Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ140X10-10S
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ140X10-10S is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø140mm bore and 10mm 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 ACQJ140X10-10S
The AirTAC ACQJ140X10-10S is a double-acting JIS compact cylinder featuring a big-bore 140 mm design and an external threaded stop. This mechanism allows on-machine extend end-position tuning without swapping components. The full 10 mm stroke can be shortened by up to a 10 mm window, yielding a usable extend range of 0 to 10 mm, while the retract stroke remains unaffected.
Output force stays identical to a standard ACQ of this size because the piston area is unchanged by the adjuster. At 0.5 MPa it provides 7696.9 N push and 7294.8 N pull, reaching 10775.7 N push at 0.7 MPa. The unit includes a Ø32 mm piston rod, a PT3/8 port, fixed NBR elastomer bumpers, and an M27x2.0 adjuster thread.

| 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 ACQJ140X10-10S Is Used
Press Tooling Setup
Dialing in the exact extend position on heavy stamping presses during initial tool setup, allowing operators to tweak the 0-10 mm contact point without machining custom spacers.
Automotive Component Stands
Adjusting end stops on automotive welding fixtures when shifting between slightly different sub-component lengths, using the external lock nut to rapidly modify the extend reach.
Heavy Lifting Platforms
Fine-tuning the upper travel limit on large material handling lifts where a fixed 10 mm stroke needs slight reduction to prevent over-travel into delicate tooling.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ140X10-10S the Right Cylinder?
When sizing this big-bore variant, 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 equipment never requires modifying the extend endpoint, a fixed-stroke ACQ cylinder is sufficient. For ordering, confirm the 140 mm bore, 10 mm full stroke, 10 mm window, the -S magnet, and the default female M22x2.5 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 ACQJ140X10-10S FAQ
The usable extend range is 0 to 10 mm (a 10 mm full stroke minus up to a 10 mm window). It delivers 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 retract stroke is unaffected by the adjustment.
No, the adjuster only limits the extend stroke length, meaning force remains identical to a standard ACQ of the same bore. The cylinder uses fixed NBR elastomer bumpers for deceleration rather than an adjustable air cushion. Note that a plain compact cylinder does not hold its load on air loss; for fail-safe holding, install an external rod lock or pilot-operated check valve. The -S magnet works with reed or electronic solid-state switches.
