Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X200-30SB
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X200-30SB is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø160mm bore and 200mm 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 ACQJ160X200-30SB
The ACQJ160X200-30SB is a double-acting, big-bore JIS compact cylinder engineered for heavy-duty applications. It features a 160mm bore, a 40mm piston rod, and a 200mm full stroke. An external threaded stop with a lock nut permits precise adjustment of the extend end position directly on your equipment. The usable extend range spans 170mm to 200mm, while the retract stroke remains completely unaffected.
Because the adjustment mechanism limits travel length without altering the piston area, output force is identical to a standard ACQ of this size. You get 10053.1N of push force at 0.5 MPa and 9424.8N of pull force. The unit incorporates fixed NBR elastomer bumpers at both ends for deceleration and includes a male M36x1.5 rod-end thread for direct load coupling. A built-in piston magnet accommodates either reed or solid-state electronic switches.

| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.15 – 1.0 MPa |
| Proof pressure | 1.5 MPa |

| 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 ACQJ160X200-30SB Is Used
Heavy Press Tonnage
Dial in the exact 170-200mm extend reach during press setup, accommodating different die heights without machining new spacers.
Large Mold Changeover
Adapt the forward stop position rapidly on a large injection molding machine when switching between product tooling profiles.
Lift Station Calibration
Establish precise trial end positions for heavy lifting platforms, tweaking the extend limit safely before finalizing the mechanical hard stop.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X200-30SB the Right Cylinder?
Choosing this 160mm bore provides 10053.1N push force at 0.5 MPa. If you require less thrust, the 140mm bore variant yields 7696.9N push force. For even higher capacity, no larger standard bore exists in this series. A fixed-stroke ACQ is sufficient if your end position never varies. When ordering, verify the 200mm full stroke, the 30mm adjustment window, the -S magnet for sensor tracking, and the -B male rod thread. Note that a plain compact cylinder drifts on air loss; utilize an external rod lock for fail-safe load holding.
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 ACQJ160X200-30SB FAQ
At 0.5 MPa, push force is 10053.1N and pull force is 9424.8N; at 0.7 MPa, push is 14074.3N. Maximum push force is 2050kgf at 1.0MPa. The full stroke is 200mm with a 30mm adjustment window, yielding a usable extend range of 170-200mm. The piston rod is 40mm, the male rod-end thread is M36x1.5, the female thread is M24x3.0, the adjuster thread is M36x2.0, and the port is PT3/8.
The external threaded stop with a lock nut physically limits how far the rod extends, shortening the extend stroke without altering piston area, so force remains identical to a standard ACQ. The retract stroke is unaffected. Deceleration relies on fixed NBR elastomer bumpers at both ends, not adjustable air cushions; for high-energy cycles, add an external shock absorber. The -S magnet works with reed or solid-state electronic switches.
