Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X175-20S
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X175-20S is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø160mm bore and 175mm 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 ACQJ160X175-20S
The AirTAC ACQJ160X175-20S is a double-acting JIS compact cylinder featuring an external threaded stop and lock nut to fine-tune the extend end position on your machinery. With a 175mm full stroke and a 20mm adjustment window, the usable extend range spans 155 to 175mm. The retract stroke remains completely unaffected by this mechanism.
Delivering identical force to a standard ACQ of this size, the 160mm bore generates 10053.1N push and 9424.8N pull at 0.5 MPa. The piston rod measures 40mm with an M24x3.0 female thread, while the M36x2.0 external adjuster handles stroke limiting. Fixed NBR elastomer bumpers absorb impact at both ends, and the integrated -S magnet interfaces with reed or solid-state switches.

| 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 ACQJ160X175-20S Is Used
Heavy Press Tonnage
Dialing in the exact 155-175mm extend reach on a large stamping press to accommodate varying material thicknesses without machining new spacers.
Automated Welding Fixtures
Adjusting the clamp end-point on the fly during automotive body-in-white assembly to adapt to different vehicle model chassis geometries.
Pallet Lift Positioning
Fine-tuning the raise height on heavy-load palletizers to interface smoothly with varying conveyor elevations or oversized product heights.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X175-20S the Right Cylinder?
Selecting this 160mm bore provides massive output, yielding 14074.3N push at 0.7 MPa and a maximum 2050 kgf at 1.0 MPa. If your application requires slightly less force, stepping down to a 140mm bore yields 7696.9N push at 0.5 MPa, whereas moving up is impossible as this is the largest big-bore compact option available up to 300mm standard stroke. If exact end positioning is never required after initial setup, a fixed-stroke ACQ cylinder suffices. When ordering, confirm the 175mm full stroke, 20mm window, -S magnet, and female rod thread.
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 ACQJ160X175-20S FAQ
This cylinder delivers 10053.1N push and 9424.8N pull at 0.5 MPa, 14074.3N push at 0.7 MPa, and a maximum push of 2050 kgf at 1.0 MPa. The full stroke is 175mm with a 20mm adjustment window, allowing the extend stroke to be set anywhere from 155mm to 175mm.
The M36x2.0 external threaded stop with lock nut mechanically limits the extend length without altering piston area, so force remains identical to a standard ACQ. Fixed NBR bumpers decelerate the rod near stroke ends, but a plain cylinder does not hold its load on air loss; for fail-safe holding, install an external rod lock or pilot-operated check valve.
