Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ140X150-100SB
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ140X150-100SB is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø140mm 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 ACQJ140X150-100SB
The AirTAC ACQJ140X150-100SB is a double-acting JIS compact cylinder featuring an external threaded stop with a lock nut that limits the extend end position. You can fine-tune the usable extend stroke anywhere from 50 mm up to the full 150 mm on the machine without swapping parts, while the retract stroke remains completely unaffected. It incorporates a male M30x1.5 piston rod end for direct load coupling and a PT3/8 port.
Because the adjuster only alters travel length and not piston area, the generated force remains identical to a standard ACQ of this bore. This big-bore compact variant delivers 7696.9 N of push force at 0.5 MPa and features fixed NBR elastomer bumpers at both ends for end-of-stroke deceleration. The integrated piston magnet (-S) supports both reed and solid-state electronic switches for precise position sensing.
Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ140X150-100SB Technical Specifications
| Model | Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ140X150-100SB |
|---|---|
| Series | ACQJ JIS compact adjustable-stroke cylinder |
| Bore size | Ø140 mm |
| Full stroke | 150 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 (Ø140mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 7697 N | 7295 N |
| 0.7 MPa | 10776 N | — |
| Max (@1.0 MPa) | 1570 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 ACQJ140X150-100SB Is Used
Press Tonnage Setup
Vary the extend stop during press tooling setup to test different material deformation depths without machining new spacer rings.
Heavy Fixture Changeover
Modify the extend end position rapidly on an automated assembly line when switching between heavy product variants.
Palletizer End Stops
Adjust the extend stroke on a packaging palletizer to handle different pallet heights or oversized box dimensions smoothly.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ140X150-100SB the Right Cylinder?
If you require less thrust, stepping down to the 125 mm bore yields 6135.9 N of push force at 0.5 MPa, whereas stepping up to the 160 mm bore provides 10053.1 N. If your application never requires end-position adjustments, a fixed-stroke ACQ cylinder will suffice. When ordering this model, confirm the 140 mm bore, 150 mm full stroke, 100 mm adjustable 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 ACQJ140X150-100SB FAQ
It provides a push force of 7696.9 N and a pull force of 7294.8 N at 0.5 MPa, and 10775.7 N of push at 0.7 MPa. The maximum push force is 1570 kgf at 1.0 MPa. The full stroke is 150 mm with a 100 mm window, giving a usable extend range of 50-150 mm.
The external M27x2.0 threaded stop with a lock nut limits the extend travel, allowing on-machine tuning without changing parts. It changes stroke length only, so force remains identical to a standard ACQ. Fixed elastomer bumpers decelerate the load near stroke ends, though a plain cylinder will drift on air loss, requiring an external rod lock for fail-safe holding.
