About the Airtac ACQJ12~25 Adjustable Compact Cylinder ACQJ20X15-10S
The AirTAC ACQJ20X15-10S is a double-acting JIS compact cylinder with a single 10 mm rod, featuring an external threaded stop and lock nut that limits the extend end position. You can fine-tune the extend stroke on the machine without changing parts, yielding a usable extend range of 5-15 mm (a 15 mm full stroke minus up to a 10 mm window). The retract stroke remains unaffected. The adjuster uses an M8x1.25 thread.
Because the piston area is unchanged, the force output is identical to a standard ACQ of this bore, delivering 157.1 N push and 117.8 N pull at 0.5 MPa. The cylinder body is a compact C-clip riveted design, and the -S suffix indicates a built-in piston magnet compatible with reed or electronic solid-state switches. Fixed elastomer bumpers at each end manage end-of-trroke deceleration.

| Bore size | Ø20 mm |
| Full stroke | 15 mm |
| 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 ACQJ20X15-10S Is Used
Product Changeover Stops
Adjust the external stop to quickly set new extend end positions during packaging line format changes without swapping hardware.
Trial End Positioning
Dial in the exact extend point during laboratory testing or assembly machine setup to find the optimal contact distance safely.
Setup-Varying Fixtures
Accommodate varying workpiece thicknesses on a single fixture by tuning the extend stroke within the 5-15 mm usable range.
Is the Airtac ACQJ12~25 Adjustable Compact Cylinder ACQJ20X15-10S the Right Cylinder?
If you need slightly less force, the adjacent bore 12 model provides 56.5 N push at 0.5 MPa, while the larger bore 25 unit offers 245.4 N push at 0.5 MPa. If your extend end position never varies, a fixed-stroke ACQ20X15 cylinder suffices. When ordering this adjustable version, confirm the 20 mm bore, 15 mm full stroke, 10 mm window, the -S magnet for sensor grooves, and the default female M5x0.8 rod-end 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 ACQJ20X15-10S FAQ
The usable extend range is 5-15 mm, created by a 10 mm adjustment window on a 15 mm full stroke. Force is identical to a standard ACQ: 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 retract stroke is unaffected by the adjuster.
An external M8x1.25 threaded stop with a lock nut limits the extend stroke, changing stroke length only without altering piston area or force. Fixed elastomer bumpers handle deceleration at both ends. The -S magnet works with reed or electronic solid-state switches in the body grooves.
