Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ140X150-30SB
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ140X150-30SB 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 ACQJ140X150-30SB
The AirTAC ACQJ140X150-30SB is a double-acting JIS compact cylinder from the big-bore range, featuring a 150mm full stroke and a 30mm external adjustment window. An external threaded stop with a lock nut restricts how far the rod extends, yielding a usable forward range of 120 to 150mm. The return stroke remains completely unaffected by this mechanism.
Because the piston area is unchanged, output force mirrors a standard ACQ of this size, giving 7696.9N push and 7294.8N pull at 0.5MPa. The unit includes a male M30x1.5 rod-end thread for direct mounting, a PT3/8 port, and fixed NBR elastomer bumpers at each end. The integrated piston magnet (-S) supports both reed and solid-state electronic switches for position sensing.

| Model | Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ140X150-30SB |
|---|---|
| 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 ACQJ140X150-30SB Is Used
Press Tooling Setup
Dial in exact clamping depth on large metal forming presses during initial tool tryout, using the M27x2.0 adjuster to find the perfect 120-150mm end position without machining new spacers.
Heavy Assembly Form Stops
Adapt large automotive component assembly lines for varying part widths by quickly repositioning the extend stop, ensuring heavy actuators hit precise targets during product changeovers.
Lifting Platform Limits
Control the exact raise height of heavy-duty pneumatic lifting platforms in material handling systems, tweaking the upper travel limit on the machine to accommodate different pallet stack heights.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ140X150-30SB the Right Cylinder?
Choosing this 140mm bore provides 7696.9N push at 0.5MPa. If your application requires less thrust, stepping down to a 125mm bore yields 6135.9N, while moving up to a 160mm bore offers 10053.1N. A fixed-stroke ACQ is sufficient if your end position never varies, but this adjustable variant is essential for setups requiring on-the-fly position tuning. Confirm ordering essentials: 140mm bore, 150mm full stroke, 30mm window, magnet (-S), and male rod thread (-B).
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 ACQJ140X150-30SB FAQ
The usable extend range is 120-150mm (150mm full stroke minus up to 30mm). Force is identical to a standard ACQ of this bore: 7696.9N push and 7294.8N pull at 0.5MPa, 10775.7N push at 0.7MPa, and a maximum push of 1570kgf at 1.0MPa.
An external M27x2.0 threaded stop with a lock nut limits only the extend length; the retract stroke and piston force remain unchanged. The cylinder uses fixed NBR elastomer bumpers at each end for deceleration. For fail-safe load holding on air loss, an external rod lock or pilot-operated check valve is required, as the bumper only cushions near stroke end.
