sufficient if your end position never varies, but the ACQJ external stop is essential for product-changeover tasks. When ordering, verify the 125mm full stroke, the 75mm window, the -S magnet, PT3/8 port, and the default female M24x3.0 rod-end thread. Note that a plain cylinder drifts on air loss; add an external rod lock for fail-safe load holding.
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 ACQJ125~160 Adjustable Compact Cylinder ACQJ160X125-75S FAQ
This cylinder delivers 10053.1N push and 9424.8N pull at 0.5MPa, 14074.3N push at 0.7MPa, and a maximum push of 2050kgf at 1.0MPa. The full stroke is 125mm with a 75mm adjustment window, allowing the extend stroke to be fine-tuned anywhere from 50mm to 125mm.
The external M36x2.0 threaded stop changes only the extend stroke length; it does not alter piston area, so force remains identical to a standard ACQ. The cylinder uses fixed elastomer bumpers for end-of-stroke deceleration rather than adjustable air cushions, so external shock absorbers are advised for high-speed approaches.
