Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X150-30S
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X150-30S is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø160mm bore and 150mm 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 ACQJ160X150-30S
The AirTAC ACQJ160X150-30S is a double-acting JIS big-bore compact cylinder featuring an external threaded stop with a lock nut to limit the extend end position. You can fine-tune the usable extend stroke from 120 mm up to the full 150 mm directly on the machine without swapping parts, while the retract stroke remains completely unaffected.
Because the piston area stays the same, output force is identical to a standard ACQ of this bore, delivering 10053.1 N push at 0.5 MPa. The Ø40 mm rod uses an M24x3.0 female thread, and the body integrates fixed NBR elastomer bumpers at each end alongside magnetic-switch grooves for reed or solid-state sensors.

| 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 ACQJ160X150-30S Is Used
Press Tonnage Setup
Dial in the exact 120-150 mm extend position during press tooling setup to accommodate varying material thicknesses without machining custom spacers.
Heavy Fixture Changeover
Adapt large automated welding clamps rapidly for different product frames by turning the external M36x2.0 adjuster rather than replacing the entire cylinder.
Bending Machine Trials
Establish precise trial end stops for heavy-gauge metal forming, relying on the fixed elastomer bumper to decelerate the 14074.3 N extend force at 0.7 MPa.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X150-30S the Right Cylinder?
Selecting this 160 mm bore yields a maximum push of 2050 kgf at 1.0 MPa. If your application requires less force, dropping to the 140 mm bore provides 7696.9 N push at 0.5 MPa, whereas no larger standard ACQJ bore exists in this compact range. If you never need to alter the extend end position, a fixed-stroke ACQ cylinder will suffice. When ordering, confirm the 150 mm full stroke, the 30 mm adjuster window, the built-in S magnet, 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 ACQJ160X150-30S FAQ
It delivers 10053.1 N push and 9424.8 N pull at 0.5 MPa, 14074.3 N push at 0.7 MPa, and a maximum push of 2050 kgf at 1.0 MPa. The full stroke is 150 mm with a 30 mm adjustable window, allowing an extend range of 120-150 mm. The retract stroke is unaffected, and the port size is PT3/8.
No, the adjuster only changes the extend stroke length, not the piston area, so force remains identical to a standard ACQ. The rod end features an M36x2.0 adjuster thread with a lock nut. Note that a plain ACQ-type does not hold its load on air loss; for fail-safe holding, use an external rod lock or pilot-operated check valve.
