About the Airtac ACQJ12~25 Adjustable Compact Cylinder ACQJ16X25-10SB
The AirTAC ACQJ16X25-10SB is a double-acting JIS compact cylinder featuring an external threaded stop with a lock nut that limits the extend stroke. You can fine-tune the extend end position directly on the machine without changing parts, yielding a usable extend range of 15-25 mm (full 25 mm stroke minus up to 10 mm). The retract stroke remains completely unaffected by this adjustment.
Because the piston area is unchanged, the force output is identical to a standard ACQ of this bore, delivering 100.5 N push and 75.4 N pull at 0.5 MPa. The cylinder body uses a compact C-clip design with a fixed elastomer bumper at each end for end-of-stroke deceleration. It includes a male M6x1.0 piston rod end for direct load coupling and an integrated piston magnet (-S) for position sensing.

| Model | Airtac ACQJ12~25 Adjustable Compact Cylinder ACQJ16X25-10SB |
|---|---|
| Series | ACQJ JIS compact adjustable-stroke cylinder |
| Bore size | Ø16 mm |
| Full stroke | 25 mm |
| Adjuster thread | M6×1.0 |
| Port size | M5×0.8 |
| 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 | M4×0.7 (F) / M6×1.0 (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 (Ø16mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 101 N | 75 N |
| 0.7 MPa | 141 N | — |
| Max (@1.0 MPa) | 21 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 ACQJ16X25-10SB Is Used
Product Changeover Stops
Adjust the extend stop up to 10 mm shorter on packaging lines to quickly set new end positions for varying carton sizes without disassembling the cylinder.
Trial End Positions
Dial in the exact clamping depth on lab testing fixtures by turning the external M6x1.0 adjuster thread, finding the optimal travel before finalizing the setup.
Setup-Varying Fixtures
Modify the extend stroke on small pick-and-place modules to handle different component heights, using the full 25 mm travel or shortening it to 15 mm as needed.
Is the Airtac ACQJ12~25 Adjustable Compact Cylinder ACQJ16X25-10SB the Right Cylinder?
For sizing, the adjacent bore 12 mm yields a 56.5 N push at 0.5 MPa, while the larger bore 20 mm provides 157.1 N, making this 16 mm bore the right middle ground for light actuation. If your equipment never requires varying the extend endpoint, a fixed-stroke ACQ cylinder is sufficient. When ordering, confirm the 16 mm bore, 25 mm full stroke, 10 mm adjust 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 ACQJ16X25-10SB FAQ
The usable extend range is 15-25 mm (25 mm full stroke minus the 10 mm window). It delivers 100.5 N push and 75.4 N pull at 0.5 MPa, 140.8 N push at 0.7 MPa, and a maximum push of 21 kgf at 1.0 MPa.
The external M6x1.0 threaded stop with a lock nut limits only the extend stroke length, meaning force remains identical to a standard ACQ since piston area is unchanged. The cylinder uses fixed elastomer bumpers for deceleration, and the -S magnet works with reed or electronic solid-state switches.
