Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X300-10S
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X300-10S is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø160mm bore and 300mm 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 ACQJ160X300-10S
The AirTAC ACQJ160X300-10S is a double-acting, single-rod JIS compact cylinder engineered for heavy-duty applications. It features an external threaded stop with a lock nut that limits the extend end position, providing a usable extend range of 290 to 300 mm. The retract stroke remains completely unaffected. Because the piston area is unchanged, the output force is identical to a standard ACQ of this bore, delivering 10053.1 N of push force at 0.5 MPa.
This big-bore variant features a 40 mm piston rod, PT3/8 ports, and a female M24x3.0 rod-end thread. The external adjuster utilizes an M36x2.0 thread for precise positioning. The cylinder body incorporates fixed NBR elastomer bumpers at each end for end-of-stroke deceleration, and the integrated piston magnet (-S) is fully compatible with both reed and electronic solid-state switches.

| Bore size | Ø160 mm |
| Full stroke | 300 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 ACQJ160X300-10S Is Used
Heavy Press Tooling
Dial in the exact 290-300 mm extend position during press tooling setup or product changeover without machining new spacer blocks.
Large Assembly Stations
Adjust the end stop on large automotive assembly lines to accommodate varying chassis dimensions quickly and safely.
Material Handling Lifts
Fine-tune the extend stroke on heavy-duty lifting fixtures to set precise heights for different pallet sizes.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X300-10S the Right Cylinder?
When sizing this model, consider the neighboring bore options. Stepping down to a 140 mm bore yields 7696.9 N of push force at 0.5 MPa, whereas stepping up is not available as 160 mm is the maximum bore in this compact range. If your application requires a fixed end position and does not need on-machine stroke tuning, a standard ACQ cylinder will suffice. To order, confirm the 160 mm bore, 300 mm full stroke, 10 mm adjustable window, the -S magnet option, and the default female 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 ACQJ160X300-10S FAQ
The usable extend range is 290-300 mm (full 300 mm stroke minus up to 10 mm). The force is identical to a standard ACQ of this bore: push is 10053.1 N and pull is 9424.8 N at 0.5 MPa, push is 14074.3 N at 0.7 MPa, and maximum push is 2050 kgf at 1.0 MPa.
The external M36x2.0 threaded stop with lock nut limits the extend stroke length only; it does not change the piston area or force. The cylinder uses fixed NBR elastomer bumpers at each end, not adjustable air cushions. Note that a plain ACQ-type cylinder does not hold its load on air loss; for a fail-safe hold, an external rod lock or pilot-operated check valve is required.
