Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X125-10S
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X125-10S 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 ACQJ160X125-10S
The AirTAC ACQJ160X125-10S represents the big-bore JIS compact series, featuring a double-acting single rod and a 125mm full stroke. An external M36x2.0 threaded stopper with a lock nut restricts forward travel, yielding a usable extend range of 115 to 125mm. You simply dial in the end position directly on the machinery. The return journey remains completely unaffected.
Because the internal piston area stays constant, output force equals that of a regular ACQ counterpart. At 0.7 MPa this massive unit delivers 14074.3N of push force, peaking at 2050 kgf under 1.0 MPa. It incorporates fixed NBR elastomer bumpers at both ends rather than pneumatic cushions, and the integrated -S magnet interfaces with reed or solid-state switches.

| 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 ACQJ160X125-10S Is Used
Press Tooling Changeover
Dialing the external M36x2.0 stopper provides rapid depth adjustments when swapping heavy forming dies on a 160-ton press line.
Automotive Welding Stands
Fine-tune the electrode approach distance on the fly to accommodate various automotive subframe profiles without changing hardware.
Heavy Pallet Positioning
Modifying the 115-125mm extend window aligns massive 2050 kgf clamps for different pallet thicknesses in automated assembly cells.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X125-10S the Right Cylinder?
Selecting this Ø160mm unit means requiring immense thrust within a riveted body footprint. If your task needs less than 7696.9N push at 0.5 MPa, drop down to the Ø140 bore; if you need longer forward motion beyond 300mm, consider external tie-rod alternatives. A non-adjustable ACQ suffices when your end-stop never varies. Verify your ordering code encompasses the 125mm full stroke, 10mm window, -S magnet, and the default female M24x3.0 rod thread. Note that PT3/8 ports supply the air.
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 ACQJ160X125-10S FAQ
It generates 10053.1N push and 9424.8N pull at 0.5 MPa, or 14074.3N push at 0.7 MPa, with a maximum push capacity of 2050 kgf at 1.0 MPa. The 125mm full stroke includes a 10mm adjustable window, allowing an extend range of 115-125mm, while retract stroke remains fixed.
An external M36x2.0 threaded screw and lock nut mechanically limits forward travel, allowing on-machine tuning without swapping parts. This adjustment alters stroke length only; output force stays identical to a standard ACQ. Deceleration relies on fixed NBR elastomer bumpers at both ends, so for high kinetic energy loads, add external shock absorbers or slow the approach speed. Note that a plain ACQ cylinder will drift if air pressure is lost, so use an external rod lock for fail-safe load holding.
