Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X200-75S
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X200-75S is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø160mm bore and 200mm 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 ACQJ160X200-75S
The AirTAC ACQJ160X200-75S is a JIS compact, double-acting single-rod cylinder from the big-bore range, featuring an external threaded stop with a lock nut to limit the extend end position. You can fine-tune the usable extend travel from 125 mm up to the full 200 mm stroke directly on your machine without swapping parts, while the retract stroke remains unaffected. It includes a built-in piston magnet (-S) for positioning feedback.
Because the piston area stays the same, output force is identical to a standard ACQ of this bore, delivering 10053.1 N push and 9424.8 N pull at 0.5 MPa. The unit uses a PT3/8 port, a Ø40 mm rod with an M24x3.0 female rod-end thread, and an M36x2.0 external adjuster thread. Deceleration is handled by a fixed NBR elastomer bumper at each end, not an adjustable air cushion.

| 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 ACQJ160X200-75S Is Used
Press Tonnage Setup
Dial in the exact 125 to 200 mm extend position during heavy press tooling setup without machining custom spacers.
Automotive Welding Line
Adjust the extend stop on the fly for product-changeover when switching between different chassis subframe widths.
Palletizing Trial Stops
Test trial end positions for large pack sizes on a palletizer, securely locking the M36x2.0 adjuster nut once the ideal reach is found.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X200-75S the Right Cylinder?
If your application requires less thrust, the adjacent Ø140 bore provides 7696.9 N push at 0.5 MPa, whereas stepping up is not possible as this is the largest big-bore compact option. If you never need to alter the extend length, a fixed-stroke ACQ cylinder is simpler and sufficient. When ordering this adjustable version, confirm the 160 mm bore, 200 mm full stroke, 75 mm window, magnet option, 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 ACQJ160X200-75S FAQ
It provides 10053.1 N push and 9424.8 N pull at 0.5 MPa, 14074.3 N push at 0.7 MPa, and a maximum push of 2050 kgf at 1.0 MPa. The full stroke is 200 mm with a 75 mm adjustable window, giving a usable extend range of 125-200 mm.
No, the external M36x2.0 threaded stop only changes the extend length, not the piston area, so force remains identical to a standard ACQ. The cylinder uses fixed elastomer bumpers for deceleration and will drift on air loss, so an external rod lock or pilot-operated check valve is needed for fail-safe load holding.
