Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X175-100S
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X175-100S 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 ACQJ160X175-100S
The ACQJ160X175-100S is a double-acting JIS compact cylinder featuring a 160mm bore and an external threaded stop with a lock nut. This mechanism limits the extend end position, providing a usable outward range of 75 to 175mm. The retract stroke remains completely unaffected. Because the piston area is unchanged, output force is identical to a standard ACQ of this size.
Generating a push of 10053.1N and pull of 9424.8N at 0.5MPa, this big-bore unit operates at 0.15-1.0 MPa. It includes a Ø40mm piston rod, a PT3/8 port, and a fixed NBR elastomer bumper at each end. The integrated magnet (-S) supports both reed and solid-state switches for position sensing. Note that a plain air cylinder drifts upon air loss; utilize an external rod lock for fail-safe load holding.

| 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 ACQJ160X175-100S Is Used
Heavy Press Tonnage Setup
Dial in the exact extend end position during heavy press commissioning to accommodate varying material thicknesses without machining new spacer blocks.
Automotive Product Changeover
Rapidly reconfigure the extend stroke limit on an automotive assembly line when switching between different chassis variants or model types.
Large Mold Trial Positions
Test multiple end positions on large injection molding machinery to find the optimal ejection distance before finalizing mechanical stops.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X175-100S the Right Cylinder?
If your application requires slightly less thrust, the ACQJ140 model provides 7696.9N of push at 0.5MPa. Since this is the largest standard bore in this compact family, moving up would require a different series. If your end position never varies, a fixed-stroke ACQ cylinder is sufficient and simpler. When ordering, confirm the 160mm bore, 175mm full stroke, 100mm adjuster window, the -S magnet, 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 ACQJ160X175-100S FAQ
At 0.5MPa it delivers 10053.1N push and 9424.8N pull, with 14074.3N push at 0.7MPa and a maximum push of 2050kgf at 1.0MPa. The full stroke is 175mm with a 100mm adjustment window, giving a usable extend range of 75-175mm. The piston rod is Ø40mm, the port is PT3/8, the female rod-end thread is M24x3.0, and the external adjuster thread is M36x2.0.
The external adjuster changes the extend stroke length only; it does not alter piston area, so force remains identical to a standard ACQ. Deceleration relies on a fixed NBR elastomer bumper at each end, not an adjustable air cushion. For high kinetic energy loads, add an external shock absorber or slow the approach speed. The -S magnet works with reed or electronic solid-state switches.
