Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X250-10S
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X250-10S 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 ACQJ160X250-10S
The AirTAC ACQJ160X250-10S is a double-acting, single-rod JIS compact cylinder from the big-bore range, accommodating standard strokes up to 300 mm. An external threaded stop with a lock nut limits the extend end position, yielding a usable forward range of 240-250 mm (a 10 mm adjustment window off the 250 mm full stroke). The retract movement remains completely unaffected by this mechanism.
Because the piston area stays constant, output force equals that of a standard ACQ of this size: 10053.1 N push and 9424.8 N pull at 0.5 MPa. The unit integrates fixed elastomer bumpers for end-of-stroke deceleration and, with the built-in -S magnet, supports both reed and electronic solid-state switches via its dedicated grooves.

| Bore size | Ø160 mm |
| Full stroke | 250 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 ACQJ160X250-10S Is Used
Heavy Press Tonnage Calibration
Dial in the exact 240-250 mm extend position on large metal-forming presses during setup, ensuring precise upper-die contact before full clamping without machining new stop spacers.
Automotive Welding Fixture Changeover
Adapt large robotic weld gun clamps for differing body panel heights by turning the external M36x2.0 adjuster, hitting varied end stops rapidly on the assembly floor.
Large Mold Handling and Ejection
Fine-tune the ejection stroke on heavy injection molding machinery, preventing premature mold contact while retaining the full 9424.8 N pull force at 0.5 MPa for part extraction.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X250-10S the Right Cylinder?
When sizing this 160 mm bore actuator, stepping down to a 140 mm bore yields 7696.9 N push at 0.5 MPa, whereas stepping up is unavailable within this series. If your process requires a permanent 250 mm extension without end-position tuning, a fixed-stroke ACQ cylinder provides the same holding force more economically. To order this adjustable variant correctly, verify the 160 mm bore, the 250 mm full stroke, the 10 mm window, the -S magnet for sensing, and the default female M24x3.0 rod-end 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 ACQJ160X250-10S FAQ
This big-bore 160 mm cylinder provides 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 250 mm, with a 10 mm adjustment window yielding a usable extend range of 240-250 mm.
The external M36x2.0 threaded stop with lock nut limits only the extend length, leaving the retract stroke unchanged. It modifies stroke distance only, so force remains identical to a standard ACQ. Note that this plain cylinder does not hold its load on air loss; for fail-safe holding, use an external rod lock or pilot-operated check valve, as the fixed elastomer bumper only decelerates near stroke end.
