Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X175-10S
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X175-10S is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø160mm bore and 175mm 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 ACQJ160X175-10S
The AirTAC ACQJ160X175-10S is a double-acting, single-rod JIS compact cylinder featuring an external extend stop. A threaded adjuster with a lock nut limits how far the rod travels forward, yielding a usable extension range of 165-175 mm from the 175 mm full stroke. The retract distance remains completely unaffected.
Because the piston area stays constant, output force matches a standard ACQ of this bore exactly, delivering 10053.1 N push at 0.5 MPa. This big-bore unit uses a 40 mm rod, PT3/8 ports, and fixed NBR elastomer bumpers at each end. The included -S magnet engages reed or solid-state switches via integrated body grooves.

| Series | ACQJ JIS compact adjustable-stroke cylinder |
| Bore size | Ø160 mm |
| Full stroke | 175 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 ACQJ160X175-10S Is Used
Heavy Press Tonnage Setup
Dial in the exact 165-175 mm extend position during heavy press commissioning without machining new stop spacers for varying material thicknesses.
Large Fixture Changeover
Adapt large automotive welding fixtures rapidly by turning the external M36x2.0 adjuster to meet new model dimensions instead of swapping cylinders.
Assembly Pression Tuning
Find the precise end-of-stroke clamping position on an assembly press for trial runs, locking the nut once the optimal 165-175 mm depth is achieved.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X175-10S the Right Cylinder?
When sizing this 160 mm bore unit, note the 10053.1 N push force at 0.5 MPa. Dropping to a 140 mm bore lowers thrust to 7696.9 N, while stepping up is unavailable as this is the largest big-bore option. If your machine never requires altering the end position, a fixed-stroke ACQ cylinder will suffice. To order, confirm the 175 mm full stroke, 10 mm window, -S magnet, and the default female M24x3.0 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 ACQJ160X175-10S FAQ
Force is identical to a standard ACQ: 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 usable extend range is 165-175 mm (175 mm full stroke minus a 10 mm window). The external adjuster thread is M36x2.0, the rod is 40 mm, and the port is PT3/8.
An external threaded screw with a lock nut physically limits the forward extension distance without altering the piston area, meaning thrust remains unchanged. The retract stroke is unaffected. The cylinder uses fixed NBR elastomer bumpers, not adjustable air cushions. It will not hold a load on air loss; for fail-safe holding, use an external rod lock or pilot-operated check valve.
