Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X250-30SB
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X250-30SB is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø160mm bore and 250mm 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 ACQJ160X250-30SB
The AirTAC ACQJ160X250-30SB is a double-acting, big-bore JIS compact cylinder featuring an external extend-stop mechanism. A threaded rod-end adjuster with an M36x2.0 thread and lock nut lets you dial in the extend position on the machine, providing a usable forward travel range of 220 to 250 mm. The return stroke remains completely unaffected. Because the piston area stays constant, output force mirrors a standard ACQ exactly, yielding 10053.1 N of push at 0.5 MPa.
This heavy-duty unit includes a male M36x1.5 piston rod end for direct load coupling and a built-in magnet (-S) for position sensing. It operates at 30-500 mm/s within a 0.15-1.0 MPa pressure range. Deceleration relies on fixed NBR elastomer bumpers at both ends rather than adjustable air cushions, so external shock absorbers are advised for high-energy approaches. Note that this cylinder will drift if air pressure is lost, requiring an external rod lock for fail-safe load holding.

| 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 |

| 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 ACQJ160X250-30SB Is Used
Heavy Press Tonnage Setup
Dial in the exact 220-250 mm extend stop on a multi-ton press without machining new spacers, accommodating varying material thicknesses on the fly.
Large Mold Changeover
Adjust the forward end position rapidly during mold swaps in automotive stamping lines, ensuring precise alignment without disassembling the actuator.
Custom Forming Depth
Fine-tune the trial end position for deep-draw metal forming equipment, tweaking the 30 mm window to perfect the draw depth before locking the nut.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X250-30SB the Right Cylinder?
Selecting this 160 mm bore provides massive thrust, pushing 10053.1 N and pulling 9424.8 N at 0.5 MPa. If your application needs slightly less force, stepping down to a 140 mm bore drops the push to 7696.9 N. Since 160 mm is the largest standard diameter in this compact range, higher force requirements demand multiple cylinders or a different frame design. If your end-position never varies, a fixed-stroke ACQ cylinder is simpler and suffices. When ordering, confirm the 250 mm total stroke, the 30 mm adjuster window, the -S magnet, and the -B male 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 ACQJ160X250-30SB FAQ
It delivers a push of 10053.1 N and pull of 9424.8 N at 0.5 MPa, 14074.3 N push at 0.7 MPa, and a maximum push of 2050 kgf at 1.0 MPa. The 250 mm total stroke features a 30 mm adjustable window, allowing a usable extend range of 220 to 250 mm.
The external M36x2.0 threaded stop with lock nut limits only the forward travel, leaving the retract stroke untouched. Force remains identical to a standard ACQ because the piston area is unchanged. The cylinder uses fixed elastomer bumpers, not air cushions, and will drift on air loss, so an external rod lock is needed for fail-safe holding.
