Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ125X30-30S
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ125X30-30S is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø125mm 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 ACQJ125X30-30S
The ACQJ125X30-30S is a big-bore JIS compact double-acting cylinder engineered for on-machine extend position tuning. An external M27x2.0 threaded stop and lock nut lets you dial the extend stroke down from 30 mm to 0 mm without swapping parts. Retract travel remains fixed at the full 30 mm.
Because the adjuster only limits travel, the piston area stays intact, yielding force identical to a standard ACQ of this bore: 6135.9 N push and 5733.8 N pull at 0.5 MPa. This 125 mm variant features a 32 mm rod, PT3/8 porting, and NBR elastomer bumpers at both ends to absorb end-of-stroke energy.

| Model | Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ125X30-30S |
|---|---|
| Series | ACQJ JIS compact adjustable-stroke cylinder |
| Bore size | Ø125 mm |
| Full stroke | 30 mm |
| Adjuster thread | M27×2.0 |
| 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 | M22×2.5 (F) / M30×1.5 (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 (Ø125mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 6136 N | 5734 N |
| 0.7 MPa | 8590 N | — |
| Max (@1.0 MPa) | 1251 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 ACQJ125X30-30S Is Used
Press Tooling Setup
Dial in the exact extend stop during press tooling setup to accommodate varying material thicknesses without machining new spacer blocks.
Automated Product Changeover
Quickly reposition the extend end point on a packaging line during automated product changeover to handle different carton depths.
Welding Fixture Trial
Establish precise trial end positions on a heavy-duty welding fixture, fine-tuning the 0 to 30 mm range to locate clamps accurately.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ125X30-30S the Right Cylinder?
Selecting this model provides 6135.9 N push at 0.5 MPa; stepping down to a 100 mm bore drops push to 3927.0 N, while a 140 mm bore raises it to 7696.9 N. If your application never requires end-position tweaking, a fixed-stroke ACQ125X30 is sufficient. When ordering, confirm the 30 mm full stroke, 30 mm adjustment window, female M22x2.5 rod end, and the -S magnet for sensing.
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 ACQJ125X30-30S FAQ
This cylinder delivers 6135.9 N push and 5733.8 N pull at 0.5 MPa, 8590.3 N push at 0.7 MPa, and a maximum push of 1251 kgf at 1.0 MPa. The usable extend range is 0-30 mm (a 30 mm full stroke minus the 30 mm adjustment window).
The external M27x2.0 threaded stop limits extend travel only, meaning force remains identical to a standard ACQ. Fixed NBR bumpers absorb end-of-stroke impact. Note that this cylinder does not hold its load on air loss; for fail-safe holding, install an external rod lock or pilot-operated check valve.
