Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ125X50-10SB
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ125X50-10SB is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø125mm bore and 50mm 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 ACQJ125X50-10SB
The AirTAC ACQJ125X50-10SB represents the big-bore JIS compact pneumatic line, engineered for double-acting single-rod operation. An external threaded stop with a lock nut restricts the outward travel, delivering a usable extend span of 40 to 50 mm. The inward return motion remains at the standard 50 mm. Because the piston area stays constant, output force mirrors a conventional ACQ of this size.
This Ø125 mm unit integrates a male M30x1.5 piston rod end and a PT3/8 port. It carries a fixed NBR elastomer bumper at each end to decelerate motion near the travel limits. Equipped from the factory with a piston magnet (-S), the body accepts both reed and solid-state electronic switches for position sensing.

| Model | Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ125X50-10SB |
|---|---|
| Series | ACQJ JIS compact adjustable-stroke cylinder |
| Bore size | Ø125 mm |
| Full stroke | 50 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 ACQJ125X50-10SB Is Used
Heavy Press Tonnage Setup
Dial in the exact 40-50 mm extend distance on a large metal forming press without machining custom spacers for different material thicknesses.
Automated Welding Gun Calibration
Fine-tune the electrode approach on robotic welders to accommodate varying joint gaps, preventing excessive electrode wear.
Palletizer Product Changeover
Quickly alter the pusher end-stop position when switching between different pallet sizes or box heights on heavy-load packaging lines.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ125X50-10SB the Right Cylinder?
If your setup requires less thrust, scaling down to the Ø100 bore yields 3927.0 N push at 0.5 MPa, whereas stepping up to the Ø160 bore provides 10053.1 N. A fixed-stroke ACQ is adequate when your end-position never varies. To order this adjustable variant correctly, confirm the 125 mm bore, 50 mm full stroke, 10 mm window, the -S magnet for sensing, and the -B male M30x1.5 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 ACQJ125X50-10SB FAQ
The usable extend range is 40-50 mm. It delivers 6135.9 N push and 5733.8 N pull at 0.5 MPa, 8590.3 N push at 0.7 MPa, and a maximum push of 1251 kgf at 1.0 MPa.
The M27x2.0 external adjuster limits only the extend stroke; force remains identical to a standard ACQ. The fixed NBR bumper decelerates motion near stroke end, but a plain cylinder does not hold loads on air loss. For fail-safe holding, install an external rod lock.
