Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X175-30S
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X175-30S 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 ACQJ160X175-30S
The AirTAC ACQJ160X175-30S represents the big-bore JIS compact series, integrating a double-acting single rod with an external extend-limiting mechanism. A threaded stop screw and lock nut on the rod-end side lets you fine-tune the forward end position directly on the machine. With a 175 mm base stroke and a 30 mm reduction window, the usable extend range spans 145 to 175 mm, while the retract stroke remains completely unaffected.
Because the piston area is unchanged, output force stays identical to a standard ACQ of this bore, yielding 10053.1 N push and 9424.8 N pull at 0.5 MPa. The Ø40 mm piston rod uses an M24x3.0 female end thread, and the external adjuster features an M36x2.0 thread. Fixed NBR elastomer bumpers handle end-of-travel deceleration, and the included -S piston magnet supports both reed and solid-state electronic switches via the body grooves.

| 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 ACQJ160X175-30S Is Used
Press Tonnage Trials
Dial in the exact 145 to 175 mm extend position during heavy press commissioning without swapping cylinders, allowing precise gap adjustments for varying material thicknesses.
Large Fixture Changeover
Adapt heavy manufacturing lines quickly by shifting the end stop to accommodate new product dimensions, reducing tooling setup time between different production runs.
Heavy Lift Calibration
Test and set precise upper end positions for heavy lifting platforms on the fly, ensuring the fixed NBR bumpers contact exactly at the desired 145 mm shortened travel point.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X175-30S the Right Cylinder?
For 0.5 MPa push requirements below 7696.9 N, step down to the Ø140 bore; if your application demands more than 14074.3 N at 0.7 MPa, no larger compact body exists in this family. If your setup never requires on-the-fly end-position shifts, a fixed-stroke ACQ cylinder is simpler and entirely sufficient. When ordering this adjustable variant, verify the 160 mm bore, 175 mm full stroke, 30 mm window, the -S magnet for sensing, and the default 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 ACQJ160X175-30S FAQ
The usable extend range is 145 to 175 mm (a 175 mm base stroke shortened by up to 30 mm). Force is identical to a standard ACQ: push is 10053.1 N and pull is 9424.8 N at 0.5 MPa, push is 14074.3 N at 0.7 MPa, and max push is 2050 kgf at 1.0 MPa.
An M36x2.0 external threaded stop with a lock nut limits the extend stroke only; retract is unaffected and force is unchanged. Fixed NBR bumpers decelerate the load near stroke ends, but a plain ACQ body does not hold the load on air loss—use an external rod lock or pilot-operated check valve for fail-safe holding.
