Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ140X200-10SB
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ140X200-10SB 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.

About the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ140X200-10SB
The AirTAC ACQJ140X200-10SB is a double-acting, single-rod JIS compact cylinder featuring an external threaded stop with a lock nut that limits the extend end position. You can fine-tune the usable extend range from 190 mm up to the full 200 mm stroke directly on the machine without changing parts. The retract stroke remains completely unaffected by this adjustment.
Because the piston area is unchanged, the force output is identical to a standard ACQ of this bore, delivering 7696.9 N push and 7294.8 N pull at 0.5 MPa. This big-bore compact variant features a 32 mm rod, PT3/8 port, and an M27x2.0 external adjuster thread. It includes fixed elastomer bumpers at both ends for end-of-stroke deceleration and a built-in piston magnet for switch sensing.

| Model | Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ140X200-10SB |
|---|---|
| Series | ACQJ JIS compact adjustable-stroke cylinder |
| Bore size | Ø140 mm |
| Full stroke | 200 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 ACQJ140X200-10SB Is Used
Heavy Press Tonnage Setup
Dial in the exact 190-200 mm extend position during initial press fixture setup, preventing over-travel without machining new spacers.
Automotive Welding Changeover
Accommodate different chassis frame sizes on a robotic welding line by quickly adjusting the extend stop rather than swapping entire actuators.
Large Clamp Positioning
Establish trial end positions for heavy-duty clamping mechanisms in heavy machinery assembly, ensuring perfect grip before locking the nut.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ140X200-10SB the Right Cylinder?
If you need slightly less force, the 100 mm bore provides 3927.0 N push at 0.5 MPa, while the 160 mm bore offers 10053.1 N push if your application requires more power. If your setup never requires end-position modifications, a fixed-stroke ACQ cylinder is sufficient. When ordering this adjustable version, confirm the 140 mm bore, 200 mm full stroke, 10 mm window, the -S magnet for sensing, and the -B male piston rod thread (M30x1.5) which couples directly to your load.
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 ACQJ140X200-10SB FAQ
The usable extend range is 190-200 mm (200 mm full stroke minus up to a 10 mm window). The retract stroke is unaffected. Force is identical to a standard ACQ: push is 7696.9 N and pull is 7294.8 N at 0.5 MPa, push is 10775.7 N at 0.7 MPa, and max push is 1570 kgf at 1.0 MPa.
The external M27x2.0 threaded stop with lock nut limits extension length only; it does not alter piston area, so force remains unchanged. The cylinder uses fixed elastomer bumpers, not adjustable air cushions. Note that a plain ACQ does not hold its load on air loss—use an external rod lock or pilot-operated check valve for fail-safe holding.
