Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X175-20SB
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X175-20SB 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 ACQJ160X175-20SB
The AirTAC ACQJ160X175-20SB is a double-acting, single-rod JIS compact cylinder engineered for heavy-duty applications. It features a 160mm bore and a 175mm full stroke, generating 10053.1N of push force at 0.5MPa and a maximum push of 2050kgf at 1.0MPa. An external M36x2.0 threaded stop with a lock nut restricts the extend end position, yielding a usable extend range of 155-175mm without altering parts. The retract stroke remains completely unaffected.
Because the piston area is unchanged, the output force is identical to a standard ACQ of this bore. This big-bore compact variant supports up to 300mm strokes and includes fixed NBR elastomer bumpers at both ends for end-of-stroke deceleration. Equipped with the -S option, it carries a built-in piston magnet compatible with reed or electronic solid-state switches, while the -B option provides an M36x1.5 male rod-end thread for direct load coupling. The standard port size is PT3/8.
Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X175-20SB Technical Specifications
| Model | Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X175-20SB |
|---|---|
| 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 ACQJ160X175-20SB Is Used
Heavy Press Tonnage Setup
Dial in the exact extend endpoint on a multi-ton metal forming press during initial tooling setup, using the external stop to find the perfect striking distance without machining custom spacers.
Automotive Assembly Changeover
Rapidly adapt a large automotive body-welding fixture for different chassis dimensions by adjusting the extend stroke window from 175mm down to 155mm during model line changeovers.
Large Mold Clamping Trials
Test varying clamping depths on heavy injection molding platens, fine-tuning the extend position on the fly to verify mold fit and pressure distribution before finalizing the mechanical stops.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X175-20SB the Right Cylinder?
When sizing this 160mm bore actuator, dropping to a 140mm bore reduces the 0.5MPa push force to 7696.9N, while stepping up is not available in this compact series. If your machine setup never requires varying the extend endpoint, a fixed-stroke ACQ cylinder will suffice. To order this adjustable model correctly, confirm the 160mm bore, 175mm full stroke, 20mm adjuster window, the -S magnet for sensing, and the -B male rod thread. Keep in mind a plain compact cylinder will drift on air loss; for fail-safe load holding, specify an external rod lock or pilot-operated check valve.
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 ACQJ160X175-20SB FAQ
This 160mm bore cylinder provides 10053.1N push and 9424.8N pull force at 0.5MPa, 14074.3N push at 0.7MPa, and a maximum push of 2050kgf at 1.0MPa. The full stroke is 175mm, and the external adjuster allows the extend stroke to be shortened by up to 20mm, yielding a usable extend range of 155-175mm.
No, the external M36x2.0 threaded stop only changes the extend end position, not the piston area, so force remains identical to a standard ACQ. The retract stroke is unaffected, and fixed NBR elastomer bumpers decelerate the load at both ends. For high-energy approaches, an external shock absorber may be required.
