The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ140X100-10S is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø140mm bore and 100mm full stroke. Turn the stop to fine-tune the end position on the machine without changing parts.
The AirTAC ACQJ140X100-10S is a big-bore JIS compact, double-acting single-rod cylinder featuring an external threaded stop and lock nut to limit the extend end position. You can fine-tune the usable extend stroke anywhere from 90 mm up to the full 100 mm directly on your machinery, while the retract stroke remains completely unaffected. Because the piston area stays constant, output force equals a standard ACQ of this exact size.
Delivering 7696.9 N push and 7294.8 N pull at 0.5 MPa, this unit uses a 32 mm rod and PT3/8 porting. The body integrates fixed elastomer NBR bumpers at each end rather than adjustable air cushions, and the -S suffix provides a built-in piston magnet compatible with reed or electronic solid-state switches. Operating pressure ranges from 0.15 to 1.0 MPa within a -20 to +70 C environment.

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 90 to 100 mm extend reach during press tooling changes, ensuring precise contact without swapping physical spacers.
Adapt end positions rapidly on large machining centers when switching between high-mass product families that require varying clamp depths.
Adjust the extend stop on automated pallet lifts to accommodate different pallet heights, tuning the upper travel limit on the fly.
When sizing this 140 mm bore actuator, stepping down to a 125 mm bore yields 6135.9 N push at 0.5 MPa, whereas stepping up to a 160 mm bore provides 10053.1 N push. If your end position never varies, a fixed-stroke ACQ cylinder is simpler and suffices. For this adjustable variant, confirm your ordering essentials: 140 mm bore, 100 mm full stroke, 10 mm adjuster window, the -S magnet, and the default female M22x2.5 rod-end thread.
Quick checklist
It provides 7696.9 N push and 7294.8 N pull at 0.5 MPa, 10775.7 N push at 0.7 MPa, and a maximum push of 1570 kgf at 1.0 MPa. The usable extend range is 90-100 mm, created by a 10 mm adjustment window subtracted from the 100 mm full stroke.
The external M27x2.0 threaded stop with lock nut limits only the extend length, meaning force is identical to a standard ACQ because the piston area is unchanged. The cylinder uses fixed elastomer bumpers instead of adjustable air cushions. Note that a plain compact cylinder does not hold its load on air loss; for fail-safe load holding, install an external rod lock or pilot-operated check valve.
