The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ140X200-100S is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø140mm bore and 200mm full stroke. Turn the stop to fine-tune the end position on the machine without changing parts.
The AirTAC ACQJ140X200-100S is a double-acting JIS compact cylinder engineered for big-bore tasks, featuring a 140mm bore and a 200mm full stroke. An external M27x2.0 threaded stop with a lock nut restricts the extend end position, yielding a usable forward range of 100 to 200mm. This permits precise on-machine end-position tuning without swapping parts, while the retract stroke remains completely unaffected.
Because the adjuster solely limits travel and not the piston area, output force stays identical to a standard ACQ of this size. You get 7696.9N push and 7294.8N pull at 0.5MPa, scaling to 10775.7N push at 0.7MPa, with a 1570kgf maximum at 1.0MPa. The design incorporates a fixed NBR elastomer bumper at each end for end-of-stroke deceleration and includes a built-in magnet (-S) for tracking with reed or solid-state switches.

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.
| 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.

Dial in the exact forming depth on large pneumatic presses during initial tooling setup, using the external stop to test trial end positions before finalizing the mechanical hard stop.
Accommodate varying fixture heights on automotive welding lines by adjusting the extend stroke within the 100mm window, enabling rapid product changeover without replacing the actuator.
Fine-tune the raised discharge height of heavy material lifts in packaging conveyors, allowing operators to match varying pallet sizes or machine interfaces directly on the floor.
Selecting this 140mm bore unit means requiring substantial force alongside adaptable reach. If 7696.9N push at 0.5MPa is excessive, stepping down to a 125mm bore yields 6135.9N; conversely, escalating to a 160mm bore provides 10053.1N. If your application never requires altering the forward endpoint, a fixed-stroke ACQ cylinder suffices and simplifies setup. When ordering the ACQJ140X200-100S, verify the 200mm full stroke, the 100mm adjuster window, the -S magnet option, and the default female M22x2.5 rod-end thread alongside the PT3/8 port size.
Quick checklist
This model delivers 7696.9N push and 7294.8N pull at 0.5MPa, 10775.7N push at 0.7MPa, and a maximum push of 1570kgf at 1.0MPa. The full stroke is 200mm with a 100mm adjustment window, resulting in a usable extend range of 100 to 200mm.
The M27x2.0 external threaded stop and lock nut mechanically limit the extend distance without altering the piston area, meaning force remains identical to a standard ACQ. The cylinder uses fixed NBR bumpers for deceleration, but it does not hold loads on air loss; for fail-safe holding, install an external rod lock or pilot-operated check valve.
