About the Airtac ACQJ12~25 Adjustable Compact Cylinder ACQJ25X45-10SB
The ACQJ25X45-10SB is a double-acting JIS compact cylinder featuring an external threaded stop and lock nut to fine-tune the extend end position. With a 10mm adjustment window, the usable extend range runs from 35mm up to the full 45mm, while the retract stroke remains completely unaffected. You can dial in the exact stroke on the machine without swapping components.
This bore 25 variant includes a male M10x1.25 rod end (-B) for direct load coupling and a built-in piston magnet (-S) compatible with reed or solid-state switches. It uses fixed elastomer bumpers for end-of-stroke deceleration.

Specifications follow the official AirTAC ACQJ datasheet. The adjustable stop shortens the EXTEND stroke only; ACQJ is double-rod, so push is lower than a standard ACQ of this bore. Adjustable window options: 10/20/30/40/50/75/100 mm.
Theoretical Output Force (Ø25mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 189 N | 189 N |
| 0.7 MPa | 264 N | — |
| Max (@1.0 MPa) | 39 kgf | |
ACQJ is double-rod: the rear rod that carries the stroke adjuster passes through the rear cover, so both piston faces lose rod area. Push is shown at the annular-area value (conservative), lower than a single-rod ACQ push of the same bore. Actual usable force is lower due to friction; size with a safety margin.

Where the Airtac ACQJ12~25 Adjustable Compact Cylinder ACQJ25X45-10SB Is Used
Machining Fixture Stops
Dial in the extend range from 35 to 45mm to accommodate varying raw material thicknesses on a milling fixture without machining new spacer blocks.
Packaging Changeover
Quickly reposition the external stop to adapt product pusher end positions during format size changes on a packaging line.
Assembly Trial Positions
Establish the precise 35-45mm extend end point during prototype assembly machines before locking down the final mechanical hard stop.
Is the Airtac ACQJ12~25 Adjustable Compact Cylinder ACQJ25X45-10SB the Right Cylinder?
If your setup requires less push, the bore 20 version provides 157.1N at 0.5MPa; stepping up to bore 32 yields 402.1N. If the end position never varies, a fixed-stroke ACQ cylinder is sufficient. When ordering, confirm the 45mm full stroke, 10mm window, S magnet, and 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 ACQJ25X45-10SB FAQ
The usable extend range is 35-45mm, created by a 10mm adjustment window on the 45mm full stroke.
An M10x1.25 threaded screw with a lock nut limits the extend length without changing piston area, so force remains identical to a standard ACQ. The cylinder uses fixed elastomer bumpers instead of adjustable air cushions, and it will not hold a load on air loss without an external rod lock.
