Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ125X10-10SB
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ125X10-10SB is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø125mm bore and 10mm 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 ACQJ125X10-10SB
The ACQJ125X10-10SB is a big-bore JIS compact pneumatic cylinder engineered for double-acting operation with a single rod. It features an external M27x2.0 threaded stop and lock nut that restricts the forward extension, providing a usable extend range of 0-10 mm from its 10 mm full stroke. The retract distance remains completely unaffected by this adjustment. Because the piston area is unaltered, output power stays identical to a standard ACQ of this size.
At 125 mm bore, this unit delivers 6135.9 N of push force at 0.5 MPa. It includes a male M30x1.5 rod-end thread for direct load coupling and a built-in magnet (-S) compatible with reed or electronic solid-state switches. The design relies on fixed NBR elastomer bumpers at each end for deceleration rather than adjustable air cushions.

| Model | Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ125X10-10SB |
|---|---|
| Series | ACQJ JIS compact adjustable-stroke cylinder |
| Bore size | Ø125 mm |
| Full stroke | 10 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 ACQJ125X10-10SB Is Used
Heavy Press Tonnage Calibration
Dial in the exact 0-10 mm extend position during heavy press setup, allowing operators to fine-tune contact without fabricating custom spacer shims.
Automated Assembly Line Changeover
Adapt end stops rapidly during product family changeovers on large assembly machines, reducing downtime when switching between thick and thin components.
Prototyping End Positions
Establish optimal push distances on new welding fixtures by testing various extend limits safely before locking the nut down for production runs.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ125X10-10SB the Right Cylinder?
When sizing this big-bore variant, consider the neighboring 100 mm bore which yields 3927.0 N push at 0.5 MPa, or the larger 140 mm bore providing 7696.9 N. If your equipment never requires on-the-fly end-position tuning, a fixed-stroke ACQ cylinder is sufficient. To order this adjustable model correctly, confirm the 125 mm bore, 10 mm full stroke, 10 mm 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 ACQJ125X10-10SB FAQ
It provides 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 10 mm extend window allows a usable forward range of 0-10 mm.
The M27x2.0 external threaded stop limits only the extend stroke length; force remains unchanged because the piston area stays the same. The cylinder uses fixed elastomer bumpers, and since a plain ACQ-type does not hold loads on air loss, an external rod lock is recommended for fail-safe holding.
