Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X175-40S
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X175-40S 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 ACQJ160X175-40S
The ACQJ160X175-40S is a double-acting JIS compact cylinder from the big-bore AirTAC range, engineered for heavy-duty applications within a space-efficient footprint. It features a 160mm bore, a 40mm piston rod, and a 175mm full stroke. An external threaded stop with a lock nut restricts the extend end position, yielding a usable forward travel range of 135 to 175mm. The return stroke remains completely unaffected.
Because the adjustment mechanism only limits forward travel without altering the piston area, the output force remains identical to a standard ACQ of this size. At 0.5 MPa, it delivers 10053.1N of push force and 9424.8N of pull force. The cylinder relies on a fixed NBR elastomer bumper for end-of-stroke deceleration rather than an adjustable air cushion, and the integrated -S magnet enables position detection using either reed or solid-state electronic switches.
Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X175-40S Technical Specifications
| Model | Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X175-40S |

| 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 ACQJ160X175-40S Is Used
Press Tooling Setup
Dial in the exact clamping depth on large metal stamping presses during tool trials, using the external stop to prevent over-travel without machining new spacers.
Automotive Welding Line
Accommodate varying vehicle subframe widths on a welding conveyor by repositioning the extend stop within the 135-175mm window during product changeovers.
Pallet Positioning
Fine-tune the final push-off distance for heavy pallets at the end of a packaging line, allowing operators to adjust the end position on the machine safely.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X175-40S the Right Cylinder?
When sizing this big-bore unit, consider the adjacent bore options for your force requirements. Dropping down to a 140mm bore yields 7696.9N push at 0.5 MPa, while stepping up to the maximum 160mm bore provides 10053.1N push at 0.5 MPa and a maximum push capacity of 2050 kgf at 1.0 MPa. If your application requires a fixed end position without variation, a standard ACQ cylinder will suffice. For the ACQJ160X175-40S, verify your ordering essentials: 160mm bore, 175mm full stroke, 40mm adjuster window, the -S magnet option, and the default female rod-end thread (M24x3.0).
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 ACQJ160X175-40S FAQ
This cylinder provides 10053.1N push and 9424.8N pull at 0.5 MPa, 14074.3N push at 0.7 MPa, and a maximum push of 2050 kgf at 1.0 MPa. The full stroke is 175mm, and with the 40mm adjustable window, the usable extend range is 135-175mm.
The external M36x2.0 threaded stop with a lock nut limits the extend length without changing the piston area, meaning force is identical to a standard ACQ. The cylinder uses a fixed NBR bumper, not an adjustable air cushion. Note that a plain ACQ-type cylinder does not hold its load on air loss; for fail-safe holding, an external rod lock or pilot-operated check valve is required.
