Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ140X75-10SB
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ140X75-10SB is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø140mm bore and 75mm 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 ACQJ140X75-10SB
The AirTAC ACQJ140X75-10SB is a big-bore JIS compact, double-acting single-rod cylinder built for heavy-duty applications. It features an external M27x2.0 threaded stop with a lock nut on the rod-end side, allowing you to fine-tune the extend end position directly on the machine. With a 75 mm full stroke and a 10 mm adjustment window, the usable extend range spans 65 to 75 mm. The retract stroke remains completely unaffected by this mechanism.
Because the internal piston area is unchanged, the output force is identical to a standard ACQ of this bore, delivering 7696.9 N push and 7294.8 N pull at 0.5 MPa. This variant includes a male M30x1.5 piston rod end for direct load coupling, an integrated magnet (-S) for reed or solid-state sensors, and fixed NBR elastomer bumpers at each end. The PT3/8 port and 32 mm rod diameter handle operating pressures up to 1.0 MPa across a -20 to +70 °C range.

| 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 ACQJ140X75-10SB Is Used
Press Tonnage Calibration
Dial in the exact 65-75 mm extend position on a metal stamping press to set tonnage limits during tooling setup, using the external stop to adapt for varying material thicknesses.
Automotive Welding Line Changeover
Accommodate different chassis frame profiles on a robotic welding line by turning the M27x2.0 adjuster to shift the extend stop, ensuring precise clamp closure for each new vehicle variant.
Palletizer End-of-Arm Tooling
Fine-tune the gripping extension on a heavy-load palletizer when switching between oversized or irregularly sized product cartons, relying on the 7696.9 N push force to secure heavy payloads.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ140X75-10SB the Right Cylinder?
Select this Ø140 big-bore compact actuator when your fixture setup requires precise extend-end tuning within a 65-75 mm window without swapping cylinders. If exact 75 mm extension is always guaranteed, a fixed-stroke ACQ140X75SB is sufficient. For higher kinetic energy at cycle ends, add an external shock absorber since the built-in elastomer bumper is non-adjustable. Downgrading to a Ø125 bore drops push force to 6135.9 N at 0.5 MPa, while upgrading to a Ø160 bore increases it to 10053.1 N. Confirm your ordering essentials: 140 mm bore, 75 mm full stroke, 10 mm window, -S magnet, and -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 ACQJ140X75-10SB FAQ
This cylinder 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 75 mm with a 10 mm adjustment window, yielding a usable extend range of 65-75 mm. The external adjuster uses an M27x2.0 thread.
The external threaded stop limits how far the rod extends without altering the piston area, meaning force remains identical to a standard ACQ. The fixed NBR elastomer bumper decelerates the load near stroke ends but is not a brake. A plain ACQ-type cylinder will not hold its load on air loss; for fail-safe load holding, install an external rod lock or pilot-operated check valve.
