Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ140X125-10S
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ140X125-10S is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø140mm 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 ACQJ140X125-10S
The ACQJ140X125-10S is a double-acting JIS compact cylinder featuring a 140mm bore and a 125mm full stroke. An external M27x2.0 threaded stop with a lock nut limits the extend end position, yielding a usable forward range of 115 to 125mm. Retract travel remains completely unaffected. Because the piston area stays constant, output force equals a standard ACQ of this size.
This big-bore variant delivers 7696.9N push and 7294.8N pull at 0.5MPa, peaking at 1570 kgf maximum push at 1.0MPa. The body uses fixed NBR elastomer bumpers at each end rather than adjustable air cushions. Equipped with a built-in piston magnet (-S), it supports both reed and electronic solid-state sensors. Operating pressure spans 0.15 to 1.0MPa, and the PT3/8 port feeds a 32mm rod with a female M22x2.5 end thread.

| Series | ACQJ JIS compact adjustable-stroke cylinder |
| Bore size | Ø140 mm |
| Full stroke | 125 mm |
| Adjuster thread | M27×2.0 |
| 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 | M22×2.5 (F) / M30×1.5 (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 (Ø140mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 7697 N | 7295 N |
| 0.7 MPa | 10776 N | — |
| Max (@1.0 MPa) | 1570 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 ACQJ140X125-10S Is Used
Press Tonnage Calibration
Dial in the exact 115-125mm extend stop on a heavy stamping press to test tonnage limits without swapping mechanical spacers.
Large Weldment Positioning
Fine-tune the forward clamp position during automotive chassis fixturing to accommodate varying metal panel tolerances.
Pallet Lift Height Setup
Adjust the extend endpoint on a heavy-duty pallet lift to match varying load heights, ensuring gentle contact via the fixed elastomer bumper.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ140X125-10S the Right Cylinder?
Selecting this 140mm bore provides massive thrust in a compact footprint. If your application requires less force, stepping down to the 125mm bore yields 6135.9N push at 0.5MPa, whereas moving up to the 160mm bore provides 10053.1N push. A fixed-stroke ACQ cylinder suffices if your end position never varies. Confirm your ordering essentials: 140mm bore, 125mm full stroke, 10mm adjuster window, magnet option S, and female M22x2.5 rod 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 ACQJ140X125-10S FAQ
It delivers 7696.9N push and 7294.8N pull at 0.5MPa, 10775.7N push at 0.7MPa, and a maximum push of 1570 kgf at 1.0MPa. The usable extend range is 115-125mm (a 10mm adjustment window), while the retract stroke remains fixed at 125mm.
No, the adjuster changes stroke length only, leaving piston area and force identical to a standard ACQ. The cylinder relies on fixed NBR elastomer bumpers at each end for deceleration rather than adjustable air cushions. Note that a plain cylinder does not hold its load on air loss; use an external rod lock for fail-safe holding.
