Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ125X150-100S
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ125X150-100S is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø125mm 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 ACQJ125X150-100S
The AirTAC ACQJ125X150-100S is a double-acting, single-rod JIS compact cylinder engineered for big-bore tasks, supporting up to 300mm standard strokes. An external M27x2.0 threaded stop and lock nut restricts the extend end position, yielding a usable forward travel range of 50-150mm from the 150mm full stroke. The return stroke remains completely unaffected by this mechanism.
Because the piston area stays constant, output force equals a standard ACQ of this bore: 6135.9N push and 5733.8N pull at 0.5MPa. The -S suffix equips the unit with a piston magnet compatible with reed or solid-state electronic switches. NBR elastomer bumpers fixed at each end absorb end-of-travel impact, as no adjustable air cushion is present.

| Series | ACQJ JIS compact adjustable-stroke cylinder |
| Bore size | Ø125 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 (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 ACQJ125X150-100S Is Used
Press Tooling Changeover
Dial in the exact extend stop from 50 to 150mm during product family swaps on heavy stamping lines, avoiding the need to machine custom physical spacers.
Heavy Fixture Positioning
Fine-tune clamping reach on large welding jigs where part tolerances vary, relying on the fixed NBR bumper to absorb the 30-500mm/s approach impact.
Pallet Lift Stations
Adjust the lift height limits on-demand for different pallet sizes without swapping cylinders, while the unaffected retract stroke ensures consistent downward cycling.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ125X150-100S the Right Cylinder?
Selecting this 125mm bore provides massive thrust (up to 1251kgf at 1.0MPa). If 0.5MPa push is insufficient, no larger bore exists in this series, but dropping to a 100mm bore lowers the 0.5MPa push to 3927N. A fixed-stroke ACQ suffices if your extend position never requires tweaking. Confirm the 150mm total stroke, 100mm window, PT3/8 port, M22x2.5 female rod end, and the -S magnet when ordering.
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 ACQJ125X150-100S FAQ
This cylinder delivers 6135.9N push and 5733.8N pull at 0.5MPa, 8590.3N push at 0.7MPa, and a maximum push of 1251kgf at 1.0MPa. The usable extend range is 50-150mm (150mm full stroke minus the 100mm window).
No, the adjuster only limits stroke length, not piston area, so force remains identical to a standard ACQ. The cylinder relies on fixed elastomer bumpers for end deceleration and does not hold loads on air loss; for fail-safe holding, install an external rod lock or pilot-operated check valve.
