Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ125X200-30S
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ125X200-30S is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø125mm 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 ACQJ125X200-30S
The AirTAC ACQJ125X200-30S is a double-acting, single-rod JIS compact cylinder featuring a big 125mm bore and a 200mm full stroke. An external threaded stop with a lock nut limits the EXTEND end position, allowing you to fine-tune the usable extend range from 170mm up to 200mm directly on the machine. The RETRACT stroke remains completely unaffected by this adjustment.
Because the piston area is unchanged, the output force is identical to a standard ACQ of this size. At 0.5 MPa, it delivers 6135.9N of push force and 5733.8N of pull force. It includes a -S piston magnet for position sensing and uses fixed elastomer bumpers at both ends for deceleration.

| Model | Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ125X200-30S |
|---|---|
| Series | ACQJ JIS compact adjustable-stroke cylinder |
| Bore size | Ø125 mm |
| Full stroke | 200 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 ACQJ125X200-30S Is Used
Heavy Press Tuning
Dial in the exact extend stop during heavy press setup to accommodate varying material thicknesses without machining new hard stops.
Automotive Fixture Changeover
Shift the extend position rapidly during product changeover on automotive assembly lines to accept new part geometries.
Palletizer End Stops
Test and set precise end positions for packaging arms handling different pallet sizes before locking the nut.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ125X200-30S the Right Cylinder?
For lower force needs, the 100mm bore provides 3927.0N push @0.5 MPa, while the 140mm bore offers 7696.9N push @0.5 MPa if higher output is required. A fixed-stroke ACQ is sufficient if your extend end position never varies. When ordering this adjustable model, confirm the 125mm bore, 200mm full stroke, 30mm window, -S magnet, and the default female M22x2.5 rod-end 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 ACQJ125X200-30S FAQ
The usable extend range is 170-200mm (200mm full stroke minus a 30mm window). Force is identical to a standard ACQ: 6135.9N push and 5733.8N pull @0.5 MPa, 8590.3N push @0.7 MPa, and a max push of 1251 kgf @1.0 MPa.
The external M27x2.0 threaded stop with lock nut limits only the extend length; force is unchanged. Fixed elastomer bumpers handle deceleration, but a plain ACQ does not hold loads on air loss—use an external rod lock or pilot-operated check valve for fail-safe holding.
