About the Airtac ACQJ12~25 Adjustable Compact Cylinder ACQJ20X60-10SB
The AirTAC ACQJ20X60-10SB is a double-acting JIS compact cylinder featuring an external threaded stop with a lock nut that limits the extend end position. You can fine-tune the usable extend range from 50 to 60 mm on the machine without swapping parts, while the retract stroke remains unaffected. It includes a male M8x1.25 rod end and a built-in piston magnet.
Because the adjuster only alters stroke length and not piston area, output force stays identical to a standard ACQ of this bore. The 20 mm bore generates 157.1 N push and 117.8 N pull at 0.5 MPa. Fixed elastomer TPU bumpers at both ends handle end-of-stroke deceleration, and the integrated magnet works with reed or solid-state switches.

| Adjuster thread | M8×1.25 |
| Port size | M5×0.8 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.15 – 1.0 MPa |
| Proof pressure | 1.5 MPa |

| Speed range | 30 – 500 mm/s |
| Rod thread | M5×0.8 (F) / M8×1.25 (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 (Ø20mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 157 N | 118 N |
| 0.7 MPa | 220 N | — |
| Max (@1.0 MPa) | 32 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 ACQJ12~25 Adjustable Compact Cylinder ACQJ20X60-10SB Is Used
Machining Fixture Stops
Dial in the exact clamping reach on a CNC fixture, allowing operators to accommodate varying part lengths without fabricating custom spacers.
Packaging Changeover
Adapt the extend endpoint rapidly during product format changes on a packaging line, ensuring precise positioning for different carton sizes.
Prototype Positioning
Establish optimal trial end positions for a new assembly station, tweaking the extend distance by up to 10 mm before finalizing the mechanical setup.
Is the Airtac ACQJ12~25 Adjustable Compact Cylinder ACQJ20X60-10SB the Right Cylinder?
If you need less force, the 16 mm bore yields 100.5 N push at 0.5 MPa, whereas stepping up to a 25 mm bore provides 245.4 N. This 20 mm option is ideal when your application requires roughly 157.1 N of push force and exact extend positioning between 50 and 60 mm. If the end position never varies, a fixed-stroke ACQ cylinder is sufficient. To order, confirm the 20 mm bore, 60 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 ACQJ12~25 Adjustable Compact Cylinder ACQJ20X60-10SB FAQ
It provides 157.1 N push and 117.8 N pull at 0.5 MPa, 219.9 N push at 0.7 MPa, and a maximum push of 32 kgf at 1.0 MPa. The full stroke is 60 mm with a 10 mm adjustable window, giving a usable extend range of 50 to 60 mm.
The external M8x1.25 threaded stop with lock nut limits only the extend length, so force remains identical to a standard ACQ. Fixed elastomer bumpers decelerate the rod near stroke ends, but the cylinder will not hold its load on air loss; use an external rod lock for fail-safe holding.
