Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X40-10SB
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X40-10SB is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø160mm bore and 40mm 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 ACQJ160X40-10SB
The ACQJ160X40-10SB is a double-acting JIS compact cylinder with an external threaded stop and lock nut that restricts how far the rod extends. You can fine-tune the extend end position on the machine across a 30 to 40 mm usable range (a 10 mm window subtracted from the 40 mm full stroke). The retract stroke remains completely unaffected. As a big-bore variant, this unit supports standard strokes up to 300 mm.
Because the piston area is unchanged, the output force remains identical to a standard ACQ of this bore. At 0.5 MPa it delivers 10053.1 N of push force and 9424.8 N of pull force. It features a 40 mm piston rod with a male M36x1.5 thread for direct load coupling, PT3/8 ports, and fixed NBR elastomer bumpers at both ends rather than adjustable air cushions. The -S option includes a built-in piston magnet compatible with reed or electronic solid-state switches.

| Adjuster thread | M36×2.0 |
| Port size | PT3/8 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.15 – 1.0 MPa |
| Proof pressure | 1.5 MPa |

| Speed range | 30 – 500 mm/s |
| Rod thread | M24×3.0 (F) / M36×1.5 (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 (Ø160mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 10053 N | 9425 N |
| 0.7 MPa | 14074 N | — |
| Max (@1.0 MPa) | 2050 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 ACQJ160X40-10SB Is Used
Press Tooling Changeover
Dial in the exact extend position from 30 to 40 mm when swapping press dies, ensuring proper clearance without machining new spacer blocks.
Heavy Fixture Positioning
Secure heavy fabrication fixtures on large welding tables by externally tuning the end stop to match varying part heights on the fly.
Pallet Stop Calibration
Adjust the extend stroke to act as a physical hard stop for different pallet widths, accommodating product format changes without PLC adjustments.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X40-10SB the Right Cylinder?
When sizing this big-bore compact cylinder, compare it against the adjacent 140 mm bore, which yields 7696.9 N of push force at 0.5 MPa, or step up if your application exceeds the 2050 kgf maximum push at 1.0 MPa. A fixed-stroke ACQ is sufficient if your end position never varies, but this adjustable model is necessary for product-changeover setups. To order, confirm the 160 mm bore, 40 mm full stroke, 10 mm adjust window, the -S magnet for sensors, 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 ACQJ160X40-10SB FAQ
It provides 10053.1 N push and 9424.8 N pull force at 0.5 MPa, 14074.3 N push at 0.7 MPa, and a maximum push of 2050 kgf at 1.0 MPa. The usable extend range is 30 to 40 mm (a 10 mm window off the 40 mm full stroke). The retract stroke is unaffected, and the adjuster thread is M36x2.0.
No, the external stop alters only the extend stroke length, not the piston area, so force remains identical to a standard ACQ. Deceleration is handled by fixed NBR elastomer bumpers at each end rather than adjustable air cushions. For high-energy loads, use an external shock absorber or slow the approach speed.
