Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X125-20S
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X125-20S is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø160mm bore and 125mm 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 ACQJ160X125-20S
The ACQJ160X125-20S is a big-bore JIS compact pneumatic cylinder featuring a double-acting single rod and an external extend stop. A threaded screw with a lock nut restricts forward travel, providing a usable extend range of 105-125 mm from the 125 mm full stroke. Retraction remains completely unaffected.
Because the piston area stays constant, output force equals a standard ACQ, delivering 10053.1 N push at 0.5 MPa. The Ø40 mm rod uses an M36x2.0 adjuster thread, and the -S magnet enables tracking with reed or solid-state switches. Fixed NBR elastomer bumpers absorb end-of-stroke impact instead of adjustable air cushions.

| Model | Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X125-20S |
|---|---|
| Series | ACQJ JIS compact adjustable-stroke cylinder |
| Bore size | Ø160 mm |
| Full stroke | 125 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 ACQJ160X125-20S Is Used
Heavy Press Setup
Dial in the exact 105-125 mm forward clamp position on large metal forming presses during initial tool setup without machining custom spacers.
Product Changeover
Rapidly adapt the end stop in automated woodworking machinery when switching between thick and thin material profiles on the fly.
Trial End Positions
Test varying extend depths on large injection molding unloaders to find the optimal pick point before finalizing the mechanical layout.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X125-20S the Right Cylinder?
This 160 mm bore generates 10053.1 N forward thrust at 0.5 MPa, sitting below the 125 mm bore (6135.9 N) and representing the top big-bore compact option. Choose it for high-force tasks needing exact forward positioning. If the 125 mm full stroke is always constant, a fixed ACQ cylinder suffices. Confirm the 20 mm adjustment window, -S magnet, and female M24x3.0 rod end 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 ACQJ160X125-20S 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 usable extend range is 105-125 mm (125 mm full stroke minus a 20 mm window).
The external M36x2.0 threaded stop with lock nut limits forward travel only, so force remains identical to a standard ACQ. Fixed NBR bumpers decelerate the load near stroke end. A plain cylinder will not hold a load on air loss; use an external rod lock for fail-safe positioning.
