Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X250-30S
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X250-30S is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø160mm bore and 250mm 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 ACQJ160X250-30S
The AirTAC ACQJ160X250-30S is a double-acting, single-rod JIS compact cylinder featuring an external adjustable extend stop. An M36x2.0 threaded screw and lock nut limit the outward travel, providing a usable extend range of 220 to 250 mm. The return stroke remains completely unaffected. As a big-bore compact unit, it handles up to 300 mm of standard travel.
Because the piston area remains constant, output force is 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. The Ø40 mm rod utilizes an M24x3.0 female thread, and a PT3/8 port supplies air. Fixed NBR elastomer bumpers absorb end-of-stroke impact, while the included -S magnet enables position sensing with reed or solid-state switches.

| 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 ACQJ160X250-30S Is Used
Press Fixture Calibration
Dial in the exact clamping reach on heavy stamping presses during setup changes, utilizing the external stop to shorten the 250 mm stroke by up to 30 mm without swapping hardware.
Automotive Welding Stops
Adjust the extend position of large robotic welding actuators on the fly to accommodate varying chassis dimensions, relying on the fixed bumper to absorb the massive kinetic energy.
Heavy Lift Trial Positions
Test different lifting heights for heavy material handling rigs by fine-tuning the outward stop, ensuring precise placement before locking the nut and finalizing the cycle.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X250-30S the Right Cylinder?
Selecting this 160 mm bore unit means requiring massive thrust in a compact footprint. If 9424.8 N pull at 0.5 MPa is excessive, stepping down to a 140 mm bore yields 7294.8 N pull, whereas moving up is impossible as this represents the largest big-bore compact size available. A fixed-stroke ACQ is sufficient if your extend position never requires tweaking. When ordering, verify the 250 mm full stroke, the 30 mm window, the -S magnet for sensors, and the M24x3.0 female rod thread.
Quick checklist

- ✓ 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 ACQJ160X250-30S 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 full stroke is 250 mm, and the adjustable window is 30 mm, giving a usable extend range of 220 to 250 mm.
The external M36x2.0 threaded stop with lock nut limits only the extend stroke, leaving the return stroke unaffected. Force remains identical to a standard ACQ because piston area is unchanged. The fixed NBR bumpers decelerate the load near stroke end, but a plain cylinder does not hold its load on air loss; for fail-safe holding, install an external rod lock or pilot-operated check valve.
