Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X75-75S
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X75-75S is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø160mm bore and 75mm 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 ACQJ160X75-75S
The AirTAC ACQJ160X75-75S is a double-acting, JIS compact cylinder featuring a 160 mm bore and an external extend stop. A threaded rod with a lock nut lets you fine-tune the forward end position directly on the machine. With a 75 mm full stroke and a 75 mm window, the usable extend range is 0-75 mm. The return stroke remains completely unaffected by this adjustment.
Because the piston area stays constant, output force equals a standard ACQ of this size. You get 10053.1 N push and 9424.8 N pull at 0.5 MPa. The unit includes a -S piston magnet compatible with reed or solid-state sensors, fixed NBR elastomer bumpers, and a PT3/8 port. As a big-bore compact design, it supports up to 300 mm of travel.

| Bore size | Ø160 mm |
| Full stroke | 75 mm |
| 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 ACQJ160X75-75S Is Used
Heavy Press Tonnage Tuning
Dial in the exact extend contact point on a large metal-forming press during tooling setup, preventing over-travel without machining new spacers.
Pallet Lift Height Calibration
Adjust the lift height on automated conveyor pallet stops to match varying product thicknesses, using the external thread to set the exact 0-75 mm reach.
Large Fixture Positioning
Secure heavy automotive machining fixtures by tweaking the clamping reach on the fly, accommodating part variations while maintaining 9424.8 N pull force.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X75-75S the Right Cylinder?
This 160 mm bore provides 10053.1 N push at 0.5 MPa. If your application requires less force, the 140 mm bore yields 7696.9 N push. If you need more power, this is the largest bore in the ACQJ family, delivering a maximum 2050 kgf push at 1.0 MPa. Choose this adjustable model only if your fixture setup or product changeover requires frequent end-position tuning; a fixed-stroke ACQ is simpler if the travel never varies. Confirm your ordering code by specifying the 75 mm stroke, the 75 mm window, the -S magnet, and the default female M24x3.0 rod end.
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 ACQJ160X75-75S FAQ
The window is 75 mm, yielding a usable extend range of 0-75 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 external M36x2.0 threaded stop with a lock nut limits the extend stroke; it changes travel length only, not force. The cylinder uses fixed NBR elastomer bumpers, not adjustable air cushions. For high energy, add an external shock absorber. Note that a plain ACQ does not hold loads on air loss; use an external rod lock for fail-safe holding.
