Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X125-10SB
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X125-10SB is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø160mm bore and 125mm 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 ACQJ160X125-10SB
The ACQJ160X125-10SB is a big-bore JIS compact cylinder engineered for double-acting operation, featuring a 125mm full stroke and an external extend stop. A threaded screw with a lock nut restricts how far the rod travels outward, giving a usable extend range of 115 to 125mm. You get on-machine end-position tuning without swapping parts, while the retract stroke remains completely unaffected.
Fitted with a male M36x1.5 piston rod end and a PT3/8 port, this unit delivers a push force of 10053.1N and a pull force of 9424.8N at 0.5MPa. Because the adjuster alters stroke length only, the output matches a standard ACQ of this exact bore. The body incorporates fixed NBR elastomer bumpers at each end and magnetic-switch grooves, requiring the -S magnet to trigger reed or electronic solid-state sensors.
Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X125-10SB Technical Specifications
| Model | Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X125-10SB |
|---|---|
| Series | ACQJ JIS compact adjustable-stroke cylinder |
| Bore size | Ø160 mm |
| Full stroke | 125 mm |
| Adjuster thread | M36×2.0 |
| 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 | M24×3.0 (F) / M36×1.5 (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 (Ø160mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 10053 N | 9425 N |
| 0.7 MPa | 14074 N | — |
| Max (@1.0 MPa) | 2050 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 ACQJ160X125-10SB Is Used
Press Tonnage Setup
Dial in the exact 115-125mm extend endpoint during heavy press tooling changes without machining new spacers for each die set.
Woodworking Positioning
Fine-tune the clamping reach on large panel processing lines, relying on the 14074.3N push at 0.7MPa to secure heavy timber.
Assembly Line Changeover
Shift the outward stroke limit by up to 10mm on the fly when switching between large automotive component variants on a single fixture.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X125-10SB the Right Cylinder?
Selecting this 160mm bore provides 10053.1N push at 0.5MPa; scaling down to a 140mm bore drops the push to 7696.9N, whereas moving up is beyond the standard range. A fixed-stroke ACQ is sufficient if your extend endpoint never requires tweaking. Confirm ordering essentials: 160mm bore, 125mm full stroke, 10mm window, the -S magnet, and the -B male thread. Note that a plain compact cylinder drifts on air loss, so deploy an external rod lock for fail-safe holding.
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 ACQJ160X125-10SB FAQ
It yields a push of 10053.1N and a pull of 9424.8N at 0.5MPa, 14074.3N push at 0.7MPa, and a maximum push of 2050kgf at 1.0MPa. The 125mm full stroke features a 10mm adjustment window, allowing an extend range of 115-125mm.
An M36x2.0 external threaded screw with a lock nut limits the outward travel, leaving the retract stroke untouched. The piston area remains unchanged, so force equals a standard ACQ. Deceleration relies on fixed NBR elastomer bumpers, not adjustable air cushions.
