Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X125-100S
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X125-100S 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 ACQJ160X125-100S
The AirTAC ACQJ160X125-100S is a big-bore JIS compact cylinder featuring a double-acting single rod and an external extend stop. A threaded adjuster with a lock nut limits the outward stroke, yielding a usable extend range of 25 to 125 mm from the 125 mm full stroke. Retract travel remains fixed at its original length. Because the piston area stays constant, 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, this unit handles heavy loads within the big-bore compact range supporting up to 300 mm strokes. The body integrates fixed NBR elastomer bumpers at each end rather than adjustable air cushions. Equipped with a magnet (-S), the cylinder operates seamlessly with either reed or electronic solid-state switches via its built-in grooves.
Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X125-100S Technical Specifications
| Model | Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X125-100S |
|---|---|
| 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 ACQJ160X125-100S Is Used
Heavy Press Tonnage Setup
Dial in the exact extend position during heavy press commissioning. The M36x2.0 external adjuster allows 25 to 125 mm outward travel without machining new spacers.
Automated Welding Changeover
Adapt large robotic welding fixtures for different vehicle frames. Shorten the extend stroke on the fly to accommodate varying part depths while maintaining 9424.8 N pull force.
Pallet Lift Height Tuning
Fine-tune the lift height on heavy-duty palletizers. The lock nut secures the 25-125 mm range precisely, while the fixed elastomer bumper absorbs impact at stroke end.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X125-100S the Right Cylinder?
Selecting this 160 mm bore provides massive thrust, pushing 14074.3 N at 0.7 MPa. If your application requires less force, stepping down to a 140 mm bore yields 7696.9 N push at 0.5 MPa; conversely, the 160 mm represents the maximum standard bore in this series. A fixed-stroke ACQ is sufficient if your end position never varies, but the ACQJ variant is essential for on-machine tuning. Confirm your ordering parameters: 160 mm bore, 125 mm full stroke, 100 mm adjuster window, magnet included (-S), and the default female M24x3.0 rod-end 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 ACQJ160X125-100S FAQ
This cylinder delivers a push force of 10053.1 N and a pull force of 9424.8 N at 0.5 MPa, and 14074.3 N push at 0.7 MPa. The maximum push is 2050 kgf at 1.0 MPa. The usable extend range is 25 to 125 mm, created by the 100 mm adjustment window subtracted from the 125 mm full stroke.
The external threaded stop with a lock nut limits only the extend stroke; force remains identical to a standard ACQ because the piston area is unchanged. It uses fixed elastomer bumpers rather than adjustable air cushions. Note that a plain compact cylinder does not hold its load on air loss or when a valve is centered, so an external rod lock or pilot-operated check valve is required for fail-safe holding.
