Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X150-75S
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X150-75S is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø160mm bore and 150mm 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 ACQJ160X150-75S
The AirTAC ACQJ160X150-75S is a double-acting, JIS compact cylinder engineered with an external extend stop, enabling on-machine stroke tuning without replacing hardware. This big-bore variant features a 150 mm full stroke and a 75 mm adjustment window, yielding a usable extend range of 75 to 150 mm. The retract distance remains completely unaffected by the external adjuster.
Because the internal piston area is unchanged, output force stays identical to a standard ACQ of this size, delivering 10053.1 N of push force at 0.5 MPa. The Ø40 mm rod uses an M24x3.0 female thread, and the M36x2.0 external adjuster locks firmly with a nut. Fixed NBR elastomer bumpers absorb impact at both ends, while the integrated -S magnet interfaces seamlessly with reed or solid-state electronic switches.

| Bore size | Ø160 mm |
| Full stroke | 150 mm |
| 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 |
| Temperature | -20 to +70 °C |
| 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 ACQJ160X150-75S Is Used
Heavy Press Tonnage Calibration
Dial in the exact 75 to 150 mm extend position on a large metal stamping press during setup, allowing rapid recalibration for different die heights without machining new spacers.
Automotive Assembly Line Stops
Modify end-of-stroke endpoints on the fly for product changeovers, accommodating varying chassis widths on a single conveyor line using the external M36x2.0 adjuster.
Palletizer End-Effector Tuning
Fine-tune the gripping arm extension reach for mixed pallet sizes, testing trial end positions quickly before locking the nut down for high-speed packaging cycles.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X150-75S the Right Cylinder?
Selecting this 160 mm bore provides a massive 2050 kgf maximum push at 1.0 MPa, stepping up from the 140 mm bore (7696.9 N push @0.5 MPa). If your equipment requires the absolute maximum extend length, the fixed-stroke ACQ variant is sufficient. When specifying, verify the 150 mm full stroke, the 75 mm window, the -S magnet, and the female M24x3.0 rod thread. Note that a plain compact cylinder drifts on air loss; for fail-safe load holding, add an external rod lock or pilot-operated check valve.

- ✓ 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 ACQJ160X150-75S FAQ
It delivers 10053.1 N push and 9424.8 N pull at 0.5 MPa, 14074.3 N push at 0.7 MPa, and a maximum push of 2050 kgf at 1.0 MPa. The full stroke is 150 mm with a 75 mm window, allowing an adjustable extend range of 75 to 150 mm.
No, the external threaded stop only limits how far the rod extends, leaving the piston area untouched so force remains identical to a standard ACQ. The retract stroke is unaffected, and fixed NBR bumpers decelerate the load at both ends rather than using adjustable air cushions.
