Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ140X175-100SB
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ140X175-100SB 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 ACQJ140X175-100SB
The AirTAC ACQJ140X175-100SB is a double-acting, big-bore JIS compact cylinder engineered for heavy-duty applications. An external M27x2.0 threaded stop and lock nut restricts the forward extend position, providing a usable extension range of 75 to 175 mm. The return retract stroke remains completely unaffected. A -B male M30x1.5 piston rod end couples directly to your load.
Because the adjuster only limits travel and leaves piston area unchanged, output force matches a standard ACQ of identical bore. At 0.5 MPa, it delivers 7696.9 N of push and 7294.8 N of pull, scaling to 10775.7 N push at 0.7 MPa, with a maximum push of 1570 kgf at 1.0 MPa. Fixed NBR elastomer bumpers decelerate impacts at each end, while the -S piston magnet interfaces seamlessly with reed or solid-state electronic switches.

| 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 ACQJ140X175-100SB Is Used
Press Tooling Tryout
Dial in exact clamping extension during stamping press setup and tooling verification without swapping out cylinders.
Heavy Fixture Changeover
Quickly modify extend endpoints to accommodate different large product dimensions on automated assembly lines.
Lifting Station Calibration
Fine-tune the lift height of heavy pallets in packaging stations to match varying load sizes on the fly.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ140X175-100SB the Right Cylinder?
Selecting this 140 mm bore unit is ideal when your setup requires substantial thrust alongside adaptable end positions. If your operation needs less power, scaling down to the 125 mm bore yields 6135.9 N push at 0.5 MPa. For even higher force, the 160 mm variant provides 10053.1 N push. If the forward endpoint never varies, a fixed-stroke ACQ cylinder is sufficient. To order, confirm the 140 mm bore, 175 mm full stroke, 100 mm adjuster window, the -S magnet for sensing, and the -B male 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 ACQJ140X175-100SB FAQ
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 full stroke is 175 mm with a 100 mm adjustment window, yielding a usable extend range of 75-175 mm. The retract stroke is unaffected.
An external M27x2.0 threaded screw with a lock nut limits the extend travel, meaning force remains identical to a standard ACQ because piston area is unchanged. Fixed NBR bumpers decelerate the stroke at both ends. 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.
