Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X40-40S
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X40-40S is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø160mm bore and 40mm 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 ACQJ160X40-40S
The AirTAC ACQJ160X40-40S is a double-acting JIS compact cylinder featuring a 160 mm bore and an external threaded stop with a lock nut. This mechanism limits the extend end position, providing a usable forward range of 0-40 mm from a 40 mm full stroke. The retract movement remains completely unaffected. Built-in piston magnet (-S) enables compatibility with reed or electronic solid-state switches.
Because the adjuster alters stroke length only, the output force is identical to a standard ACQ of this size, yielding 10053.1 N push and 9424.8 N pull at 0.5 MPa. The unit uses a PT3/8 port, a 40 mm rod, and an M36x2.0 adjuster thread. Fixed NBR elastomer bumpers absorb impact at both ends, while the big-bore compact body supports strokes up to 300 mm.

| Model | Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X40-40S |
|---|---|
| Series | ACQJ JIS compact adjustable-stroke cylinder |
| Bore size | Ø160 mm |
| Full stroke | 40 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 |
| Temperature | -20 to +70 °C |
| 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 ACQJ160X40-40S Is Used
Heavy Press Tuning
Dial in the exact 0-40 mm extend stop on a heavy-duty press without swapping parts during product-changeover.
Large Fixture Positioning
Adjust the extend limit on the fly for varying large-scale assembly fixtures requiring 14074.3 N push at 0.7 MPa.
Pallet Lift Stops
Fine-tune the lift height on heavy pallet handling machines where the fixed NBR bumper decelerates the 2050 kgf max load.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X40-40S the Right Cylinder?
This 160 mm bore provides 10053.1 N push at 0.5 MPa, sitting at the top of the range, so sizing down requires the 140 mm bore (7696.9 N push). If exact end positions are not needed, a fixed-stroke ACQ suffices. Confirm the 40 mm full stroke, 40 mm window, -S magnet, and female M24x3.0 rod thread when ordering.
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 ACQJ160X40-40S FAQ
It delivers 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 40 mm with a 40 mm adjustable window, giving a usable extend range of 0-40 mm.
The M36x2.0 threaded stop with lock nut limits only the extend length, leaving retract unaffected. Force is identical to a standard ACQ because piston area is unchanged. The fixed NBR bumper decelerates movement near stroke end, but a plain ACQ does not hold its load on air loss; use an external rod lock or pilot-operated check valve for fail-safe holding.
