Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ140X175-10S
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ140X175-10S is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø140mm bore and 175mm 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 ACQJ140X175-10S
The AirTAC ACQJ140X175-10S is a double-acting JIS compact cylinder with an external threaded stop and lock nut that limits the extend end position. You get a usable extend range of 165-175 mm from the 175 mm full stroke, while the retract stroke remains completely unaffected. An M27x2.0 adjuster thread allows precise on-machine end-position tuning without changing parts.
Because the piston area is unchanged, force output is identical to a standard ACQ of this bore: 7696.9 N push and 7294.8 N pull at 0.5 MPa. This big-bore compact variant features a 32 mm piston rod, PT3/8 porting, and a fixed NBR elastomer bumper at each end. The included -S magnet works with reed or electronic solid-state switches for position sensing.
Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ140X175-10S Technical Specifications
| Model | Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ140X175-10S |
|---|---|
| Series | ACQJ JIS compact adjustable-stroke cylinder |
| Bore size | Ø140 mm |
| Full stroke | 175 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 ACQJ140X175-10S Is Used
Press Tonnage Calibration
Dial in the exact 165-175 mm extend stop during press setup to calibrate tonnage on varying material thicknesses without machining new spacers.
Heavy Fixture Changeover
Shift the extend limit by up to 10 mm instantly when swapping large machining fixtures on a production line, minimizing line downtime.
Large Assembly Positioning
Establish trial end positions for heavy automotive assembly actuators, allowing operators to tweak the stroke limit safely during prototype runs.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ140X175-10S the Right Cylinder?
Selecting this 140 mm bore provides 7696.9 N push at 0.5 MPa, sitting between the 100 mm bore (3927.0 N) and the 160 mm bore (10053.1 N). If your extend position never varies, a fixed-stroke ACQ cylinder is simpler and suffices. When ordering, confirm the 140 mm bore, 175 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 ACQJ140X175-10S FAQ
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 175 mm full stroke has a 10 mm adjustable window, giving a usable extend range of 165-175 mm. Operating pressure is 0.15-1.0 MPa.
The external M27x2.0 threaded stop with a lock nut limits the extend stroke length only, meaning force is identical to a standard ACQ. The fixed NBR elastomer bumper decelerates the load near the end of stroke. Note that a plain cylinder does not hold its load on air loss; for fail-safe holding, use an external rod lock or pilot-operated check valve.
