Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X30-20S
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X30-20S is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø160mm bore and 30mm 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 ACQJ160X30-20S
The AirTAC ACQJ160X30-20S is a big-bore JIS compact pneumatic cylinder featuring an external threaded stop with a lock nut to fine-tune the extend end position. With a 30 mm full stroke and a 20 mm adjustment window, the usable extend range spans 10 to 30 mm. The retract stroke remains completely unaffected by this mechanism.
Force output is identical to a standard ACQ of the same bore, delivering 10053.1 N push at 0.5 MPa, because the adjuster only alters travel length rather than piston area. This double-acting single-rod unit incorporates a 40 mm piston rod, an M24x3.0 female rod-end thread, and a PT3/8 port. It relies on fixed NBR elastomer bumpers at both ends for end-of-stroke deceleration, and the -S magnet enables position sensing using either reed or solid-state switches.

| 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 ACQJ160X30-20S Is Used
Heavy Press Tonnage
Provides exact downward ram positioning on large metalforming presses during die trial runs and prototype stamping.
Mold Clamp Positioning
Sets variable end stops for injection molding machines to accommodate differing mold depths and tooling heights.
Large Assembly Rams
Dialing in precise extend distances on heavy-duty automotive assembly rams without swapping out the whole cylinder.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X30-20S the Right Cylinder?
Selecting this 160 mm bore actuator provides massive thrust up to 2050 kgf at 1.0 MPa. If your application requires less force, stepping down to the 140 mm bore yields 7696.9 N push at 0.5 MPa, whereas no larger bore exists in this compact family. A standard fixed-stroke ACQ is sufficient if your end position never varies. To order, confirm the 30 mm full stroke, the 20 mm 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 ACQJ160X30-20S FAQ
The push force is 10053.1 N and pull is 9424.8 N at 0.5 MPa, with a push of 14074.3 N at 0.7 MPa and a maximum push of 2050 kgf at 1.0 MPa. The full stroke is 30 mm with a 20 mm window, allowing a usable extend range of 10-30 mm.
The external M36x2.0 threaded stop with lock nut limits the extend travel, but force remains identical to a standard ACQ because the piston area is unchanged. The cylinder uses fixed elastomer bumpers, and since it does not hold loads on air loss, an external rod lock or pilot-operated check valve is recommended for fail-safe holding.
